I do asphalt drag with my 1991 650 in Atlantic Canada, just wondering if anyone does any asphalt drags? What machine? what are your best E.T. & MPH??

I m running an 97 Indy 500. My best mph was 103mph. what all have you done to your sled?

I bought this sled with all the mods done, bored out, Wisco pistons, pipes, smooth bore on the carbs, asphalt suspension, best 1/4 time of 10.96 @ 115 mph.

is 103 good for a 500?

103 is about right for an Indy 500.

This summer I plan on running high 9's-low 10's @130mph in my Mach Z.

OMG! ur all crazy!! 115 on a sled......thats crazy better not smile bugs might get in your mouth LoL sweet none the less!

Thats what helemets are for :thumbsup:

Years ago I use to run a drag car, so I can sure appreciate the speeds you guys are turning. Must be a real blast!!!

It's a blast alright Can't wait to get back on this year, and hope to dip a little lower in the 10's!!Hey mtrsprt where do you race? Any mods done to your sled??

I haven't raced on asphalt yet. Hopefully this summer.

My Mach Z's engine is somewhat apart waiting for the cylinders and head to come back to me.

Should be about 190hp when I get it back together. I would be running at New England dragway in Epping NH.

I found a guy who will sell me a drag track for 100.00!!! He says he only has about 30 passes on it!!!!!

I have been running since 1998 and my current sled went 10.40 @125 last year and should be quicker this year. I'll find out in 2 weeks.

Polaris 650 guy. I did run my rx1 at the Miramichi Dragway last summer. It's alot of fun. The best time for me was 11.10 at 115. The track I bought was worn out, right to the canvas on the edges. 60 footers suffered 1.58 was the very best.
Once last year their was to guys from the island one with a tcat and the other with a storm. They invited me to come to the island to race but I did'nt make it. Good lads. I also got to bye another rx1, I wrote mine off last week. My buddy's got a turbo'ed rx1 he wants to sell, if I can get the right price. That shoud be good for high 9's or low 10's. How many sleds would show up to race at osyter bed each time?

I bet you boys have fun. We have a blast on the MSRF ice circut, but it's too cold.

Asphalt is similar to ice, except it's bracket racing. what fun it must be w00t

Hey guys I was wondering what all I could do to my 500 now. I was getting info from polaris indy 500, but you guys removed him. He was really helping me! Can anyone tell me what else i could do to get my sled goin faster?

Hey 1XR, those two guys you met on the Island I know them and they have helped me out ALOT!! It depends on the week-end at Oyster Bed, but I have seen up to 30 bikes/sleds. I am now in Fredericton, hope to run at Miramichi this year-might see you there!! A couple of us are trying to put together a Bike/Sled week-end at oyster bed around august this year, will let you know if we can get organized!!

I am going to be trying this out for my first time this summer. My buddies race asphalt with MACH1's. I will get there times and speeds.

2 weeks and I start playing on the asphalt again.
w00t w00t w00t

My asphalt season is starting this saturday cant wait !! I believe after some tuning my Machz 925 will be running 9.2's-9.3 140's we will see it ran 9.9's 128 last summer as a ported 800? Now its race ported and a little lighter plus 10.5" track alot less rolling weight. Let us know how you do this summer as it goes.

All right you guys I'm ready to convert to asphalt. I was just curios where all of you buy your equipment from. I have a 700 mxz that i've been grass dragging and doing radar runs with, but the races are far and few between, and I have a 1/4 mile drag strip 30 min from the house. Any information or tips would be greatly appreiated. If any one has any decent used skis or tracks forsale let me know.
Thanks, Andy SWRules

Andy, there are lots of used tracks around. If you buy new then get the narrow 10.5 wide track. Add wheels between the slide rails and don't run any on the outside with either track.
As far as skiis go. You can make your own. 3 1/2 flat aluminum for the sides and put idlers wheels in for your wheels or look for an auto parts store that carries the DARCOR caster wheels part # W-PLE-404. They are a bearing wheel that are made for asphalt shiis. They are $50CAN each here. 4 wheels and some alum and you have brand new skiis.

good luck

well.........only got 2 passes in before the rain came in.

Cold track no traction but the little 700 still pulled off a pair of 6.7s @ 100mph.

What are you running?? 1/8 mile, 800ft,...??

1/8
Traction was bad only 1.53 60 fts.
Usually run 1.40 60s and sled usually run 6.5s @ 102.
I am trying to get mph up to 105 and runnning 6.3's

Sounds like you had as good luck as me , I only got 1 run in had voltage issues making the tach quit at wot? So without a tach couldnt attempt to dial the 925 in plus 60ft was 1.69 not good as you know .3 off from last year and pretty much all the way down track 6.5 660@109 and 10.32 127 , I am running tom. have all the bugs fixed hope to get into the 9's at least ? good luck

Polaris 650 ,have you run on the Sydney track in Cape Breton .Normally
between 20 or more sleds at each drag racing meet.I think there is
5 bracket bashes this summer , I have seen guy`s from the Island there a
couple of times (P.E.I.) that is. I used to run for three summers but it hard
with work ,sure would love to get the new Firecat out there though.
Cape Breton Stock.....................In `96 ran a 95 600 ZRT (stock bore
no porting ...just pipes D.D. triple race..turned 118.4 best at 11.22 )
This was a basic sled with a very aggresive trail set up in it..5700 rpm engage
with stock pipes...114.8 at 11.40 crappy 60 ft times for the most part.
Hope to see you run this summer.

caper711cc, have not raced at sydney yet, hope to get there someday, I have meet and raced some really nice guys & gals from there!! I will be racing in July at PEI. There is a Bike/Sled weekend planned for Jul 10 & 11, should be a good week-end!! There is going to be some bands playing Sat. Night and bunch of giveaways, hope to see you there!

went 9.95 @131.7 sat. but the clutching is still way off under rev. by 400rpm , went 115 in 660 but the e.t. was bad 6.42 , 1.62 60ft had 1.40 last year lots of work still.

i ran a 6.08 @111.24 in the 1/8 and my 60 ft is around 1.38, the average was 6.18 @109, but it should be better this year, swapped to a 10.5 track, it is a lot of fun, i almost hope it don't sell before the track set's in :D

do you care to share what sled and motor doo 900? Sounds like you are on the right track , I could use some clutch help if you are familar w/big bores? This is my first.

Dead attachment.

maybe this one ?

i give up i havent been able to post a pic yet , still learning

My little small block Rotax 700 triple is starting to come around. Had a best on the weekend of 6.49 @ 105 mph in the 1/8 with a 1.39 60ft.

1.39 in 60 ft is pretty good hooking, i got to a 6.06 @112.00 with a 1.41 60 ftr, she is coming around now :D :D

any idea what a 01 ZRT 600 should pull in the 1/4??

If you can run high 11's for 1st time out then you should be happy. Assumng it is stock.

yup shes stock besides a power breather. eventually ill play with the clutching

Running high 11's on a stock ZRT 600 would be pretty tough. With good clutching, and a decent short time, plan on times closer to the 12.5-12.8 sec times @ around 110mph.

what about 60ft times? i lowered the front of the machine down and adjusted the limiter straps. but how should i go about lowering the rear of the skid frame? i was thinking of using a ratchet strap? but that didnt seem like a safe idea..

The best way is too drill new holes and use smaller wheels up top. That will still give you the suspension tuning needed. Most will just use chain. You need 3 guys. 2 big to squat the sled and 1 small to put their hands in there to attatch the chain.
You want to keep a min of 2 inches under your belly pan so as not to affect the lights.
MTRSPT your 12.50s and 110 mph is more what a car or bike would do. You wonb't get the mph on a sled. They et real good and mph down when comparing.
A friend runs a stocl xcr 600(1995) and can run low 12's and I would bet the ZRT is a better pkg.

alright, i bought some cable and the cable clamps, worked great. the machine rolls really easy now, that should help me go a bit quicker down the track :hallo1: i think i need to go a bit tighter on the limiter straps. anyhow shoot me a PM about what tracks ya got forsale im interested in one :cool:

WENT TO LEBANON VALLEY DRAGWAY ON MAY 14 BEST PASS WAS A 9.61@ 133 MPH, TRYING FOR 9.5S THIS YEAR. GOT A FEW MORE THINGS TO TRY.

hey mtrsprt, i wrote you a reply to one of your older questions about clutching and setup on your machz.i also have done tons of stuff to my sled through the crnkshp.ported cyl,raised port timing, bored carbs,15.3 cr dome head and very aggresively clutched.she sits in a chassis that weighs 410# wet puttin out around 205-210 on 115 race gas.before i put the head on this yr my 1 and only time ive had it out so far i ran a 6.3 at 109 in the 1/8.had a 60ftr of 1.8 absolutely no traction for us yet.it will take me awhile to dial in my new whal bros asphalt sus,clutching etc.my exhaust temps were way down to 900-950 degrees and i need to be up around 1200 or so.nothing a few jet sizes lower wont take care of.well hope to here more about all of you guys experiences this summer.

:hallo1:

98' T-Cat 1000, Knapp trail porting, D&D trail pipes, nothing else. 15" track, stock suspension, 93 pump gas, everything works, handle bar warmers, thumb warmer, headlight etc... Trail riden in the winter. 589 lbs on N.E. Dragway scales plus rider. Ran 6.17 @114 in the 1/8 and 9.91 @130 in the 1/4. Run consistent 1.3's in the 60' Best going sled I ever had. Haven't even begun to tap into it, got so much I can do to it, I don't know where to start!

Mason, is that you?

AS77

hey bud, yes its me who else?i see you made it on here,pretty awesome huh?theres a great bunch of people on here, any questions just ask lots of answers.a couple of the best are Dynamoe^Joe for clutching and Bill Cudney for differant things too.beat you sunday,,,,,,,,i mean SEE you sunday. :devil: :nimrod:

:hallo1: I thought that was you! U get setup for your license yet?

nope,think im goin to wait till i have more time,too many things goin on this w/e you know with the sled shootout and all.im goin to be in the quick 8 this time count on it!!!im camping sat night r you?if so you'd better stay the he-- off corys 4 weewer,no more late night trips to the hospital :ohmy: well talk to you soon.

w00t AAAAH!!!!! I had almost forgot about that! Good times! I think the weather is going to be good, I'm HOPING the T-Cat will be there this weekend, who knows! I'll be there with or without sled! Have you heard from Joe? I hope he's doing alright,

talked to him the other day seems to be o.k but thats got to be he-- for anyone.hope u have your sled ready.jim's coming up sun too.cant wait goin to be GRRRRRREAT!!!

No Cat in Crowley's pit this weekend, I've got my ProLine completely torn apart to blueprint it and the guy next door has let me use his balancing maching to do all the idlers and drivers. It would scare you how bad those parts are out of balance! ProLine stuff is REAL good, but the aluminum drivers (which would have the most effect if out of balance) where pretty bad. So I'm doin it right the first time. Lotsa work though!

you just dont want to get your butt WALLOPED by that bada$$ z....lol :nimrod: :p

They way you got that Doo runnin, I MIGHT have to turn off my hand and thumb warmers! LOL

asphalt77, try to make it up to oxford plains speedway sometime.

there is a mach1 up there running high 5's in the 1/8th.
Another mach1 is being finished ( electrical) and he will be up there turning around the same times. w00t w00t

Run Oxford all the time, Jim Hyde (manager) is a good ####. I always plan to go when Crafts is going to be there and Stanley and those guys. Crafts was in the 5.52 (1/8) at New England last year, but I don't think he's run this year yet. I heard Phil Stanley went all the way to Kentucky to run exhibition runs! Don't know if that's true, but it's what I heard. Man, those sleds run. I'll be down in a couple of weekends to help a friend make license runs, we dumped ALOT of weight off the T-Cat this year and some "super secret" motor work, run a 6.17 on pump fuel and full trail gear, I'm pretty confident the 5's might happen for me, but who knows! Maybe see you there!

I have never personally done this, I hear its a blast.

do you know A&M sealed power?? Out of casco???

Heard of them, why?

Just was curious. The owner and a buddy of mine ( a few) race up there. the owner had his mach1 up there a few weekends ago, that i know of and pulle high 5;s

The other Mach1 owned by Mike Pasco will be running very soon. finishing electrical.

Do you know Danny Myer?? Myer racing? I did grass drags with them . they set me up. had a 99 mxz600 running really really strong in 500feet.

guy by the name of billy ( billy blue bottle) mxz800 on nos??? know him??

Don't know any of those guys, you know Mark Sjulander (shoelander)? He's got a NOS Ski Doo that runs pretty hard. Asphalted with us last year, ran ice this winter, he's from Hollis.

I think i know who he is. Has a 900 red mxz?????

I think it's an 800, but yes it's red. Goes good too, ran 6.4's last year. I know he's stepped up a little this year, can't wait to see it on the hot top.

i know which one your talking about now. there are two different sleds. this person is fogging his airbox with NOS correct??? crank shop pipes??? I raced his rev last year 03 with my 99 before I re clutched it and put chisels on it and beat him and his buddies 670ho? ( him and I went back and forth) but i got him best out of 4 races. he got me once :inlove:

He ran the black mxz800 from naples and flat out got it handed to him. also got beat by the mach1 that is still being worked on. sled did go good though.

A buddy of mine built this for asphalt racing. He took the "sled/bike" class a little too seriously.
:p

what can i say? absolutely AWESOME,what does it do for times and et?where does he race?krager r u on amsnows forum site ive seen your name i think.

i meant times and SPEED

I tried my rx1 turbo for the first time on the weekend. With 5 lbs of boost to get the feel of it, and a new 15 track. Times randged from 10.41- 10.57 and mph from 124-126 and terrible 60 footers from the best of 1.598-1.667.
I know with 10 lbs of boost and more than stock gearing that was toped out and some how get the 60 footers down to at least a low 1.5 would get a 9 something.

It is a stock storm motor with cobbled up pipes to fit the chassis. Runs low 6.3s at 115 mph with mid 1.4 60fts. He just went to a smaller tire for this weekend so it should accelerate quicker.
The same motor went 6.7s last year with an asphalt track and only went 100 mph.

I just started running my F5, best time so far was 12.78 @ 100.22mph, I put some speedwerx twins on and changed the clutching around, going to see how much it helps tomorrow.

*edit- best 60 foot so far is 1.75, still workin on that one...

Well another weekend of racing and took home a 1st on Sat and 2nd on Sun.

I have a 1994 t-cat. Last week I ran a 9.62 @ 135 mph in the 1/4 mile.
I really do not think a stock MACH Z will run a high 9 .
Maybe A high 10. My freind has a Mach Z that was built by Doug Flannery
he has 195 HP on the dyno and is running low 10. It takes major horsepower to run in the low 10 to 9 second range. Sounds like that 650 and 500 is rockin.

COCKTAILS IN 9 SECONDS!

My 180hp trail machz ran 9.99 @ 127 and 10.0's all day long , hp isnt the factor as much as weight and 60ft , my friends bone stk zr900 run 10.3's and he just found the crank out of phase? as for stk machz 10.6 was our best stk susp. and wt.

I can run 10.30 with my little 160hp 700 triple. Also ran 10.50s with stock piped mach z too.

no offense but it sounds like your friends machz needs clutching. i have the same hp and i run 6.2@1/8th at 114mph which translates somewhere in the mid 9's@1/4 around 140-145mph. this is a new sled and i havent got the bugs worked out of everything yet(susp,carbs etc.). it should be a 5.9-6.0 flat sled when its right,in the 1/8th at around 115-116.

Ya, you could be right on the clutching. Is that all you guys run is the 1/8 mile?
Looking at his slip I see he ran: 60 ft = 1.5
1/8 = 6.3 @ 109 mph
1/4 = 10.062 @ 126
My sled ran: 60ft =1.4
1/8 = 6.0 @ 115 mph
1/4 = 9.6 @ 135 mph

Any advice on what to try with clutching? No offense taken.
I was just going by what I have seen at the track here in Michigan.

should be able to bring your 60' times down a little too, my F5 should be in the 1.5's that should be low 1.4's high 1.3's with that much power

Went to the track on the weekend made 13 passes which is real good. But 60 footers were real bad, the rubber was gone off of the track. 1.645- 1.746 60's. best on Sat. 10.07 @133.92 and best Sun. 10.10 @135.12. Hope to find a 9 something with at least with a 1.4's or 1.5's 60's.

if you do any gearing and clutching try this, install a top gear that is 1-3 teeth LARGER than what you currently run. i know what your thinking gear up it'll slow down right? WRONG, within reason, trust me, the reason is that when you gear up you are giving the motor more of a chance to hook up witout spinning the track, not only that but when you gear up in your chaincase you actually force your clutching to stay in a lower ratio which is more efficient. your better off with tall chaincase gearing and low cluth ratio than vice versa ive proved this at my track 100 times over. as a matter of fact i switched from 23-43 gears to 26-43 gears this w/e and shaved 2tenths off my et. you got nuthin to lose by trying and it just might surprise you. as far as your 60's go have you tried dropping you needles to see if that helped? jetted down on the mains? keep one thing in mind if your not to familier with tuning 'ONLY CHANGE ONE THING AT A TIME OR YOU WONT KNOW WHAT HELPED OR HURT!!!!!!!!!!!!!!' you could also put a little more pretension in your secondary. let me know what happens and ill try to help from there, definately try the taller gear....it works. w00t :thumbsup:

I know that the gearing is still too low. I geared it up 1 before I went last weekend. Now I have 25/38 . But 25 is the largest top I can get for an rx1. I'll just go to a 35 bottom good for 142. Jetting a 4 stroke turbo is a little different I think. My traction problem was'nt right off of the line but out about 15 feet when the turbo went full 10 lbs of boost. I did'nt change alot of clutching but played with chassis changes. What I learned after about the event I went testing on was a sport compact car event, 90 percent of the cars were on street tires, spun all the rubber off of the first 100 feet. Allso the track people did'nt spray much track conditioner on the track. By the way it pulls and the mph it's got some hp. Thanks for the advise about the gearing and clutch ratios it makes sense, as long as the belt don't slip instead. Also will it make a difference by adding air dams and tapping off vents, it's still my trail sled.

machz1, gearing up may help but also may not be the answer. Gearing up will only compensate for improper clutching. You are staying in a lower ratio as to grip the belt...........if you figure out your clutching then you will allow better grip and able to use the whole clutch. I run an Avenger on my sled with jackshaft sensor which calculates my clutch ratio. on a 700 doo triple I run 22/44 and reach full over drive at about 660 ft - 700ft. The sled will run 125 mph in the 1/4 and only has about 165hp. I have cool clutches as well.
Machz1....get a hold of Dyno Joe. I currently use one of his helixs and if I told what the angles are ........or what I think they are(and I am close on this) you would laugh. But look at my HP and my mph and gear ratio. Its all about exploring new roads. I will never go back to runnning a helix similar to a 54/48 ever again.
Let me tell you that once I got this avenger with the sensors, I started to really learn about my sled. You wouldn't believe the amount your clutches are shifting in and out on a pass. I am now getting a nice clean pass. Just need to work on the first 1.2 seconds.....which is in my suspension. I currently run 1.43 60ft.

heres my summer fun!

machz1 looks good. Still using stock skid or aftermarket?

pic of mine with the airdam before I painted the light weight hood.

its aftermarket, wahl asphalt two, it hooks really well. i also made my own light hood, used to work in a boat shop,them skills come in handy dont you know....lol

heres a good one

This past weekend I managed to get into the 9's
went 9.85 a couple times, mph was up to 136.56. But 60 foters were'nt that great with 1.57-1.65. Who knows what it would run with a 1.40ish 60 foot.

a 1/10 in the 60ft will usually get you 2 in the 1/4

i need to get my 60's down.. I am in the 1.73-1.77 range... I know that is horrible, even for a 500. any suggestions? I have tried stiffening and softening the rear suspension. dialing up and down my front shock springs. I can get it to lift the skis 6" or none at all, either way i am anywhere from 1.73-1.80. I dropped my 8th mile by .3 when I get my skis up about 3" or so which dropped my 1/4 by .3-.4 but I just dont know where to go with 60's.

little info, stock F5, stock gears (19/40) engaging at 5300, rev's to 7k then shifts to 8k by 100ft or so. I have a dalton 52/46 helix, 50.5 gram weights, red/white secondary in second hole, pink erlandson primary. I have tried steeper start angle helixes, heavier weights, a real shallow 48/36 helix, all with diminishing results.

I still need to turn my oil pump down some more cuz it is still using too much oil, but the plugs' color is good, besides the extra oil on the threads. I am running 330 main jets.

This is my first year running asphalt, so I am still learning a lot. Having a lot of fun though. best run is now, 12.42 @ 101.76... not bad for a 500, but I really want to hit the 11's, I know its possible

is that pu$$y cat efi? if it isnt try playing w/your needles and pilots.does she puff alittle smoke off the line? does it feel like it pulls real clean all the way through? is the exhaust sound revy or alittle dull compared to winter time?

nah, 500 carb. I have been talking to a few people, and they are saying the best i will ever see with it is a 1.70 or 1.69 just because of the power valves not opening until the rpms get up. about 100ft out it comes alive once it shifts. no smoke. I have played with the needles, they are just about perfect, if i go up or down, i get a little hesitation. havent played with the pilots at all though exhaust sounds good. I have it revving about 100rpm less than in winter and that gets me the fastest times... I have tried a lot of different combos there, I am going to try a couple different helixes and see if that helps out a little. maybe a 54/46 or something like that

firecat,
sounds like your on the right track just keep playin youll get it. as for the power valves not opening ,that actuallt makes you quicker down low thats the purpose of doing that,basically when you close off some of the exhaust port at lower rpms it moves the torque band down lower to work with the lower revs. i would have to say that i agree w/your friends on the 1.6's as your best, i ran a 583 modded last yr and was running 1.49-1.55 steady.

I was also told that my track sucks for 60' times. my buddy runs consistant 1.37-1.39's at his track, comes to mine and runs 1.5's. I will be making it out to his track for some testing soon, so hopefully I will pick up a little there. I am havin fun though, that is all that matters right? :D
