anyone out there know how fast a stock 2001 thundercat will go top speed and the difference a black magic whoop a$$ kit would make

ive heard 120s for top speed. ive also heard that bm doesnt make all that good of products, but i cant say for sure. its just what people are saying. id still say that the kit would make a little bit of a difference though :)

Just remember a clutch kit will not make a sled faster, it makes it quicker. Gearing produces speed.

the top speed of that sled with mods at all will not be high. you can look at 110-113mph. with an air box mod a clean up of the base and bored out carbs you will bring the speed up.with all these mods then you can look at say 115mph -120mph. again this is based on what i have seen and tested in my erea. i know speeds will vary from place to place.

gamer-
instead of wasting your hard-earned $$ on black-crap kits ( just my opinion), I would strip the drive train and look at things like jackshaft and driveshaft bearings and mounts, also all bearings in the skid. Check all shafts for trueness when you have them out. Make sure that your 2 gears are in perfect alignment with a straight-edge. Always use synthetic gear lube in the chain case. Make sure your clutches are aligned correctly, and your belt deflection is within factory specs. Any "rolling resistance" that you can elimate by doing these things will give you way better top end numbers than ANY clutch kit---especially from B.M.!!

Gamer, it all comes down to whos setting up the sled. I've run with some t-cats that did'nt impress me that match, and on the other hand some that would rip your face off with the same amount of $ and testing. When setup right, a 115-120, in trail form is easy for these sleds.......

My buddy's '01 has a clutch kit set up by his dealer (not sure what the springs are), 192 studs and main jetting down 2 sizes from stock. No airbox mods yet. Sled ran 119.5 mph on GPS on a very smooth lake in Ontario last year. Most of the time it's around 114 or so. The sled runs very strong.

As for BM, I can't say how good their pipes are but I bought my sled with a BM clutch kit already installed and its now out. Didn't like it at all and largely because of it my buddy whooped my arse everytime last year. A situation I plan to have corrected this season :devil:

My 2001 T-cat would run about 115-117 on rader (no where close to my 98 T-cat) But after spending a bit of $$$ (speedwerx pipes, DD powerbreater,V-force reeds,offset timing and of course clucth and gearing I was running 125 on rader, If you want to have a T-cat run like its supose to run you will have to make a few mods( 99 models on up)otherwise the twins will stress you out,if you get mods go speedwerx, DD, Simmons or PSI these guys know there stuff.
BEERMAN DID YOU INSTALL YOUR PIPES YET????? :hallo1:

I got them on just in time for it to hit 55F at the end of March. There was still ice on the bay but it was very sloppy. With the high temps and I believe a malfunctioning Tempaflow it was an unproductive day. It was running way fat and I was having an impossible time figuring out what to do between the plugs not looking too bad but 1500 EGT temps. I knew there was no way it was lean so I stayed into it at those temps and compression was still ok after 4 runs adjusting the tempaflow between each. The Tempaflow is now sitting on a shelf.

The sled had 6000 miles on it so I figured it was time for a freshening. So along with a top end rebuild it's being trail ported, shaving the heads, CDI from Jeff Simon, and of course the clutch being completely redone. With these mods and those pipes (thanks again) it should be stupid fast this year.

And I should be telling everyone how mild the sled sounded with the Speedwerx/CPR pipes. It sounded slightly meaner than stock, but it wasn't noticably louder.

i was out last year with a 2000 tcat for about 6 hrs. i have to say it sounded really sweet, but i dont think it was set up like it could be. in the trials he could not get away from me. i did notice that he seemed to be spinning more than any other sled that was with us. this may have been the problem. but man they do sound some nice dont they. :D

A TCat does pretty well in the trails for a heavy sled, but even in normal trails, let alone tight and twisty, a good rider could leave one behind on a ZR500. Now get on a long, straight road or lake and it'll be a different story.

Of course a ZR800 is certainly no slouch.

My 2000 T-Cat goes 114-118 all day with only Vforce reeds installed.

I did extensive testing with gearing last year and contrary to what some people around here say my T-Cat will not pull them without adding any horsepower.

This year I am putting on Jaws Pipes, Thunder Products Dial-a-Jet (they sound awesome now that I know how they work), Thunder Products TPI Valves for more air (Don't like D&D's idea of moving my coils and CDI and toolbox).

I am hoping these mods are going to work out.

Black Magic gets a bad rap around here as a moderator from this forum tried to get free stuff from them and they wouldn't give.
I even reported bashing to the moderator and, not surprisingly, recieved no reply as I was reporting bashing from the moderator himself!

I had a BM clutch kit put on last year and had a little problem out of the gate but that was due to my gearing changes, the kit works great. The shifting is just awesome. I phoned BM about my little problem and Tim himself solved it for me.

If people think Black Magic stuffs sucks I seriously suspect these people of either not knowing, not installing correctly, or bashing.
Seriously now, do you really think they would still be in business with next to no snow in Minnesota for the last two years?
Nobody knows performance parts for Arctic Cat sleds better then BM, period.
I would trust anything they sell and make sure you follow the instructions and you will be set!

Let us know how those TPI valves work out; they look like a great idea.

My limited experience with BM was a good one. I had a super single with chip and BM clutching in my '99 600. It flat-out ROCKED compared to stock. I didn't like the engagement notches in the primary weights, so I changed those, but after that it was great.
BTW, clutch weights with those notches will stretch out a drive chain in no time, from that harsh engagment.

Thunder, I didn't care for the harsh engagement of the BM clutch. And on my sled it engaged too low and would not shift all the way out. But in all fairness to BM I did not call them and ask for help. The kit was already installed when I bought the sled and it's very possible that it was setup incorrectly from the start. Glad you've found a company you're happy with. And I have to agree with your idea of if they're still in business after these last few winters they must be doing something right.

Hey guys, I think a proper setup is key. BM's clutch kits are too universal and always require more tuning than just bolting them in!
Check out this website. Check out all the results. They are real world. Rules are strict. My friend runs these radar runs. All big(fast) sleds are cc'd. A well tuned stock Tcat should break 120 in 2000ft.

For what it's worth, I've always been impressed when I've dealt with Tim (Blk Magic) at the shows or on the phone. He's always been approachable and willing to talk sled-talk with the public. I have never purchased major items from him, but haven't ruled him out either for future needs. Like some of you have said, he wouldn't still be involved in Cat's racing program if his stuff wasn't up to par.

I've met Tim at the sled show in Toronto a couple of times, very good to talk to.

Jim thats the problem, he aint involved in cat's racing program anymore, sure he builds cat motors but the factory guys use speedwerx or D&D, maybe that should tell you something. :doh:
