mk2g60 - Nice to have ya here. We have an older small arm L+S and have a couple of wuestions. There is a number stamped in the torque arm (blue) is this a Max torque #? We recently broke the arm and replaced it with on that is as long, but a different shape. We re-calibrated using a 80 lb weight, but wondered if we could go to higher torque. The old arm was good to 125 ft. lbs. and she broke at 127. We are sure it is good up to that, but wondered if this new arm will allow us to go to higher torque.

welcome mk2g60...I went to your net site and spent two hours looking at your product...I'am very intrested in your product...I read that *it comes with three egt probes...is it capable to run four egt probes for a four cyl. snowmobile race engine and how do you setup the air/fuel ratio device for four carbs. ...if you start with a baseline on a motor being that your product uses a water break and make modifications to the motor (example *pipes, porting, different carbs etc.) and you retest the motor and the gallons of water per minute flowing thru the water break is more or less will this influence the testing...I'am sure I will have more questions...thanks for your help...Al

800MXZ, are you guys making 127 torque with that ZRT800?

Will you be at the Port Huron (MSDRA) race this weekend?

Thanks, Chris

800mxz- the torque arms on the current models are good for at least 200 lbs of torque, think it's actually 225-250.the numbers should be a pn or a reference #.so if you replaced yours recently it should be able to hold up to some torque.

Al-having 4 egt's shouldn't be a problem, our v8 dyno's run 8.they are always making new programs so should be able to set u up with what ever you want.if you go to the tech questions link on the web site you can ask one of the sales reps all about the different set-ups.they should get back to you right away.

Toydoc - Well, I guess the cat is out of the bag. Yes, our asphault sled (97 ZRT 800) pulls 127ft. lbs. HP is 202 @9400. It is like a diesal pickup though, pulls 110+ft lbs from 8300-9500.

I will not be at Port Huron, as I am in Chicago at the IMTS trade show for work! Wish I was there though. I have been helping out Mr Cudney this year at the MSDRA races, but will not be at the PH race. I will be at the rest though!

Here is some pics of the asphault sled, everything is the same, but we (Kim Frank and I) modified a set of 900 D+D mod pipes to work on this motor chassis now.

Dam that's one heii of a zert man! I'm curiose as having been a proud owner of a PSI 1350 once. I spent about 7k for all they did to my motor for 235 trail hp. About what have you spent? Will you tail it at all this winter ?

Here is the ZRT. Note the factory cyl. 38MM stock carbs, factory head, etc... No fancy bought over the counter stuff here. Just good ol R+D. If anyone is serious about Cat tripples, I recomend talking to Kim Frank@ Secord Lake Marina.

Best times on the sled: 9.98 Sec @132 MPH, using ETT suspension. Sled is NOT a pro stock. All parts other than the airbox and tool kit are there. It is actually heavier than stock with the 53 lb track and all the extra wheels.
