660R01, How did you do? I dont own a Mootang!

 

nice wheely bar Moose. Do you have an extra?

 

No extras, we got it right the first time!!LOL

They can be had, "For A Price"!!

 

I don't want to upset you Raptor guys because I know I'd get hell for it! Just by going up to 22/23" razrs on my DS, I was able to hit 82.6 mph on a Magellan 315 GPS. That was with everything stock except tires! Now, I was doing this on ice and had about 2 miles to reach that max speed. If I were doing it on pavement, I would stick with the 20" tires to minimize the rotating mass and just go with a tooth or 2 bigger on the countershaft sprocket. With the gains you're getting by just adding a pipe to your Raptors, you should not have any problem pulling the taller gearing. Also, you Raptor guys better get a wheelie bar or strap a winch on the front of your machines!!! Or may I suggest watching from the stands?[img]i/expressions/face-icon-small-wink.gif[/img](shouldn't have said that one!!!)

PS-Getting an ATV to run 13's in the 1/4 is dang near impossible on a stock bored engine. I would imagine piped Raptors could do about a 14.7 1/4 mile and thats with a good start. It's all in the start, and you Raptor boys got a lot of work to keep that front end down!

 

With your mild mods, I think you could easily pull a 15 tooth front sprocket without loosing acceleration. Take some main jets and dial in for maximum speed!!

 

I have 2 mustangs. But I have only ran one at the Track.. but I am a big on Ford type guy.
