The HP these new turbos are making are going to require more high dollar parts and fab to keep up with the top dogs IMO. There are quite a few teams with $ now and its only going to get faster.Well it's an interesting topic. These turbo motors with injectors and a good tune are making as much power as the ecotecs pushing class 10 cars around and we know those cars are fast. So without some limits I think you run the danger of someone just building basically a class 10 with a UTV engine and running wild. Keeping the diff, axles etc makes sense.
I just think the car counts are so high because basically anybody can buy one from a dealer (financing baby!), and with some reasonable garage skills and race parts put a decent car on the track. I think the number of people who are gonna spend class 10 (or more) type money on a UTV is much much smaller. I love the fact that UTV racing has exploded, hell I bought my first UTV just a couple months ago after seeing what they can do....it would be a shame to turn it into a class where you can't win a race if your car isn't $100k plus.
Anyway a friend got a few of these yamahas into the shop a few weeks ago and they are undergoing desert race surgery. It will be interesting to see what they come up with. Are there many yamahas racing desert and if so how are they doing? At first blush I'd wonder how stock size axles and cv joints would hold up with the geared trans.
As far as the Yamaha it think the jury is still out on the rear suspension design for desert and the front suspension pivot points are only about 6 inches apart.
If the 75k price for a RG built Arctic Cat is true and gets to race pro production it just might be a bargain. Unfortunately I didnt get to get in it at the 1k but everything about them screams pure race car. Thats what I love about this build and hope it kicks ass.
