They don't have a true USGT class so I don't have a choice but I figured the 17.5 action would make me a better driver. I can keep up with some of the 17.5 guys with my VTA car so I'm hoping the 21.5 would be awesome to run against them. Thanks for the FDR advice. I'm gonna shoot for 3.1 to start.

Picked up a Hacker 21.5 and was told that I needed to turn the timing all the way up and then 1 more 'tick' to get top performance from the motor. Well, the little extra 'tick' gave me all the speed I was sorely lacking but now my motor temp was at 185 F when I checked it about 20-30 seconds after the end of the heat race.
Track temps were around 110-120f, air temps were about 105f, so the motors were starting out already warm. I do run a fan on the motor as well
1: What temp would be considered too hot?
2. Running a 5.5 fdr for our class, and I'm running a 113t spur and a 40t pinion (5.65 fdr). Would dropping down a tooth on the pinion be advised to reduce the temps, or are the 185 degree temps within a safe parameter?
Thanks in advance for your input.

Don't go there... because the the only possible answer pertains to appearances and if appearances matter, then why allow racing prototypes...?

We run a local Nastruck class using bodies like these, and it's both fun and popular. The rules are the same as for USGT except for the bodies and tires. We use HPI Vintage Slicks with Vintage stock car wheels. The tires have very little traction, but last the whole season.

I like the truck bodies too. I'm fine that they aren't legal for USGT, but I wish there was an on-road class where we could use them. Maybe an open sportsman class like they used to run in Indianapolis during the RCAR days.

((counting down the seconds until someone produces pictures of trucks at some full size event)(I will not be swayed!!!!!))
