I usually use r42lts gapped at .030, read and heard from people using an 8 or 9 cold heat range is better for turbo or nitrous cars......any comments on that??
 
I run the R42's as well. R42's should get you running pretty fast. I havent had a chance to do back to back runs with 41's vs 42's.

Could it would it.. dont know. Great question.
