Sorry, I'd like to borrow your thread... I run a 04r last night, FDR of 7. After a 3k pack, the motor (yok 23T) is quite hot, but still could touch it for around 4 seconds++ before the heat really got to me. The car is very punchy through infield, but lacks top end on the straight. Is this a sign I should gear up the pinion a tooth?
TIA! and apologies I have not run a mod motor b4 can't help there...
