So I am starting to run in TT4 with NASA, and will need more power to get to my 12.0:1 pounds / HP ratio (per NASA's average calculator methodology). The car weighs for arguments sake 2700 lbs on the nose with me, coolshirt cooler, and a 1/4 tank of e85 as it sits now NA.


Questions :
What does the JRSC kit weigh roughly? <-- FOUND ANSWER, roughly 55 lbs?


For my target of 12:1 pound per HP, I need roughly 235 hp peak WHP. Should the C30 with the standard pulley get me there on e85?


Understanding that it's inherently risky boosting a motor with static 12.5:1 compression - with a good tune, are the FA20s surviving at the "lower" whp levels like I'm targeting? This one may be directed more @CSG_Mike, but any track beaten JRSC cars please chime in More referring to lifting rings / heat related issues, and not so much starving the bearings due to g-load on hoosiers :haha:
