I’d love to talk to your buddy because I want to know how he’s made 500+ whp without the damn thing exploding. Would love to push that kind of power on my RS someday
closed deck and forged internals. If he’s on an NX2 he could easily get 700 out of it. I’m at 30 psi on stock internals and making 475, blocks on the RS are hit or miss. I’ve known guys who have blown out the open deck doing anything over 25psi so it all depends who got a stronger block and who didn’t.
Dude is scratching the crap out of the paint. Great car getting some awful maintenance/paint etiquette. Btw, the Speed3 was the predecessor not the successor.
