Blew up my car last year on stock motor. JPC did a boss short block, billet oil pump gears, return style fuel system, some other odds and a tune. Car made 706whp on 93 on 9 psi. It's back down to 6/7 psi off the gates where it makes around 620whp. I plan on putting an EBC in soon and dropping the spring pressure down to 4/5 psi and then running 2 settings. JPC was more than patient with sitting on my car forever, huge favor by them. I have a few little kinks to work out still but the car seems great. Hopefully it stays together for a little while this time.
