he has a svt...which jrsc uses the last gen m62 blower, that blower at 10psi wouldn't like it for a long period of time and you would have to solve the the tuning problem that the car will severely need along with fuelmicrotonal said:The standard JRSC comes with the M45 blower(3-5psi max) from what people have said on this forum.
I think with an M62 blower you might be able to get 10 psi.
You'd have to call them and ask. If you get the new Ford Focus handbook, they use an M62 blower on their SC for testing. I can't remember what the highest psi was with the M62 but I know it was 6 psi or better.
