My friend has a b7 with a JRC. It runs 14s. He's a road racer, not a drag racer.

Until recently I was running the same setup with a 4-1 header. On that motor you can hit 7psi before having to worry about temp issues. But, that's pretty common among the d-series motors. The JRSC for the D-series isn't nearly as efficient as the latest K-series which can hit 12psi before extra cooling is required.

You can use a small shot of nitrous to cool the intake charge.

Yeah, but anything over 7psi and you'd be pumping nitrous regularly. That'd get expensive versus water/methanol injection.

You could also use water.

You would use it only while racing. Not all the tme.
Then what's the point of cooling the air charge? You'd need it daily just to drive the thing. The jackson hits max boost at 3600rpm. I have too much of a lead foot perhaps.

I have a jrc but will i need to modify my bottom end?
no, you'll be fine running it on there. I ran the boost upgrade on my stock bottom end with 180,000+ miles on it with no problems

^^ how much can a dseries jrsc be had for these days?
A fair price for a used "complete" kit is around $700. It may be possible to locate a new kit stashed away somewhere, but they haven't been produced for a couple years.
