See if you guys think this would work. My dad is an old school hot rodder...he runs a 55 chevy with a big block and nitrous...what if I was to put nitrous jets to spray across the top of the intercooler to cool it down instead of a water spray kit...filling the small nitrous bottle wouldn't be a problem since my dad fills his own bottles....by the way...my dad's car is fully street leagal and runs mid 10's in the 1320...pretty quick for that heavy car..

Umm, why not just shoot it INSIDE the intake stream? It'll cool your charge ALOT more and give you a much bigger boost in power.

nitrous is not flammable, just read the bottle

While nitros is non-flamable, it is absurdely cold when it comes out of the nozzel. Spraying it directly onto a hot IC may cause the IC to crack. That would be very bad, and could lead to catastrophic engine failure. That would be even worse. I say, stick to water, it's what they use on WRC cars, so it can't be that bad for your ride.

I agree. The nitrous adiabatically expands when released at high pressure, resulting in a dramatic temperature drop. Cool enough to crack already-hot steel. Bad idea.

But like Phast said a lot of guys use the nitrous to get the damn turbo to spool faster. You can rig up a system so when the RPMs get above 3k the nitrous turns off. But I am sorry about the Chevy thing. Mopar forever!

Well yeah, nitrous is meant for creating power *in* the engine, but not *on* it

LOL Great point but to get the nitrous to cut off at certain point would help the RPMs get up to where the turbo could take over.

Yep, JWT uses nitrous "spool up kits" for my ZXtt too. Totally eliminates lag and make s the car drive like a big-block V8. Which may or may not be good because my car cannot hook up in its powerband anyway

Kinda scary, actually. The car's got 265 series rears and still doesn't hook up completely. One of the reasons I'm getting an AWD rex... traction!

But I will miss her power

265? That's it?! Try some good old 375's. If it dont hook up then you got a killa on your hands! :lol:

Hehe, I could fit 275s but if I wanted wider I'd have to delete the HICAS rear wheel steering to do so.
