Exclamation nitrous benefits on turbo car...

Is it true using a small amount(25-35 shot) of nitrous on a turbo car will decrease intake temp drasticly and of course from that give you more hp from that. Where would you plumb it if you installed it(before the throttle body)? any opinions or thoughts would be great.

p.s. im talking about a dry system.

I have never used nitrous, but have helped a friend install and tune a wet setup on his car(98 Regal GS). It is true that nitrous will give larger gains to forced induction engines due to thier relatively higher intake charge. But non-intercooled applications will see the best gains from a small shot of nitrous. On my buddy's 98 GS, he cut .4 off his E.T. with only a 25 shot.
Btw, if you plan on using a dry system, you have to install the nozzle before the MAF, so the PCM can compensate with extra fuel, or you'll lean out. That's why I wouldn't install anything but a wet system.

Talking

on my dry system it has a fuel pressure riser that attaches to the fuel pressure regulators vaccum line. supposively when you hit the nos it creates a vaccum and make the fuel pressure rise, but i have never used it. In that case i would think you wouldn't plumb it before the maf but after it.

Um, NEVER install nitrous before a MAF. Well unless you like converting a $200-300 MAF to scrap. These things run at several hundred degrees on the wire. Sudddenly you are runnign a very dense gas that is below freezing across it. Mmmm broken maf.

Just get a decent NOS system and follow the instructions.
