nitrous before the turbo on exhaust

[80monteturbo]

i attend wyotech and one of my teachers is a huge turbo guy. but either way he say that it is possible to run nitrous after the last manifold before the turbine a small shot and it would make the turbine spool faster cause it makes the burn hotter. he say it helps alot. the only thing is to watch for is the turbine gettin to hot and melting the turbo or the turbine transfering the heat through the metal onto the intake side of the turbine. but that a coating could help keep the heat on the exhaust side.

i was wondering if anyone has done this or ever heard of this. cause this was completely knew to me.

I haven't heard of that, but I know that a small shot in your up-pipe will help spool.

Afterburner effect,stay clear of exhaust tips.

Nitrous does not burn. It would be like shooting compressed air into your exhaust manifold. That may help spool from the pinwheel effect but unless you have extra fuel and an ignition source then you won't get a hotter burn. With no fuel to burn it would only cool. Exhaust gasess would be hot enough to release the O2 and maybe even hot enough to detonate the fuel but I don't see how you could get a controlled burn. It may explode or it may burn slowly enough that you get your afterburner . If you want to use nitrous for spool up then just put a small wet shot in the up pipe and gain all of the benefits of putting the power from the extra fuel to the crank and not just out of the tailpipe.

I have heard of something similar using a SMOG pump to introduce extra air. At WOT, most poeple run on the rich side and their is extra fuel to burn. Don't know how well it works. I doubt the increase is substanial or we would all be doing it by now.



On an '80 Turbo V6, a tighter turbine housing off a 82/83 turbo would help spool up.
