I've heard people running a system that has an injector in the intake tube. Does anyone make a plate that fits behind the TB that can be adjusted from 50-125. I have also heard of a problem w/ it puddling in the plenum and backfiring. Is this ture. Any help is greatly appreciated.

freebird, read this, made sense to me http://www.sc3gfb.org/resources/nos.html

hope this helps, Jim

 

Yeah, I was thinking about this myself. I'm assuming you're looking for a fogger system that injects N20 and gas through the same nozzle.

I know that TPI isn't designed to have gas flowing through the plenum/runners, so I was wondering if anyone had opinions on this, is it good/bad?

 

Hey SLP-GTA... could you please tell me where you got the kit for 465.00??? I'm thinking of buying it. Is it hooked up yet?thanks

 

The plate kit is #5151. The dry fogger system requires electronics, the "wet" plate system does not.

I have a line on a NOS system from a buddy of mine.. he wants 350bux for it. Does the wet system cause backfiring, like the original question states?

Freebird, have you ever heard of Rick Linstedt? He is in NC. Hell of a nice guy, he has a direct port Nitrous system that has a fogger for each cylinder. Each runer is tapped and has a fogger nozzle. He would be the guy to talk to about direct port systems on TPI engines. I have personally run a single fogger nozzle in the intake bellows. It works, though - some people have concerns about leaning the back cylinders out. Good luck.

To answer your question about backfiring....No, it does not any more than any other system. The only reason that would ever happen that the timing is too advanced (which you are not supposed to do anyway), or you activated the NOS below the recommended RPM (I know, I did it). Follow the rules and you dont have a problem. Been running mine for 5 years now.
