I'm getting a rebuild in the summer and want to take advantage of my new forged parts with some Nitrous. I was thinking about a 100-150 shot. I have a 305tpi and I think that 100hp should be safe with forged parts.

I have seen the common TPI kit from NOS that gives 100-150 shots and consists of a plate with a bar. However, I would ideally like a diret port set up but there doesn't seem to be any kits available out there. How would I get this?

I've also heard of some systems that have another chip that the NOS system switches to when it is activated. Should I be going for this system instead?

Basically I want a safe setup that ideally had direct port fogger nozzels. By the way, is it easy to plumb in the nozzels to the tpi runners? Plus will I need anything else like a new fuel pump etc?


Thanks for the help

no it isnt easy to install fogger nozzles. its a pain, and a waste if you only want 100-150 shot. the foggers are cabable of delivering 100-500h.p. of juice, they require extensive fabrication including drilling and tapping ports in your intake, plumbing hard lines, adding a second fuel pump for the shot, and if your smart you will install some safety devices like a low oil presure switch, air/fuel ratio monitor etc.
if i were you i would stick with the plate. its simple to install, and a whole lot cheaper.

I agree with the above poster about the plate thing. You can run 100 - 125 shot on a 305 with cast pistons fairly safely as long as the mixture is right so with forged pistons your in pretty good shape for a 150.

Is the bar setup a wet system? What's the difference betwen a wet and dry ststem? I've heard that dry is better but why is that?

Also, does the NOS TPI kit come with the extra computer chip, or am I thinking of another kit?

Thanks again

The NOS TPI plate system (5151) is a wet plate system. The differance between wet and dry systems is a wet system take both N2O and fuel and injects them under the carb or behind the throttle body. Both N2O and fuel travel through the intake. A dry system is when only the N2O has to go through the intake and the fuel is most likely added through the injectors. Therfore the fuel doesn't have to travel through the intake.

Is there any advantage to using one system over another? I've heard people saying they don't like the wet system. Is it likley to cause more damage?

Thanks again

the dry would add fuel via the injectors with a vaccuum line attached to the FRP I would suspect.

wet will pull its fuel an inject it via a jet from the fuel rail. I would DEFINATELY add a inline fuel pump no matter what kit you use. The NOS inline or Vortech T-rex will be good for the application.

I would run a wet system. If it is installed per manufactuers recommendations/instructions then it will provide good longevity
