Nitrous??
IN general, with a TPI system, how much nitrous could I feed to the engine without having to add all sort of difficult to control and expensive stuff?? how to allow extra fuel??
I suppose it's possible to put that cold start injector inline again and use that.....
what is the best and safest way to do this??
and is it even worth it considering the power it may make???
now much money we talking here??

Norval tpi's can run a wet system i use one ive run 150 shot im now running a 125 shot in it.YOu tap off your fuel rail,ive upgraded my pump to a walbro 250.I also use a zex tps controller.When the tps sees 5 volts at wide open throttle it grounds solenoids to open them.The mustang gt i had before i ran a dry system.One downfall to the wet system is it could cause fuel puddeling in the intake plenum.

OK, I would preferr to run a 'dry' system, just seems simpler to me,....maybe put the 24 lbs injectors back in....21s are in there now....so the O2 can react fast enough?? interesting...did't think that was possible....so how much HP for a dry system?? OH, this is a TPI 355 ci forged slug engine with around 60k on it...iron heads....

with forged pistons you could go 150 or be safe and do 100-125.i ran a dry setup on my mustang gt from brand new to 66,000 miles on it used it every day 2 bottles in the car.My boss had a grand national and we raced every night going home from work.I had a free supply for awhile in my friends back yard tank.Had a modified setup that used 175 shot,motor never failed me.

A dry system is also very simple to install.

I'm going to start with 50 and see how its goes from there. If I go below a shot of 75 you dont have to do anithing to the car no tuning or nothing is that true?

and i agree but once you try it youll be hooked and want to move it up,but i agree start low.its very addictive.only thing with a 50 shot youll hardly notice it,but try it and go from there.

TPI Nitrous
I used to run 200+ with a wet nos system on my 85 vette with TPI. The key is to make sure you have colder plugs, pull some timing out, do not run the engine with spray when it is really hot, make sure you run some better fuel and make sure you have a good running engine. If your engine is a rag to start with it is not going to like getting hit with 150 or 200 horsepower. However, if your engine is in tune and running strong you should have nothing to worry about. Nitrous by itself is not the problem in most cases...it is detonation that will kill you. Understand that just about any engine with stock rods and pistons will withstand 450 to 500 horsepower...your issue is not really the horsepower as much as it is engine RPM and if you are running a TPI I am guessing you are not spinning it really high. I would NOT recommend running a dry system and for the most part most of the nitrous firms have moved away from them.
