Will this work for a 305 TBI or will there need to be modifications?http://www.nosnitrous.com/HiOctn/Pro...densystem.html

 

I don't see why the under-manifold kit wouldn't work. The air-cleaner one probably could be made to work with a bit of modification. Since the "sneaky pete" requires carburetor rejetting to compensate for the extra fuel required, it probably wouldn't work without some chip tuning.

 

Im looking at the top shot thing would that work? Not the sneeky pete thing.

 

You will need enrichment fuel....

TPI cars have the luck of taping into the schrader valve on the fuel rail. this works for low horse applications 100-125max.

The Problem with TBI is that the stock pump will not give you enough fuel pressure/volume You will lean out. Been there, done that.

The safest way to do this is to run a seperate fuel line with an inline pump and use lower pressure carb pills for the N2O and fuel. I used a Holley "blue" pump and 1/2" line to a underhood regulator and braided line to the fuel solenoid. The secondary pump only works when the system is armed. This guarantees an constant supply of enrichment fuel and if you ever want to spray more N2O the fuel system is already capable of handling it.

Then again I'm an **** SOB I sumped my stock tank and went from there. I even use an inline pump for my TBI since I hate having to drop the tank to service the pump. Twice was enough for me...

 

you can run a TBI nos kit with the stock injectors pump and everything...camaroracer1992 ran a 125shot all the time with the stock fuel systems...

 

I can't find a picture but there is another steath way to install N2o on any TBI system. It's like the topshot thing but that doesn't work with our injector pods being in the way. Instead it uses 2 fogger nozzles installed in the spacer ring. The tips are installed right next to the bore and aim straight down into the middle of each bore. This system seems to work really well since at WOT should be the only time N2o is used on a street car and so you will have the blades completely open.
You would need small nozzles and make it a custom job but it's worth it. If I had to do it on a TBI manifold that's what I would do.
Since I have a carb intake with the adaptor plate I'm just going to get a square bore plate kit since they're the cheapest around.
The only thing I need to be careful with is the fuel pressure since they're ment for low pressure systems and I might have to install a secondary AFPR in the return line and tap into that for the fuel delivery. Set that to about 8 psi and I would be set :-)
