I have several nos brand tpi nitrous plates and solenoids and was wondering if this has been done before by someone on here or if this is a good idea. My SBC is all forged internals and built for nitrous as I have a single plate on currently. But I'm thinking of adding a second stage with another plate. Any suggestions or ideas ?

 

it has been done with carb plates, so i would imagine it would work with the tpi plates. however, the tb will be moving foward over an inch, so some things may not work/fit anymore. i would wait and max out the first plate before stacking, and by that time you will probably be over a 200 shot... and at that point i would probably switch to a different intake. lol

 

Yeah my buddy did it with a carb plate intake. Up to 350 hit but never on a front tb plate.

You could get a plate to feed upwards of 200-250 hp no problem but beyond that i would look at a single plane or direct port since most front fed intakes have some level of air distribution issues

 

Any distribution issues should be the same (N2O and fuel would have the same distribution) with a well designed wet shot.

I don't know how much you want to spray, but an NX shark nozzle will spray up to 250hp each reliably if you really want a plate type setup it would be very easy to make one with a shark nozzle mounted in each bore supporting up to 500hp, well more than I can imagine anything fed with a TPI intake will take reliably.

 

Yeha the fuel and nitrous coming out of the plate may be evenly mixed but that doesnt mean that it makes its way to every cylinder the same. Some cylinder may get more of it than others and unless you do per cylidner tuning, you can have issues

I saw uneven distribution with a wet nozzle on my hsr at a 150 shot
