no problem, but i would highly recomend using a wet system.It is a much safer system to use.On a dry system you are relying on the computer to add the fuel while on a wet system you are spaying fuel and the nitrous

I've been told a 100 shot can be a bit much for cast pistons.

I have been running a 125 shot on my stock LT1 for 2 years without a problem. But I would also say to run a wet shot.

I am guessing (hoping) that if he went through the bottom end to build a 383, they at least put hypereutectic pistons in it and those should handle 100 hp.

As others have stated, go wet.

It's ok to run rich on N20, it may not run good rich, but ok. Run lean and it's goodbye pistons.

Can you run a wet system with a super ram intake. My over all concern was 10.5 compression. Ive been told that 10.5 is to high for running nitrous. SRP pistons----dart pro 1 heads--- 219/225 comp cam.

I have run a best of 10.97 on the spray. This was on a day when the car ran 12.40 na. The kit I use is an NOS 5151 wet system. I have been quite pleased with it. On a chassis dyno, the 150 shot gave an extra 147 hp and 202 ft lbs of torque at the wheels.

as far as shots and amount a stock block can take i was surprised when realized my buddy has a 94 camaro and has been running a 175 dry shot for almost 3 years now. i have ridden many times with him before and he uses it all the time. he has quite a few miles on his car as well. only mods are bolt on mods. i would say you could run a 100-150 shot carefully and not have a problem at all

Dry systems use increased fuel injector pressure (sometimes as much as 80-100 psi) to richen the mixture; the fuel injectors used in our vehicles (and most others) are pintle type and not made to handle that type of pressure. Plus it's inconsistent UNLESS you size the injectors for N2O and use stand-alone EFI system or burn a chip to compensate for it.

The biggest thing you're going to run into running a SR is the fact that the rear cylinders starve for fuel when running a single fogger nozzle or a plate system. The problem is the massive plenum. A true Fogger in the runners is the best way to go; but a plate or nozzle if you don't run over a 150 shot will be adequate as well.

You can either use a universal wet single nozzle setup like many company's sell or you can buy the NOS TPI system (p/n 05151) which is a plate system. They list it only for the TPI Vettes/F-bods, but it works on LT1's just as well and is the system I usually choose for LT1 applications.
