Dyno'd it - not happy at all....

All chassis dyno's are different. You can not compare numbers from one dyno to the other, they are just tools to use at your disposal for generating numbers. As long as you continue using that particular dyno for changes and seeing results. That is why every magazine you read, they try to do a baseline dyno before any changes, cause the dyno's will be different. But I agree with Red82Gt on your altitude.

There is alot more to how much fuel your engine gets than just fuel pressure.

Pulse width- On mass air cars the pulse pattern of the injector can be lengthend or shortend to add more fuel to match the air flow that is metered by the amss air sensor.

With your mods 19# injectors @38psi will easily handle it.

Rule of thumb to remember: Lean is fast, Fat is safe. This holds true for all, but us nitrous guys take it to heart. Like mentioned before, you want it to run as lean as you can, but without detonation. All an internal combustion engine is, is a big air pump. Get the air in, and get it out as fast and efficiently as possible. The fuel makes the air mixture explosive, and that's what drives your air pump. Extra fuel in there takes up space that we could put more air in, and actually takes longer to burn. Once the flame front starts across your combustion chamber, too much fuel means it's still burning even after your piston is long gone. Then we have too many spent gasses to get rid of on the next stroke as well. There's A LOT more to it than that, but in a nutshell more fuel WILL NOT make more power, unless you add more air to go along with it.

If you take a trip back there, have him print it out. Everything from the runs should be saved. 1.15 sounds about right for the correction factor. I have seen numbers that high, here, in the middle of July when its 100 degrees.

The guy operating the dyno sounds like he did everything correctly. The only other thing I do is look at the uncorrected numbers.

Thanks for all the info!

It was a Dynojet 248. I will see if I can get another printout with the a/f ratio.

Anyone have any idea of how many ponies might be hiding in my stock h-pipe & cats?

Probably 15-20RWHP.... You should have ditched that crap long ago
