Nitrous Jet # Question.

[tanglewood]

Ok, got the bottle filled last night and gave it a test fire out of the intake tube and the guy said that sounded a lot bigger than a 25 shot...

I got 5 jets and they are labled/stamped with numbers.

My card references like this: Small 39, Medium 49, etc... Not anything about HP.

The jet in there has 39 stamped on it. Is that the 25HP Shot?

That is around a 50HP shot assuming 45lbs of fuel pressure and 900psi of bottle pressure.

Here is a website to help in caculating hp levels based on jet size.

.039 with the stock 55psi fuel pressure and 1000psi nitrous is about a 68hp shot and should result in about a 58 RWHP gain. .024 should be about 26hp with a 22 RWHP gain.
