Default 100 shot dyno numbers

Finally put the car on the dyno for some numbers plus the 100 shot.
Results were 455rwhp 437 rwtq and a perfect A/F. I may be pulling a little too much timing so those numbers are a little conservative. The 100 shot comes on at 3200 and goes to 6100.

The next step is adding a 50 shot 2nd stage that comes in at 4900 and goes up to 6200 and raising my shift points to 6300 from 6200.


Not too bad on a stock short block.

I was curious on what kit you have and if it's wet or dry.

My sig has all of my mods. It's a NX Gemini MAF system and it's wet. I would only use a wet kit on an LT1 as I do not believe that the computer in them is quick enough to make the fuel adjustments that you can get away with on an LS1 and I do not like the method of raising the fuel pressure as it will give inconsistent results and you may damage your motor. It's a basic that N2O needs more fuel added and I prefer to tune the jetting myself.

No matter which kit you use nothing beats tuning and checking it on a dyno with wideband.

Just curious what were your A/F numbers off and on juice. I'm getting a lot of conflicting info on perfect A/F on nitrous. Thanks for any help.

The 11.6 is pretty good A/F with a 100 shot. As the size of the shot goes up you want the A/F to go richer than that.
