TNT nitrous dyno run.....graph looks similar to 2001 GTS\'.....
My '97 GTS now has a TNT nitrous sytem on it. We took it to the dyno this evening to see what it's doing. This is the first time I've ever dyno'd my car at this location and the 2nd time dynoing it ever. The car has a K&N intake setup, a B&B exhaust and Autolite 3923 plugs in it. This graph is the baseline pull and the final nitrous pull. the system is jetted for a 150 shot, but the A/F does some funny stuff. The graph looks a lot like "2001 GTS'" nitrous dyno.
The bottle pressure was @ 975 psi. The jets are .025 fuel and a .042 nitrous. These are SAE numbers.
Is there any way to smooth out the nitrous run? The TNT systems, from what I was told run quite rich and they like lots of bottle pressure to help compensate. On the baseline run, it looks like the car is running lean by itself. But then with the nitrous there is a lean spike when the system hits and then it goes very rich.
What do you think?
Thanks for the replies!
