Gotta be careful with drive pressure on nitrous. Run a turbo with a good sized wastegate or a large exhuast side housing otherwise you'll be picking it up off the floor. Lower rpms help also.

I would not think a stock turbo would be a good set-up for a nitrous truck.

My truck LOVES the nitrous... so far... :lol:

Have you hit a dyno with it yet?

Needs LOTS of fine tuning, only 376.63HP 675.99TQ Uncorrected w/ a .082 jet @ 950psi. I might be loosing alot on the tranny though. Its daves low end convertor, steping up to the big one this winter. Every one said it sounded like alot more, even mike (dyno operator) said that number looked real low.

I also run a lot of nitrous in my duallie. I run two stages. First stage is on a hobbs switch set to about 25psi and the 2nd stage is on a wot switch. I can't remember exact jet sizes but I think 1st ones an 82 and 2nd ones a 96. I need to upgrade my feed line and get a bottle heater thou. For timing I run a jumped tooth and a little more then the stock mark and when the nitrous comes on it pulls like crazy. Still need more though, egts don't drop enough yet and theres still smoke lol.

I'd say the dyno guy got in it way too late also for the 3200 spring if the RPM on the graph is right. I make peak power at about 2600-2800.
