Nos to spool up? Ive been fiddling with the idea of throwing a relatively small shot of nos 50 to 75 to spool up faster for a while now but just not sure..
-Any of you guys have experience with spray to reduce lag?
-Does it work well enough to justify doing it?
-How much faster does your turbo spool as apposed to no spray?
-How much can you spray before you blow the spark out?

I had a 75 shot with a 408 LS with a 88mm turbo.
It worked great while I had it. It would only come on for a second or so as the boost would come on pretty quick. I had a hobbs switch that shut it off at about 4-5 pounds of boost. From a roll it would work great. I never tried it at the track as I just would use the trans brake to launch it.
I originally put it on for roll racing but then thought it was kind of dumb to roll race the car so I only had it on the car for a few hits and then took it off to save the weight.

I won't be launching on the streets just highway pulls. The boost threshold on 80mm and up turbos on 5.3 is pretty high, I'd like the spool up a little faster with out having to shift and lose a little time. To counter act that I could probably get different gears in the rear maybe 3.27 or lower. I have 3.73s currently. But like I said nothing set in stone yet just trying to weigh out my options...

My old set up was a 5.3 with isky triple 12, fast 102 intake with a Borg Warner s480 running stock 80e with a hd2 trans go kit and 3.73's. I'm debating on wether to go with this same set up on my new motor (if I can get it to spool a little faster or if I should go small twins. Like 70mm or something along those lines. Before I was hitting full boost around 4400-4500.
It works great. Get a super tight converter and taller gears to take full advantage of it. Hit it with a 100 shot for 1-2 seconds, then shut it off. It's a night/day difference. Seems like you'd be out of gear fast with 3.73's roll racing? Are you going into OD? what does the converter stall to?
