2 stages

#1 Post by dcw9360 » Sat Jun 25, 2011 9:22 pm

Was wondering if most people leave on big kit then bring in a smaller kit...or the other way around????
Big tire car and can handle 350 now.....but want to add 200 for 2nd kit...
Any input????

Thanks... :scratch:

Depends on what the car wants, but in general the goal is to get it all in as fast as you can. So if it's taking a 350 off the bat, sounds like adding the 200 as a 2nd kit would be the way to go like within the first .7 to 1.0 second range.

If your second stage is on a timer you might be better to bring it in sooner rather than add hp.

I run 400 hp off the line and another 300 on a timer which I vary from .4 of a sec up to 1 second depending on the conditions

You add 700 HP worth of N02 to your ride ? Is that where the 'Chevyfireball' nickname comes from ? :mrgreen: :mrgreen:

Geez louise, that's gotta be like hitching a ride on the space shuttle at liftoff. :shock:

If you don't mind my asking, how much are you making on motor and what sort of times are you turning ? Is this 1/8 or 1/4 mile ?

Yep, I was right. It's *exactly* like the space shuttle except without all the orbital insertion stuff.

2050 hp. Wow.

Ok holy stromboli that's a lot of power. I was 16 when I first joined a group of adults who were racing. I was in it for three years, and our first year we used a 1970 challenger r/t with a 426 and a supercharger. Ran into the low eights. I'm trying to get back into it, but it's been so long, I need to refresh a bit. When you have two stages of nitrous, are they both built into the tune? Or is the first one in the tune and the second one manual?
