Launch (1st stage) 3.5 psi on the gate is getting us to 8 psi of boost on the launch. 1st stage with no delay set at 26 psi on the gate get's us to 24.5 psi of boost. 2nd stage coming in 1.5 sec out has 28 psi on the gate making 26.1 psi of boost. I think that we can bring the boost in a little sooner and I got a couple little tricks I want to try with the timing below 7K RPM to smooth out the graphs. We also need to come up with a cold air intake as the air is currently being picked up dead center behind the radiator.
I am gonna have to try stuff cause I don't like wheelies. Think I am gonna call you now in fact
Oh and grats again to everyone who had a hand in.

Many guys never get the opportunity to be involved in a project like this. While I have spent some time wrenching on this thing, most of my work has been done behind the keyboard between researching, spec'ing things out and tuning. It's the stuff that I like and Steve was good enough to believe in me as this turbo **** was all really foreign territory for both of us only a short year or so ago.
HUGE THANKS TO ALL THE GUYS THAT HAVE CONTRIBUTED ALONG THE WAY HERE ON TECH. Almost everything that I have learned came from here. Years ago a guy would have had to figure all this **** out on his own. This is the main reason that I felt compelled to do the build thread. To give a little back. Thx again everyone.

This thread has really caught my attention. If I can move a 555 BBC I have I will be looking to do something similar in an early Chevy. Tuning race cars/street cars at the track is fun, especially when they are someone elses. 
awsome

Wow I am jealous of that for sure I came out on 7.5psi launch and the first stage ramping 6psi per/sec to towards 22psi and that gave me a bumper tap. You guys must have done something else better then I did else where.

Fireball's car didnt use a ramp either, just shows your turbo isn't coming up on boost fast enough with a 422". If your not getting 25-27psi of boost per second you need to revisit the setup. So you should be at 24# of boost at .78 seconds into the run.

The ams1000 going from a launch setting of 3.5 psi to 24.5 on the first stage is the ramp. If I put 18 psi on the launch to 24.5 on the first stage the car will go on the bumper and make about 25psi of boost in less than a second. I have two broken input shafts because of those settings.

We are intentionally not getting into boost that fast. On the passes that it went on the bumper, we had 23 psi within .9 sec. Right now we have it getting up on the 2nd stage 1.2-1.3 sec. It's liking that. Will probably need some training wheels to bring it in faster than that. The 3rd stage can come in a little sooner though.

I'm not sure where you guys get E85 up that way, but the only place I have even seen it is the rest stops on the turnpike. I haven't seen it at any gas stations here in Broward. When I lived in Chicago it was everywhere!

For those who haven't seen this car in person, it looks even better in person. Craftsmanship is second to none. Congrats again!
