It seems they have almost thought of everything. I just spent like 30min or so reading all the FAQ stuff on their site and I am pretty stoked.

Their Meth kit when coupled with the dual stage boost controler makes things ultra safe. It can be set up to arm teh Meth kit when your flip the boost crontol button to hi AND it can be used to default back to the low boost setting when the Meth kit runs out of fuel or is not pumping for some reason.

The fact that the turbo is mounted so far back you end up with about the same cooling effect as a standard front mount turbo system with intercooler and less pressure drop.

I also didn't truely understand how turbos worked. I assumed they were like the superchargers I was familiar with but got their energy form somewhere else. I didn't realize they can hit full boost at such low RPMs depending on load. Now i can get a smaller cam, stop spinning my motor so high, and have near full boost @ WOT throughout my whole rpm range! That is just crazy.

Now I have to see if my AS&Ms are a waste for this type of setup. If so maybe I can sell them and recoup some of the cost of this system
I would guess you'd have more lag with the asm's. I know you want to keep exhaust velocity high with a turbo setup.

I'm interested to see what your IAT's are to see how well the length of pipe intercools the air. Do you have efi live to log data?

That's kind of what i ws thinking. I don't have EFI Live but my tuner does and we do very extensive data logging and lots of drive around time to monitor whats going on.

According to their data:
We typically get at least 50% Intercooler Efficiency numbers from our systems and some of the truck systems which have better exposure to cold air are even better. Combine this with a pressure drop of only about 1/4 to 3/4 psi and it makes for very good numbers.
Testing on our LS1 prototype produced the following results:

Turbo outlet temps at 5 psi boost were 175F and intake temps were 115F which is about 52% efficient.

Turbo outlet temps at 8 psi boost were 225F. This is a 50F increase with only 3 psi added to turbocharger boost. Even most large, expensive intercoolers have a pressure drop of at least 2+ psi. This causes the turbocharger to have to work harder to create 2-3 or even more psi to force the air through the restriction of the intercooler to get that much less boost into the manifold.

So in comparison, with our intercooler efficiency of 50%, combined with virtually no pressure drop, yields in all actuality, a better intercooler efficiency number than the 50% because with a standard pressure drop the temperature difference would be 225F at the turbo and 115F at the intake manifold which would require nearly 70% intercooler efficiency to produce.

With my procharger, I see about a 60 degree rise above ambient at 11psi after about 14 seconds WOT.

With the alky injection, as long as you keep the tank full, it should take care of IAT's

Do you have a stock exhaust system after the headers?

Yeah. I have the stock Y with gutted cats, stock piping the rest of the way back with a Magnaflow which will be removed to fit the Turbo. I am gonna try to go without a muffler and see how it sounds.

I am unsure about my headers. It just feels so wrong to think that long tubes would be useless for HP but that is almost the way it seems in this application. What do you think?

Thank you for your advice. I've always been supercharged or N/A so this is totally alien to me.

I've read a turbo is 1/3 of a muffler and a straight through like a magnaflow is 1/2 a muffler. So I don't think it will be much louder.

If I were you, I might leave the longtubes on and see what happens.
