Just like with any other internal combustion engine, manifold design has tradeoffs.

Do they not make crazy curly Q manifolds for the LS motors?

Hey Paul
I just loaded your m6 tune so you should be done in an hour or so.
I need to bleed the clutch and adjust the clutch master.

Some have asked about the turbos. They are T3/T4 62mm with 82ar.
Looking good Shanne. Better get on the ball. I will have my turbo set up on my new ride next year. Going to do some testing with the stock motor first Any one know many nitrous kits you can put on the 3 valve motors????? Going to try 150 and move on up. LOL Stay tuned for the 3 Valve testing/results.

It's because all the domestic guys are old farts that don't get on the computer much.. 
You have to give us a few days. So how long is it going to take for Mike to get rid of his KB? I know he was disappointed with his also.
Kris, I have more than headers here... I'll PM ya.

Shane will be chasing the same record I am so 9.4x's is the goal. Don't know how the 10.8 compression is going to effect the turbos. It should help but good fuel will be a must. I will tune it for low timing on the street at low boost. At the track I would want some good fuel but It depends on what Shane wants to do. The tune will have to be spot on.

Shane decided to use his old cam that was in the 402. It was speced for his PT88 turbo that was in the Camaro. I am sure it will be just a test cam to see where we are at. The cam may be totally wrong, could be right. We will soon find out.

Ya'll dont plan on taking it down to like 9.2:1... I understand that 8.5 or lower would really kill the drivability (since you won't be developing boost at low RPMs), but isnt the whole advantage to boost the fact that you can cool the air after it has been heated from the compression (therefore making it denser and eliminating some risk of detonation)? You not worried that your not using the turbos to the full advantage by keeping compression that high?

The way I look at the high compression in Shanes situation... It is going to make awesome power with very little timing/boost. The turbos will spool quicker and on the street on 93 on a safe (rich/retarded) tune its going to rape 99.9% of cars. Add meth, race gas, whatever else you can to bump up the timing/boost for huge power for when he wants to chase (or break) records on a race/track tune.

Power comes from lots of compression, lots of timing, lots of turbo. Just a matter of making it safe.
Even Frank has said he wont build another turbo motor using 'low-compression' ever again.

low compression high boost seems to be kinda dumb to me, not to say it doesn't make power, but it seems more efficient to do a higher compression so you won't have to boost as much to make the same power and have more room to grow. Anyway, I fap to this build all the time!

Well yes... But there is the issue... without bleeding off alot of the boost with a cam or a boost controller I'm assuming its going to be hard to put more than 7or 8 PSI into the motor even under "race conditions"... (just a novice guestimate...)
If that is the case he has some pretty large turbos to only produce lets say 10 psi...
Im sure they know y they are running that combo and im curious... Maybe there is something else to it...

What is the reason... I would agree... I would never build a car that ran turbos and had under 9 to 1... simply because of the lack of low end boost (equating to no get up and go off the line)... a roots or twin screw is another monster... but at 9 to 1 you still have quite a bit of "motor only" hp to help you get off the line and you could prolly feed it 5 (maybe more) PSI of boost... (compared to a similar set-up running over 10:1)... and boost air is cooler (or has the ability to be cooled) which allows for more hp without boom...
