Im gana keep it on 8psi to be safe. I also have right now a ls6 manifold with ported throtle body I was thinking of going with the fast 90/90 combo would it really make a diffrence with the blower on?

 

Your LS6 manifold is pleanty good enough man That topic has been beat to death in here to. A little searching would net you tons of threads on that debate. Altho I'm sure even the advocates for bigger manifolds would even agree that at your level, you would be better off investing the money into things that won't really agree with your new power such as your trans, driveshaft, and rear end.

 

15-16 psi, my car isn't exactly a dyno queen though. Stalled A4 w/triple disc converter, 3" steel DS, 12 bolt w/true track, and 12" wide wheels

 

Mr. President made a little over 600rwhp on a stock bottom end with 9lbs.

 

Stick with the LS6 I am still running it and making over 770hp. By brother is still running stock bottom end and a LS6 making 640 on 8 or 9 pounds with a d1sc so you are plenty fine

 

Gotcha, I just don't recall you posting about your boost levels and I was always curious. Still good numbers, how much timing are you running?

 

What kind of cam do you have?

 

ok last question I still have the stock maf, do I have to get a diffrent one or will the stock one hold just fine?

 

If you can upgrade your pistons, valve springs and pushrods seems that you would be good for boost (to an extent) I would just do that and have the car running safely.

 

Its cheaper and easier to upgrade before something breaks. If cost is an issue for you, as it is for me, be patient. Something better might come along while you keep researching.

 

Those pulls were at 16*, 93+Meth. Its been upped to 18* and has taken it on the street, just haven't got it back on the rollers. It is under the knife again and I'm hoping to pick up a little more power so we'll see by about Wed. next week.

 

Nice, I'm trying to sell this MAF Snow Performance 2 Stage kit that I have so I can actually get the MAP version so I can run meth and up my timing. I'm only running 14* with 93. Hell, I can't hook up now, that extra power wouldn't help that much either. Let me know what you end up making

 

Will do man! The car is worthless on the street sub 50MPH, it simply doesn't hook. Cut's 1.4 60's on DR's at the track tho, not bad for 3966lbs!

 

Hell No that isn't bad that is hella good!!!!

 

Hopefully thats what I'll be cutting when I get my new tires. I was cutting mid 1.5's n/a and the best I could cut with some bald qtp's was a 1.65. I'm probably right around your weight, we have some PIGS
