12lbs is just fine, up the boost.

 

I am running about 10-1 comp, not using meth, also would like to keep the motor for a while

how much power did you put to the wheels?

 

Duno never hit the rollers.. I would think 500..

"east of 1000 HP"

 

Sounds like you're at the limit already then. I thought about trying a vic jr on my truck. If the theory holds true using shorter runners to make more top end power, it will suit a pro charger well if you are going to spin the motor more. I would personally save the money, get the truck to hook up and make some full passes as it sits, then figure out how much more you need.

 

I see where your coming from.. IF and thats a big word at this point, I could hook this thing, I feel that low-mid 11's are not far off.. Again last time out was no traction and 5psi..Now I 9 psi after I fixed the belt prob. I guess I will wait till I get retuned, slicks to see where I am at.. I know this set up has it in it. I just wanted to get a answer, even if i wait to do it..

presonally id go with the tbss intake....ya ya ya i know,but there's a hand full of tbss guys still runnin the stock intake runnin 10's and 11's

 

I would read up on tech like suggested. The only thing I would be afraid of would be giving up too much torque where you often run on the street. If you are going for peak power and the best track times the vic jr might work better for you. I wish I had firsthand experience with one on my truck to tell you but I didn't get a chance to try it.

 

i could be totally wrong but......if you are already putting 9psi into an engine that has a certain amount of air in the cylinders that you are putting in, than how could you flow any more air to the cylinders than what is flowing to them now with an intake. isnt 9psi on one intake going to be 9psi on another. Now if you change how much air is flowing in or out of the engine, i think that might be where you should focus your gain on.
