Default How MUCH BOOST will the LS2 intake hold?

Anyone use an LS2 intake for 20psi or more?

What's the most psi that is reported with an LS2 intake?

4 bolt still. No idea on torque. When I actually make a full 867rwhp/25psi pass the car should run 15_ mph.

How much timing? You gotta have some serious cylinder pressure for 4 bolt heads!

I'm running a 348ci with 8:1 compression, that's why the combo is running a lot of boost. I should say once the car makes like a 900rwhp it should be 16x mph, I was kinda sandbagging there which is lame.

PSJ When you ran 9.44 how much boost were you running?? with 8:1 what is the highest boost you run with Pump gas???

Mighty Mouse ran 18-20psi with stock CI LS2 but little heads lifting but I dont know which heads is he running.

Jay Johnson this off topic but there is a very very old vid with Powter Camaro
(with Flame) at the track after 1/8 the T-top ejected is that you??

I am building a 408 with 8.8-1 and I had the machine shop stud everything. My goal is 1k rwhp, hopefully the intakes are good enough to support the boost i will have to run to makr that power.

9.44, I had 20 psi set on the controller but had some issues 2/3 track and the car nosed over.

I was screwing around with 16psi on the street this weekend it was fun. I'm guessing I can do about 15-20 on pump gas but we'll see.
