Victor jr vs LS2 intake
power my goal with this car was to be at least 1000 fwhp, and be able to sink it into the 8's. Like i mentioned this car will now primarily be a 1/4 track car, so i am trying to get the maximum potential out of the setup I am running now.
Fast The only issue with the fast intakes i have personally seen is too much power 
One SC and one twin turbo, both made good steam and did not pop the intake like most say. One was 9psi and one was 14psi.
If the seal is a huge deal, fast sells rebuild seals to go through and check it out.

New intake includes refinements such as enlarged throttle body opening, higher strength polymer manifold materials and improved throttle body sealing flange and o-ring gasket
Forget about inferior knock-offs, the patented LSX™ 92mm Intake Manifold from FAST™ is the only three-piece Gen III composite manifold proven to deliver increased performance without compromising bottom-end drivability or high rpm power. For both street and racing applications, the intake manifold is an easy bolt-on installation for GM Gen III (LS1, -2 & -6) engines and is designed to work with the new FAST™ Big Mouth Throttle Body™. In an effort to improve on the previously successful LSX™ Intake Manifold introduced three years ago, the 92mm manifold has received a host of feedback-driven refinements and a larger throttle opening to match the newly released FAST™ Big Mouth™ 92mm throttle body.
The new FAST™ LSX™ 92mm Intake Manifold maintains the performance gains achieved over stock intake manifolds with no loss in drivability or low rpm torque. While the new FAST™ intake manifold delivers terrific performance right out of the box, it can be ported by the customer for even more flow. As requested by previous LSX™ customers, the new intake features the added benefits of corrosion-free stainless steel assembly bolts, an improved throttle body seal
I realize that is a pretty good number, but just have had doubts with that intake
and elbow combo. People I have said that with Ls6 style intake, I might bring that number up because it would be more velocity... besides with that elbow being cut the way it is i am not sure if i am losing there.. Just looking at it as I have spent so much already that If it is going to benefit me to try a different intake setup, then that is something I might want to look into doing...

I have a bare LS2 intake if you want to borrow it and try it, no fuel rails or anything.
I'm still running my LS2 in my turbo car.
When I had the blower I made 754rwhp with a TH400, 8:1 348ci, LS6 intake, big headers, duals, and 21.5 psi. Went 9.40@143 with 18 psi and 680rwhp.

NASTY98TA Search SpeedRacer or something he is running FAST 90mm Intake
with 402ci AFR 225 F1A 16PSI made 914rwhp 800+rwtq with no problem what so ever he also ran 18psi
now he is running the same setup but with 427ci PM him.
Good luck.

I just started tuning my friends car 427 F1R car with the GMPP intake and Nitrous Dave modded elbow. At 5000 rpm it made 874 rwhp and 780 rwtq. We then pulled my graph with the 402/F1R/LS6 and under the curve the difference are as much as 100 hp and 100 foot/lbs of torque until around 5000 rpm where it catches up.
That was enough for me to get him to pull his intake and stick on the LS6, no matter how cool the carb intake looks. Now we just gotta sort out the fueling.

Very useful info, I am getting ready to put a intake back on the car, so I am even debating going back to a LS6.
