Begi Intake Manifold
Any results yet? I just read up on cat vs test-pipe dyno stuff and I think I'm going to go another direction. Did Corky or Tim ever discuss the possibility that this intake, in whatever form, will help move more air at lower rpm and get my tater spooled-up sooner?
If I bought up this intake, I wouldn't have to cut my glorious FM hood. Steve@Powercurve and I have an arangement worked out in trade, so I could get it on the dyno quickly.

I don't particularly remember your build thread, but I'd look to the head for better gains in spool. The IM should (hopefully) solve the top end drop off seen with the stocker. I wouldn't know though, its 25 degrees here so my manifold isn't on yet

those rpm #'s are not accurate. It hitting max torque at 4krpm, and 15psi there too. I know it could be better, but I think it may be fast enough. Its "orange gt3rs-fast" on a highway roll in 3rd to redline in 5th. Once I get the new suspension on...it will hopefully "orange gt3rs-corner" too. I've heard that long-runner intakes help add torque down low, but then I look at that dyno and think that I can add more power and torque, but what about the additional heat and stress on the drivetrain.
I don't really know that I want to drive this car at its current power level on the track. You can ask anyone who's ridden, driven, or seen it...this car moves.

...nothing like trading parts for dyno time!

I've moved this to the appropriate thread. I really want to track my progress and thinking there for the next guy who does this.

now, back to the intake plenum discussion.

Steph, do you think it's possible to do something for my 99 that won't give me a CEL? You know the car; 99 S4.
