will I see any gains from a fast 92/92? I have been looking into buying a fast 92/92 and wondering will I see any or very little gains from a ls6 intake and ported tb. I know they pretty pricey right now but its gonna be a gift. I really like how my car runs but would like this money to go towards making it faster at the track. If all I see is a tenth I might find something else to put it on. My times are in my sig

Yep, definitely double digit gains. Everyone praises the LS6 but pretty much every aftermarket manifold will show gains over it take your pick (BBK, Pro Products, FAST, Weiand etc) Get the FAST

i think best induction combo would be FTP 98mm lid (converts to a 85mm due to the way the neck is designed) stock 85mm maf descreen, slp bellow, with a professional products 85mm tb. all 85mm all sized matched makes for good velocity... fast will make great power but if you are running an ls1 (78mm maf) it would be "chocking" so to speak. all 85mm would be a good combo in my opinion.

You won't be dissapointed with the fast 92 92 . When you get a tune with it cause it definitly throw your air/fuel off a bit Mayby try a speed density tune. Max effort airflow.

Best you keep quiet unless you've actually run the 102 combo.
Those of you using a maf! WHY? Why keep an obstruction in your air intake.
Throw it away and get a mafless tune
OP go with the 92/92 or spend the $$$ on O2

The internal runners of the intake manifold feed the ports and create velocity, etc. The plenum simply needs to be able to feed the runners with enough air, size doesnt matter for port velocity at all.....

I had one installed by Vengeance Racing and tuned by Jeremy Formato on my last built 347 LS1 longblock (w/ LS6 intake). I only got a few rwhp out of it.
I'd say log your MAP kPa at WOT. It should be very close or slightly over 100 throughout the entire pull. If you have an intake restriction you'll see it drop. If it's closer to 95 than 100 then you're losing power but it may not be significant if still in the upper 90's. For your current motor I say stick with your LS6 intake and save the money.
SweetS10V8: Any chance you can get me the details on those LS3/LSXRT intake runners? Such as length, width, height, volume in cc's? Might you have the L/W/H of the plenums also?
