What's extremely impressive about this test, as Jason says, is the area under the curve - the 15-20 ft-lb increase over the entire 3000 RPM band. This speaks of serious engineering, with attention paid not just to airflow, but to maximizing finite amplitude wave resonance tuning. You simply can't get those kind of results with a grinder and a flow bench - this takes extensive R & D.

Jason:
Has your organization actually tested a ported LS7 intake manifold to see if it shows gains over a stock GM part? The below quoted post makes it SOUND like you have, but you didn't say so. If, out of professional courtesy, you don't want to name whose work you tested, I understand, but:
HAVE YOU OR HAVE YOU NOT TESTED A PORTED MANIFOLD,and what were the results?

I miss cell 2, had a lot of good memories on that dyno.
These are real numbers everyone. In fact, they are probably a bit conservative. The dyno's at Katech are calibrated to the exact same specs as the GM dyno's. If Katech hasn't seen a gain in porting the LS7 intake, it is real. Unless, like Jason said, someone would be willing to put their manifold and money where there mouth is and send up a manifold and about $800 to Katech so they can crank it up and see what it makes.
Nice gains Jason. Who is turning the ***** on the dyno these days?

Guys,
We have had the manifold tested at Wegner Motorsports as well, I'll post the results below. We have further testing in the works and will post as it is completed. Thanks again for all the interest in the new FAST/RHS LSXR intake manifolds.
For further information, technical questions, and availability, please contact our technical support group at: 1-877-334-8355.

Thank You for your response. I'll be interested in your results. I think you already have a ported manifold belonging to a friend who would probably be interested in the A/B on the motor you are building for him.

I can't wait for this to be tested on a seriously built LS7. Excellent gains throughout the RPM band. Nice job guys on the design of this new LS7 intake!
I'm in after further testing/results.

Guys,
We had the FAST LSXR manifold (LS7 type, pn 146202) tested at SAM (Judson), I'll post the results below. Thanks Judson and SAM! They are planning an A-B track test comparison, which will be featured in GM High Tech Performance magazine. As updates or additional testing become available, i will continue with updates. Thanks again for all the interest in the new FAST/RHS LSXR intake manifolds.

This is Linda's 98 camaro with the 500 cubic inch engine. Cam is Comp 248/254 .646/.646. The heads are cleaned up LS7. Compression is 10.8 This is through a nine inch rear end, 400 turbo, and slicks with 27 degrees of timing. Tthe exhaust is 1 7/8 headers and 3 inch exhaust with magna flow mufflers.
...and with tuning:

i know you guys are katech..... but i have personally done a dyno pull then pulled the stock ls7 manifold and put on a properly ported ls7 intake manifold on the car while it was on the dyno and seen exactly 10 rwhp, and about 8ftlbs, so its worth something to me......... so in my eyes with the proper person porting it they are worth some power

Jason: Why do you feel we got such different results? I know that when racing rules require stock pieces, some teams go through hundreds to get that one perfect piece, like finding 8 connecting rods with the same weight and length (just an example). Is is possible your manifold is one that just came out right, with very little casting flash and mismatches?

I also saw 11 additional rwhp, no other changes, just a ported tb and manifold. Same dyno,independent from the porter, similar conditions.

2. Like Gigapunk said, there is a few horsepower likely in the throttle body. I would guess 4-5hp.
