The graph above represents a mild heads/cam package with the addition of a Stock FAST 90mm intake Vs a Vengeance ported 90mm FAST.

As you can see, the car made 435/402 with the stock LS6 intake. Bolting on a stock out of the box FAST picked up 7rwhp and 5 ftlbs..... We removed the intake, ported the runners/intake and reinstalled the following day. The port work required tuning due to the additional airflow, the #s jumped to 458/426...This is a gain of 23rwhp/24ftlbs over the LS6 and 16rwhp/19ftlbs over the stock FAST.

Please note!! We did not tune for the stock FAST as the Air fuel did not change with the addition of this intake. Tuning was done on the ported intake, only to correct the air fuel.

Can you post the air fuel values for the graphs as well? Was fueling the ONLY thing changed in the tune?

I just dont see a 7 hp gain from a 90mm FAST. Was the LS6 TB a stock one or ported?

Hey Ron!

Looks pretty impressive chief...do you have a graph against RPM's instead of speed you can post? Also, is this the exact same car? Same gears?

Thanks for posting-up.

Damn Ron, can you imagine what my old setup would have made with that combo....

Ron@Vengeance

iTrader: (51)

No Jim, this is a completely different car, one with 3:42s and one with 4:56s... I thought that would keep the comparison fair

If you look at the data file, it shows its the same car, it also shows the stock FAST Vs the ported FAST were done within 1 day. The car was never removed from the dyno.


Josh, your setup would have rocked with the 90mm combo.. Esp a Vengeance ported one Lookin forward to seeing you back in the game.

Indeed. Looking foward to it, and VRD will be doing all my tuning for sure.

price on Vengance racing porting of Fast 90?


I gotta say i'm impressed, not with the hp increase(althought i'll take it~!) but more-so the torque gain. This is what annoys me most with my setup.

I did put down 460rwhp, but laid down a weak 408rwtq with my setup


Ron-would a vengance port job on my Fast 90 produce similiar results?

just curious... is there a reason there wasn't a tune done after the initial fast install? I was under the impression the larger intake with or without porting would have way to much airflow compared to the ls6

As I stated above, the Air Fuel did not change with the install of the STOCK FAST. Some have said it will. Im sure it has alot to do with individual setups.

ah missed that.. must of stopped reading after the "We did not tune for the stock FAST"!

I must say good work guys!!! Those are some stout gains over an already stout intake!when my motor comes apart this winter, I will def send my 90 over to you all!!!

good showing at the Shootout!!! fyi I was in the pewter ws6 on 75 on the way down there!

Awesome numbers Ron! What is your standard prices for porting? I'm looking to get a LT1 intake and throttle body done by someone local if possible.

Nice looking numbers. How much do the ported fast intakes cost Ron? PM me a price if you don't mind.
