no dyno tests yet. the ginney pig is kinda off?????

we may do it on my car in a week or 2 though.



all i can honestly say is that people charging $200+ to "port" a FAST intake are a RIP OFF! i have ported a few myself, messed one up testing, and seen some ported by the top dogs on here & there is not 5 hp/tq between mine/theres/anyone elses to be had.

i figure i will get hammered on that one but i mean really, do you think your gonna gain 10-20+ by porting a $800 custom intake? trust me i've messed one up by porting in a certain area that "if possible to improve the design & flow" it would have. it didn't! i think its just off the wall to spend $200, $300, $400, $500+ to have a intake ported when its near impossible to gain more then 1-5hp/tq from. hell even if you do a 1/2ass job yourself that costs you 30min & 20 bucks you can get 1-3hp out of

Maybe it's more about adding then removing, I don't understand why they built it that way in the first place...

if they can give me 10-20RWHP on MY TUNERS DYNO on the same day from an out of the box FAST intake i will pay any amount they want! my 370 should be easy money if its true because its got a hell of a cam & it spins to about 7200 so any gain in flow should help a good bit. around 500rwhp also.

that goes for anyone that "ports" them also

Last I heard, Mamo was admitting that the porting is worth 1-2hp. Basically told my buddy it was really only worth it if your car makes like 498 on a dyno, and you want to claim a 500hp car.

like i said, its not gonna happen.


why do you think this "test" has never been done in the open by any of the porters? i'm not trying to bash any of the venders on this site. i just think it is horrible to take hundreads of dollars from people and make them feel good about almost nothing.

Damn, imagine that I'm wrong ...not a victor but close enough for comparison, fast has alot more horsepower/torque under the curve and only sacrifices ~10 hp or so up top to 7000rpms!

Is this posted somewhere? If so Im sure a lot of people including myself would like to see it. I've talked to him about porting a single plane manifold and he never mentioned anything about such a low gain for the money. Maybe Tony could chime in and clear this up. Sometimes things get misunderstood when taken out of context.

This was from another thread:

https://ls1tech.com/forums/generation-iii-internal-engine/634871-fast-90-90-mild-h-c-set-up.html

Originally Posted by Tony Mamo @ AFR
I recently helped a customer with a bonestock LS1 shortblock that races in the SI classes (stock internals). I ported a FAST 90 for him with a caveat being I couldn't promise him the same returns most people get from my set-up (20-25 is typical). He didnt care and would have been happy to pick up five as it seems this class is fairly competitive. Long story short is he picked up 12 RWHP peak to peak but over 20 HP past peak where the stock intake couldn't keep up. He lost nothing down low....saw gains everywhere.

Dave....if your out there maybe you can chime in. Alot of people claim a FAST is a waste of money on a stock displacement engine (even with better flowing aftermarket heads) and I couldnt disagree more. Even an extremely mild combo can benefit from the extra airflow.

Tony
