Fast 90 Intake porting..
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

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.
really? do you know of a link on the boards where this is said? I'm gonna hang onto my unported setup if thats the case!!!

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!

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.
