FAST 92's have been out to replace the 90's. The base price is slightly more than the 90's.

 

lol why would fast 90s go up in price? just because it was discontinued doesnt make it a collectors item....The 92mm has replaced the 90 just like on2 mentioned ^^^

Is this realistic people, i mean really, you gained 24twhp/19rwtq over the Ls6 intake?? So over a stock intake your saying it gives around 30-35 rwhp/25-30rwtq?

 

i had a LS6 intake in my car and i got the Fast 90/90 ,but i can't tell you how much of a difference it was cuz i got a cam at the same time with some other mods... i say they are worth the money 430RWHP

 

its a large gain over the LS1 intake....

 

Yes....with good heads (making a stock intake a larger restriction) the average gains from my ported gold....I mean plastic...FAST intakes are usually 20-25 RWHP over an LS6 baseline....add 5 more to that if the base manifold is an LS1 or LS2 (the worst performing stock intakes). Big money but big gains (I figure a Mamo ported intake is like a gold brick and a half right?....LOL).

I tested a customers 6.0 litre on an engine dyno awhile back (fitted with AFR 205 heads and a mild hyd. roller cam...228 ish)....with no other changes besides removing the stock LS2 intake and swapping on one of my ported FAST 90's (even stayed with the same BBK cable operated 85 mm TB on both tests....not an optimal TB), we immediatly saw 32 HP gain in peak to peak numbers (40 HP past peak) and 20 more ft/lbs of torque over about 1500 RPM. It was ridiculous honestly and it looked like we did a head swap when you over layed the two dyno curves.

Needless to say I didnt take the ported FAST home with me that day.....LOL
