I know that the Weiand intake is coming out soon but I want to see what others will be gaining over the FAST "if any" before I get one.

I wanted to know for those that had gone from the LS6 intake to the FAST 90/90 setup, what were the power gains?

15 - 25 RWHP gain seem like a good deal.

 

Anyone TTT

 

me so far, i've only gone from ls1 to ls6 and i only gained 7 rwhp and nearly 10tq

 

It truly depends on the supporting mods and the tune..... I've seen anywhere from 20-45hp on dyno charts.

 

Im waiting to install my LS6 and if I get 7rwhp and 10rwtq ill be happy with that

 

I Think U Should Of Just Got A Fast Intake Wei. Doesnt Really Do To Much Over The Stock One Maybe 5-7

 

I think hes referring to the new wei comming out??

 

Hey just put one on my car tuesday and just ran tonite. I have alot of passes on my car and know it very well so i think i can be pretty accurate on whether or not i gained anything. Well i ran a few 12.40s right off the street and got faster as the night went on 12.38 12.34 and a 12.26 all at 109+ mph with my 60 fts. being within a few hundreths 1.77 to 1.71. Last time i ran the car was last dec in frigid air and ran those numbers so all in all with the air not being anywhere as good as dec i would say that i definatley picked up a solid tenth and a good 1 mph maybe a little more. I am pleased and a little surprised of the gains so it is a gooooood mod to do to 98-00 cars. and i dont have headers yet, who knows could be more of a gain with more mods.

 

which intake do you have dadsz28?

 

ls6...

 

Yea i'm also looking for the difference between ls6 and the 90/90 with decent cam and supporting boltons I seen some post like 30 and some like 15. I don't 15 RWHP is worth the 1400 dollars. But 30 is more tempting.

 

"I don't 15 RWHP is worth the 1400 dollars" the 15 doesn't cost 1400 unless you already have an LS6.

 

I picked up .3 and 3 mph in the quarter with a 90/90 on 98 stock valvetrain motor.

 

I gained 28rwhp and 20rwtq with a FAST92MM over the LS6

 

Detox, is that on a stock cam, and heads? I am looking at a fast intake but i don't know if it would be worth it. If i could get a solid 15whp i would be happy. Do you have stock cubic inch block? Did you lose hp down low? Just trying to get an idea of what gains i will get from going to a fast over my LS6

 

Damn, those are good ETs. I can't wait to get back to the track to see what gains I have from LS6 intake | 28.8lb injectors. Hopefully to see low 12s to flat 12s w/ MT ET streets also. My 12.6 run was on 18s | street tires.

 

Aftermarket cam, stock heads for now, stock cubes. I didn't lose anything.

 

Thanx Bene, yea my car runs really well and i was impressed with the gains from the ls6 intake and slightly bigger injectors. I noticed it pulled harder mid range and up top, definitely a worthwhile mod. Good luck and let us know the results.

 

Detox what are the exact specs on your cam, and how much hp did you put down with the LS6, and what were your finally numbers on the dyno with the new Fast 92? The only reason i am asking is casue i am trying to see if would be worth it to upgrade to the new fast intake.

 

Someone on here did a cam swap and had an LS6 intake to begin with. Also had full boltons. They installed a Fast 90 and gained 10 rwhp and didnt gain any torque. Some food for thought
