all i seem to see is good dyno numbers. high numbers are fun but how many of you have actual track results of your fast intakes in comparable weather. thats where it counts! the difference between your ls6 intake in +2000 DA and your fast intake at -1000DA is pretty much void haha.

lets try and get intake only swaps...as in the only change between runs was the intake and throttle body. make sure and say what intake you had before the swap and list out your other major mods if you feel like it.

you guys spend that much on these things and dont want to brag about them? lets hear it

so these things are only good for sweet dyno times?

everyone post up your track losses then i guess

could people also put there track time losses from putting a vic jr on too.

I had zero track gain from the FAST 90 over an LS6. It was expected though.

i figured there would be more posts about this...so im assuming that the fast intake manifolds are only good for cool dyno numbers?

honestly, most people dont so back to back testing with the 92/92. dyno testing makes more sense. but you can see the gains in the midrange torque and a decent amount of power in the upper rpm's. it just makes sense. i dont see why it WOULDNT pick up. esp. in a cam only or HCI car.

from what i have seen i would not get one until heads were put on the car. i ended up getting a ported one when vengenance had the best deal i have seen to date. however, i do have full bolt on's, cam and ported heads.

You dont read much then. Everyone except one dyno grpah ive seen has shown the FAST to pick up power and torque everywhere.

Which also means faster times, period. People dont take thier intakes to the track and swap them around for fun.

i didn't say that you were not allowed to buy a fast intake. i gave my opinion. i was taking everything into account. you need to buy the intake and a throttle body and have it installed. i haven't seen much more than 10 additional horsepower with a fast intake while running stock heads. i am not saying it isn't possible but from the most part that is what i have seen. the cost isn't worth the benefit in a lot of situations in my honest opinion.

I gained 21rwhp and picked up power and toque at EVERY point in the curve. I have a 90mm DBW throttle body so both intakes had the same advantage.

I ran my truck on the dyno, swapped the intake and ran it again. No tuning, stock heads, stock cam, stock exhaust manifolds, stock everything!

i will let you know both dyno gain(same dyno) and track results with DA kept into consideration on my cam only setup here in the next week...

Sweet, you have to remember most of the guys in here are gen III, not exactly apples to apples. I think you have a 6.0 liter, probably 243 heads, and had an LS2 intake. Switching from the LS2 to the fast intake took you from 300 to 320rwhp.

On a 346ci LS1 with crap stock heads the results are usually different than yours. An LS1 with a good sized cam will see good gains with a fast, and adding good flowing heads make the gain from the fast even better.

The LS6 is a great intake. I would never spend the money on a FAST unless I had at least a cam. The FAST makes alot of power in the upper rpms where the stock cam and heads start to top out. It will improve track times but I too am interested in how much. Since I installed my cam, heads, headers, intake all at once I cant really judge how much teh FAST did for me.

my car is noticeably stronger all through the power band, especially above 4k

never ran it before the swap though...but I went from dynoing 325hp to running the mph of a car with 350-360 hp (cant be exact since I haven't weighed the car, but I do have a cam

I know this is a old post but i've noticed this as well. Everyone that post dyno gains never say anything about track gains. Now who would spend over $1,000 for intake & TB and another $250 for porting and not take the car to the track? They wouldn't. This is exactly why i've always been leery about spending that much money since i don't really care about dyno results since i don't drive on a dyno. It's more important what it can gain at the track. The average dyno gain is between 15rwhp to 20rwhp and about 15rwtq and less on smaller head/cam setups. That's only about 1 or 2 tenths in the 1/4 mile. Not a hell of a lot of gain for $1400+.

21hp GREAT...so what did you gain at the track??? So you never took your truck to the track before the intake swap? Come on dude, be for real.

BlackNiteWS6

iTrader: (2)

So you did all that work to a Chevelle and you never took it to the track before and after the intake install? " noticeably stronger" isn't a true test. And "dynoing 325hp to running the mph of a car with 350hp-360hp" doesn't even make sense. So what mph did you run? What ET did you run?

I went 10.8 at 126 mph with a fast 78. I'd imagine a 92 would have helped a little in the mph.
