your ls6 intake is FINE !! 1k more or less for a maximum of 10-20 hp gain & loss in the low end tq curve is just an unfair debate .... IMO go for a NOS system with all the goodies & push that tq to nearly 600 with a 150 wet shot .... if its a daily driver (DON'T GO FAST) UNLESS !! its a 90-92 combo with a cost lower than 600$. yet a 10rwhp isn't worth 600$, dont u think RWHP/RWTQ math for the buck is out to be thought throughly ??

the FAST is a proven product. and it allows for future growth if you want to go to a bigger cam/better heads. and please show me where this loss in low end torque comes from....

bottom line is it takes a lot of money the deeper you go into making hp.

I have seen 1 or 2 sheets showing a loss of 5-10 rwtq BELOW 3k rpms. I didn't experience that personally, but I came from a ls1 intake and did a light port job on the fast before I put it on. Felt better everywhere but above 4k rpms was a "holy ****" experience.

Again, people who have no cllue what they are talking about.....The FAST does not loose any torque!

Ive tested them all on various application from stock to wild, and its almost always even from idle to 3500RPM. After 3500 RPM you will see 10-15hp over an LS6.

thank you for your kind words,
i was talking about the 102mm fast for stock cubes (not worth the money for the hp/tq).... Bigger isn't always better .... for the OP ... please don't use the words of the forum members as a guide ... use our opinions for your research only .... FAST intakes are mostly a good upgrade for a very mild setup .... i don't see much better gains with upgrading only your Intake Combo ..... power adders are your best bang for the buck at this point.

to the OP,
True but do the math your self at this point with a 1200$ budget ..... loss of tq below the 3k RPM or maybe even equal power below 3K RPM .... does your car see above 4K often ??? are you willing to spend 1K more or less for 10-20hp only above 4K ???? I say go FAST if your in it for the looks under your hood go NOS if you really want a big diffrence in your HP/TQ.

Not going to argue you're bang/buck argument but when are you going to care about extra HP except when you are WOT? When are you WOT that you won't be over 4k rpm? If you're racing or driving spirited and you're under 4k much you're doing it wrong.

And for the love of God, nitrous. Nitrous. Nitrous.

yeah believe it or not some of us don't want to spray our cars. also nitrous should not be used as a crutch. skimping on your motor so u have money for nitrous is definitely the wrong way to go about moding your car. you buy the right parts right now so it will potentially save you from replacing it down the road. ex: buy a FAST intake now so later down the road when you want a bigger cam/heads/whatever you wont have to replace that $300 ls6 intake with a $1k FAST. just save up for one now, do it right, do it once, and be done with it. is that really so hard to understand?

Your welcome, and your still wrong. The 102mm works just fine on stock cubed cars and will make 10-15hp even on a stock engine. Throttle Body size of the intake has NOTHING to do with too big or too small in reguards to curves as we are discussing.

I gained 33 rwhp / 27 rwtq with the addition of my properly ported Fast 85 + underdrive pulley. Sorry the graph is so jagged, had a problem with the RPM pickup on the dyno. As you can see I gained power everywhere, and this is with a set of unported 243's (custom valve job and milled to 62 cc 11:1). and a custom bre 224 cam. Oh and the low numbers is from when my car was bolt ons. I gained torque through out the entire curve!

I got a brand new ls6 intake on here awhile back for $280 bucks brand new from a guy that had bought it and sold his car. Great deal and gained me 2 tenths in the 1/4 and 2 mph. The car felt better with it on. I liked the ls6 intake mod more than my LT headers.

when i had the 346, and the ported ls6, it was pretty strong. then, when i got it back with the 92mm snout, and added the NW 92mm tb, it just woke up throughout the entire rpm. the tires would just break loose easily.

I recommend the 102 to everybody, as stated on a stock LS1 the gains won't be earth shattering but they will be there and the more you mod the more it will pay for itself
