Default ls6 or fast

ok so i have some extra money coming to me on this deployment and was wondering. Should i just settle with an ls6 intake or should i just put up the cash and get a fast? just need to know how much better the fast is over the ls6 and would be for my future ls6 heads and 228r cam?

F.A.S.T is 5-10 HP over the LS6 and more so with heads and cam. If you have the cash, get the F.A.S.T.

I've been debating buying a fast so I can put my LS6 intake on my 89.
you'll need a tb, fuel rails, and either grind your water pump our get a LS2 pump

What are your goals? Is 5-10rwhp worth $800 to you? If you're looking for max effort (which by the looks of your cam, you aren't) then go with the fast. Otherwise save your money and put it towards the heads/cam

You can get a ported LS6 intake for $499 and a p&p LS1/6 throttle body for $129 w/$40 core from B.E.R. Claims they flow right with an out-of-the-box FAST 90. If they really do or not, well don't know from experience. But B.E.R. has told me they will give a 100% money back guarantee if I'm not completely satisfied. So who knows.

Is a FAST intake worth the extra money? On a nearly stock (stock heads & cam) LS1, I say hell no, not a chance. But with big heads and cam, comes more gains from the bigger intake, so then you're getting more horsepower per dollar.

I have used both a LS6 and a Ported 90/90. SOld the 90/90 for extra cash and the car picked up bottom end and mid range power.

You needs heads and compression to take full advantage but remember that FAST do max stall out if you put large enough cyl heads on the car.

When I first sold the LS6 (my stocker) to a friend, he gained 70 rwhp over stock c5 (1999, so read LS1 intake), and MS3 cam 6 speed car. Since it was so choked. So having a good intake helps, like said how much money do you have to spend.

The extra carsh was going to be about 800. But after reading r6s thred i think im going to go through B.E.R. and get one of there ported ls6 intakes seems like a good deal

I have never seen a ls6 intake from anyone flow with a Fast intake, even the 90mm TPIS ls6.

If you are going to save the $$$ and not get a Fast, get a used ls6 and be done. Port the stock tb or get a 85mm tb. No sense dicking around with a pricier intake claiming gains no one has been able to prove in all the years the ls6 intake has been being made.

Let us know how you like the ported ls6 intake.
im still running a stock ls6 on a decent cam, full exhaust...even putting heads on soon. Then, the ls6 will finally be the choking point. Def. save the money and go ls6.

I would try and find a used Fast 90/90 setup and a set of Ford green top injectors (42#). My car picked up an additional 27 RWHP going from the LS6 to the Fast 90/90 and thats it was definately worth it to me. You get to reuse your fuel rails and don't have to worry about the water pump hitting.

Good luck finding a 90/90 setup for less than a 102 setup. Too many people think a 102 is too big for a 346, driving the price of used 90's up.

And too many people don't know what they're talking about, and/or just believe all the assumed BS they read on internet forums. And don't pay enough attention to actual real results and facts.

Having owned a 102 and a ls6, their was a big gain in top end and almost zero loss down bottom with the 102.

People are dumb, like it has been stated thousands of times. A fast is for someone who wants everybody of HP they can get, ls6 is a budget friendly intake worth around 5-10 HP over the shitty ls1 intake. A 102 is not to big for a stock ls1, it has been proven time an time again.

You are going to waist your money on a ported ls6, which is worth 5hp at most, they can't be ported out like a fast. Shitbjust grab a piece of 300 sand paper and go at it, that's all they do...it's very difficult to port match when you can't see where it needs to be taken out. Your going to blow $500 on a ls6? Why not spend a few hundred more and get a better intake?

**** theirs a couple 102's in the classifieds right now brand new for around $750

For the same money as a fast you could have an ls6 intake plus a couple other bolt ons, a fast is best suited for big cubes or a serious h/c car...good luck man and thanks for your service!
