FAST intakes still sell pretty high most of the time. I just got luck and snagged a fast 90 for $400 from a buddy. The LS6 has pretty decent runner volume for a 346ci engine, but the biggest issue is that 78mm inlet. I've seen several people make claims that the tpis 90mm ls6 intakes rival the fast 90 (non ported).

A couple weeks ago I was helping a buddy look for Fast intakes and found several in the $500-600 range in the classifieds here. Right now there is one that was cracked and repaired for $400 and another for an intake with 90mm tb for $900. I would take either of those over sending an intake off for the snout conversion.
Does TPIS even still do the conversion? I can't say I've seen any results from one of their intakes in several years and the ones I found back when I was deciding between buying a used Fast or trying the TPIS weren't all that impressive. People claimed it was as good as a Fast but I never found proof that was true. There was one magazine article floating around and that was about it.

The Fast 78 will outperform a LS6 intake. The inlet isn't the primary factor.

I know this thread is old as F, but I have a 90' Camaro drag car with a STOCK LS1 long block. I have ran it with a LS1 and a LS6 intake and gained .25 sec. ET. I will probably be installing the 102 I have for some real world racing numbers. If someone has a TPIS intake they want to prove is as good, I would be happy to try it out for them. While I bet it will out perform a stock LS6 intake, I am sceptical about it besting the FAST.

not what i was expecting
as for cost comparison (cost new from TSP):
92mm FAST Intake Manifold with PTM 92mm Throttle Body = $1100
subtract $300-350 for the ls6 intake
subtract $50-100 for the stock throttle body (depending on if its ported)
total for a FAST setup is $650-750 out of pocket
cost for TPIS modified manifold is $350
plus the cost of the 90mm TB $350-400
minus the $50-100 for the stock TB
total for the modified setup is $600-700 out of pocket.
i'll chose the FAST...especially since it has the option to port

I gained 4 tenths and 4 mph going with a ported FAST 102 etc over LS6 stuff after tuning. If you are going to spin it past 6500 then the MSD is the way to go. LS6 is too small on a decent 346. The TPIS LS6 should not even be considered these days in my opinion. The cost of intakes are high and a good throttle body price is insane. But that feeling goes out the door when you run 11.7s with bolt ons in a stock looking car and 10s with heads cam all on 93 octane. The cost of this hobby at times sucks for sure...

Full interior, stock 10 bolt with stock 3.23's. I had a Vig.3600 though, plus a home ported set of my stock 241's, and i ran the Comp. 216/220 114lsa. For that setup i had, there's NO WAY a FAST wouldn't be worth the cost for such a small gain. With my little 216/220 cam i wasn't even putting a strain on my LS6 intake. So spending $900 for an intake and $300 to $400 to have it ported. That's $1,200+ and that's not counting the TB. Now on a lighter car with big heads/big cam and gears then yes i can see the FAST giving gains, but unless i'm bracket racing, i would still have to ask myself if the FAST would be worth it. Over $1,500 for a few tenths isn't worth it to me. Plus the FAST wouldn't do you any favors on a everyday street car like my WS6 was. Unless i wanted to dyno race it. I saw more guys on here say they got 20hp on the dyno, yet the car was a turd at the track. I know what you mean about the MSD intake. I like that the runners are straight, cause as you know air doesn't like to make turns. The early FAST intakes the top of the runners made a 180 degree turn, that was where the opening was. And the FAST runners are the same as the LS6...they are both 11 inches. And the LS6 has a OK plenum volume. But it's BS when people say the TPIS LS6 intake doesn't work. That's BS. People use the excuse that the TB means nothing...haha Well if that was the case then why did FAST start with a 78mm TB, then go to a 90mm TB, then a 92mm TB, then finnally a 102mm opening? If TB opening doesn't mean nothing then why would FAST keep upping their intakes. So thats 100% proof that the 90mm opening on an LS6 intake works. The LS6 has 11 inch runners that flow very good, the plenum is a good design, so it's only the TB opening that was holding it back. And if TB openings didn't mean **** then why was everyone porting their TB's or running 78mm TB's? LOL.

Trying to explain that the 90mm option has great gains is like trying to rope the wind. Everyone is always right about every combonation and no one else knows ****. There are plenty of threads proving the 90mm TPIS intake flat out performs. It may not outperform any Fast in certain applications but will in some. I have an LS6 intake with the snout busted off. Guess how I'm gonna have it repaired? LOL

HaHa i know what you mean. My full weight WS6 ran a best at Atco at a 11.78@117mph. Still used my stock front rims/tires. No front sway bar removed.

I know this thread is old. But i laugh at people that justify the cost of a FAST by selling their stock LS6 intake and TB. First of all, the FAST 92mm is over $900, now porting it is another $300 minimum. And the TB for $450. Thats a total of $1650!!!! No one is going to pay over $350 for the intake and maybe $100 to $150 for a stock TB. So thats $500 and that's on the high side. So subtract $500 from $1600.....you're still in the hole for $1000. So i guess gaining maybe 15rwhp justifies a $1600 intake setup? Wow must be nice. But it's funny i still don't see guys posting their times at the track to see how lower their E.T.'s got from that $900 intake.
