FAST 92/92 vs LS6 on an SI car ? just wondering if anyone has results with this back to back....any loss in low end, and how much gain across the board ?....any track results also ? ....thinking about picking one of these up and running it on my car while its stock internal just to prepare for when i put a nice cam in it...if it gave me 10rwhp id be very happy, also has some port work done to it...thanks

From what most ppl say the FAST setup is ONLY good when you have both heads and cam.
Even most cam only cars dont gain that much at all going to a FAST from a ls6. Some ppl even lose power! Most ppl opinion on the FAST is that its not worth the price at all unless its on a head and cam car and that its ported also.
Its seems to be common also that you will lose power down low but will make more power up top but thats not always the case as some gain power everywhere even if its not ported but im assuming thats on a head and cam car. If it has a good port gains will be everywhere and much more noticeable.

You will pick power up, especially 5800+ Rpms which I am sure the OP is spinning to.

People one a tight budget don't think it is worth it. People that would love to spend 1000$ on a intake/TB setup (or any mod) and knock off .1+ and 2_mph think it is an awesome deal.

False.. The VAST majority of cars pick up power throughout the entire power band, it is rare for a car to lose anything down low from the swap.
If it has a good port gains will be everywhere and much more noticeable.
If you want more top end, get a 90/92. If you want if to help you more on the bottom end, 102.
The runners are different.. From what I have seen (and on my car), the 102 gives more of a TQ increase and the 90/92 gives more of a HP increase. Of course difference H/C (or lack of) is going to show different results also.

False.. He is going for some quick SI times, not average joe that doesn't think 10Rwhp is worth 400$ or the like.

I havent seen a FAST go for $400.
False.. VERY few cars don't pick up a considerable amount of power (10+) switching to a FAST and a retune (granted same dyno/car running properly/etc). I have never seen anyone lose power and the result being the intake.
There was a thread on here that someone created and i believe they put it on a bolt on car and lost power same dyno also.
False, port work is only worth a small gain.. However, for the price, it is kind of dumb not to get it ported.

From the research ive seen ported ones gain a considerable amount over stock ones especially if ported by Tony mamo.

Once again from all the posts and threads ive been seeing on here and corvette forums plenty of ppl lose power down low UNLESS its on a head and cam car. Not saying all ppl but there quite a few.

400$ over an ls6 will get you a FAST setup if you search. Worth it in my opinion.
I would be interested in seeing it. It makes no sense because they designed that to work with stock cube ls1s from bolt ons to full H/C.
Tony Mamo is an exception. Your average ported FAST will net you about an extra 5-10Rwhp max.
I would like to see these threads where people lose power, down low/mid range/top end/etc.

Lots of internet hearsay with no facts around here.. how about someone posts some documentation to back these opinions.
Btw I have a fast 78, seems to make a lot of power for an ls6 setup, considering bolt on ls6's generally make between 375 and 390whp corrected on the dyno I was on.

All true statements right here. You will not lose power, it just depends on whether you think the gains are worth it for the money.

I have an LS6 now with stock TB and stock MAF with a cam only engine...The gains from the LS6 intake alone were dramaticly high...how about with a bigger TB and Intake??? I dnt know..i was wondering about the same setup..Which is gonna give the most acceleration>>> or if anything what are your personal opinions for a Intake and TB combo...>?
