how did you geta slp smooth bellow over a 90 or 92mm tb?[/QUOTE]
It wasn't easy, but it fits tight and I do not need to run a clamp as you can see, looks cleaner IMO.
To make it fit, I sanded the sharp edges on the tb snout to keep the tb from "biting" the bellow. Other then that I used a screwdriver to help force it over the tb from the inside of the bellow. It has been this way for 1 year now and fits tight, doesn't pop off, and has not ripped at all. Also I have poly mounts, if i had stock motor mounts I'm sure the twisting from the motor would cause issues.

In a perfect world I would have provided results with a 90mm FAST as well. Unfortunately being a C6 our customer wasnt interested in cutting his firewall for testing of an intake he was not going to keep on the car.
That being said, there are literally thousands of A/B comparisons of the FAST 90/92 over LS1/LS6/LS2 intakes all over the net. I have never seen a FAST produce 40rwhp like we did today with our ported 102.....

frist off the 102 fast intake is BIG very BIG with no room at all on a C5 corvette or f-body cowl. one can just look at the 102 and see that it will make more power! this is a big heavy intake around 20lb with a fast 90
around 14lb and is very well built, but it's BIGGGGGGGG!!!!

Im going to be intersted to see the results from a LS6 or 90/92mm intake to 102mm intake on a stock cube LS1 (346) with only bolt-ons and or cam-only seeing as the 90/92's are not going to be made anymore and many people with bigger cams saw gains from the 90/92 setups but will the 102mm be too laggy down low for the switch?.. this is what I want to see. ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
Many Ls1tech'rs have only bolt-ons or just a cam but want more airflow from a nice intake, esp if they want to shoot some juice thru it, the extra incoming air will help.

yeah for sure! im excited for more results! yeah yeah, its not super impressive over a ported 92...but soon were not going to have a choice, unless someone makes the street warrior! LMAO!
im thinking these would do good on a 346 h/c. ive read pat g's stuff on intakes and how they cut off airflow around 260cfm (ls6) and around 275-280 (fast 90/92). people are throwing heads on stock ci that flow 310-330...pretty decent numbers, and they do good, but in the end are choked by the intake....not a ton, and yes with a fast...so im sure this thing out-flows a 92, but by how much, and how would those h/c/i combos work now??? just thinking here...

Ive still got the the LS6 Intake and my PRC heads are suposed to flow lil over 300cfm....
I have not had the car on the dyno yet but will likely want to upgrade the intake in the future just seiing what FAST set-up would be best suited for my set-up.
The 102 may be overkill? esp with 102 mm tb? Ive currently got a modified 85mm LS6 with 85mm TB but again no numbers yet but intial tuning did show a restriction in the the intake system

The only pertinent tests are directly against the 92/92 combo on stock cubes and then on something big that needs to breath. We all know what these setups do against stock intakes. I'm guessing this is not a worthwhile upgrade for someone that already has a 92/92 setup. I'm pretty sure many vendors have already tested and found minimal if any gains by upgrading from the 90/90 or 92/92 FAST setups. I would upgrade in a heartbeat to the 102/102 even if it made the same power but carried the rpm's 200-300 higher than my current FAST 92/92. My motor runs out of air very quickly above 6400.

I'd like to see power carry past 6400 as well. It would be cool to see it peak and hold all the way to the rev limiter. Holding onto 30 rwhp up top is like gaining 30 peak, depending on how you look at it.

I was thinking about going with a Super Victor but was told that my 254/262 650/650 112 lsa cam wasn't the best match for that intake. I really don't want to have to change cams for an intake swap.

I thought about an EFI Victor Jr b/c it flowed air to 7200rpms compared to FAST 90/92s 6400rpms. But the FAST provided over 40lbs-ft tq more in the midrange compared to Victor Jr.

If I need to swap cams for a single plane I may as well spend the $$$ and go with a Victor or Cary's intake and go solid roller.

I have a 5000 stall and don't care that much about midrange. I was just hoping this new FAST 102 had something to offer above the 92. 7200 is about as high as I want to spin it with my current oiling system.
