Going to try again FAST 92mm question Lets say you have a high compression (11.5+ to 1) H/C car. High DCR 8.6 neighborhood. Now you add a (from what I've been reading) 92mm FAST which can be ported to 95mm and matched to a 95mm T/b no one thinks that real gains can be had ??? Maybe this new 92 FAST is only for bigger cubic inch motors. Just fishing for opinions with a little more information this time.

Care to add something constructive or just bash. Please backup your opinions. I have been in touch with several sponsors and it is their opinion that power can be had when bolted on to an aggressive 346 setup or more CI's.

I can't wait until someone does a back to back comparison of a ported 90 combo vs a 95 combo. From what I am being told the new 92mm FAST can be ported to 95mm and matched nicely to a 95mm t/b and potentially yield some modest gains in the upper portion of the powerband. If you have proof to refute this hypothesis please post up. All comments welcome as long as you can back them up. THANKS

sounds like you got your answer. to back up my opinion: i think its stupid to post this poll when it had already been done and failed.

This is what I've been waiting to see. Thanks in advance
I would like to see a back to back dyno runs. I think us stock guys would see no difference because there are other restrictions in our intake systems that limit flow to less than what a 90mm TB can flow anyway.
If you plan on retaining an O-ring to seal your TB thats not going to happen.
There is a reason Comp (FAST) stopped at 92mm....thats what they felt left enough material to properly support the O-ring seal...as this pic below clearly shows its quite thin right out of the box and if you attempted to open it to 95mm, you would have to completely remove the inner O-ring support to accomplish this. The O-Ring would be useless at that point.
A pic tells a thousand words....
As I mentioned in the other Allngn post.....there are four reasons to buy the 92mm FAST....more power than a 90mm FAST isnt one of them.

I would like to know the trick of exactly how we port the 92 to 95mm....

Thanks for the good info as always Tony. The pic is worth a thousand words. No harm in testing the two back to back and erasing all doubt.
The biggest reasons that I am interested in the new FAST 92 is that I am considering more cubic inches on my next motor. Also considering a deal that is in my lap and a sale that erases the difference in cost why not test the theory. Nothing has been finalized yet, but for the minimal cost involved and considering I'd have my intake and tb for my next motor it makes sense to me.
Hmmm, Rev Extremes TB must not be 95mm because I have ported 3 of the FAST 92mms with their 95mm TB and RETAINED the stock O ring with NO issues at all.
Not starting a flamefest here, just stating my experience.
Also, I think its funny as hell everyone on the net always says the FAST is running out of steam etc etc and then something comes along that a better design and everyone says it wont do a thing... We all know on your AVERAGE combo the 92 will show no gains over the 90, BUT on something like the combo in question I feel there is a slight gain to be had.
FWIW, We will be doing back to back testing in house in about 2 weeks on a LSX 454 using a FAST 90mm Combo and a 92mm manifold opened up for a Rev 100mm TB (not using the O Ring for sealing)
