Fast Vs Typhoon Manifold Well I've been debating this for a long time now and just can't justify it. I have a heads cam 6.0 GTO and I can't pick what is needed.
Car is an ls1 car and I don't feel the extra work needed for the 102 will benefit me dollar to dollar. The Fast 92 vs the typhoon 96 is the argument I am having. Dollar to dollar and part to part I can't see the fast having a 400 dollar price advantage.
Car has a hand ported ls6 so I'm just looking to squeeze the extra 10-15 horsepower out of it.
What are y'all thoughts on this. What would you do. I know the differences in both manifolds but I just can't see the better fast manifold being worth the extra money for little gains

Would the Typhoon have any benefit over your ported LS6. I don't know how extreme your H/C is but the fast is going to make a difference. You will also get a few dollars for your LS6 intake.
You will also have to tune again to maximize your combo.

I need a retune so I figured I would do that all at once. The heads are afr ported 215s and a TR 236/242
See that's what I like to hear. If it won't make a difference why do it. Fast I guess is still up top

I got 20rwhp out of my ported 92/92 when I already had H/C. I put on a FTP lid, GM 90mm MAF and 4" bellows at the same time. If I could do it again i would have gone 102, not much difference in peak power, maybe 5hp or so. But from the graphs i have seen the hole curve is better. Don't know much about the typhoon.

I have not ruled the 102 out but its just the cost of buying everything new seems like it will add up to more I'm than I want to Pony out on it.
The 102 is awesome the curve and flow and fact that it will be the last manifold I buy make it amazing but the price is just a little high right now

Made 460/420 on a stock FAST 92/NW92 combo... Ported would have been more. I'd go with the Fast 92 and not look back.
All the Typhoon is, is a cast version of the LS6. and with a TB opening they made larger.
The Fast makes it's power in the RUNNER design, not how big the TB opening is.

I think the 92 is $100 more than the 102 but you'll need a rail kit ~$200 and I believe injector extensions which aren't much. So I don't really think the difference is that much but I could be missing something.

What about the 102 Truck manifold? I know it requires some finagling to fit but wouldn't that be the best? There's a thread someone on here where they discussed it. It definitely looked odd in the engine bay for how big it is but there was a considerable difference in power.

Yes the truck lsxrt is superior the whole rpm range up due to it's design. It's pretty much a cross ram intake in a big ugly bread box. There are older threads & pics of it here, yes you do cut the cowl area out of a f-body to fit it.

OP, you'll need to determine of the HP/TQ difference between the FAST 102 and the FAST 92 is going to be worth the extra money it will cost to do the FAST 102 setup.
You'll want at least 36's (ford red tops.) I'd go 42's myself. Pontiac supercharged GTP injectors are 42# at our 58psi fuel pressure. At my power in my sig for the Camaro I was at 77% duty cycle, which is pretty much ideal.
