So my FAST intake is shot and I need a new one. I have stock 346 boosted with a D1SC at 10 # for now. I have a forged 347 going in later for more boost, I don't think it will go above 15-16#'s due to my altitude. So the question is which intake will net me the most power? The FAST 90/92 or an aluminium one? All opinions welcome. Thanx

 

allum will heat soak even more so cause you are supercharged i would go with the fast

 

how did your fast get shot?

 

fast 92/92

 

It had been leaking a bit so I tightend the bolts some more, everything was fine til it got down -10 for a week or so and it cracked in few spots. One inside so it leaks real bad and three in the mounting bolt holes.

 

At this particular time nothing short of a sheetmetal intake makes FAST power so it gets my vote. I'd go ahead and port too so you get it all. It's a worthwhile gain on an aggressive setup

 

I just ported the one have and put a buch of RTV on it in an atempt to get to stop leaking. I plan on going to the dyno this weekend so we will see if my port job got me anything.

What would a sheet metal intake cost me and where might I find one. A ported FAST would run me about $1000.00.
