FAST INTAKE FOR FI good or bad??? Hey Guys ,i Jusy Bought A Fast 90 Intake & Nw90 Tb The Other Day For My 6.0 Aps Tt Kit Someone Told Meafter I Bought It, The Fast Isnt A Good Intake To Put Boost To!!is This True ??? Should I Sell It Or Use It?? Im Planning On 15 Or So Psi !!!thanks Guys!!my Buddy Said They Leak Internally And You Gotta Keep Messen With Them !i Have A Ls6 Intake Now!! But The Fast Came With The Nw90 And I Couldnt Pass It Up !!!
You are being silly! The aps test mule that makes like 800rwhp at 20psi uses a fast 90 and 90 tb. If you go to afr website there is link to two 1000hp 400 cube big boost builds. One used the fast 90 and 90 tb and the other one used one of those carb intakes but in the picture of dyno they have a fast 90 and in the article it said the fast actually made more hp than the carb intake.
Fast is fine to around 20psi. Past that well it might need some rtv or mabye won't be the best choice. My plans for my aps are 408, I already had fast 90/ nw 90 and no intention of selliing it. Have gt7 lingenfelter cam and AFR 225 72cc heads. Good to go as far as I an concerned.

I loved it!!! But im Trying somthing new. ED the intake I sold you will not leak I had it pressureize up to 18 psi that was what I was planning on running it held great. Plus I use no rtv what so ever that was straight out the box and put together by me! Many people over tq the bolts and bend the plastic, And they dont use thread tape. Like I told you Befor Boost is a mesure of ristriction the less restriction less heat less boost you would have to run to reach your goals!!!

Good, if you have money to put towards it. like outlaw said boost is a restriction to flow, so say you can make 750HP at 15# with the FAST, the LS6 will flow a little less compared to the FAST and be a restriction, just boost at 16# and it will make the same power. obviously i made those numbers up but you get the point. As for the other part i have heard of problems with the FAST intake and boost but never actually seen anyone first hand with problems.
Also, I saw the thread you picked up the the 90/90 from, you beat me to it by 5min. If you do sell it let me know.

ive replied to these threads before, but it as all stated its not a waste of money. just that you can do more with it. ive run both manifolds. fast 90/90 and now currently run the gmpp with a nw 90tb.... car tuned and idle much smoother with the gmpp carb style manifold. but also depends on your setup as my larger cam specs liked the gmpp more. again as said by others take it for what its worth
