Lost torque with FAST 92 intake!! Alright guys, needless to say, i'm dissappointed. Initial run was 384 HP, 370 TQ. After replacing my LS6 intake and stock T/B, my HP went to 398 and TQ went down to 356? I was really hoping for better numbers after spending $1200. By the way, my heads are stock, I have SLP longtubes, 4:10's, and .585 cam. I guesss i'm going to have to get some heads now.
Something isn't right. Can you post up both the before and after graphs? Were the intake and throttle body the only things you replaced? Was the FAST ported? If so - by whom?
smaller engines wont get the gains those heads/cams guys will get from that intake. You will grow into it though if you do go heads..
Bigger is not always better as in your case
I kinda understand how u feel,Sometimes the internet dyno and real results dont jive..I got good results from a Ported Fast on a stout H/C car but never tested on on a cam only setup..
