How Bad do i need a FAST intake? For the past year or so i have felt that my car is not running as well as it should at the track. Could the problem be as simple as my stock TB and Ls6 Intake?
Mods that matter:
347ci flycut Ls1 bottom end
AFR225's @59cc's not sure how much compression i have .040 gasket i believe
236/242 .615/.615 111LSA Cam
A4 built to hold 700hp, 5000 nitrous ready conveter
9" w/ 4.11
Full Weight
7.3x @ 93mph 1.58-1.60 60' 1/8mile

I dont think your #s are off. Whats your converters stall?
Dude, your a full weight TA with a 9" dont forget.
What was the DA of your best? If you dont know then its tough to say if your car is off or not.
A fast will def help...

Should help some, my car used to trap 93-94mph with an LS6 intake/stock TB and stock 243 heads but I have 37 more cubes which is proably why it ran about what your car does with nasty heads. Now with PRC 225s and a FAST 90/90mm TB it has been trapping 96mph but its shifting early too at 5900 rpm, shifting at 6500 rpm and good air im hoping for 97-98 mph.

When I did my FAST I gained from about 4500rpm on up and it was ~15-20rwhp difference from there till redline. Under that it was about the same. I spend a weekend porting it and port matching it to my heads to get the most out of it.
Wow, I am really surprised you guys are only trapping what you are...I think this has actually proven that my dyno numbers are legit. With my PRC 5.3 heads, 228/232 cam, LS6 intake I am trapping 98 in the 1/8th...
I am really surprised that your car is trapping 94 with AFR heads. I would definitely do the intake, what RPM are you shifting at?
