I'm looking to break 500rwhp N/A and I'm thinking the only way to do it is with the FAST intake. I've heard all about the leaks and problems with them but I'm still considering it .

I haven't seen a lot of truck guys running the intake, only tech guys. Post pics, thoughts, dyno sheets, ect if you are running one. Thanks guys!

 

I ran one on my turbo 5.3 but I put it on at the same time I went from 7lbs to 10 and I got a hell of a power gain lol. I never had any issues with it either. I would get one but would make it kinda last on the list. The gains are there for sure but for the money I'm sure you can find lower priced higher gain parts first. What is your whole setup?

 

mine fits no leaks or anything and it dynoed 502 and a slipping flt lvl 7 60e that died on the ride home only 25-30 mile drive and was slipping horrible and 531 it made with a rebuilt one but i dont like the tuner that did the 408 so im going to someone else in spring after the 80e is rebuilt and hoping for the same number witht he 80e

 

Current set up is in my sig. The heads and intake are completely stock stock and untouched. The only dyno I put the truck on was the first day it was drivable after being built. It made 435rwhp and 400ft lbs. It left the dyno barely running so i don't know what to think of the numbers. They are probably close.

So far on the list, I have a 4" intake tube with card style MAF, WCCH stage two port on the heads, and maybe a mamofied FAST 102. I don't know how close that would get me.

 

Well you wont be able to run the fast 102 rt intake with those heads you will have to get the car type intake... Shouldn't be too hard to hit 500 once you get everything on it squared away.

 

Yea I contacted FAST a year ago to see if they were going to make a rectangle port truck intake but they still haven't.

 

I gotta a fast too, no complaints here, had it ported to match my heads too. Before the port work with the same heads and a Tv2 on my ls1 it put down 459 on a dynopac dyno. Now im shovin 14lbs down it without a problem.

 

car style FAST intake, 408 hadnt dynoed it yet but track passes calculated way north of 550 to the wheels !

my fully bolted 6.0 put down 480+

 

I'm running the "car style" also. It takes a little work to make it fit with the stock pullys, but I think it looks a lot better than the lsxrt.

 

I'm already running the LS3 intake so I've done the work to fit the car style intake. What are the specs on your engine?
