Fms ported heads, Fms custom cam, Fms dyno tuning, k&n fipk, ASM headers, Stock y pipe with cats, magnaflow exhaust, yank 3000, 4.10 gears, Asp underdrive pulley, electric fans.

 

and all thru stock cats? damn that is nice. that makes me want to go and put some carsound cats back on mine. hey isnt that with the stock valve sizes in the heads you have. i think i remember you saying something about that before. that is nice.

 

you should change your sig to...
"May god have mercy upon your dyno, because I wont"


those are some good #s
over 100 more than mine

 

I made 229/29x untuned with:
-K&N FIPK
-FMS Ported TB
-Free Mods
-LaPole Mid-length Headers
-Crane Cam (208/216-.530/.530-113)
-True Duals w/ cats (2 1/2" Dynomax Bullets)

After the FMS tune, it made 270rwhp/290rwtq. Track time with the mods above, 15.011 @ 94mph

Then I added the ASP Crank Pulley and Electric fans and made 286rwhp/296rwtq in second gear with the 3.42s. Went to the track after the pulley/fans= 14.86 @ 94mph

Added the cut-outs and 3.90s = 14.53 @ 94.86 mph

The link in my sig has a pic of the before and after dyno tune by Allan Futral, it was done at thunder, because FMS didn't have a dyno at the time.

 

holy ****
379 to the wheels NA! WTF there are alot of 5.3's with FI setups that dont make that. What were the specs on the heads and cam combo.

 

the post above his is making 340 to the wheels with cam and boltons.

 

What has your truck run with this setup ?

 

He ran I believe a 13.3 @ 100 w/ a 1.9 60'

He's got some more stuff coming up, but I'll shut up now and let him do the talking

 

2001 rcLb 5.3 2wd 14.7
mods : ram air, TB spacer, descreened MAF , no cats, blo-master 40 turned down, 4.11's and tru-trac, predator (spinning)

 

Yeah, I went to the track a few weeks ago. It was my first time on et streets so when I first started running them I had about 20 lbs of pressure in them and they were spinning. I finally got them to hook up with about 16 lbs in them. I ran a 13.3 @ 100 on that run. My shift points were also still set at 6200 rpm from my last cam, and that is where my hp peaks, so now I am going to get a yank 3200 and up my shift points to 6600 rpm for the next time. weather was in the sixties that time out. If I can get my 60's down I hope to see some high twelves. In fact, I know that they are there, I just have to get all my stuff together.
