Ok, here are my mods:
233/239 .603/.600 112 lsa
90/90
35% underdrive pulley
TEA stage 2 5.3L heads
#42 injectors
LT's no cats
3" X pipe to dumps
CAI
The car was a V6, and still has the 3.23 10 bolt. It dyno'd (tuned) 415rwhp, and 383 rwtq, and 153mph in 4th gear (on dyno). Is that about right or in the ball park, to anyone who has a simular setup? I think the tuner did a good job, I was just hoping for a few more ponies. suggestions/ comments please.

Well, maybe a little low.. But, take her to the track and get the real world results.

Yea man that is kinda low. Check my mods in sig, TSP 233/239 cam only. I put down 406rwhp/374rwtq through the 9" w/ 4.11s.

Please don't freak out about the graph, this is the only one i have currently, and this was done before new plugs were put in. It smoothed out afterwards. I'll put up the correct one when I get it.

I hope the other one is smoother... looks a little "choppy"...

yeah, the correct one is very smooth. I had a fouled plug on that one. (sorry it's all i have for now)

What MAF you running?

stock, but ported. It's never given me any issues before. it's a 98 engine, and MAF

do you have HP tuner file of your setup? because i have the same TSP cam 233/239. i just put the cam and the car doesn't want to idle it will die i said maybe i need a tune. do i need to adjust the screw on the TB to raise the idle?

here are my current mods :

1- home ported heads
2- TSP 233/239 cam.
3- QTP headers.
4- Borla cat back.
5- Fast 90mm intake
6- Nick Williams 90mm TB.
7- stock programming.

i don't have hp tuner now but i will get one later this month or later next month.

my car is 2000 M6 Z28.

thanks for help.

On bigger cams like the TSP one you are running compression makes a big difference. Do you know what cc the chambers are and what head gasket are you running?

I had a stock '99 LS1 shortblock with Katech rod bolts, 62cc AFR 205's, GM MLS head gaskets, LS6 intake, TSP 233/239 cam, ported TB, 1 7/8" long tubes, dual 3" thru cats/Xpipe/muffs, T56, 3:90's and made 440rwhp @7100rpm and 385rwtq peak. My compression was around 10.7:1. With Cometic head gaskets (thinner) resulting in more compression I could've eeeked more power out of the combo.

I think you need to spin that combo higher. 6600-6800rpm and you will most likely find your missing power. That cam sings in the upper RPM band.

Anyone have sound clips of this cam? I'm interested...

You are going to definately need a gear (atleast 4.10) for some good results at the track.. M6 and a 3.23 gear is gonna suck.

Yea, that cam need to be run up to at least 6500, thats where some more power is. Who tuned the car?

im with you 100% on that one. i have the TSP 233/239, ported 59cc Patriot heads, LS6 intake, Pacesetter longtubes, it has 11.5:1 compression ratio. i cant even list all the other mods. anyways it made 468rwhp. this cam pulls well throughout the RPM range, but it pulls like a train up top.

ditto... pull it up to atleast 6500 and you will find your missing power.. the torque seems a bit low, but that could be due to low compression. my heads have 64cc combustion chambers with stock head gaskets, and i still pulled 399rwtq. i have the older version of the 233/239 with .595/.603 lift though.

TheLS1Kid

iTrader: (12)

interesting...i didnt know there was another version. do you know the specs on the newer version?

its the one this guy has... .603/.600

First version here as well and my old dyno graph shows it peaking at about 6500-6600 rpms. If I had stopped the pull at 5900 like you did then I would've been down about 13-15 RWHP from the looks of my graph. There's part of your missing HP right there. The guys at the shop should've realized that it's not flattening out that early and kept the pull going...unless you told them to stop at 6K. I also would've expected closer to 440 or more with heads. I'm redynoing this Saturday on a DJ 248 after my Fast 90/90, UD pulley, and better tuning...shooting for around 415 cam only.

62cc combustion chambers, and they were milled to .030 for clean up. I have stock GM head gaskets. I tried to get help here https://ls1tech.com/forums/generation-iii-internal-engine/479160-5-3l-head-gaskets-5-7-block.html
for head gaskets, but didn't get much. I called TEA and they said run stock gaskets. So I did. Also, the dyno graph I have posted is not the correct one, the pull shown was stopped short because of the obvious miss. That is an older one when the tune wasn't finished, when I got the final numbers that I listed in the initial post, the engine was spun to 6800 RPM, and it did get it's peak HP at about 6650RPMs or so if i remember correctly. Thanks for the help guys.

It was tuned by a reputitable LS1 shop here locally. I'd rather not state who specifically.
