Tea 1.5 And Cam Problems?
I Have Mac Mid Lenght Headers With Off Road Y
A 3 Inch Cat Back System
And FIPK Intake
Plugs,wires
And A 12 Bolt With 373 Gears
Car Made 350rwhp And 348 Tq
At Mti
I Got A Set Of Tea 5.3 Heads Ported To 1.5
And A C2 Cam 224 224 581 581 With A 112 Lobe
AFTER INSTALLED AND MTI CUSTOM TUNING
Dyno # Are 397 Rwhp
393 Tq
Some Thing Cant Be Right..????
I Was Told That This Set Up Would Gain Me An Easy 80 Hp??
What Could Be Holding Back Hp..??
Bruce
The Car Was Tuned At Mti..
And They Where Telling Me That The Heads Schould Be Making Alot More Power Then That..
At The Track
12.5 With A 1.9 60' At 114mph
12.5 With A 2.0 60' At 115mph
Thats The Best I Could Get Out Of The Car On Nitto's What Schould I Do Next To Really Make The Difference.
Tb Can I Get Mine Ported? Or Schould I Go With A Bbk?
And Iam Thinking About Going With Flp's
.. Would This Help Or What Schould I Do??
To Inprove.??
And Does The Pulley Make A Big Diference?
Trending Topics
ASP Pulley, 10 RWHP
LT headers, ~10 RWHP
TB, ~5 RWHP
You're going through a 12 bolt and 3.73s, that's sucking up about 10-18 RWHP at least. You've got that K&N FIPK, too, that has been shown to cause lower dyno #'s because it sucks in hot air. Put an air lid on it.
If you add the suggested mods above you'll EASILY put down 410+ RWHP.
Don't get so hung up on the dyno #'s either. See what your MPH is at the track, that's a true indicator of power.
Oh yeah, enjoy the car, regardless of the power #'s. I can guarantee it feels a LOT faster then when you initially dyno'd it, eh?
Also, when you go to the track, add some stickier tires so you can lower your 60' and increase your MPH.

It Does Feel Alot Faster..
Then Before When Mti Tuned It They Said The Best Place For Me To Shift It At 6,500 So Thats What I Shift At..
I Guess Iam Going To Look At Changing Out The Lid First And See If That Helps.. Looks Like The Easist Think To Do And Cheepest So Far.
If Any One Has Any More Idea's Let Me No Please
Thanks

Lou tuned my car and indicated that the 6 speed numbers would be higher than 403...somewhere around 425 or so. My cam is milder than yours, my heads are unported and I am running an automatic with an IRS that eats up even more power. I think you should be at least 405 at the wheels and I wouldn't be happy either if I were you. Your close though. I think there are likely a few simple things you can do that will bump up your power level. I'd try the filter setup first. Then address the exhaust. You gotta have a good exhaust and intake setup if your running a H/C car. The engine is ready to make power you just gotta let it breath more.
So schould I keep my headers.. And just get a Pulley and have my throttle Body ported..
I have the graph but i dont no how to post it on here if some one know's please tell me and I willbe happy to post it so u can see whats going no and maby help figure things out..

honestly 397 aint nothing to sneeze at and like caninbal said dont get caught up in dyno numbers.
This is like saying every head we port makes 400 or 420 or 440 or something else. Every set of heads we do gets flowed and if it stalls below .600" lift it goes back to the porting room.
Once again I say, if Speed Inc has made 448 with the 224/224 .581"/.581" cam and have seen 10-20 RWHP from highest to lowest (where they used to see 40 RWHP with the hand ported heads they used to get) then how come everyone jumps on top of the heads everytime a car doesn't make power? We have sold many sets to GMMG and they have seen 449 through a 12 bolt rearend. It is a mystery to me how there can be that much difference in the heads especially if they are CNC ported? But once again I say, could my employees have slid one out the door that wasn't up to par? I hope for their sake not, they understand that their livelihood is on the line with every set we send out. That is also why I say if someone has a pair of our heads that do not make power and they think that is their sole problem and they are considering pulling them off, then I will send them a replacement set to bolt one and then they send that set back. But if they do this and the car doesn't pick up 10 RWHP, which I would say would be the biggest difference then what are they to do then?
Here is one thing to consider, in one of my conversations with Judson at S.A.M. he said they have found up to 50 HP in the wiring harness alone. He has seen on his dyno changing nothing but the harness BIG power differences. How is this possible? I don't know, if I did I guess I would be in the wiring harness business. There are more possibilities then someone can shake a stick at, so don't always shake it at the heads, after all they are CNC ported so how much different can they be from set to set? Hope this helps.
1- why did you have Judson design the ls6 port for you?
2- are you capable of designing your own ls6 port design that will perform up to par with others in the industry?
3- what wiring harness are you talking about, the engine harness or dyno harness?
4- how many sets have you gotten back from low dynoing cars and did you find anything in the heads that could play a role in low results?
5- do you really think a well working wiring harness can cuase major loss in power?
