2006 Z06 Dyno with LG Pro Long Tube Headers Hi guys,
All this information is with our LG pro Long Tube system WITH cats.
This Z06 is owned by REDLINE OIL president, Tim Kerrigan. He had the car sent directly to us at LG Motorsports. We appreciate his confidence in us.
I will start with some facts. We installed the headers today with only one minor change to our 3" mid pipes. The C6 necks down to 2.5" but the Z06 has 3" mufflers. This only required a small change in our system to eliminate the 2.5" neck down and continue our 3" pipes to attach to the stock 3" mufflers.
ok Results. First I have to clarify some knowledge that I gained in the last 24 hours. Without being able to tune the PCM, Temperature makes a big difference. I am sure that Temperature also lowered our Base line numbers also. So the 443rwhp would have been higher had we cooled the car down more before we did 2 runs back to back.
Our "After" header install numbers were not up to where we thought they should be so we let the car cool down for about 30 minutes then we did 4 pulls in a row with only 2 minutes seperating each pull.
There is no way that I was going to just pick the best After pull and call it good.
Here is all the information for you to digest. the temp on the 3rd or 4th after pull was about equal to the baseline pull, so use this information wisely.
Also note that once we can get into the computer we will be able to go in and "affect" the changes in timing and other parameters that are pulling the power out.
The air fuel went from a 12.2 on the best run to an 11.7 on the worst run (in the 4 run graph)
The first graph is the base line, with a warm engine) against the cool engine pull with a 30 minute cool down.
The second graph is 4 pulls in a row, 2 minutes apart showing heat build up and the effects of the heat on the power.
Base line/After header install with cool engine
4 pulls in a row below
You can see that the computer pulls about 16 rwhp out and 13rwtq
by doing 4 pulls back to back within 6 minutes total from starting the first pull.
Tuning will solve this easily.

Yes and no. If you read my explaination you will see that the PCM is either pulling timing or affecting the Throttle position which kills some power.
The last pull on the 4 pull chart shows a 16 hp loss from heat. We wanted to make sure that everyone knows that the original baseline pulls were 2 in a row and the car only cooled down for about 15 minutes. So there was heat soak in the base line numbers also.
We will get another Z06 coming in this sat and we will do a baseline pull with the car after is cools for 30 minutes to get the real base line.
Thanks

This car has so much potential it is sinful.
This will be a bolt on 500/500 car for sure. We just pulled the air filter out and picked up to 487 rwhp 465rwtq. Keep in mind that is stock with just our LG Headers and cats.
More to come .

Check out the torque. It is above 400rwtq from the instant I floored it at 2800 rpms!

What I'm curious to know is what it would pickup without the cats? Would that alone be enough to push it over the 500 mark with a spot on tune.
Peace,
