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.

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.


Then just for fun, I pulled the air filter and made a quick pull before i left for the day. the car had been sitting for over 30 minutes.

so i am to assume this is just headers, no cam nothing correct?

Am I reading this right? Up to 40 freaking hp and 50 ft-lbs with just long tubes? That's awesome ! :cool: :cheers: :flag:

Just LG Pro Long Tube headers with cats.

the bottom graph shows 4 runs with headers installed after installation.

We did the 4 back to back so we could know exactly what was happening with heat soak.

since we could not go back and remove the headers we know that the next car will be baselined both hot, and cold to clarify the results.

Thanks

Lou, now your cookin with gas! :cheers: Some LGM long tubes, get rid of the 2.5" bottle neck and we are starting to make some good power hot or cold. I'm becoming a believer that this engine with a good tune, intake, and headers may be over 500 at the wheels like a 427 should be. Now do a cam and holy schnikees. :thumbs:

Thanks and I agree. The tune is critical

We already did remove the 2.5" bottle neck and install a full 3" connection to the stock mufflers

I assume that's Random tech high-flow cats, not the stock ones, since they'd have to be eliminated by headers, correct?

seayzo6 09-28-2005 10:40 PM

OH YEAH BABY!!!! :eek: No cam numbers, just headers. Lou's the man.

C6 Z06 Rocks.

with the stock cats or the aftermarket high flow cats?

JerriVette 09-28-2005 10:41 PM

Dam fine performance increase from headers.

483 rwhp? 460rwtq! Wow!

Congrats

Looking forward to seeing what the pcm unlocks for you.

Just call me direct. and we can work your car in.

This car is owned by the owner of RED LINE Oil, Tim Kerrigan. He had the car sent directly to us for the first mods.

My own Z06 will be in this week or next and we will try 3 different cams in it. The results of that testing will determine which cam we will install in this red Monster.

I just caught that..AWESOME!!!!!

GeneCamaro 09-28-2005 10:44 PM

Wow those are awesome number. I'm curious what the car will do stock with just a tune, no headers.

I'm also curious about that Z06 that dynoed 454RWHP on a mustang dyno from LS1Tech......
