the stock z06 heads flow AWESOME

 

Hi Guys,

Here are the latest dyno numbers for our latest Cam test. We took the already good cam that we had for the Z06 and changed it up some to come up with the following results.

546.6 rwhp 505.7 rwtq with LG Cam and LG Pro Long Tube headers.

We are working on our Final specs for our G7X-2 cam for the new Z06. And this looks like where we will stop for the X-2 cam. then on to the G7X-3 amd upward.

Of course we are using our LG Pro Long Tube headers which are still the standard of the Corvette market. And these numbers are WITH CATS.

We also use fully welded Merge collectors to avoid air leaks when slip on collectors are welded on. Slip on collectors will leak in the 30% of tubing that can not be welded. This will fool your 02 sensors with air infiltration, so we supply our headers with fully 360 degree welded Merge collectors.

We are still without tuning for a couple more weeks but that should just help to clean up the numbers and help the final results even more.

The graph has before numbers are from our 540rwhp 489rwtq cam. Our goal was to exceed 500 rear wheel torque, and you can see that we did easily. in the process we picked up another 25 ft pounds of rear wheel torque at 2800 rpms and 6 more rwhp.

This is also with the same "air filter mod" which means that the stock filter is removed for now until we get a good Cold Air induction for the Z06.

Also remember that this car dynoed stock at 443rwhp so we are at over a 100 hp gain.

thanks

Can a cam be made to get the same numbers and sound very close to stock with the header for a "Sleeper" Z are is this not possible at all?.

If it is I will ship my car down as so as you give the word. Have 10k to play with. It have to sound stock for me.

 

Lou, do you know if anyone is comming out with heads for the Z that have equal or near-equal sized exaust and intake valves? Perhaps that would help maximize gain from your cams and headers.

 

Lou.

Do you know what the flow numbers on the stock heads, or, is this too early in the game.

Bruce

 

And, what are the specs on your cam? Is it a wild or mild one?

 

Nice

 

At a 13% loss thats 628BHP and 580ft-lbs of torque.

At 3,132 pounds and with 628BHP and 580ft-lbs (thats 145 more then the Porsche CGT and 100 more then the Enzo) you should be able to smoke cars such as the Enzo and CGT. All of this without programing, makes me wonder what kinda gains will be seen over these with programing.

Im assuming that your higher up cams move the torque curve up a bit in the rpm range to make more BHP. If you can get the motor to make 500 rear wheel torque at 6,500rpms then it will make 619RWHP at 6,500rpms. That will be 711BHP @ 6,500rpms.

I wonder if you will be setting up LS7s to rev higher to possibly break 8,000rpms or not?

this one already sounds stock, with the exhaust flaps closed. It is amazing how clear it sounds.

I will have the guys do another video with this cam and you will be as amazed as I am.

This cam and package, the way we did it will also be reliable. We pulled the peak power down a little so you don't need to shift anywhere near the red line.

Shifting at 6800 will be more than you would need.

thanks

flow numbers on the stock head intake port are 370+cfm at .650 lift. that is more than ANY LS6 head that we ever saw.

The cam specs are.......................:surprised

Secret :thumbsup: But actually mild by comparison.

But the Header specs are not :laughing:

Thanks

Ok, Lou, I understand, but keep me posted.... when you can release these specs, I will want to compare with what else is available....

I am interested.

Bruce

 

Actually, the G7X-3 and upward is sparking my interest. Got Cam?

I will be waiting breathlessly for your new results....

Lou, this is my first post to this site. You provide some good information, however when I visit your web site there is nothing posted for the Z06, is it still in the testing process. I am in Iraq right now and will order my Z in April, #5 on the list. I was wondering what range would a package deal be. I am converting from a 350Z. I find it is better to put 20 gs down on a vehcile than upgrades to watch the motor blow. This route I can start at 500 and increase. Any information is great. I have read your thread on headers and cold intake as well.

Hi,
First, Thanks for your service.:thumbsup:

On my own car, I went with the Headers then cam. The cylinder heads are good, but we want to remove the heads for the larger cams. We will be trying cam #3 in two weeks.

We are installing cams that make peak hp at 6600 so a 6800 shift point would be in order. This will give more reliability without compromising power. that doesn't mean that you will not have power at 7000 but you can shift at 6800 and not lose anything.

feel free to email us at Sales@LGMotorsports.com and we can answer any questions that you might have.

Thanks and be safe.
