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