Dyno graph request: E-force versus centri kits

There is a local A6 grandsport with the e-force kit that ran ~11.7@126mph
My car w/ an M6 and a procharger D1 kit ran 10.80@135mph
We both were on NT05R tires and cut 1.7X 60' times.
No dyno, but just an idea of the two kits. Both motors were 100% stock. Obviously there's a major difference in power between the cars, but that's part of the difference between an e-force and a centri setup... eforce seems to be somewhat limited from what I've seen and in real world driving gets hotter than the dyno conditions and loses some power.
Just my 2 cents.

I'll see if the local shop can get some dynos of e-force vs ECS. I know they did an Eforce headers 09 vette that did 540rwhp. Then they did an ECS headers 06 vette that mad 580rwh. The ECS vette is WAY faster and keeps making 570+rwhp run after run. The Eforce car was down to 495rwhp after 4 dyno pulls.

Don't get me wrong - I appreciate your contributions as I know it can take time to dig up graphs and post here. And I think your graphs will nonetheless be helpful for many people here (specifically those interested in what a cam can do to an otherwise stock longblock + SC), as well as a general overview of what each system can do.
I am personally interested from the perspective of the DIY-er at home slapping one of these kits on his bone stock LS3, and comparing the two for advantages and disadvantages and knowing what to expect - with dynos of some of the most respected shops on the forum to keep things fair.
Thanks again for your post,

My otherwise stock LS2 with eforce and headers, and 3.42 gears is more than capable of scaring the $%## out of me. It seems that those that want the best 1/4 mile times would probably be best off with a centri. I run at the track occasionally for fun but am not obsessed with the times and both systems have more than enough power for the street. I think either are great and everyone has their own reasons for choosing one over the other.

Few days apart, same dyno same tuner.
2008 with ECS kit, kooks headers
596rwhp/568rqtw
ECS car makes 400rwtq at 2500 and passes 500ft/lbs at 3600rpm and maintains 500+ to redline. To me that is more than enough torque.

Here is my ls-3 graph with 578rwhp and 530rwhp with 9psi.

Now get these onto a graph, save, and then repost every time another one of these threads pop up.

and both systems have more than enough power for the street
I dont see how that perpetuates a myth that centris are quarter mile blowers.
Its like buying anything. A jacket for example. One person buys it for looks, another for warmth, and another for price, but each will be satisfied because the fullfulled their need. The needs are not the same.

The sad thing would be posting 4 back to back runs. The eforce will be down another 50hp while the ECS is making the same power.

I am very sorry. I always try not to do that, but I dont know where your comment came from.
