Wicked Weasel @ ECS

My ECS LS7-427 build rolled out of the shop and hit the dyno today. The car was on the load dyno for some time today breaking in the engine. Load bearing is sweet and watching it in action is pretty cool especially when its your car.
This is the 2nd 427 this week. A customer had his completed this week too so we had some numbers to guess at with mine. His numbers were 550 rwhp and 550 rwtq.
Doug@ECS made some assumptions in the different setups and said my rwhp numbers would be higher and the rwtq would be lower. Well of course the tuner knows his stuff and although these are only prelim numbers they came in at 565 rwhp and 540 rwtq.
Before anyone asks what the differences are I will fill you in what the differences are that I can think of off the top of my head:
Headers
Cats
Heads
Oil system
Gearing
Again these are prelim numbers and will change some over the next week. Next week we will be at Pocono doing data logging and seeing how the vararam at higher speeds affects the tune. From there we will zero in more.
I wasn't going to let the cat out of the bag yet, but Doug and I talked about adding one more change to my car before WGI in April that will raise the bar once again. Everyone will have to wait to see what it is, but what we are adding will improve engine effeciency and thus I will net more POWER (look for a new thread on this in the future) :D
So back to the current car - The dry sump system is very sweet. I have to give Johnny@ECS a ton of credit for making this happen. His dedication to this build is why this car is one of the best setups out there hands down. Having a 427 pushing these numbers is sweet, but then add the dry sump oiling system and all of the other extra components and I am confident that this setup will be track worthy for some time.
I guess I should also mention thanks to Doug@ECS for his time and effort, but we already know he is a great tuner. At one time today the car was sitting at idle and I couldnt believe how calm it was. Of course that calm turn nasty when we got into the higher rpms :D
