Dyno results
Hit the dyno yesterday and ended it with 553 RWHP on a dynojet..523 and then put on the Carbon Air box and hit 553,Because we couldn't get to a plug couldn't get torque which sucked,but still happy overall..

You do know that your car is surpassing RennTech's estimates, right? With the ECU upgrade, the car should be making 625 hp. Factoring in a 22.5% transmission loss, your car is making 677.4 hp at the flywheel.

I tell you these Renntech upgrades always do more than spec. For the N/A V12 they state 25 HP but I have been told that over 30 HP has shown up at the rear wheels and have felt it. That means its probably making an extra 40 HP or so at the crank yet renntech says 25 in the lit. RenntechV12 on the SL forums had his car dyno'ed and it is putting out somewhere around 675HP running on race fuel and an eisenmann exhaust. Who needs a 65?!

Well myself and juergen the Renntech agent here in Houston had my car on the dyno all day messing tuning on it..Personally i've never been interested in Flywheel HP only RWHP the other is just a number to throw out there to make it sound better than it is..RWHP is the only one that matters especially when there is no set standard to use to correct it be it 18%,20 % or whatever it's bull compared to actuall RWHP IMO.I got 523hp first and then got 553 after I put on the carbon air box.I had my highest HP of 683..Juergen when seeing that the box made the 30 HP called Hartmut(RennTech Originator) right there on his cell and was telling him what it did.They are good friends and when he told him the 683 number I could here him on the phone say "Whatttttt"..The main reason I was doing the dyno was to check my A/F ratio to make sure I wasn't running lean which I wasn't.Overall it was a good day and I have been itching to get to the track to run it,but here in Houston at one of the local tracks they had a fatality no long ago so Baytown is very strict on the 11:49 or faster rollbar rule so I don't get many attemps at besting my 11:44,but will will see before the heat hits down here.One last thing the answer is yes I am
