Any pics?

 

Can you post the graph with the uncorrected numbers?

I'd like to overlay my graph from MAC with yours for ****s and giggles.

 

SAE correction at high altitude throws off the numbers big time on forced induction cars. What was your correction factor for the dyno? And if you can post a uncorrected chart.

 

SAE correction factor was 1.22. Read the file on the affects of altitude that is on the first page of this post. Also, I was only running 25psi of boost on this dyno run. I'm now running 32psi, haven't been on a dyno yet. Any one who says that altitude doesn't impact the performance of turbo charged cars please join me at Bandimere were the average stock Evo runs about 14.0 to 14.6 seconds in the 1/4 mile.

I have a Kleemann supercharger Mercedes G55. Ran a 13.9 second 1/4 in Detroit. Best time at Bandimere is 14.9. Altitude kills! Turbo charger, super charged or not.

BTW, My stock evo on this same dyno with a correction factor of 1.25 put out 242.05 whp and 260 ft/lbs torque. Using that as a baseline comparison my cars power has increased by about 225%. Correction factor or not that's pretty damn impressive.

 

Actually your power is 225% of the original power, but has only increased 125% ......but who the hell cares it's damn impressive!

 

Awesome, have you had any 1/4 runs?

 

I've had one run at Bandimere which is at 6000 ft asl. I ran an 11.8 at 118mph. I'm not trying to make any excuses but it was my first run with this car and I only got to run it once since I was immediately asked by the track not to run the car again without a cage. I bogged the launch and hit the rev limiter in 2nd. Horrible run.

At sea level this run would have been equivalent to 11.44 in the 1/4 mile at 121.3 mph by using a conversion formula that takes altitude into account.

The car is currently having a cage installed in it and is now running 30-32psi of boost instead of 25psi of boost. In it's current state of tune I believe that I am making over 600 whp. The anti-lag feature of the Autronic has also been activated as has the launch control feature. I'll post new dyno results and new 1/4 mile times when this beast is done.

BTW,
The car is currently making 450awhp and 400 ft/lbs of torque on 91 octane. Water injection has been installed and will be tested with 91 octane shortly. I'm hoping for 500+ pump gas WHP.
