Yes at the crank shaft? I have many items on already but I would like to hear from someone that has gotten actual dyno numbers that would indicate 550 HP at the crank, thanks

That's not too difficult to get with an 03-04 Cobra. If you have 550 at the flywheel and you take out 15% due to drivetrain loss then you need 467 at the rear wheels to get what you are trying to accomplish.

You will need the following to get to the 550 hp at the flywheel:

Cold Air Kit
New Catback and high flow cats or OR pipe
Smaller Blower pulley - Lightning pulley
Chip for pulley - Have it dyno tuned for maximum efficiency

With these 4 modifications, you will easily be on your way to 550 at the flywheel. However, future club newsletters will contain this and more. :thumbsup:

You had some great numbers. Unfortunately, I was not happy with my numbers at all. I'll give the details later with a graph but some things made me feel good while others did not. They'll be a write-up on the front page of the website concerning the dyno results.

On a most positive note, it was awesome to see a slew of Cobras there and we had 17 people dyno their cars which made for a good turn out at the event. I'm glad you came up. Another great thing was that we got two more club members and that in itself was worth it to me.
