Seems a bit conservative for a 2.9. My cobra runs a whipple 2.3 Gen 2 at 18 lbs boost and 9:1 pistons and I Dynojet at 621/595 wheel.

Aaron Bahin. Correct, most all my street car tunes are conservative. also, there are a few other variables here. First, my dyno does read quite a bit lower than most dyno's being a Mustang Dyno. Second, the car in the vid is a street car 100% that occasionally gets road coarse duty. I don't ice down or "cool down" cars between runs, to try to keep all numbers similar for comparisons sake. This can be pushed a lot harder on better fuel and in a proper cool down strategy for sure. I dont have the availability here in Canada for E85 readily, that would be a huge game changer. Thanks for your comment.

tominator. Yes the tune is conservative for sure due to the fuel type and that its a street car. My personal 04 cobra has a stock motor with a gen2 whipple 2.3 and 19psi boost made 608rwhp and trapped 10.75@136 at full wieght with just a CCW drag pack on it. My dyno does read quite a bit lower than a dynojet. Also to add, a whipple 2.3 at lower boost 14-17psi will out-shine a 2.9 gen2 every day. now once you get above 20psi...its a different story. Thanks for the comment.

@@JMSPERFORMANCE Thanks for the info! I didn't know that about the 2.3. And I too have the same issue with lack of E85 availability. It is a real pita. Fortunately NJ does have some great 93 octane gas stations like BP and Sunoco. Good video!

I was just about to ask about the low numbers but I read the previous comments. Seeing as this is a mustang dyno, the numbers make sense now. Couple questions: are you on stock manifolds or running headers? And what Gen 2.9 whipple?

It is a Gen 1 whipple 2.9, It has Bassani Mid lengths on it with a 2.5" exhaust. The tune is conservative for sure since its a new motor and our pump fuel is not really that great. My own 04 cobra with stock motor and whipple 2.3 on a healthy tune with a mix of racefuel makes 625rwhp and has ran a best of 10.75@134mph fwiw.

our dyno does read quite a bit lower than a dyno jet (10-12% lower) as seen with other local dynos...but we arent racing dynos
