All tested with complete stock exhaust.

Test 1 - Accufab throttle body and K&N filter.
Test 2 - With 3" pulley added.
Test 3 - With MAC 95mm Straight Shot added.

Testers Comments:

1 - Needs tune, running a little rich.
2 - Needs exhaust, then tuned.
3 - Have blower entry ported.

Test was scanned, some text didn't align good and prints different fonts! But numbers line up.pdf file recieved from mac

Only 349 ported? One thing about these Cobra's is there is no such thing as stock. They are all over the charts coming from the factory..

Keep in mind this is a superflow dyno and the numbers are STP corrected. To be honest, I'm not sure what type of dyno the superflow is or what the correction factor is but comparing them to your standard dynojet, SAE numbers may not be an accurate comparison.

Very interesting numbers! Thanks for posting!

Yeah, I'd like to see some SAE corrected numbers.

Ya me too! I'd like to see Dynojet SAE numbers. From what I'm told the Superflow dyno is similar to the Mustang dyno as far as the numbers go.

U.M.

P.S. I find this test performed by MAC somewhat suspicious myself... I mean, what's the first mod 99.99999% of all 03/04 Cobra owners perform? CAI & Cat-back. Why on gods green earth would they perform a test like this with the stock exhaust? Maybe because the numbers reported are higher than if the car had an aftermarket exhaust that flowed better?

Jpjr I didn't want to add my opinion or summarize the results. I just posted mac's pdf file.I'll get heat for just posting.
Thanks!
well u.m. has clouded a post that was just for general info.yes dyno was with stock exhaust .and was done by westech not mac. will have new dyno with prochamber & cat-back soon.
 
I just dynoed my 03 Cobra and I came out with 386 RWHP and 365 TQ. That was with an Accufab throttle and the crappy MAC 90 degree bend CAI and the stock exhaust. I was way fat (10.5).

The CAI has been replaced with a JLT RAI and the exhaust is gone within the month. If those 2 things lean it out slightly I should be in great shape.

BTW - I bought it used and the previous owner but the stuff on...I would have done a good CAI and exhaust first, but hey, an Accufab throttle that I don't ahve to pay for is OK in my book
