Went to a dyno day this past Saturday and got around to loading the sheet. I figured I would post it up. I was pretty happy with it, I predicted 2hp higher, lol.

JLT Intake
Full Exhaust (Bassani and FR500 bits)

Oh, and for some reason it recorded speed instead of rpm but it was in 4th so I'll figure out what rpm the peaks were using a gear calculator.

That's to the wheels?! Impressive for a 'stock' Cobra. What's not stock about it? Just exhaust and intake? I would have guessed way lower. :hmm:

Yes, to the wheels :icon_wink

Just intake/exhaust and a pig rich stock tune (JLT intake is notorious for this). I have no doubt theres another 10-12hp in her with a little leaner fuel map and nothing else (confirmed on a couple other JLT equipped cars).

A/F wasn't hooked up, ignore it, lol

With HP and TQ plotted on the same scales, the lines should cross at 5,252rpms.

So what's up??

WASN'T THIS THE YEAR that Ford recalled the cobra's because they weren't making the claimed 320hp?

Regardless - still healthy numbers.

Yes. However, Ford offered a recall and the previous owner has the paperwork proving it was done. They did a retune and swapped the intake manifold.

Oh, and I'll have to look into the 5252 thing, I'll ask the shop tomorrow.
