2003 TT Cobra Dyno

95Cobra_Iowa · Oct 22, 2019

I purchased this car about a year ago from a member and the only real thing it was lacking was a good fuel system. I had Mike Post at DynotuneMP install and dyno the fuel system along with a Holley EFI setup. He did a fantastic job with it and I'm excited with the results.

Pretty basic setup
Good Pistons/Rods
Stock crank
Ported Heads
Not sure on the cams
HPP Turbo kit
28lbs

He's got a video of the run on his Facebook page:

DynotuneMP

1065RWHP
910 Torque

I have a 700HP SBF and this car idles better, quieter, and drives better than that car with a mild cam.

Attached a dynosheet of the pull. Sorry I'll need to work on some pictures of the car for ya. It's a really clean 15,000 mile car. I've only had it short of a year.

The previous owners took fantastic care of it.

Pretty vague description of everything. Who did you buy it from?

Sorry, the original owner who did the lionshare of modifications had a very lengthy build thread on modularfords when the turbo and engine were put together back in 2007.

It then changed hands to a member who lives in Ohio and I purchased it from him.

The engine is an iron block bored to 284.
Oliver billet rods
Cp pistons
8.5 compression
Crower stage 3 supercharger Cams
Sullivan lower intake
Hpp upper intake
Precision 61mm ball bearing turbos .58 ar
Exhaust is out the back with cutouts.
SRA
Fore triple pump return fuel system
Holley dominator EFI
T56 street car.

I like the setup, how are you enjoyimg the holley?

95Cobra_Iowa · Oct 29, 2019

The Holley is a great system. I have the Holley HP on my 1995 Cobra. This setup is a dominator. The only downside is that it won't work with the factory dash on the 2003 because it doesn't like the vehicle speed sensor. That wasn't a problem on the 1995.

It certainly is capable of a lot more than a computer from 2003 though.

What about using one of those speedcal boxes that T45 guys use when swapping to a T56?

Those are some crazy numbers!

I just ended up going to a Holley 7.5 dash. I could have switched to a mechanical cluster too. But like the look of the Holley dash if I'm going to switch it out.

I always thought that the power and torque curve intersected at 5250, yet yours is between 6100 and 6200. Is this normal? Would making a pull in a gear other than 4th (1:1) cause this?

The scale on hp isn't the same as torque. That's what causes it to be "off".

That's correct. The torque is measured on the left side of the graph and is scaled to 1000, the horsepower scale is on the right and exceeds 1100. I've attached the Dyno so it's easier to read.
