SN65 Dyno results

[SN65]

Yesterday, we had the SN65 out at Finish Line Performance (Naperville, IL) for a dyno session. We made 7 runs, made a few adjustments and ended up with a max rear wheel power of 402.4 and a max rear wheel torque of 396.4. This is an increase of about 40/40 over the original factory numbers.

We found that the original plugs were not up to snuff and would randomly miss causing a 30 to 50 HP drop per incident (miss). After changing out the plugs and fine tuning the fuel curve, etc... we ended up with a much smoother operating powerplant.

It was a fun time and we are now looking to up the power to about 550 RWHP with 550 RWT. We are talking to Whipple about a blower upgrade and the expected results.

The graph I have is pretty hard to read. It has all 7 runs on one sheet and they all kind of blend together. The HP graph is a straight line from 200 HP at 2,700 RPM to 400 HP at 5,600. The torque is pretty flat starting at 368 at 2,900 to 380 at 5,200 RPM. Max torque was 395ish in the 3,500 to 4,000 range.

O i thought those motors rev like the 4v cobras? How much does that GT weigh anyway.

I just posted a video of the dyno session at the Sn65 website.

Mods to the 03 Cobra engine are just a CAI and a full Magnaflow exhaust including cats.
