Any progress on V8 engine swap options?

[specboxCO]

This thread has gone a bit quiet lately, so I thought I would post something motivational.

I have completed my V8 swap and got it to the track for its first test.

Might not look like much, but its been 2 years in the building. Runs a 40v 2002 Audi 4.2 using an Audi ecu, Cayman 5 speed transmission (may swap to a 6 speed now I have the VSS problem sorted) volvo electric power steering, BMW ABS system.

Will be racing it in 2 weeks at High Plains Raceway in Denver in the World Racing League endurance series.

It sounds great! I'm considering picking up another 986 and doing an Audi 2.7t swap. I would be interested in your thoughts on the v-8 vs the v-6 choice.

[specboxCO]

I think the 2.7t is a much better idea for a daily driver or occasional track car. Can make way more power than the V8 and is probably an easier install.

I wanted the V8, as I was building an endurance racing car and wanted an NA. Turbos seem to cause a lot of issue there, difficult to get the heat out of the car. Plus it sounds great!

Did changing that value in the ECU program solve the VSS issue? Did you eliminate the cluster from the trunk?

Yes. Managed to up the rev limit in the ECU for the No VSS issue. Runs perfectly now.

Gavin, How did it perform on the track? I saw video of the start and it looked like you were in GP0.

[specboxCO]

Performed great for around 5 hours, then a weird fueling issue took us out of the race. Car would idle fine, but would get around 2 laps, cough and die, unable to restart for 10 minutes, then fine again. Thinking some kind of vapor lock issue in the system

Will be going over datalogs this week to try and understand what happened.

I have a friend that races in autocross and had that problem twice. One was the fuel pump getting too hot and he noticed it happening more as the fuel level went down. It was a return fuel system. Cold fuel going out and hotter fuel coming back. The second time he had a similar issue was when he had the DME mounted right above the exhaust on the trunk floor. The exhaust heat was overheating the DME.
