Another Wreck, another Race Car.....

Car is all back together now and up and running on e85.

I've just fired it up and bought it up to temp. Now it has to cool down overnight so I can re torque the head when it's stone cold.

Off to the Dyno on Monday for a retune.

These guys do really nice head work. Their valve seat cutter is CNC and they cut a smooth transition into the port.

Degreeing in the cams was fun. The guys from Orger who fixed the head double checked my work.

Dyno results turned out to be exactly the same as the 105 ULP.

Even with the Schrick Cams the curve was exactly the same.

To make the car run I just upped the injector timing by 30 %.

Once on the dyno the low range was a little lean and the high range was a little rich.

Advancing the timing didn't bring the power up any so we left it in the safe zone.

I guess the 105 and e85 have similar horsepower potential and airflow through the motor is the limiting factor.

I'm running at Sandown tomorrow, it'll be interesting to see how much extra fuel it uses and if it drives the same.

Worth while for the price difference and availability to 105

Yep, e85 is about $1.33 /L.

The 105 is $4.25 /L and a 3 hour round trip to Derimut to collect it.

I have 2 United Servos that sell e85 within 10 minutes of home.

Car ran well yesterday, was getting consistently down to 1:28 when traffic allowed.

I've changed rear master cylinder, the rear bias seems a lot better now and the car is more stable under brakes. Still need to really dial it in.
