After many updates including 4" aluminum exhaust and intake, servo-controlled TVIS, re-plennumed intake manifold, new A2W IC, 70mm TB, and all-custom tubing, it was time to establish a new baseline pull STILL on the oem ecu. Plus it was very intruiging to see what effects the updates had on spool with the big GT3040/3082 turbo. The results did not dissapoint - the turbo spooled to 200 rwtq by 3490 RPM! This is, as far as we know, a spool record for this turbo on a 3sgte engine. Final numbers at 17 psi were 300.8 whp and 260 rwtq:

Here is a bit of historical context, the progression, and previous results:

 My very first pull on the Dynod Dynamics dyno at 10.2 psi netted 190 rwtq and 215.2 rwhp. As we approached 13 psi, we got some indications of knock, and switched to colder spark-plugs gapped at .030. This solved our knock response problem.

We proceeded to 14.2 psi, and this produced a nice 240 rwtq and 255.6 rwhp. We proceeded safely to 16 psi on pump gas, with still no knock or lean mixtures. At these hp numbers, I felt that we should switch to race gas. I set my Profec B "street setting" to 14 psi for safe measure, and made some race gas pulls.

As expected with these graphs, the drop in torque from about 6500 RPM is quite pronounced due to the stock cams. I asked him to even the Hp and Torque scales for the next pull:

Crossing the 17 psi mark with still no knock (the tech was listening on a stethoscope, and we were monitoring A/F ratios) we proceeded gingerly and ended our last pull at 19.2 psi, with still no knock thanks to the C16 gas. Attaining 290rwtq and 316 rwhp, it was more than I was expecting, and more than I felt was safe for my current setup. I backed my Profec B down to 17 psi for my "race setting."

Some HKS 264 cams with some adjustable gears would make a difference, we would see torque gains at higher rpms, and a higher horsepower threshold later in the RPM band. My stock intercooler was by far the biggest bottleneck at this stage. It had to go.

My first trip out to the track with this setup gave me consistent 13-second times on slow 60' (rookie launches) stretches, but I did manage a 13.3 at nearly 107 mph. It is listed on the official MR2 1/4-mile registry.

It was time to get on a Dynojet dyno for more comparable results.

My next outing was at Mission Speedway in Vancouver. I ran a 13.180 @ 106.81 MPH, with a 1.794s 60' time, which is my best launch. I had slight hesitation on this run, I know the car is faster yet.
