Converted the 1997 OBDII TBW to OBDI w/ AEM EMS. The Conversion included pedal assembly, engine harness, intake manifold, throttle body, and throttle cable from an earlier 3.0L. The conversion was NOT easy...lots and lots of tracing, re-pinning, and removing of factory wires...definately not for the weak of heart.
The setup includes a BaschBoost supercharger, AEM EMS, 3 boost pulleys (8 and 11 psi from Basch, custom high boost pulley untested), low compression build, Walbro 255 pump, RC 720cc injectors, air/water IC, test pipes, and Thermal exhaust.
Roughly 15 minutes after initial startup we had the cold start and idle nailed. 4 Runs later on the dyno with the 11 psi pulley, air fuel ratios were settling in and the car was running flawlessly. We ended up with 405 hp and 285 ft. lbs at 8000RPM - unfortunately, I believe we are approaching the limits of the fuel pump. Air/Fuel climbs a little lean and hp dropped off on top even with the 720s no matter how much we increased the pulse width. I deffinately think there is 425 whp available at this boost with fuel system improvements and closer to 475 on our high boost pulley that was made last week (should be around 14 - 15 psi). Out of the box with 8 psi and the Basch/Split Second fuel and timing controller, the car made 351 whp.
Last point - our in-house dyno is a brand new in-ground MD AWD (inertia / Eddy current loading). After seeing some of the other Dynojet graphs out there for similar setups, our numbers appear low in comparison. We will be running some back to back comparisons on a local Dynojet 248 as well to show the differences.
Will post new results as soon as possible.
