Build a street version so I can prove that this conversion can work in an every day application. I've already got a 987 lined up.

As far as life expectancy on the current engine... The plan is to run it at it's current power level and after the first season, if it's still alive and kicking, I'll pull the engine apart, put it back together with a Cosworth shortblock and turn the boost up and see how long the transaxle lasts at 450 whp.

Nice update. I haven't checked in for a while and you have come a long way with the car. It is truly a work of art with great attention to detail. Bravo!

I found your dyno chart interesting as well. That nearly vertical torque curve from 3.5k-4.3K must feel like getting hit with a hammer. If you bring the car back to Fontana for the Festival of Speed in April, as a very experienced Boxster driver on the Roval I would be willing to offer my services and act as test pilot for a few sessions... Purely in the interest of gathering data of course.

Yeah the power delivery is completely different than the M96. In the CalSpeed video, I was experimenting with leaving the car in third gear rather than dropping down to second to see what different RMP/boost levels would do. In second gear, the car would spool instantly with any throttle input and the back end would try to come around. In third, it I would get some turbo lag but it kept the car from lighting the tires up on corner exit.

No PCA events planned right now. We are doing the NASA event at Buttonwillow April 21-22.

That is a very busy weekend. PCA at Fontana, POC at WSIR, and NASA at BW. It's a shame these guys couldn't coordinate their event schedules better this year. Personally I think BW and Chuckwalla are better Test-N-Tune tracks when you have unknowns to uncover. I don't really like surprises at 135 mph in turn 2 at Fontana... spook city!

Keep working out those little details with the car. I think you have a winner once everything is sorted.

Any update on how this project is going? I'm glad to see someone tackling it properly.

I'm pretty excited about the prospects of your street version but am curious how you envision the electrical integration on a street vehicle. I can see stand alone engine management but am wondering if the CAN bus system for the rest of the car will freak out with the engine missing.
