My BW S475 project... lots of pics.
Today Gus and friend Danne was sorting out the wiring blues
Some more work to do, but i've finished Gus motor with some grinding of the front cover
Tomorrow hopefully motor is in the car
Shall be really interesting to hear the new "beast" come alive. Street testing with the Autronic auto tune and then heading for the RotoTest
Then we will see...

Soon the new engine is to be started
Autronic SM4 and the 500R cdi ignition ha sooo many cables to be wiring in
First Rototest hub dyno, then goes the engine out to be seriously mapped and dyno'ed on a SuperFlow 901 bench
Then if Gus makes some serious hp the engine will go back to the FD engine bay, and then hit the strip

been doing some street driving now and everything seems to work, im very impressed with the autronic unit so far. the car runs flawlessly both on vacuum and on boost
im at about 21-22psi now.. i feel im ready for some 30psi tuning...
im also trying to setup the 2-step/launch control, i've been reading alot on the subject but all information is for piston engines... anyone that can guide me how to set it up properly on autronic for a rotary?

I request, as I am sure many do, VIDEO!!
Can you share some data on how that bw s475 spools on a large street ported engine? I am running the exact same turbo and plan to be on the dyno next week.

3'rd gear pull 24,5psi , not much drama there

still on a pretty rich tune up... its crazy fast even though it doesn't show on the video

im seeing 25psi at 5000rpm.
GL on the dyno!
i've got some good news and some bad news.
I was at the track today and i set a PB at 10.8 with a crappy 1.7 60ft...
Had big problems with my burnouts and i all my 60ft sucked.. either it bogged or wheelspin. i guess i need more seat time
the bad news is i hurt the motor, one apex on the rear rotor is probably stuck.. i ran into the rev limiter very hard in 1st gear (9000) and when i got into second it was running on 1½ rotor..
sad part this was the only run i didn't keep my laptop connected so i don't have a log... (they wouldn't let me keep the laptop in the car)
i still havn't given up so ill take the motor apart probably in the next few days
will have some videos for you guys soon..

well i guess its a part of the game.. as long as i can learn something from it to prevent it next time..
I will get a vid from inside of the car and hopefully i can see the AFR's.. then maybe some of you guys can give me some hints of what happened..

rear rotor bearing had spun 180dgr, no harm done to the excentric shaft(!) the rotor tip had made a very small touch to the housing but didn't leave a mark... i could just slide the apex out of the groove and there is nothing wrong with the seal.
housing and irons looks mint.
