    She starts and runs. We will complete the run in tonight and then off to the dyno this week.

    Heat shields on. We changed the leads to the old leads to get the leads away from those headers.

    Running.

    A few issues;

    1. Alternator not charging battery. Alternator off for inspection/repair/replacement.
    2. Amp gauge should be a volt gauge and the amp gauge was wired up so that the power kill switch was bypassed and as such even with power off, the car was live.
    3. The video with the car pifffffting is probably the weber on No.5 & 6. The butterfly nut and brass cover shot off when the previous engine detonated. Additionally, the current engine is built for big 50 DCOE's, the webers are de-tuned and de-jetted for the last engine.
    4. Battery not strong enough. Can barely turn the flywheel.

    Hopefully dyno early next week.

    So very close now.

    We'll put all wiring in heat shields and will get small heat shields for the leads. The temp on the extractors got to 387 degrees C. We will fix the heat shields that are just sitting for first start up. We will weld 2 oil overflow outlets into the rocker cover and blank off the plastic one we used for first startup.

    All back together and off to dyno today. Still need to fix oil temp sensor and place in right location and get a better higher amp battery.

    Current video of my mechanic loading the car onto the tray-top ready to head off to the dyno.

    Just had results back from the dyno guy. 347hp at flywheel. 38mm/39mm conical chokes in the 45 DCOE's. Could have gone up to 41mm as engine power lineal to 6800rpm but then dropped off. Redline is 7200rpm.

    Engine had no dips. Loved the 38 chokes and corresponding jets so that's where she stays.

    I called Pip Barker (JPS racing team mechanic) who notes that when the first Group C engines came out from Germany there was one put together and two in parts. The head race engine builder from Germany came out and spent time with Pip dyno'ing the engine in Grice's garage (Grice is a famous and very successful Group C and Group A Australian touring car driver). Apparently when it went on the bench dyno it did not even make 300hp.

    This is the single cam Group C engine. It has the M1 bottom end so can go to 8000rpm. Pip and the BMW Germany engine specialist fiddled with it for two weeks and eventually ended up with 350hp (changed pump settings, timing, everything they could).

    Grice was hoping for 380hp as the M1's were running 475hp with the twin cam head but identical bottom end. The BMW Germany guy said "don't worry about it, wait until it is in the car, it will be a rocket.

    Grice was apparently very sceptical'. After completion of testing Grice stated that it felt like it had 400hp and was delighted with the results.

    Funnily enough, pistons from the Group C spare parts shelf in Grice's garage back in the early 80's are now in my engine.

    It sure sounds nice in the video! I guess that means about 300whp, so it ought to be pretty quick!

    The E3 is home. Drove her home on Saturday. Arms still ache. No 90 degree turns on the street.

    She is a handful at low speed. Track testing to come in the following months. Will get some additional vids and photos as well.

    Yep, stopped of at the BP off James Ruse Drive. Then headed home. Not for the road. Hard to turn at corners at low speed. Race tracks tend not to have 30km/h 90 degree corners. Designed for 4000rpm to 72000rpm not 2000rpm. Hot and exhausting. Shall look for a nice trailer in the new year.
