Project Racer - Monday 20.02.2012/XNUMX/XNUMX
The engine for our racer is being put to the test today.
For settings and a performance measurement, we mount the motor on a work stand.
As seen above, we first check the ignition timing. With a stroboscopic lamp you can see whether the markings are correctly aligned with one another.
The picture above is at 2500rpm-1 emerged, this speed should be observed at least when checking the ignition markings, as the Ignition curve of Vespatronic above and below this speed already runs into the adjustment range.
Here on the assembly stand.
We equip the “throw nozzle” 38 Keihin Airstriker with the following Share:
Idle jet 52
DDJ needle, 3rd clip from the top
Main jet 165
After checking whether everything couples and shifts as it should and after warming up, this diagram results.
Already quite good for the first attempt with throwing nozzles.
29.1PS / 24.4Nm and a band with more than 20PS over almost 3000rpm-1 are a nice start. We'll do more tests and maybe we'll find one or the other horse.
With the certainty that our engine is working, we are eagerly awaiting the arrival of frames and attachments from Austria tomorrow.
cool, alex! more diagrams, I want to see 30 plus horses :-))
Congratulations ever on the motor - nice band and that "only" at the beginning ...
With an exhaust from pipe design it would have been over 30, so I'm sure it would be 150
