Engine dyno results
This is a quick copy of Data print out.
we had to stop run at 7000 rpm, injects went to 100% duty cycle.
Time for bigger injectors.
RPM Ft/LBs HP MAP
3500 232.5 154.9 7.1
4000 245.4 186.9 8.2
4500 338.8 290.3 13.5
5000 446.7 433.7 22.1
5500 456.7 495.6 22.4
6000 468.4 526.5 23.2
6500 429.2 523.1 22.2
7000 491.4 608.1 23.3 Injectors hit 16ms
These were 750cc siemens injectors at 80%
They were already maxxed out at 6500rpm, we then just turned up fiel pressure to get extra 500 rpm.
However 1000cc are ordered, they should hopefully do the trick.
I have finnished on engine dyno for now, i have to get finnished another engine with a similar setup.

Re: Thats a damn big turbo to have a torque peak at 7000rpm!!
Did not peak yet, we aborted the run at 7000 when injectors hit 16ms, it was still climbing.
what i am impressed with is 7psi of boost at 3500, so still got good torque for normal driving.
over 200ft lbs, whilst the stock car had around 160ft lbs
