Default Re: Budget pre turbo WI

Update:

Since Im not traveling until tomorrow, I could not wait to do a bench test of the system. The results were... poor.

I measured the injector cc/min, it was 200cc @ 2.5 bar. My total fuel injected at boost is approx 2000cc, so thats 10% at high RPM , a bit lower at lower RPM and full boost. So far so good.

However, the fuel injector has a terrible spray, and is probably not the best this application. I didnt bother uploading my own test video, I just found one online showing my point:

If this is pointed downstream towards the turbo, it will hit it with a giant "beam" of water... Weather or not that is a good thing is hard to tell, really. I mean, its probably not that much worse then a good old "suck through" carburator setup. Perhaps I should make the spray not hit directly on the compressor, and rater strike 90degrees down and hit the inlet hose...

Ill do some further testing and see what I can figure out.. Probably in 2-3 weeks... Ill study old style WI to see what they did back in the days..
