Yup, alcohol.
Yeah, hmmmm. Lots of things going on there. What sender/pump units are they? Doesn't matter. Biggest fittings, first!
The pump is a generic GM FlexFuel pump from a van of some sort. I figure I might try this one of two ways: higher pressure pump feeding a fuel injector(s) (of which I have a big selection) feeding the engine post turbo. Or use a couple of washer pumps and spray pre-turbo. Or both.
I still need to get some ethanol in the tank; the injectors have space for it as indicated here:
I took the car out again for a couple laps of the 'hood to dial it in a bit more - precarious given that SD requires a lot of gear and load to get right. It still has a bit of a tip in stumble - the IAC goes dead flat/closed at idle which is likely contributing to this, and I need to move the IAT sensor and filter out of the engine bay its getting a lot of heat. Otherwise I got the car transitioning into "boost" (aka power enrichment) well now and the tune is surprisingly on point (guess I don't suck that bad). I am still fiddling with the boost controller to see if I can sneak up on more oomph (the system will max out at ~14psi). The car feels very weird topping out 5psi and still reving out, when there is still so much more headroom for power and the rate of acceleration to match. The airflow is rising neatly. Too bad I am too much of a wussy to take it much higher - I really want to see/hear this thing sing the song of my people.
Pretty zippy for a bunch of junk.
