Full throttle Electric Supercharger Build Thread

[Grantmac]

An eductor (which that is) creates vacuum through flow. But it requires the exhaust side to have similar or less pressure than the suction line. I've built eductors to introduce methoxide in a biodiesel reactor. They are very simple devices but getting it right took work, any backpressure and there was no suction.
In a boosted application it's nothing but a boost leak.

However if you were to use it as a means of pump-less water injection then that would be awesome. The water tank would need to be under pressure as well though. I've actually got something drawn-up using a side-draft carb with the throttle plate removed.

In the lab, that's how we powered the vacuum lines for filtering and drying various extracts. Water running out of a tap, through a little thingy, and the water flow created a vacuum But yeah, put a restirction on the outlet, and water came squirting out where vacuum was supposed to be lol.

Rob and I are very interested in adding water meth injection to the current system if possible.... if anyone has good suggestions on a system let us know

This is a very interesting set up.

does anyone know when this kit will be for sale? and a price? i hope its close to the other prices they have posted for the chevy and vw

The long term fuel trim is richening our car from 8% to 12% after 2-3 weeks reflashed.

That's why your tuning have to compensate for that.

Usually after my FA20CLUB reflash I was right on the spot where we wanted 12.8 -13 but after 2 weeks I wasnt there anymore.

So what Tony did, he sent me a flash where a was leaner at first 14 -14.3.

It goes like that for 2-3 days and then gradually after 2-3 week at WOT I'm now at 12.5-13 all the way to redline.

From what I understand, by doing this we cheat the long fuel trim effect.

[mid_life_crisis]

I really don't like the fact that the tuners have to play games like that. It explains a lot about the blown seals out there. There must be a way to edit the target table to get the correct results from the start. It isn't like they're using a primitive version of an add-on processor to cheat the system: they're directly editing the processor. It shouldn't be necessary to "cheat" the system.

Check out Ptuning's stuff. I have no first hand experience with it, but what they've posted leads me to believe it's worth investigating.

Grant, that is brilliant! Do you have any plans to take it beyond the design phase? I'd love to see that come to market.

This is from ALCOHOL INJECTION SYSTEM

[nonicname]

mmmm I like this system as simple as it is.
if it's not broken don't fix it.

Pump from mopac...aem. nozzle from mopac... snow performance about 150 to 200cc.... I would flow test it to make sure it flows about 175cc or about 20 percent of fuel flow by mass. Pressure switch or wot window switch. And assorted air line fittings and hose from princess auto.... just y the supply line from your washer tank and run windhsield washer fluid.

Then re tune to give the factory knock sensors more authority to add additional timing.

[Toma]

And then once a season nozzle cleaning and flow test.
