I think it only needs to be higher than the manifold pressure plus a bit more to get the liquid atomizing from the injector. I guess that the colder the water the better as it will have an intercooler effect as the water mists, however I doubt it will be cold enough to make much of a difference ?

It seems like you could make a gauge face and use it to display 'bout anything. Three wire hookup- probably frequency modulated. Kind of big, but it's so cheap! (I haven't fooled with it since it arrived, don't even know if the thing works). Anyway, that's one idea for an analog movement.

BTW, for anyone interested in the kind of things Princess sells, especially in the electrical end, there is a place in B.C. that has similar stuff, in large quantities. Friesen Electric in Clearbrook is worth a try for the obscure and even weird. They also seem knowledgable.

I just had a thought: how about replacing your car's whole intrument cluster with a sheet of this stuff? So instead of staring at a whole bunch of black faced gauges nestled on top of a black "bezel" (couldn't think of the right word), you can be looking at a slate of white that glows at night....

It used to be an all-motorsport company, but now he has switched to entirely Efi-stuff. He's currently supporting Skoda's Kitcar-builders, in their World Championship Programme. These Skoda's are running a twin-injector TPI setup. I'm living not very far away from his place, so if there's any "hands on"-info you would like then i could try and visit him. ------------------------------ End of DIY_EFI Digest V2 #307 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
