5TH Injector

[WickedShelby88]

Okay guys, sure I know why you would want one. Higher fuel demands under high boost Im thinking. The idea I guess would be to have some kind of pressure/boost switch to activate this thing at a certain point. My question is what are most people doing to plumb fuel to this and where are they putting it?? Aside from that I think I got it figured out in my head for the most part whats going on but am just stumped. I guess I should ask what kind of injector should I use for this? cold start injectors from some foreign cars work I hear.

yea its been done alot before. You can use a cold start injector. Most imports have them. Set it to come on with a pressure switch. Most people start around 16psi or so. Whever it starts to lean. Better idea is use +40's and a custom cal

My first setup, stock fuel pump, injectors, hobbs pressure switch and 3 VW cold starts, 18 psi,
