In driving my 914 turbo Ford I have found that I can't get much above 3500 rpm. I suspect that the Bosch pump might not be compatible with the Ford EFI. I kept the pump because it is externally mounted (vs. tank mount for the Ford pump) and I saw a guy who was successfully running a 280ZX pump (which I think is basically the same as the 914 pump) on his EFI 5.0 HO Bronco. Does anyone know the basics of the fuel pressure vs. rpm curve for a stock pump on a 1973 1.7? I think I need about 30 psi at idle and 70 psi max.

QUOTE(914turboford @ Oct 3 2003, 11:39 AM) Does anyone know the basics of the fuel pressure vs. rpm curve for a stock pump on a 1973 1.7? I think I need about 30 psi at idle and 70 psi max. there is no curve. it's good for about 35 psi and it'll deliver that at flow rate commensurate with a 135 HP 2,0 DJet at 5600 rpm or so. you might be able to get ~65 PSI with a Bosch K-Jetronic (CIS) pump but of course you'll need something that can deliver adequate volume - something from a 911 or 944 Turbo might work. there's an aftermarket pump some Rennlist guys were using as a DJet replacement, seemed like it had a lot of pressure but the stock 914 regulator was able to deal with it... can't recall who made it. Moroso ? Holley ? IAC - a DJet isn't gonna get you anywhere near 70 psi at the volumes you need... |
