Fair" Subject: Re: idea for an enclosure for efi_332 ecu I have an associate who has a CNC setup. He can make the enclosures for the ECU in quantify. This might work pretty well for a group buy or something. If Seth's machine shop isn't interested, I could get this going.

These do not look like the one you are describing. It sounds like the one you are thinking of is the one I got with my kit. Plain black plastic, 1/2" in/out with vacuum line. I don't have a part # for mine as it came with the kit. I can't even seem to get to Vortech's price page to see how much they would cost. http://www.vortechsuperchargers.com/bypass.html - -- Glen Beard 95 T/A conv M6 355, Vortech, heads, cam... http://home.nycap.rr.com/gbeard1/TransAm.html - ---------------------------------------------------------------------------- To unsubscribe from diy_efi, send "unsubscribe diy_efi" (without the quotes) in the body of a message (not the subject) to majordomo@xxx.org ------------------------------ Date: Wed, 09 Feb 2000 03:07:28 -0500 From: Darren Floen Subject: Carter fuel pumps Hey all,can anyone tell me the specs of this pump? Carter P74017. I still need a pump for my 4.3 TBI swap,and i've had this one kicking around...just wondering if it'll supply enough pressure. Also,i was told that my stock 45 PSI Toyota in tank pump will work,with a ballast resistor or two in the power line..since the TBI has a regulator.Will the excess fuel by-passing the injectors cause problems for me?It'd be nice if i could use the Toyota pump,since its only a year old.... Thanks all,this list has helped me alot...and i'm learning alot from it.

(Zener diode limited voltage output of stock MAP sensor at about 14 psi.) Everything over 14 psi was fueled by two auxilliary injectors that received pressure information from a Motorola MAP sensor. I used their MPX4250 pressure sensor rated to ~36 psi max... it has a linear voltage output with increasing pressure. The next higher rated sensor goes up to 72 psi max. (MPX5500) The main problem I had with mine was that it was so damn small it was hard to work with! (About the size of a pencil eraser.) Cost me about $20 & I was able to order it from Radio Shack. I heard that Motorola also has some new pressure sensors that go up to 150 psi, but I don't think you'll be running that much boost. On purpose.
