One of the locals fell on some hard times, his plans changed and his 930 was sold, so he offered me a smoking deal on an EFI system.
SDS EM5-F /6 system with twin plug coil packs, Siemens 55lb injectors, cold start valve, crank trigger and /6 trigger mount, extra relay outputs (had meth injection), Beru plug wires X2, manuals, base maps, dizzy hole block off, Bosch one wire (Djet) head temp sender plus all the cabling, fuses, etc that are not included with an SDS system. I already have a Wabro 300hp FI pump, a Djet fuel pressure regulator, 14point7 wideband O2 meter and an O2 bung in both headers. This is not a discussion on which Aftermarket EFI system is better, etc but rather on plenum based intake design. I'm not new. I've been playing with a SDS EM4-F /4 system since 2003-2004 that's now on my '67 bug T4 2600cc conversion, I know that ITB's are better for peak HP, but I'm after overall improvement, usable vacuum signal for MAP, drivability, fuel economy and etc. FYI I have also asked this on the bird board here for some more info on the build. This thread shows my /6 conversion a few years back and has all the engine specs here. Plus I've built my own motorcycle ITB's before here. Please I only want to discuss a single TB plenum based intake for performance EFI. |

Cool Steve, do you have any more pics of your intake?
All I need is a TB with a TPS on it, that why I thought of the mustang TB, I'll start looking at sizes. I'll have to wait a bit on the manifolds, Clay's area is getting hammered with the cold and power problems, obviously I told Clay I'm not in a rush. Plus I think he has to remember where he put them. (IMG:style_emoticons/default/biggrin.gif) In the meantime I'm going to clean the system up and start planning on where I'm going to mount the ECU, wiring, programmer, etc. It has the crank trigger on a plate that bolts to the pulley, but it's a two groove pulley and I think my mount only fits a one groove. So I have lots of little jobs to do. |
