Re: going EFI

Chuck,

Are you considering a SPF? MK1 or11?

To your question...See my post today re Fuel Crossover and description of Spoonsoon swirl pot (IMHO needed even with the newer designed SPF tanks with additional baffels and center fuel pick up)...In addition to that O2 sensors or sensors ( if want one for ea bank) and associated fuel managment controls ...Many SPF's have been built up with Roush FI.

So what's up?

Re: going EFI

Steve, it looks like I bought an SPF MK11 with a Roush 427sr and I am considering going with a Mass Flo like EFI. Do these cars come with return bungs in the tanks? chuck

here is another slick system for the semi purist

Retrotek - BOSSEFI Single Quad

Re: going EFI

Steve, it is not here yet but I will definitly call when it gets here for some advice. It does not have the FE like I wanted ,and although quick, it does not have that kick in the ass feeling you get with the 427. No matter what anyone says, all 427 cubic inch motors are not equal. chuck

Re: going EFI

Here is a picture of a catch tank I built to fit into an area that was spare, spare room is a big problem. I have 427 with webers but will be making the conversion to EFI using electromotive down the road, I have 4 cars using electromotive and am very happy with it. I do have a friend how sells throttle bodies and manifold along with electromotive unit, he has a SPF MK2.

Re: going EFI

thanks Jack.

Mark, no real advantage over the CAV ,just a different car, more authenic and a MK11. The CAV has more interior room but both are nice cars. I appreciate the effort SPF went to make the car as genuine as possible, but you do pay a hefty premium for that.
