I know im gonna be bagged big time for this thread, but just to be different i would like to hear some opinions as to how to get a bit more power from CPFI without converting to MPFI. Not saying i wanna do these mods but it would be good to hear WITHOUT THE BAGGING, just what you guys think can be done to the ol 3.9 CPFI. Thanks.

I guess there's no reason why extractors and the usual mods wouldn't give you any more power. You might be able to get away with a mild cam upgrade as well.

yes, as kenaz stated, usual mods, exhaust, cam, extractors, and maybe xr6 head will give a great performance upgrade. also high performance spark plugs and leads too. cam, id recomend the wade 1636 as a start. this will get you up past the stock mpfi with exhaust people.

i recall back in the early days of the club, a guy modded up his CFI to the max, before doing the mpi conversion, as he was keen to see exactly how much the CFI setup chokes these cars.
he did cam, ported head, extractors, exhaust and manual......made something like 110 or 120rwkw. then he did the MPI conversion and it made something mad like 158 or 168rwkw... im not trying to sound like im bagging the setup, but it really isnt a good system.... ive got no idea whatso ever why ford made it available in 88, it kills any chance of making decent power, it doesnt give you any fuel economy, whats the point? i guess you could go and put a cam in, and put some extractors on if that floats your boat, but i know what my first mod will be when i get my ea...... |

I totally agree. And i know that whatever i do it will always be 20-30kw down compared to MPFI. But for the amount of time that i drive it, i just really cant be fxxxxx doing the MPFI conversion. (havent got time anyway, between work and family im flat out). I have most of the parts for the conversion (thanks heljas) but yeah, time will tell.

Yeah I was running CFI in the race car, since the mpfi conversion it jasn't looked back, 3 seconds a lap at Winton and that was when it was missing with a crook lifter. The MPFI conversion is not that hard at all, I was surprised at how easy the conversion was, it was just a few technical issues that could have happened at any time that put me back, Oh and that PINK WIRE!! Grrrr

Your EA has only seen 95 once while you've owned it? And you want a little more down low?
Swap your 2.92 diff for something like a 3.23 (3.45 max) so that you can launch better yet still have a usable 1st gear (EA 1st gear ratio is something like 3.5:1?). It won't give you any more power but it'll give you more poke at lower speeds. The change in RPMs at cruising speed would be minimal since you're doing 100% city driving by the sounds of things. You'd lose a tiny amount of poke at highway speeds (I'm talking 100kph here) but since you're never doing those speeds, and since the launch more than makes up for it, it seems like a win/win mod for your EA -Dave- |
