Which MAF/Injectors?

det_riot · Jan 20, 2011

Well now that i'm working again, i'll be taking my car soon to get dyno tuned! Before that happens though, I'd like to upgrade my fuel system just so I don't run into any problems with all the stock stuff. As far as components, what should I be upgrading other than pump, injectors, regulator, and MAF? What brands are good to go with for each? I know the maf has to be calibrated for whatever injectors that I go with but does the mm size matter? 76mm, 80mm, etc. etc.? What about fuel pressure regulators? Adjustable I would assume or stick with the stock? Thanks guys!

Honestly,

A tune with what you have would be a waste of well earned money. You don't really have too much to upgrade...playing with timing is going to be just as good.

If you had a good set of heads that might be different. You have a 110lph pump already and the 19's/MAF are fine. The only thing you might want to consider is investing in a Kirban adjustable regulator.

Whoops, forgot to add in there that i have twisted wedges on it now =] 170cc, .650lift springs, 1.6rr's 7-angle vj and hardened pushrods.

I would do 24lb injectors, PMAS Velocity Meter and a Kirban regulator.

You could upgrade the pump but it's not necessary until you go with more power.

As far as the maf, what size should I go with? 80? 90? does it really matteR?

I have had really good luck with my 90mm Lighting MAF. It's accurate, easy to tune and from what I've heard very reliable because its factory Ford and they aren't priced too bad either. Only thing is you'll need to either splice your MAF wires or buy the harness to run it with your 94. Oh and a tune fo sho.

a nasty intake setup to go with that setup would be a lightning mass air into 4" piping into an accufab race throttlebody with 4" opening, if you are running the 90mm lmaf i would get atleast a 90mm throttlebody, i agree with lafenatu about the 24's, however you will have to get them to tune the lmaf or get u a moates quarterhorse and do the shit yourself

What size throttle body do you have on yours and injectors?

70mm TB, i had 24lb injectors with my head/cam setup and now I run 42lbers with the KB. Nice thing about the LMAF is it's not calibrated for any injector size so it can be used with any setup.

And no need for a 4" intake with the 90mm MAF, 90mm is 3.5" which is the size of the standard intake tube. It does use 4" couplers though.

go BIG or go home....

I am suprised you are still running stock injectors with all that. I have heard that going too big on the maf/tb can be bad but now sure what that line is that you shouldn't cross.

red94gt5.0 · Jan 20, 2011

everyone has heard that including myself but i have yet to see proven dyno results to prove such statement true...

I just put the heads on in october and then it pretty much has been sitting so i haven't even driven it around with the new heads on it yet.
