I WANT ME SOME MORE EFFICIENCY! I'm trying to bump up my mpg. I still have to read up about changing my timing but there's some guy on craigslist selling some stock 5.0 mustang headers for 40 bucks, is that a good deal? Also there is somebody selling 5.0 Cobra intake upper and lower for $240... So which parts would help mpg's?

I don't know if my HO upper intake and throttle body helped mpg's at all but they did at a hint of power. Plus they were cheap as hell.2020 F250 - 7.3 4x4 CCSB STX 3.55's - BAKFlip MX4

How many more mpg's do you get from them? Of all the years the explorer were built only the 96-97 have upgrade parts?Originally posted by Lincolnmania View Post88 MGM 5.0 stockComment

i built a 88 townie couple yrs ago with a brand new stock 96 explorer 5.0......with 3.55 gears and a wide ratio aod the car gets 20mpg highway and hauls ass.
96 and some 97's have the intakes with egr passages......96's have gt40 heads so you do not need gt40p specific headers........you can use the later 97-01 5.0 but you either have to eliminate the egr or get creative with egr plumbing off one of the header tubes

Would one lose any gas mileage running no EGR?Originally posted by Lincolnmania View Post2020 F250 - 7.3 4x4 CCSB STX 3.55's - BAKFlip MX4

According to Thain, and I think this makes sense, a properly-functioning EGR system is somewhat beneficial for mileage because it allows slightly leaner calibration at idle and super-light throttle conditions. Of course, if your engine is running poorly, it can tend to introduce soot into the intake tract, which I can't imagine is at all a good thing.2012 Mazda5 Touring | Finally working on the LTD again!

As I understand it, EGR increases part throttle efficiency due to reduction of pumping losses, in addition to the reduction of combustion temperatures, allowing for more aggressive timing.
That is, on a non-EGR car, when you're cruising at very light throttle, the engine actually has to expend a little energy to draw in the fuel. This energy loss is reduced because the EGR is effectively reducing the vacuum the engine is fighting against, and adding a small amount of inert gas to the mix - not affecting the O2 to gasoline ratio, and actually SLIGHTLY increasing the dynamic compression as well.
I hope my explanation clarified rather than mangled things...
WOT, of course, EGR has no effect one way or the other.1987 Ford LTD Crown Victoria 2-door Coupe - perpetually "sort of" for sale...

The HO swap itself is an mpg booster. The '96 and early '97 ones have the internal egr. If you're lucky enough to find a '97 with the GT40P heads, you have a better head than the plain GT40, granted you'll have to run specific headers to accomodate for the spark plug angle. The explorer swap is like the HO swap with more benefits, though, a little more modification, it's worth it, if you can find everything easily enough.Originally posted by deepsleep View PostComment

Put dual exhaust on it first. Don't need headers or more motor or anything else before it can breathe. The problem with the stock engine exhaust system is not the manifolds, its the small tailpipes and mufflers. If you have single exhaust, thats a really big problem. The factory uprated cars with dual exhaust by 10 hp just because it can breathe.86 Lincoln Town Car (Galactica).

This is very true, when I did my dual exhaust, it was a little more responsive and got like 3mpg more on average than before.Originally posted by gadget73 View PostComment

I've done mustang headers/HO upper/TB/flowmasters/bumped timing to mine, I haven't even tried to guesstimate MPG because I can't keep my foot out of the gas anymore
