whats the cheapest and easiest hp gains on a mustang 5.0ho 87-89? any freebies?

93CobraR · 03-21-2001, 09:43 PM

Timing, air silincer. The first mod any 5.0 should have is by far gears...

anything else? pulleys?
whats an air silincer?
moving to the top. theres got to be some easy stuff that can be done on minimal cash.

blue00gt · 03-22-2001, 12:32 PM

pulleys give the most bang for the buck.

fiveohpatrol · 03-22-2001, 01:11 PM

yes underdrives are a very good gain for the money, the air silencer is inside the passenger side fender behind the air cleaner, it is supposed to quiet the incoming air but i didnt notice any difference when i took mine out, just take off the air cleaner assembly and there should be about 3 screws hodling it in there, remove those and pull the silencer out through the bottom, you will also want to advance your timing to about 14 degrees or so, the exhaust system is also very restrictive in these things, get an offroad h-pipe (little over $100) and you'll feel a noticable gain, then do the rest of the exhaust as money permits,

If you have to pass emmissions, get a high flow cat H-pipe instead of the offroad, it'll give you more torque regardless. The first thing you should do is take out the air silencer though. Then get some better gears, 3.55 or 3.73, and underdrive pulleys.

recovering5.0L · 03-22-2001, 09:37 PM

i really dont want to put the lower gears in, i like the cruising speed so im looking for making it up in the motor. how much compression am i running , and what hp on a stock 87 gt motor with headers

dinomite · 03-22-2001, 10:07 PM

The first thing that we should have asked: How fast do you want to spend? In other words, would you be up for putting a few $1000 (er whatever the equivelant is in the Home Country) into your motor and then another 1k in your tranny to support that? Or are you looking for simpler things? The people here can help you plan out whatever you want. :-)

82 GT · 03-22-2001, 10:38 PM

recovering5.0L, the factory HP rating for an '87 GT is 225 with 300 ft./lbs of torque.
Someome correct me if I am wrong but I think the compression is 9.2:1

15 degrees timing is the best gain for no buck!

xjinlongx · 03-23-2001, 12:35 AM

hey heres one that always gets over looked. switch to an electric fan set up. the loss of the drag from the fan on the crank can be good for an easy 10 hp on relatively stock car. flax-a-lite makes a kit for specifically for the mustang...has a pricetag of just under $200 from summit

StreetStang007 · 03-23-2001, 10:09 AM

Bypass your coolent line on your egr plate all you do is connect the rubber hoses that run into the egr plate it runs hot coolent though there it will help

StreetStang007 · 03-23-2001, 10:10 AM

oo yea if no emissions take off your smog pump and get the shorter belt this will also free up some poneys

smog pump?? what is that and where is it. and where is my egr coolant? im used to working on iron that doesent have all this stuff on it. i am a newbie on adjusting and tuning fuel injected engines.

BUY a CHILTON'S

82 GT · 03-23-2001, 10:14 PM

I don't know for sure where the EGR coolant line is but I do know where the smog pump is.
If you are looking at the engine from outside the car, the smog pump is located under the alternator. Not directly under but you know what I mean.
Or this: Locate the water pump, alternator, and power steering pump and the crankshaft pully and whatever is left is the smog pump.

The lines that are described above are on the EGR spacer which is right between the throttle body and upper intake. You will se two rubber lines going into each side of it. Remove the lines, get a connector, and connect the 2 lines together. Now there will be no hot coolant flowing through the EGR which will result in a cooler intake charge.
The electric fan is not worth as much as you think from what I've hear. It only has negative effects below 3000rpm's, above that the clutches release and the fan free wheels without drag on the motor. At the strip your RPM's shouldn't fall this low anyway, so you won't see much if anything at all at the strip- but this is just what I've been told, I may be wrong. I do believe that an electric fan is still a good idea anyway. If you get one and plan on running at the strip, I would also hook it up so that it could be turned on while the motor is off- this will draw cool air through the radiator cooling the fluid in it, plus it will blow air over the motor. This will benefit you at thr track.
JFYI- Pulleys, 14* timing, offroad X pipe, mufflers, HD clutch, and 3.73's knocked 7 tenths from my ET and I gained 4.89mph on street tires.
