Question about 5.0 motor in 86 GT.

eeh102582 · 04-02-2004, 12:22 PM

Hey guys i bought this car from my cousin and he had this car since 88 he bought it off some and my cousin did know anything about it, HERE MY QUESTION, i been seeing what evey body has been saying about how much HP these motor should make with mild work, and there puting like 270 to 300 thats with alot of aftermarkets, so i took my car to get a dyno, now its an 86 GTHO motor, the first place i took it to i got 280 on the dyno so about 5 miles down the road i took to another guy that i know and on his machine i got 282, now he says that it might have some work done, he says it looks like it was taken apart because there is the orange rubber gaskets used to seal everything, ford uses cork, IS THIS CORRECT.
thanks alot

If you are putting down 280rwhp then something has been done.

eeh102582 · 04-02-2004, 10:19 PM

anybody else

Something has been done for that. Stock 1986 Mustang HO 5.0 motor makes 200hp and 285 lb/ft of torque. (I believe thats at the flywheel, not at the rear wheels).

429mustang · 04-03-2004, 12:11 PM

280 at the wheels is pretty tough, do you have any pics of the engine you could post? Most of the works probably inside the motor though, is the intake/heads still stock?

ponyexpress289 · 04-03-2004, 12:19 PM

holy moly 280hp is outrageous !!!!!!!!!!!!!!!!! .......maybe ..... i dunno

sombody must have put in an ls1

There should be obvious changes under the hood for an engine putting out that much power.
Different heads, intakes and headers would be some of the obvious things you would notice.
Take it to the track and see what it runs. You'll find out for sure if work has been done or not.

Dark_5.0 · 04-03-2004, 05:50 PM

It has some pretty serious mods to put down those numbers. The changed should be real obvious.

hey guys the heads i believe are stock, the intake is stock, the only thing i did was take off the somg and ac pulleys and got a shorter belt bbk long tube headers, blaster 3 coil, taloyor race wires, and a bbk cold air intake. thats it, should the gaskets on everything be orange from factory? thanks

82 GT · 04-04-2004, 12:03 PM

OK..I'm going to be the first to say it.....something does not quit add up here. Either there is more work done to that engine that you can't see or those dyno numbers were grossly inflated.
You don't get those kinds of dyno numbers with those simple mods........I'm sorry....you just don't
Take it to the track and let us know what the MPH was through the traps.

eeh102582 · 04-04-2004, 03:17 PM

hey guys i will got the track asap, im still wondering what the stock gasket sets look like, i thought the stock are cork? mine are orange. could that be a possiblity that the motor was taped into,
Ernie

82 GT · 04-04-2004, 08:33 PM

Hmm...I'll look at my gaskets on my "88 GT tomorrow. That engine, I know, is bone stock.
I don't think they are cork though...they're rubber but I don't remember what color.

lx mike · 04-04-2004, 09:00 PM

no way that engine is making 280 rwhp with stock heads and intake. is it a cobra intake? ported heads? diff cam?

like you said alot of cars are making 270-300 with alot of aftermarket parts and you doing it with stock parts?? there more to that engine than you know or are telling most stock 5.0s dyno around 180-190 rwhp. with a cobra intake, bigger mass air, 65 mm t.b and flowmaster exhaust i dyno'd 235 rwhp.

Dark_5.0 · 04-05-2004, 12:19 AM

Post a pic of your motor please.

I want to see it.

eeh102582 · 04-05-2004, 10:54 AM

hey guys i will get a pic on here soon.
a buddy of mine had a G-TECH pro comp, so i though i would give it a try before he left the HP from that thing said 283 and i did a 3 runs with it just to get a 1/4 time and speed, and i got a 12.64 on the first run a 12.58 then a 12.49 on the last the top speed started 105 to 111, next time i see him i will do some other stuff with it. im also going to take the car to another place to get it dyno on it and the place is call Mr mustang, so i will post a pic and let you guy know what happens. thank agiain

sedanman · 04-05-2004, 07:10 PM

Something is not right. The heads either are ported to crazyness (like R/S cars) or it has GT40 irons on it. Does it lope? It has to have a cam to make that power.

Dark_5.0 · 04-05-2004, 10:20 PM

People do hit 300rwhp with the stock cam and 1.7's.

I just cant imagine making 280RWHP with the stock headers and intake manifold.

People can hit 300rwhp with one of these given parts but stock heads, cam, intake and headers that I want to see.
