sounds pretty dam low to me, especially the tq

[HMUSN]

yea there is something wrong there man

[BWAL]

that doesn't sound right to me.. some other guy had his stock 5.0 dynoed and it was like 192rwhp and i forgot what the torque was

it was 91cobra5.0 and he put down


91 mustang
266 ftlbs 191 hp (15.138 @92.91)

almost stock and alot higher elevation, and i doubt his power topped off at 3500

[shadowgames81]

stock at the motor should be around 215-225 and w/ that list of mods obviously more. I think that is quite a bit lower than I'd expect.

it was on a dyno, its not gona read 215-225 at the wheels

[shadowgames81]

I know that.....I said at the motor didn't I??? W/ the parasitic loss through the drivetrain it should still be more.

[89lx]

any ideas where i am losing the power?

[shadowgames81]

compression check??

[JBIGBOOTSY]

It depends on the chasis dyno, take it somewhere else and the power may go up.

That is really low.

there is something not working there.

yea but im at like 6000 ft ABOVE sea level

[89lx]

what kinda numbers should i be getting?

[89lx]

i know its not the problem but i changed the fuel filter it was pretty choked up tomorrow night if all goes well i am going to check the plugs and compression, fuel pressure and clean the injectors, and make sure my tps is reading right. any other things i should check?

[95StangMX]

I am not sure on the HP but 3500 seems really low for peak.....unless its diesel...j/k ....I would say maybe a compression test is needed...and maybe check the timing ....but if they dynoed it they should have checked that i would think....who knows....

In the area of 200hp at the wheels for the modifications you have. Possibly a bit higher or lower depending on the type of dyno, weather conditions, etc.

[89lx]

i checked the fuel pressure its 32 psi running, compression is 150psi on all cyl's, cleaned the injectors, changed the fuel filter, found one bad plug, checked timing. where do i go now ? it had code 81, 82, 85, 84.... i have the egr deleted.
