5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
I have an 89' LX 5.0. It has a Typhoon upper and lower intake, 80 MM throttle body, 75 MM mass air, E-303 cam, 24lb/hr injectors, MSD billet distributor, 351W heads, underdrive pullies, long tube headers, 3:73. This thing seems to have no power!! It won't even barley chirp 2nd!!! What gives?
80mm t/b. Why? 65-70 at the most. Oh and you know the opening on the intake is only 70mm right? Unless you had it opened up. Still, the 80mm is def hurting you
Did it just all of a sudden lose power or did it have no power from the start of the setup? What is your timing at? Plug gap? Stock ignition other than the dizzy? Fuel pump? Fuel pressure?
It's a 5 speed...I will change that 80mm TB to a 65-70. Thanks for the info guys.
The 80mm TB is not what's causing the problem, instead of spending $$ in replacements that will not solve the condition, suggest to do some tests first..... engine vacuum output check, run the self tests, verify initial advance, etc, etc
