3 inch?
Reply #9 –
don't mess with the 3inch stuff unless
you are going with 400+ small block
you are going to spend most of the time in the7,000+ rpm range
you got some great big blower , super charger that pushing 20+psi to the engine .
if not it just a waste of time and moneyand if your going to do it.spend the extra money and do it mandrel-bent pipes all the way out the back..
in my street/strip 1986 fox body with carb 1969 built 351W4V and 5 speed tranny. it makes around 425HP at the wheels at 6500 RPM.
i use 1994/95 mustang style 1-5/8 equal lenght shorty and mandrel-bent 2-1/2 H-PIPE and flow master lers with mandrel-bent 2-1/2 gt style tail pipes .if i put the long tubes header back on the the 86 .the hp would raise to 475 but it shows on the dyno that i would loose 29ftlbs of torque in the below 4500 rpm range plus they hang down lower than the body .so i would loose the sleeper look.
on my 1980 fairmont wagon i had. i installed a COMPLETE EFI 1995 5.0 -5 speed, four wheel disc brake cobra drive train with some GT40 PARTS for fun. i had 1994/95 mustang standard BBK chrome shorty with the mandrel-bent 2-1/2 H-PIPE and summit dynomax super turbo ler and mandrel-bent 2-1/2 mustang LX tail pipes. IT made 275 hp at the wheel at 5800rpms. talk about the greatest sleeper.
both cars i drove on the streat and at the strip, run on 88octane pump gas. they idle fine at the stop lights, when it put the pedal to the floor, they have no problem getting to the higher rpms.
the wagon:burnout: was the funniest to drive of the two ON THE STREET.
