Fastest Factory 5.0?

FastDriver said:

My memory was getting a little fuzzy on the details so I had to do a little bit of research of my own. This site has been around for a long time, now. This is an excellent source regarding changes in 5.0 liter GT mustangs from year to year... the 1993 year discusses the revisions in-depth and the new rating system...www.mustanggt.org

1/8 mile track... Made three runs. Don't have the timeslip in front of me, but my best of the night was an 8.0@92.x mph with a 2.0x 60' on street radials, which means half-throttle in first and second.

I'm running an incon TT kit with 9.5 psi intercooled, with GT40X heads, GT40 intake, and 3.73 gears, on 17" cobra R wheels.

I do have an FTI combo .... That's another engine.

I mentioned the wreck in one of the PMs I sent you...

I believe several cobra owners claimed their bone-stock cobras went mid 13s. One that I remember in particular said he went 13.6. I doubt the threads are still online, but I'll look around for them.

High 13's here. Though it took a few low 14's due to my skill level.

But they also have a poor intake design because ford had to shorten the engine hieght to fit under the SN95's hood. That cost a few ponies there. Let's also not forget the horrendous pinging computer setup as ford struggled to meet emmissions regs the last few years of the 5.0. Only reason it survived int he explorer/mountaineer was because SUV's didn't wally have strict standards until a couple years ago.

Let's look at the 93-95 Cobra motor. It's rated at 235-240HP. We all know that's crap as in reality they are putting down numbers which suggest 270ish HP at the flywheel. If you notice, the same exact GT-40 crate motor in the ford motorsport catalog boasts 320HP. How did the motor loose 50HP?? A poor cam and computer to try to make the car pass the sniffer. The 93-95 Cobras were really detuned if anything.

Our little 5.0 is a dirty motor

I'll also chime in and say the book was wrong.

It state NO CHANGES made throughout the 87-93 model year.

Let's not forget addition of mass air, several cam changes to quiet the drivetrain and meet emmissions, an H-pipe change, several stock muffler changes (i beleive '87 AOD's were rated at 5HP less because of the mufflers) and not ot mention a couple of different computer tunes.

The 5.0 engine changed quite a bit...and sadly, those changes were mostly for the increase emmission standards that eventually killed the 5.0 in 1995 (in addition to Ford wanting it's flagship car to carry it's new flagship motor design)

So yeah. i also say the book is wrong.

i wanna clerify something. the popular 225hp that all 87-93 stangs got, means 225rwhp. since when does a state of the art electonic fuel injected 302 v8 with forged pistons only put out 180rwhp? thats wrong. the popular 5.0 87-93 makes around 240 crank hp. whlie the 93 cobra makes just about 305 crank hp. there isn't a 30% power loss thru the drivetrain, that is wayy too much. its more like 6-8%. anyone with a brain would refuse to believe that gt40 heads which are like 35-40hp, and 1.7 roller rockers, and bigger tb and a maf, adds only 10rwhp like ford claims 235 for the cobra and 225 for the regular 5.0. if ford had done it the right way the cobra would ahve advertised 280 not 235. and that rating is rwhp not crank hp.
