Just thought I'd put up a pic of my coupe. I've done a 12.54@106 last spring and havent gotten to the track yet this year - I need to do that soon! ! For a more detailed 'mod list', check out my rinky-dink webpage!

Welcome to the board.....

Nice looking 'stang, seems to be running good times too.

Here is a pic of my 'fair weather' toy, the 1989 LX Hatch..
It's running low 12's right now, and I still drive it on the
streets during the fair weather months.

Nice cars, both of them. Miss5.0 I have one question though. Is that 106mph a little low for 12's or not? It kind of confuses me cause one of the fellow Probe owners is runnin a 13.8 @ 106mph. I just find it odd for both to have the same trap speed, but be over a second aprt in the 1/4. I'm just curious.

Actually 106 MPH sounds about right for a car running in the mid 12's.

I'm running right around 110 MPH at 12.2 seconds. That is with about
335 RWHP (close to 370 - 375 Flywheel Horsepower).

To me 106 MPH seems very fast for only running 13.8 in the quarter..
A normal car running those times would probably see mile per hour
figures at around 98 at the end of the quarter..

Really. Do you think it's because of gearing. Probes have very short gears. At 60mph I'm running at 3k rpms, maybe that's why. My friend's '95 MGT even with his 410's in it is still at 2k at 60mph, when he's in overdrive. I think the Mustangs gears are a litle taller than the Probes. Maybe that's it. A stock PGT will run anywhere from 15.3 - 15.7 @ anywhere from 89mph-91mph depending on driver. What do you think?

I am with P71Times2 on this, I think 106 mph is about right. You do often see mid-12 second stangs with traps between 110-120 mph's, I think those are basically stock mustangs with NOS(?). Just my opinion and that's what I see around Austin. (Mines naturally asper.) Also may help that with me in it, my car only weighs 2900 lbs. Apparently a 280 hp car weighing 2900# can haul ;-)

Well, I'll admit that I don't know much about Probes, but it could have something
to do with the gearing...

The quarter mile "Mile Per Hour" figure is a true figure of the horsepower you are
pulling. But if you are hitting 110 MPH the times should be much quicker than
high 13's..

My 'stang is running a Detroit Locker rear with 3.73 gears, along with a T5
tranny with a 3.35 first gear ratio. The engine is N/A, and makes power up
to 6,500 RPM, compared to a 'stock' 5.0L mustang which tops out in the
5,400 - 5,500 RPM range. Even so I have to be very careful of the diameter
of the rear tires I run at the track. You want to cross the finish line right at
in your upper power range, but you don't ever want to have to shift into
"overdrive" while making the run..

Traction can also make a big difference in your quarter mile times. I run a
highly modified suspension (frame supports, steeda upper/lower control arms,
rear support, tokico 5 way drag struts up front and 5 way shocks in the rear,
plus a few other little things). Even so, with wide 50 series 16" street tires
I can smoke them in first, second, and most of third on full throttle runs...
It looks impressive, but it will kill your ET's.. :)
