I didn't look at that. I seen the speedo was at 145 and i looked back up and we kept going for a few secs and my brother said we hit 150. I didn't pay attention to the tach i was watching the road.

"Does 4:10 gears affect this, make the car faster or slower"
lower the gearing(numerically higher), lower the top speed.

God let's not open this up again, but in a mustang, lower gearing can possibly increase top speed.

I have 4.10s and ran it up to about 150 and seemed to have a little left. But I kept thinking to myself...if I blew a tire out right now, I'm gonna die....so I slowed down. 
I'm with you there.bamagrad03 said:I have 4.10s and ran it up to about 150 and seemed to have a little left. But I kept thinking to myself...if I blew a tire out right now, I'm gonna die....so I slowed down.
I've had my 96 (5sp) up to 135 before 4.10's and it pretty much was all it had.
With gears I can wrap the speedo needle back to the pin so with that crappy speedo gear that is about 10% off and the normal inaccuracy of the speedo I would venture to say I'm at or above 150 actual. As for that age old question do gears slow you down...NO....you run out of engine before you run out of gears unless you are forged and supercharged. Another thing is I'm almost positive autos are governed to 125. At least the 2000 GT I ran against was because 3 different times it was like he hit the brakes at 125.
A governed car will shut down...not hold a steady speed. Almost like you hit the brakes. At 140 you are running out of motor. If your buddy's auto hits 155 then he has had the computer reflashed to remove the governer or has a chip. If I'm wrong I apologize but that is what I have learned in most cars.ridemypony03 said:

Isn't that where the governor is set on GTs that come out with 16" wheels regardless of tranny?
I do not havea reflash or anything. Mustangs, and many other cars for that matter, are ELECTRONICALLY speed limited, not goverened. A governor is a mechanical device that cuts off fuel and the such to slow the car/engine down. I do not know if there is a speed limit difference between autos and 5-speeds, I dont see any reason why there should be but who knows. Usually the facotory sets these limits because of the speed rating of the tires, and can be reflashed to coincide with whatever speed rating your tires are.
