If i'm making basic upgrades for exhaust and intake and pulleys; should i go for 3.73 or 4.10? Plan on making other upgrades in the future.

 

What trans is in your car and what mods do you plan on in the future?

 

Stock 5-speed with short throw shifter; eventually a supercharger and headers

 

Hands down FRPP 4.10's then.

 

I hear that 4.10 gears are too much for supercharged mustang?

 

oh my god i love that chick dude. as for the 4.10 gears it is a perfect gear for our 5 speed tranny. but opinions are like ********, everyone has one. hands down one of the best mods i did

 

Only if you plan on running over 130 mph in the 1/4...

 

why is that mod, last time i went the the track which was a while ago and a different set up, i was running 125 with no probs

 

And you should. The 4.10's gears are good to about 130 mph before they will run out. If you plan to go faster than 130, then you'll need to drop down to make it pass the 1000'.

Remember though that at 130 mph with most set-ups on our cars - you are deep in the 10's even knocking on the door of the 9's so it's doubtful most guys will ever have issues with 4.10's.

Hell, if I was running under 125 mph, I would use 4.30's...

 

yea, i thought you meant as in general you woukld run out of gear. i havent had any probs running terminators on the interstate, with the speedo peegeg at 140. i was in 5th but still moving, and that something i would never recomend anyone doing, i wont. once was enough
