ive got 33's and i dont even need 1st gear. the 2 years ive owned my jeep ive barely ever used first cept for wheeling and emberassing at stoplights. its to short to fast
oh ya i broke a rear u joint going into 3rd at 4700 rpms that was fun course i had 400 pounds of books in the back and actually got traction
You would not and could not keep up with a (real) cobra, and you could NOT lift a tire with anything even close to a stock drive train.
Tire size numerically effects your final drive ratio. 4.56 gears are usually chosen for 33" tires because it puts your final drive ratio pretty close to stock. This means your gears have mostly compensated for the power loss that comes with putting on bigger tires... mostly. This doesn't take into account weight, rolling resistance, and how many fewer RPM's your tires will do @ X speed because of the increased size.
So: (I'm quoting torque here because HP is pretty much irrelevant to my point
The first SVT Cobra made something like 320ft lbs of torque
96-98 and 99-01 were also somewhere above 300ft lbs
03-04 made something like 390 ft lbs
Your 88 made 220ft lbs at the flywheel when new... 22 years ago.
How many of these can lift a tire stock or even close to stock? None.
How many of these can spin their tires through 4th? Certainly not your Jeep...
How many of these 'stangs can your Jeep keep up with? None. (assuming the driver is somewhat close to maybe considering themselves to be almost competent behind the wheel.)
UNLESS you have some crazy mods you haven't shared with us
And just thinking about all the weird possibilities here: (necessary power mods aside)
Lets say you had some super slick, hard compound tires and actually could spin through to fourth, how would these have enough traction to lift your Jeep?
Ever notice how all those hardcore 1/4 mile guys seem to run big, soft slicks in the rear? You know the ones who actually do lift the front end off the line? They wouldn't if they had normal street tires, but I'm sure they could spin their tires through as many gears as they had. There is a trade off there with traction, you can't really get both.
DISCLAIMER: All the info above is quite possibly a load of crap and is probably going to get picked apart by someone who actually knows what they're talking about.
