Question Power

I have 2 TJ's both are 4 cyl. One is mine and the other is my wife's. Hers seems to have better throttle response and more power than mine. Her's has 33's and mine has 35's Both have the same gearing. My question is will the 35's make that much of a difference or could there be something in the engine that's effecting the performance.

Thanks
Flash.

35s with the four cylinder engine? you are correct in that is the reason you don't have much power. what is your gear ratio?

if you both have the same gearing the 35's will make a difference. both because of the extra height and of the more mass the little 4 banger has to turn. there are a few engine mods that most will agree are worth it, but to really gain the power back, going to 4.88 or 5.19/5.29/whatever is the way to go.

As an example.. and this will of course differ a bit depending on the make of the tires. My 35's are about 15 lbs more than my 33's. Thus you have 60 lbs more mass that has to be moved. Then add in the height over the 33's and asking your old gears to move this would infact be a difference you could feel. Hm that was a long trip for a simple answer. The best solution would be lower gears, or I have heard that a upgraded flywheel helps on the 4 banger too.
