Engine Performance & Gas Mileage - Can You Assist Me?
I got 21.1 on a 1500+ mile trip where most of the highway driving was well
above 55mph, 10 days was camping off-road in Canada.

Now you are trying to give performance advise on a 4.0? Your other lunatic posts are also out there to quote from. You have proven beyond any reasonable doubt that you are totally insane and know nothing about a 'part time' 4x4 so unless you want flames every time, stop dogging my posts.

The troll in you is back!! I have owned well over a dozen 4x4's of all flavors and with 4cyl thru v8 too in the last 36 years or so and currently own 3 of them and my comments are driven by years of experiance not ego like yours. I have never said that I stopped on highway to engage 4x4 drive but I may have said you are a fool about your recommandations on the proepr use of 4x4 drive including at highway speeds. Also the principle behind performance gains are the same with all non super charged gas motors. (BTW, I have owned a 4x4 Jeep with a 258 too in years past) A gas motor is a heat engine driven by hot expanding gas (kind like you are at times) and the piston captures this and couples it to crankshaft. The engine is tuned to expect a certain amount of back pressure when it operates and the cam is timed to this. When you chop off the exhaust, the gas escapes cylinder too quickly and less of it is transfered to crank and this effect is most noticable below 3000 RPM or so. At higher RPM the duration of valve opening is reduced (relative to real time) and this loss of back pressure is not a problem most of times then. Also at lower RPMs during overlap some fuel mixture may be lost out of exhuast valve when there is no back pressure reducing MPG potentail. If you want a engine with good low RPM torque 4,6 or V8, keep exhaust stock. If you have ego problems like Mike here and you like to brag about spinning wheels on 4x4 drive on hard pavement and blow off a lot of noise and hot air take his advise. WHen you add a turbo charger the back pressure rules change because reduced back press increase turbo efficency. ----------------- TheSnoMan.com |

Your bull**** won't be put up with for long in this group, neither will your 'play' with words. Instead of spouting off bull**** about stuff you don't know, why don't you take your 'so called' vast experience with J10's and answer those folks with troubles? I'll bet you can't even help the poor person trying to buy one asking for help here who doesn't know how to shift one eh? Oh, my sig line photo albums are of Jeep off road runs consisting of folks 'from this newsgroup'! Jerk.
