New Ring and Pinion Set OR Edge System Intake-Throttle Body- Control set
I have a 2000 TJ Sahara manual transmission. Good shape, used mostly on the
road for daily driver. But for hunting and looks I got a 4 inch lift, front and rear TrueTracs, and tires went up to 33s. It looks good, drives well on road, and gets me in and out of the hunting area with ease. However, 5th gear lags too much to use on the road. Engine is the 4.0L. I know I can change the ring and pinion set front and rear, but I'd like your thoughts on the Edge System for a HP increase instead. One downside of the Edge System is that my high lift jack is under the hood and I think the intake will be in the way of the jack. I have a new Warn tire carrier and bumper which can't accommodate the jack and I really don't want to change it. So, I'll have to find some way to carry the jack. Masnor@cox.net |

Anybody who thinks some snake oil cure is going to add enough HP and torque to overcome the increased rolling diameter 33 inch tires is seriously deluded. Even with stock suspension the use of 5th gear is iffy unless you have a downgrade or one heck of a tail wind. The 4.0, especially the later MOPAR versions, are pretty close to optimum on the intake side - you would do better by looking a better exhaust headers and opening up the exhaust. -- Will Honea |

There is only one REAL cure for lifts and big tires and it is called GEARS. There are many that think they can "fix"it with a intake or exhaust or a chip but you cannot and are fooling yourself. Think of deeper gears as a bigger longer lever or pry bar as it takes less input force to move a load with a bigger lever and it takes less drive dtrain torque to move vehicle with deeper gears. Your engine may be rated at around 190 HP but at say 2000 RPM it is only making about 75 HP (HP is torque x RPM divided by 5252) and when you lift it and install bigger tires you increase HP requirements due to increased drag while loweringr RPM so there is less power availble to overcome this. Installing deeper gears rasies engine RPM in any given gear at any given speed and so there is more power avaible to overcome load. No snake oil add on is going to fix this but there is a few in this NG that would lead you to believe that it is not a problem and that tall gears and loss of proper usage of 5th is just fine. Sad part is that not only do you loose 5th but you also loose effective pulling power in every other gear too unless you regear it. No add on short of a supercharger is going to give you the torque you need to overcome this without a gear change but then you are straining engine and drivetrain more doing so. Best real solution here is gears. Below is a link for a axle ratio and tire size calculator if you want to play with some numbers, Also remember that you just do not want to match your same effective ratio because a lifted 4x4 has more drag so you want to actually gear a little deeper than just a equivlent. http://www.snoman.com/HTML/axlecalc_5a.html ----------------- TheSnoMan.com |

Gears are the only way to properly fix it and restore the peformance you
remember. I'd like to see a picture of the hi-lift mounted under the hood, if you dont mind.
