Jeep highway hill climb.

2008 Jeep Wrangler JK Rubicon Unlimited 35" tires, 5:13 gears, Automatic, stock 3.8L V6 making the climb from Silverthorn, Colorado to the tunnel. 60mph road, 8700 to 11,000 foot climb. NEEDS more power!!!!


Going to try to upload a better quality video that will make the tach and speedo more viewable on youtube.

Did you recalibrate your computer for your tires and gear using something like a superchips flashpaq? The flashpaq isn't the end all be all but it'll get your 24 extra horsepower and 11 ft'/lbs of torque and allow your computer to set the shift points correctly for your 35s and 5.13s.

Yep. Has had an AEV Procal on it since the first day of lift.

Ouch that's gotta be real hard on the jeep. I would have gave up a bit of speed to try to save the engine and transmission a bit. That can't be any good for the engine spinning at 5000RPM for minutes. I know for a while they had issues with the transmissions overheating and catching fire ...

I know the 3.8 is no powerhouse - I also have a 6 speed 08 Rubicon and it can't get out of its own way compared to the 4.0.

I almost did a hemi conversion this year. AEV has an office nearby and I was going to have them do the welding and I was going to do everything else myself. But even doing it yourself it's about a $10,000 investment.

I wouldn't bother with a RIPP supercharger. On that climb it would have gotten so heat soaked that you'd have been detonating like crazy. You'd have needed pistons after a full throttle run under that much load for long.

I've got the same problem with my TJ with 33's. It's the gearing. You gotta re-gear it after going to big tires.
