I hate those indecisive pricks.

Oh wait; I am one of those indecisive pricks.

Well, I MIGHT be wheeling Sunday the 8th now…

I got a wild hair and decided it was time to start the supercharger install. I have been putting it off and putting it off. I keep tell myself “I don’t want to miss the next run so I will do the install AFTER the next run.” Well three next runs later I have decided I may have to miss one to get this done. I did the entire tear down and clean up Sunday evening, even got the fuel pump in. I will defiantly have the supercharger installed but if I run into any problems or have a missing part I don’t know if I will be able to get it done. I also have to factor in some dyno tuning time.

Either way I will be there on the 7th for the race. See you there.

can't wait to see it in action. I thought you were competeing on the 7th

I’m not competing as a driver/co-driver. Charlie Melchner has asked me to drive the chase truck at the KOH. We are using the Raush Creek race as a pre run and pit crew organizer for February. Bill Ansell (BillaVista from Pirate) is Charlie’s Co-driver and the rest of the Canadians will be coming down as well.

oh ok. that's cool

Well are you done yet

On TV they put those superchargers on in a half hour & dyno them

Supercharger is on and it runs!

sweet rig ,let us know how many more horses it gave you and total. if you do a dyno.

Pics , video , sound come on your killing me!!!!!!

It's going to the dyno shop the week after Thanksgiving. I'll be down in Shreveport, LA for work Mon-Wed, then the holidays. It runs at low RPMs just fine. The computer needs to be retuned before it will run right at high RPMs. I'll try to keep everyone
updated.

Lets try this.

Thats sweet as hell, Maybe those Maxxis will clean out little better now

The jeep is headed to the dyno shop tomorrow for the computer tune with the supercharger.

Rob, no need to worry about cleaning out the Creepy Crawlers when it's got a set of red label sticky BFG Krawlers ready to go on it.

Sweeeeeeeeeeeeeeeeeeeeeeeeeet...this rig is gonna be tough to stop!

The finial numbers are in.

--------------------------------------------------------------------------------

235.6 Hp and 321.2 lb-ft of torque.
Base was 131.8 Hp and 184.9 lb-ft.

That’s 103.8 Hp and 136.3 lb-ft gained.

Yes that is the supercharger you hear screaming not the power steering pump! The hardest/longest pull showed the rear wheels spinning 160 MPH!

Some interesting lessons learned:

1. There is virtually zero intake tube. The filter attaches directly to the MAF sensor so the fan from the radiator and the fan on the tranny cooler were really screwing with the sensor. We rolled a sheet of cardboard around the filter to shield it and it made a huge difference. I’ll have to fab up n aluminum shield for it.

2. The driver’s side exhaust tube runs around the front of the motor and meets the passengers side tube right about where the engine and tranny mate up. The passenger’s side O2 senor is getting a turbulent flow from the driver’s side and is trying to constantly adjust so it throws it’s self into a constant loop of catch up and over compensate. It really screws with the system. The tuner made that O2 sensor a pulse reading type instead of a cumulative reading style and it seemed to help. I need to rework the exhaust a little to make where the two sides merge into one pipe about 18 inches from the passenger side sensor.

3. It’s pumping WAY more boost than it really needs at high RPMs. As in like 13.1 PSI!!! The big truck lower pulley really makes that thing scream. It’s tuned to be relatively safe for now but Ted was saying we could lower the boost and put more timing into it and we should get similar hp and torque numbers.

4. The belt already likes walk off the tensioner pulley. Ted was telling me there was and update to this kit because under high loads the bracket would flex and allow the belt to walk. We agreed that with 13 psi it justified adding the extra support bracket. Its on order.

nice ,nice ,jeep

Thats a pretty impresive gain now all you have to do is you that skinny pedal on the trail
