What tipped me over the edge to supercharge was at one year's All For Fun event in Leadville, CO. I was trying to keep up on the drive to the trailhead - we were at about 9,000' elevation and our Rubi felt like we were dragging an anchor. Lower elevations weren't quite as bad but the blower has made a huge difference on the highway.

I was one of the unlucky ones. Not only did my EPDA fail twice and was failing for the third time. The precats also burned and clogged the exhaust system. All of this was replaced under warranty but still---- Can't imagine what a turbo would look like with cat crap in its guts.

Here's a video of my Rubi on the dyno with the RIPP.

I don't remember the diameter but it's slightly smaller than the one RIPP normally uses. One of my requirements when I was chatting with RIPP was good performance at high altitudes. Even with the smaller pulley I don't think the engine ever goes above 8-10 pounds of boost (good for engine longevity.)

Bought a spool of stainless wire for the mig. Cut apart and cleaned out the cats. The catalyst medium was melted and had plugged the turbine housing. Runs fine, no MIL but I only drove it for 20 minutes. Time will tell.

Hey @Wood what type of MPG hit did you notice with the Banks and does it require premium fuel?

I have 33's with 4.10 gears on my 04 and got about 13mpg driving out to west Texas this past weekend. The Jeep did okay but last October when I was in Durango I struggled to keep up with a JKU on 37s getting to the trail head.

I am between a LS swap and the Banks. I know John has the RIPP and seen it in action but it seems RIPP doesn't make the TJ/LJ version anymore. Trying to get more real life experience from people who have the Banks.

Thanks.

Chris

The mileage didnít really change much with the 32Ē tires. I could go easy on the highway and get 450 kms to a tank. With the 35ís and stock gearing Iím generally at 1-3 psi at 110 kms/h. It is a bit heavier with the ARB and winch on front, tools and trail spares, and the rear bumper with swing out tire carrier I built. The TT and long arm suspension adds some weight too I guess. I honestly donít know what the mileage is now. I canít seem to drive it without dipping deep into the boost. It always puts a smile on my face. With the BOV spacer it sounds very cool ha ha ha. I have never regretted the banks kit. It is extremely well engineered. Even when the precats melted down the turbine housing caught the chunks and the turbine was unharmed. Was that by design? No idea but like I said, very well engineered. I have to run 91 octane or a bottle of octane boost with cheap gas. With an intercooler and a lighter right foot I would guess that the tendency for spark knock would be reduced but thatís just a theory. As far as performance there is no turbo lag. I have had multiple buddies state a SC is a better way to go until they got behind the wheel. Check the dyno sheets on the banks website, with the kit (not inter cooled) it is making 300 ft pounds below 2000 rpm IIRC. When I get my F100 project running I will likely intercool the LJ. 😜
