Prodigy Performance 3.6 Turbo DIY Install

[NOLAjeeper]

When Prodigy sent me the parts to hook up the PCV hose with a check valve, the instructions had me keep the road draft tube hooked up to the "make up air" vent on the engine. This was unacceptable, because air gets sucked INTO the engine through that tube now! That just seemed like a disaster waiting to happen (tires kicking up dust under the vehicle where the end of the tube is, submerging the tube in water, etc). I immediately ran out to an auto parts store and found a breather filter that I was able to rig up satisfactorily to the original make up air hose, but it was kinda ugly and temporary, so i didn't show it off. Prodigy told me at the time that they were still working on finalizing their solution to the make-up air side of the PCV system.

I have since received a small breather filter (smaller than the hideous monstrosity I had rigged up) from Prodigy with a hose coupler that I believe is intended to be used to attach the filter to the end of the rubber hose that had previously connected to the air filter box. That just so happens to be the same curvy rubber hose that I sacrificed to modify the PCV hose (in the link at the beginning of this post) so I could add the check valve into the system while retaining an OEM look with the formed plastic hose.



Jeff, that breather is hooked up to the hose that is attached on the drive side of the engine, that vents out to the atmosphere and hangs above the transmission? Thats that hose right?

Since the previous few posts didn't have many pictures, here's what it currently looks like under my hood. Feel free to drool

I talked to Prodigy today. They are still testing some ideas for crankcase ventilation, so the stuff I have posted related to crankcase ventilation is likely not final.

Also, they put stage 2 on a dyno recently. Stage 2 is going to blow away the superchargers for sure (at least in the upper RPMs). Can't wait to see JeepLab's dyno chart comparison

Pickles - question for you as I read through your install process and drool over the pictures. Do you think that, after removal of the OEM airbox and install of the cone type filter, that there is room for a winch solenoid box on the firewall side and slightly above the K&N filter?

I've been struggling for months on exactly where to remote mount my winch's solenoid box and have yet to find a solution under the hood. It looks like you may have room in there. It could impede airflow but methinks not!?

[UselessPickles]

Do you know the dimensions of the solenoid box? If so, then I can measure.

Btw. The filter is not a K&N. It's a non branded dry filter. That's just a K&N water repellant pre filter wrap I added as a precaution to protect from water/mud splashing up from below. The bonus side effect is it makes the filter appear to be black and blend in more

I'll have to get some measurements. Its an ENGO unit from my E9000. Its pretty big.. 9 long, 6 deep, maybe 4 tall.

Started a thread on it, a ways back here:

There *might* be enough room if you can get creative with a mounting plate/bracket. The air filter is about 4 inches below the top of the, and the compressor outlet of the turbo is about 8 inches away from the side of the engine compartment. I forgot to measure from the fuse box forward to the power steering fluid bottle. There might be enough room there for the length of the box.

I took the stock exhaust pipes and catalytic converters to a scrap yard today. I only got $40 for the cats, and they said the pipes were essentially worthless in that small amount. At least they'll get recycled.

I feel like I got ripped off a bit, but I also didn't want to use more gas driving around to other scrap yards to price-shop. You can't just call around to get values of this stuff. they have to inspect the cats in person. Which means you need to cut the pipes off the catalytic converter section before you take them in so that they can actually visually inspect the catalyst material. A sawzall and an angle grinder got the job done for me.

Speaking of using gas, the best part of the trip was that I traveled 25 miles with less than a gallon of fuel. I reset my dashboard mpg reading before I left my house. When I parked at the scrap yard, it was at 28.0 mpg! It was some unusually gentle driving though, because I had the pipes in the back and didn't want them sliding around.

I'm surprised you didn't get more for the catalytic converters. Beats me! I think I'll keep mine for a while based on your experience. I know you're not supposed to sell them but if a buddy of mine needs one for some reason, I'd rather have mine to give away vice the price of new.

I'm not sure I'm seeing the same MPG increase. If anything I'm about the same so far on the highway. I'll have to do better in calculating the actual MPG but I'm on 37s and 4.88 gears. This would be ridiculously rocket fast if I had the stock rubicon tires or smaller. I just burped the coolant system and getting ready to go fill-er-up with some 93!

I'm very curious to hear if you end up with any MPG gains. I'm still dumb-founded when people say they get MPG gains after adding a turbo. Let's see, put in a device that pumps in more air, so you can dump in more gas to make a bigger explosion in the cylinder... Result... More fuel efficiency... Umm, something seems wrong with this equation. My only explanation is that Prodigy actually did a better job on the computer program than Chrysler did. Ohh, I guess it would help if the Cat converter and other EPA stuff was removed ;-)

Either way, Pickle, that awesome that you're getting 28 MPG (or say 25 MPG if you weren't driving like a grandma.) Right now, with 35" tires, top off and no doors, I'm getting around 15mpg average in city driving. If I go out on the highway, I bump allllll the way up to 16mpg.
