2005 TJ Rubicon - Boosted Technologies Supercharger Install

[mlozano]

Hello all. I'm Mariano from Santiago, Chile.

I have a 2005 TJ Rubicon and bought used a Boosted tech supercharger kit.

I`m going to install it without the piggyback (Split Second).
I'm following the Flying Ryan`s recommendations of this post:
https://wranglertjforum.com/threads...n-tuning-rant-from-a-tuners-standpoint.53871/

I already bought SRT4 2 bar MAP Sensor, colder spark plugs, larger ford injectors, AEM Methanol injection kit and have a friend with dinamometer and a lot of experience programming all kind of jeeps with HP Tuners.

Considering I'm not going to use the piggyback, I need help from someone that have done the same with pictures of vacuum and boost hoses and any other advice will be appreciated. (I know that lot of people don`t like this superchargers, but may be i found someone happy with his setup that want to help me and i want to try it.)

Thanks

Mariano

I'll show you how I have mine set up. Not that it's necessarily the best way, I first installed this kit probably 5 years ago and it's been in and out and in different configurations a ton of times. What I can tell you, is it works this way. But really everything should be pretty straight forward. Just think about where your vacuum lines are and move them upstream of the blower. Boost reference obviously down stream of the blower. That's pretty much the gist of it. I also don't know that your supercharger will look exactly like this one. I imagine they pull M90s off a variety of models and years of vehicles and the ports might be in different places but the general positioning should all be the same. Vac side to vac side, boost side to boost side.

There are three vacuum ports on top of the blower. I capped one off. The large center one is into a tee. One side runs to the rear crankcase vent on the valve cover. The other side runs down to the emissions evap solenoid. The small third top port runs into the semi-rigid vac lines along the firewall. There's a 4th vacuum port that comes horizontally off the side of the blower adjacent to the vertical ports. This runs to the brake booster.

The bypass actuator has a single boost line that runs down to the adapter plate. There should be a port there to connect to. You can also see in this photo there are multiple ports on the intake manifold that would have previously been used for the vac lines. Cap ones you don't need, utilize the ones you do. You can see in the bottom of this photo one large horizontal port capped off. Behind that there's small boost reference line. I believe that goes to my meth injection system.

Now this is gnarly and kind of embarrassing but I'll show you. It was supposed to be temporary but it's worked fine so I never got around to making something pretier. Ideally I'd like to make a little aluminum manifold. But this is on the top of the intake manifold towards the rear. There's a larger port, I have that split using whatever I had laying around in my garage. The SRT4 map sensor is shoved into one hose (on the left of the photo), and the AEM boost sensor for the boost gauge is in the other. (on the right)

The late TJ IAT sensor is a plastic press in unit and won't do. The early TJ intake sensor was originally installed in the intake manifold and is metal and threads in. I got one of those and drilled and tapped a home for it on the front of the supercharger adapter bucket. If I recall the wiring reaches here and the the plugs are interchangeable. if anything there might have been a rib on the connector that needed filed down.

You can see it in the first photo as well but bolted to the top of the supercharger is my meth injection solenoid. I have it injecting in the aluminum intake tube right there, it's the black fitting. Ideally it'd be closer to the throttle body. The closer the better. Injecting meth pre-blower helps the blower seal and aids in cooling.

Over on the passenger side looking down you can see the placement of my wideband o2 sensor.

I have a large AEM meth tank installed in the rear on a frame I hacked up that mounts into the factory rear seat bolt holes. Meth pump mounted to the floor with nutserts. Wiring and meth lines run along with the factory harness on the left side to the front.

Thanks again for your help. Here are photos of my parts. It looks pretty the same.
I see that i have both ports on my SC base are plugged. I will buy the fittings to put the bypass actuator line.
For the MAP Sensor, i will temporary install it like you but already bought a throttle body spacer from @Jezza :
https://texasjeepproducts.com/produ...-spacer-with-ports-and-2-bar-map-sensor-mount
There is also on the way auto meter wideband and boost gauges.
I will be posting updates here. Any advice will be really appreciated.

My Jeep is with stock gears and 35x12,5R15 tires. The engine only have Banks TorqueTubes Exhaust Manifold, RAM Air Intake and BBK 62mm Throttle Body. Everything else is stock.
Theese are the results on the dyno, control run prior beginning Supercharger installation. 150.2 HP and 164.4 Lb/Ft Torque. (The previous run showed is with 245/75R17 Tires)

I'm going off of memory.

Vacuum ports in front of compressor
-brake booster
-crankcase vent on rear of valve cover
-emissions
Basically anything that should not be inflated from boost pressure.

Boost ports after compressor
-Throttle body MAP sensor
-Meth/water injection MAP sensor
-Boost gauge
-Split Second MAP sensor

Intake air temp sensor should also be drilled and tapped into the compressor mount.

FWiW, once I got the installation correct, mine has been an invisible system with a smooth seamless transition into boost. I also do not understand what the criticism is of the Split Second controller is or why one would not use it if it is available.

That map sensor mount won't work, you'd be reading vacuum only since it's before the supercharger. You need to read boost, after the blower. MAP = manifold absolute pressure.

JTEC or NGC?

On my '05 the Split Second would not transition smoothly into boost and often run lean. It got worse as it aged, it started going lean in the middle of pulls, and then it stopped working entirely. In addition to that the Boosted Tech guys could never get it to play right with the factory PCM and the whole system would enrich and choke the engine out on the highway.

Piggybacks are always a compromise, imo.

If there is a compromise on mine, I do not recognize what it is.

ouch... I have already ordered the mount... I wonder why they sell it, also the discontinued BANKS turbo kit have similar mount

Do you have the MAP connected in this port?

Does the MAP sensor need to read boost pressure? Does that port receive boost pressure?

They sell that mount because it works with turbos and centrifugal blowers. Those boost the entire intake track, before the throttle body. You're boosting post-tb.

Yes, that's the port I use. But any of the ports on the intake manifold are going to be seeing boost. Think about the basics of what's happening here and this will all make sense.

Thanks for the explanation. I`m not an expert and really appreciate your help!

I don’t recall, JJ - are you running an AFR gauge?

I am. And it moves around!

Yesterday i have started with the installation.
- Bought old style IAT Sensor (Prior 2004) and fittings for boost actuator. Also some rubber caps to cover unused vacuum and boost ports.
- Labeled all hoses to identify after installation.
- Replaced injectors. (Ford F350 V8)
- Bended AC Lines (Need to bend a little more after complete install because they are touching the supercharger)
- Installed supercharger.

Today i will finish install (Change spark plugs, install MAP sensor, install serpentine belt and connect all the hoses).
I'm waiting for the AEM Meth kit (Bought used).

 

[mlozano]

Fwiw, the MAP sensor for the Banks turbo is on a spacer located after the throttle body.

View attachment 578781

…which, as previously mentioned, wouldn’t
work for your build.

Yes... thanks for the pic... i have a pretty paper weight on the way to Chile. .
Finally this is my "Pro MAP Adapter"... a piece of hose with a clamp.

 

[mlozano]

Today i finished the installation...

I had to buy a 90mm idler pulley (the previous owner of the supercharger lost the one that came with the kit). Fortunate i found one from a dodge durango.
Also bought an AEM 2.5" air filter that fits the aluminium tube from boosted tech. Covered the tube with fiberglass heat wrap, and it started!!

Now i have to go to the dyno and make the proper tunning (I have to wait for next week)

I´ll let you all know when i test it and how are the results. Thanks all for the help.

Regards

Mariano

Another question... Anyone have installed the Methanol tank and pump under the hood?. I'm thinking to put it in this location. What do you think?

Yes, I ran mine under that hood with no issues and was happy with the placement. Also ran AEM's filter and solenoid to help ensure all would be good.

Ignore the black boost controller sensor on the support behind the solenoid. I have 90* fittings for the line near the fender but didn't need it. AEM's tubing was more pliable than the stuff I got on Amazon.

Edit: A different angle (you would have to run it a little more forward due to the tank placement). Your location is fine other than not being as easy to access with the tank...if that matters. I had zero maintenance issues in the few months of running the set up.

Thanks.

Where do you have the tank?
