Here you go

 

Awesome!

Bet you're gonna get some funny looks with that little whistle

 

Yah, I'm pretty happy.

The IAT sensor was moved from manifold adapter to intake runner #1. WOT temps dropped from 260 degrees to 168 degrees at WOT. Maybe due to lower engine temps and ECU not retarding spark due to knock and high temps. But the manifold adapter is pretty restrictive. SC is probably pushing 12 or better psi just to get 6 psi after adapter.

Need to get a retune to adjust some things after IAT sensor relocation and loss of knock.

Max knock count before new bearings at WOT was 29. WOT max knock count now was 14 and that was during a transmission shift and went back down after shift.

75 degrees outside and a 168 degree intake temp is pretty good. Once winter gets here those will drop significantlly. 80% of my driving is in the winter for this excursion. Not sure I need a intercooler or water meth, we will see.

 

Very cool. I'm officially jealous...

 

Awesome work, glad you got the knock sorted out.

 

I have been trying to lower the intake charge.

One of the things I have noticed is the supercharger makes contact with the hood insulation, when hood is closed. It's enough that you can see the imprint of the supercharger on the insulation when hood is open. I'm thinking this is causing some heat build up in head unit.

Anyone know of a good hood that will alow some air to flow buy the supercharger and give me a few inches of clearance between supercharger and hood?

 

I know Cervinis makes a cowl hood for these things, not sure if it'll add clearance where you need it though. I think I've seen one on LMC as well.

 

Here are my thoughts on my KB TS6800 kit install.

1) mods to original kit are required. Fuel pump, MAF, and IAT sensor.

2) the 2.2L supercharger is too small for a 6.8 L motor, and head unit has to spin 2.5 times engine rpm which creates alot of heat even when bypass valve is open.
This means summer IAT at cruise around 135 degrees. Boosted 5 psi IAT around 190 degrees.

3) kit needs a really good intercooler to cool intake charge. However this will do nothing for a 190 degree supercharger that is heat soaked. Spraying water methanol into supercharger is not recommended by KB but alot of people do it. This will cool the intake charge and head unit but to do it right low gph nozzle should come on at about 3 in hg, and high flow nozzle should come on at about 2 psi boost. This will use alot of water meth solution.

4) my opinion is the supercharger kit was designed poorly and should NEVER be used on a heavy vehicle in weather above 75 degrees without a way to cool blower and boosted air. Towing is out of the question unless gallons of water are used to cool system off.

5) I will run the system this winter, but next spring I will sell the complete kit. Twin turbos will be put on next summer. A much better solution in my opinion...Cruise IAT will be much lower, and the ease of intercooling will make boosted air much cooler. Twin small 16G Mitsubishi turbochargers should be perfect. Plus they are water cooled units, and I have a spare one from my Eagle talon build.

So, overall the 2.2 L Kenne Bell TS6800 kit is a flop and due to supercharger changes at Kenne Bell a bigger unit will not bolt up or fit on this system.

My advice for excursion owners is to opt for a set of turbos instead of a small supercharger. Lighter pickups may not have issues but a 7500+ pound excursion does.

Just my thoughts....keep an eye on ebay next spring. My complete kit will be up for sale to pay for a twin turbo setup.

 

Most definitely will be watching for your extended build

 

Twin 88's or go home

Absolute bummer after all that work and effort it ended up being a bust. At least you found that bad main bearing before it left you out to dry though!

 

Have you given any thoughts to a Paxton/Vortech supercharger setup? Do they even make a kit for the Ex?

Seems it would be a lot easier than a twin turbo setup, no?

 

I am a little more comfortable with turbochargers.

They have wastegates to limit boost, and the small 16g seems to be the perfect size for producing low rpm boost and stay in its efficiency curve.

I've never worked with a belt driven centrifugal unit and don't know how they limit boost.

One of the things that is pushing me toward twin turbos is the dual MAF translator. It takes the readings of 2 MAFs and combines those readings into a single 1 to 5 volt reading. Simplifying the intake piping significantly.

 

OMG!!!!

I put a Aquamist water meth system on the supercharger setup!!!! Took a little to tune it right and WOW! 60% water and 40% methanol triggered via injector duty cycle. Adding 16 gph at WOT WM solution.

IAT's are down almost 100 degrees, boost is up to 8 psi and the POWER OMG!!!!

2WD on pavement broke loose both rear Toyo M55 tires with little effort.

My chipped 7.3 diesel pickup couldn't even do that.

I'm keeping this monster!!!!

Have to give thanks to the corral supercharger forums for water methanol advice and it's fantastic.

Cruise IATs are still on the warm side 130 ish in 75 degree weather, but a bypass valve intercooler will help that. WM does not activate during cruise.

It's like driving a 8000 pound sports car. I'm figuring over 500 hp. Limiting factor was injectors as they could only support 450 hp or so but the methanol adds to that.

Another KB kit on ebay. This one lacks the lower intake, alternator pulley, injectors, boost a pump, tune, and instructions. He still wants $3500 for it. The lower intake has to be aluminum or steel. The temps this system puts out could melt the plastic version. You would have to find a 1999 V10 at salvage yard and pull the aluminum lower to use this kit on our excursions. Couple hundred dollars for a machine shop to make a alternator pulley for it. So this kit would cost about $5000 after you got injectors, pulley, fuel pump, tune, and lower intake. $5800 after a water meth system. Plus installation labor.


Twin turbos would be cheaper. Maybe I will twin turbo my other exvursion. Kind funny....I have twin 2000 excursions, one with a twin screw SC, and the other twin turbos....I may have to do that.

 

Well, now we need some videos...

Getting a tune with a shift defuel wouldn't be a bad idea, especially with your power now. It certainly helped prolong my trans for as long as possible before o built a new one.
