But im talking about the factory intercooler m112 setup. It needs all the efficiency help it can get.

 

Seriously, you're talking about spending money. How much evidence is there that what you're saying is the right way to spend it? I'm not aware of any for our cars.

 

That is why I went with an oil separator, and now have the meth kit. There were deposits of oil on my TB and intake elbow, so I can only imagine what the aftercoolers look like. I did experiment with water/meth misting on the on heat exchanger too.

 

Spending money? Hot tanking the aftercoolers is cheap once they are off. And like Michael said an oil catch setup is the way to go to prevent future buildup.

 

I wish I would have done mine when I had the s/c off. I figure now though the combo of the water/meth and nitrous/gas that will go through them will clean some of it off.

 

It should help to clean them but the few people who have did not report anything noticeable in performance.

I think it a small effect.

Exactly. I had a full work bench and I told everybody, stay the f*** away from this work bench! I place everything in order and in red bins. Took my time since it was my first time doing it. Read all the Jaguar tech info instructions the night before, looked for pics in the forums and advice of anybody that did it before, etc. Patience is key!

 

Great timing for this post. I just started taking off all the peripherals around the bad engine in the 03 STR I recently purchased. I decided to pull the supercharger this evening and got stuck trying to access the back 3 bolts.
First thing I did when I got home was search the forum for how to remove the supercharger.

Getting the EGR out had me stumped. Now I know, thanks to this thread!!!

 

There are some very helpful people on here and the pictures, step-by-steps etc are a tribute to them.

 

I finally removed the supercharger from the engine! What a PITA! It took me about 4-1/2 hours total. Removing the supercharger air intake manifold was very difficult.
First removing the EGR valve assembly was not fun, then accessing the lower 2 bolts holding the intake manifold to the back of the supercharger was even more fun.
Finally the 2 bolts holding the intake manifold bracket to the top of the block were very hard to remove. Specifically the one opposite the EGR. 40 minutes on this one bolt, 1/16th of a turn a time.

Instructions are great, but getting it apart can't be written in words....

 

One of these will greatly ease the pain in removing the rear horizontal bolts that thread into the bosses at the back of the elbow. Gearwrench part number 9551 - 10mm stubby flex ratcheting wrench. I had them out in a few minutes after removing the EGR valve. Amazon has it:

 

I started this job a few weeks ago because the coolant hose under the supercharger failed. I got it most of the way back together and discovered I have to take the supercharger off again. Just in case anyone can be a dumb as me sometimes, this was my mistake:



Note the hose that connects the left and right fuel rails. I swiveled it up out of the way when I removed the supercharger mount that is still in place in this photo. A month later while putting it back together I neglected to swivel the hose back under the supercharger, so it now runs over the supercharger snout. It would probably be okay there, but I'm going to pull it apart tonight and do it right.

 

As for the intercoolers, I soaked mine in the parts washer for a week, then used a couple of cans of throttle body cleaner on each one and was still getting gunk out of them. Water flushes through them much easier now. How much that will improve the performance is unknown, but it couldn't hurt.

 

Anyone know if it's possible to swap 3.0 Litre naturally asperated intake manifold with supercharged intake manifold intercoolers and replace supercharger with fabricated box to connect with normal throttle box and intake plumbing. Great way to get around having to remove intake manifold to replace plugs and coil packs on off side engine bank.

 

If you have to ask, don't even start!!

 

What would you gain by doing this?
Seems expensive because you should not need to take the manifold off very often??

+1 on not attempting such a modification.

There is a specific reason for the shape and length of the inlet manifold fitted to the 3.0 litre unit to allow air entering the engine to change speed depending on load.

Such modification will also prove problematic when going for MOT or smog check.

 

I am in the process of changing a bad injector. To change the injector the intercooler needs to come off, and to get to that the supercharger.

So far I have it apart to the point where the EGR valve is next followed by the supercharger, which I will start in the morning.

Once the Supercharger is off, are there any recommendations for maintenance while its off? Minus cleaning everything of course.

I was reading awhile back about changing the supercharger oil, from what I gathered it would MUCH easier to do while it is off.

 

defiantly change the valley coolant pipe and SC oil when your in there . a lot of people change the two knock sensors as well but i don't think thats a must ! check the sc impeller coatings and bearing function as well , also change the brake booster vac pipe o-ring and the evap and PCV pipe o-rings too , now is the time !!

 

Also, if you have any reason to suspect the air conditioning refrigerant may be leaking, recover the refrigerant in the system and change the o-rings on the connector with the expansion valve. The fitting is inaccessible when the supercharger is in situ.
