Did you watch the colland flow when the pump is running? Is it running smoothly? What are the reading of the sensors I described above? If in fact you are getting the boost you claim (5 psi) ANY the intake air is a moderate temperature, your stock sensors will point you in the direction of the problem. Nothing to fret about, just take the readings.

again, what exactly did your techs do to your car? it would help us diagnose it and it would help if bert smith moto chimed in on this thread.
don't trust your aftermarket gauges, they may be improperly calibrated.
still sounds like there is some blockage in your IC hoses. like Jim said, check if there is flow. turn the ignition key on (but don't start the car) so the water pump is running. you can then check the filler reservoir if the coolant is circulating.
maybe get it re-flashed? it couldn't hurt.
i don't think it's the mod that's causing you trouble. it sounds like the install.

I did not hear back from them so I called my installer. He did in fact speak with Evo this afternoon. My installer said Evo wasn't really prepared to go any futher to diagnose it without another dyno run. I asked my installer what he thought about the EGT's and AF readings. He is blaming that on faulty sensor readings. I did run some boost tonight and checked the IC coolant temp levels. It was hot, but I could keep my finger in there. Boy, what a leap of faith that was the first time I dunked my index finger in there
There is certainly plenty of coolant in there now as it bubbles out when I take the cap off. It's chock full.
Not sure what to do now. This is getting old. My car has spent more time in the shop than out since this little project. I hope to get this resolved soon. It just seems like it's one thing or another with this mod.

Just to review some of the obvious, consider again the Filter, which may have been too oily and is starting to affect the MAF. I was told by Todd to wash the filter in warm soapy water and let it air dry. My first filter was not treated this way and my MAF went out early after the install. At first it just manifest by lower percieved power and eventually started cutting out the engine completely. It may just require cleaning the element of the MAF with electrical cleaner spray or a new one. I keep one on hand at all times now. Just a thought, Will.

Dog, hope you get it figured out, almost sounds like more trouble than it's worth (the sc mod). Has anybody out there ever had a truely uneventful install, or do we just hear about the bad ones?
I've thought about this mod a dozen times, think I'll just get a turbo.
Just playing the Devil's advocate.

i think it is all in the install. mine has been PERFECT. no CEL, MAF issues. one thing that did happen was a blown off boost hose (happens to the TT guys too) at the track. easy fix, i just tightend down the hose clamps.
7000 miles with the SC and 6 track days.

Increased air needs increased gas. It's about as simple as it gets. Either the aftercooler is working or it is not; the blower is working or it is not; the tubes either leak or they do not, your stock sensors either work or they do not, your plugs are either good or they are not, your belt is good or it is not.......
Doesn't get much simpler than that IMO. Until DOG gives us the reading of the sensors I mentioned above, there is really no further help I can provide him with.

1999: Do me a favor. Please list the readings that I should provide and spell them out. The ones you posted before I couldn't figure out the initials I'll try and get them tonight. Thanks.
WYO: I got brand new plugs and a brand new MAF when we did the install.

Dog I agree with 1999 on the parameters
1) STFT at idle and while cruising around 25oo rpm.
2) Engine load at idle
3) What is your LTFT?
4) Timing and rpm at idle and a graph of timing at WOT to redline
5) MAF at idle and at WOT near redline
6) Verify that the water is circulating through the aftercooler and it is going in the right direction.
he and me included wish to see, it pays tribute to a great ongoing thread, however knowing what to fix and fixing it yourself are 2 different stories. Many times I take my car in to have it diagnosed and I make the repairs myself this saves on my overhead cost of expensive tools and there book repair time. Here is a link explaining some rational on his thinking this is for standard engine.

Here is what you need to check: (This assumes that you have a true 5 psi at redline and that your coolant for your aftercooler is circulating properly)
With your scanner, look at and record the following:
- MAF readings at idle and at WOT above 5000 rpm
- Calulated load at idle and at 2000 rpm
- Idle timing range
- Engine temp at idle
- Intake temp at idle
- Long Term Fuel Trim readings (Both banks)
- Short term Fuel Trim reading range at idle
- Secondary O2 Sensor readings at WOT (Both banks) near readline 2nd gear
- Check that your throttle position sensor reading is getting to 100%
It would also be beneficial to capture a graph of the engine timing and rpm's fromn stop to redline. This will show us if the timing is being dialed back improperly.

My Transmission went out last week at 32k miles. 
I am not sure if it is related to the supercharger or not, but I don't feel like I abused the transmission. I have been told that the transmission in the 996's have been a source of failures for some. The two dealers in San Diego have been hard to deal with regarding the supercharger. Hopefully the parts will be here this Thursday or Friday. It is hard not having my baby around....

The moral of the story, it's all in the install.
When I first looked into this mod, the local evo installer had done a grand total of one, and not without problems, they've since done a few more without issue, but less than ten I think.

ain't that right. sharkwerks did my install and i think they've done 10 before hand and something like in the 20's now.

the car seems to making a little more power now, but it's kind of sporadic. very strange. still not feeling the SC surge of power from 4K up that it used to have. it is making slightly less boost. i ran it to redline several times in a row and only made it to 4.5. i used to hit well over 5 and sometimes it would briefly spike up to 5.6ish.
anyway, the SC is still a little noisy, so I decided to take a long hard look at the whole kit this afternoon. i noticed oil pooling around my SC oil feed line. not good. the car was running and it was dripping down the SC. that explains my recent oil consumption and possibly why the SC has been a little noisier. hope the SC hasn't been affected by the oil leak.
this just gets better and better
