Might just be dirty. Try cleaning it in place. Replacement takes less than a hour once you figure out what has to be removed to get to it. Make sure you have the correct belt size.

 

thanks guys for your response.
I really just got the supercharger installed recently about 3k ago. the squeaking comes and goes. I'm gonna try to clean it. don't know if it's just getting loose. is there any danger in spraying water direcly on the belt?

 

btw dog, did you get your car all fixed up and what was the cause?

 

haven't got it back yet, but that's a non supercharger related issue.

anyway, my installer said the intercooler line needed to be burped, which he did. he says it's making boost again.

hope to get it back tomorrow or friday.

 

Sraying it with water will do no harm. I would spray it and the pullies with ORANGE cleaner to remove any oils that might be on them.

 

you're a wealth of knowledge thanks. I'll try it this weekend.

 

got it back. still not fixed. not sure what's going on here.

i am registering positive boost (around 5 psi at close to redline). however, the car doesn't seem to be making any extra power. you don't get the supercharger surge as the revs increase.

engine coolant temps seem to be normal.

EGT's are really high still. only got as high as around 950-1000 on the dyno. i'm seeing 1450 at full throttle around town now.

car is running very rich. it is dipping well into the 10's at WOT. if i remember right, i was running around 11ish on the dyno.

i have noticed that the intercooler is warm when the car is running. never checked it before this. is it supposed to be very cool?

anybody got any ideas? the only thing that is different from when the car was running really strong are the addition of silicone hoses and the relocation of the intercooler water pump.

 

Look at it this way, since your car has been gone (last 3 mo) you have had room in your garage for other additions.

 

Dog:

IF you are truly getting 5 psi boost from AFTER the throttle body, then it is not your blower or plumping. I would take a close look at the following with your scanner:

ALL ON A FULLY WARMED ENGINE

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.

It's going to turn out to be something obvious. Didn't you have the hoses reinstalled? This would make me think it might very well be that your intake temps might be too high as a result of improper install of the lines. Open the cap on the fill tank and watch it circulate. Top connection on the aftercooler should be connected to SIDE connection on filler housing. Water should be coming into the filler body from the side and returning to the radiator from the bottom.

Coolant should always be cool enough where you can put you finger in it without getting burned.

what did your techs do to "fix" the your problems?

is your car still not pulling as hard as it used to?

maybe your high EGT is a faulty reading. running rich and high EGT doesn't make sense. with a rich AFR you should be running cooler. running rich tells me that there is a boost leak or a faulty MAF.

double check your AFR and EGT with a third party and you might as well do another dyno. maybe you are just getting used to the power... i know i've gotten used to it

the intercooler should be warm on the outside but the water should be cool enough to touch.

did you ask todd at EVO? what do they have to say?

 

I agree with Karlooz on this one except that your friend louis found it lacking power and he's not used to it, take it back in! At the moment "If" the engine seems REAL HOT like in your orginal complaint then believe the 1450 F temp is correct (that means your close to melting something at full load) so take it back real slooooow. You have the AFR on one exhaust side and the EGT on the other side right? so you don't no which is correct unless it just seems real HOT. PS make sure you have water in the resevoir for the IC. It just seems strange that this all started with some plumbing changes.

 

My intercooler was stopped up with pipe dope material and I had to soak it overnite in radiator cleaner and then reverse flush it with water at high pressure. The differance was nite and day. The car runs great but I still get CEL after a few hundred miles. Todd thinks it is from high altitude. Also try adding coolant after warm up in case there is an air bubble with the rear end jacked up high. This is what Todd tried in AZ when my flow was low, but it didnt work due to the stoppage that I found later. Will

 

I just drove Andrew's car again. I have driven this car in every step of its set up from stock to now. It is definately not running as stong as when it was 1st installed. The car used to scream and throw you back in your seat. Andrew gave my father a ride and his "seat of the pants dyno" felt the car was faster than his 02 GT2 (the jury is still out on that one). It feels like a 996 with minor mods.

 

Talked to Evo. I told them the my guages were pulling crazy numbers and that the car did not feel like it was making power. They said they would talk to my installer and call me back.

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.

 

dog,
hang in there. we are all learning a lot from your experience. I'm not sure why your installer can't find what is wrong. you almost need to re-install the entire blower (or bits and parts of it) to find out what is happening.
