Turned the key and put the new engine and AED blower through its initial maiden voyage about an hour ago. Primed the engine and fuel pump and she started first turn.....stumbled and hunted for a few seconds and idled smooth as silk. Lots of oil pressure with that FRPP pump. :D

The blower does make a little noise though. Are they normally a little noisy? It almost sounds like a bad bearing in the alternator, I did the old long screwdriver to the ear test, but when I put the screw driver up against both the alternator case and then the blower snout, it seemed to be the blower the noise is emanating from. I know this is a stupid question, but AED does send these things full of oil don't they? I notice the paint mark on the service plug, which tells me it was initially filled? It’s never leaked the whole 2-years I've had it sitting in the box in the garage. I haven't popped open the plug, service plug since it's such a PITA, but I thought I should ask you guys what you thought before I let it run anymore.

Umm...I don't know about AED, but from my experience, most manufacturers don't ship their parts filled with oil. I'd definitely check that.

Maybe a video is in order? I'm no expert but I'm sure a video will help identify a normal blower sound to a faulty one. You still have your Photobucket account? Just save it on there and post the URL address on a reply here.....plus I want to here that beast!!:D

Yes it has oil from the factory...

Mod Motor Cat,

Congrats on the start-up. That always feels great when it all comes together.

As for the noise, check to make sure the blower pulley is torqued correctly and that the nut is not loose.

Then if you still hear a gear like whine from the blower at ilde, press firmly down on the center of the plenum cover and listen again. Did the noise get worse or the same?

It is possible that you have a bad bearing in the Eaton M90, but I doubt it. If you did some porting you may have gotten some spunker in the housing but the bearings should be protected.

You can check the supercharger oil level, but they come filled from AED. Unless somebody drained it out and forgot to tell you.

Keep us posted,

A-Train

Glad you got it going. I'm sure it felt good to get your torque fix again.

I lost the bearing in my snoot on my M90, as did another guy that bought his about the same time. The cost of Magnuson to rebuild the blower is 50-75% of the cost of a new unit. But they don't make the Rev III anymore...

Make sure your pulley nut is torqued down properly, if not you'll be paying for a new shaft, bearing and pulley.

Well.....looks like Tony hit the nail on the head. I pressed my hand down firmly on the center of the plenum and the noise goes away. Take my hand off and its back. I initially thought it might have not been sealing properly between the manifold, plenum spacer and the lid, but I’m not feeling any air escaping anywhere, I’ve got plenty of sealant on both sides of the spacer, the bolts are torqued down nice and tight and since it idles right down and doesn’t surge, it doesn’t seem to me like there’s any sort of vacuum leak. I guess it's just the noise of the airflow rushing up against the plenum lid? It’s probably just amplified by the spacer? Is this a common occurrence after adding the spacer, or is there something that can be done to correct the problem?

I decided to double check the oil levels, just for piece of mind and they seem to be fine….and the oil is super clean, so if anything was grinding away in there for the half an hour I had the car running yesterday, It should have left some sort of residue, or grindings…..which there wasn’t.

As far as torqueing the supercharger pulley, I'm assuming making sure the nut is on as tight as possible using hand tools is all that's required? I didn't like the idea of putting the impact on it, so I just held it with a pair of channel locks and cranked her down with a long handle 18mm wrench.

I welded in my exhaust turn downs and the bung for the wide band O2 sensor tonight, so I might take a look at tackling that tomorrow. We'll see how motivated I feel. :D

Josh, I brought out the video camera with me tonight to snap a quick clip of the running car, but got so involved in tying up some of the odds and ends I didn’t get around to it. I’ll see what I can provide you guys with tomorrow.

50 ft-lbs of torque...

Mod Motor Cat,

The nut should be torqued to 50 ft.-lbs. It is difficult with the blower on the car since you really can't hold the rotor from spinning when you try and turn the nut.

I used a good quality rubber strap wrench to hold mine and then torqued it to 40 ft.-lbs. of so. At that point it was a loosing battle.

If you just hand tightened it there is a possibility it could come loose in the future.

If the plenum cover was braced better it wouldn't resonate so much. Once the boost starts flowing the problem should go away since the upward rush of air will flex the cover and stop it from resonating.

Yeah, I guess we lost that luxury of quiet opperation when we went with the 1" spacer. I'm thinking that small divet in the center of the plenum lid was meant to rest on the top of the intercooler brick to keep this from happening. Ah well, maybe when the hoods closed and underhood temps warm things up and stretch things out a little, the noise will go away. I'm certainly able to live with it over the sound of a bad bearing though. If anyone asks, I'll just tell them it's meant to make a little noise at idle......kinda like a centrifugal. :D

Awesome!!! Congratulations. Enjoy that beast. Get her on the road yet? And how did the belt turn out with the original idlers?

Thanks....

No, she's not road worthy yet. I've still got the steering column apart trying to hook up some of the wires for the Wide Band and I'm still finishing up my trunk mounted battery bracket.....but otherwise, she seems ready to go.

The original idlers work just fine. I had to shim one of the idlers slightly with a washer, to center it on the belt, but otherwise they run strait and true and the belt doesn't wander or slip (at least goosing it in neutral). I'm quite happy with the way they turned out.

The biggest thing this car needs is a bath, inside and out. It's got 2-years worth of dust build up all over it. I'm not even sure if it's Alpine Green under there anymore. ;)

The Video is coming guys....I just want to button everything up first. :D

Steering column? Why do you need that? ;)

Can't wait for the vid!!!

You guys have probably lost interest by now, but I finally got a few under hood shots to post. No video yet, but hope these will tide you over for now. :)

Under hood.....




Custom intake pipe I made. Starts at 4" at the Lightning MAF and transitions down to 3" into a 75mm BBK T/B.




My attempt at showing you my Supercoupe boost gauge and tach face....but I suck at digital photography. :( And yes my American friends.....that is km/h.




The only place I was able to find to mount my Kenne Bell Boost-a-spark.




.....and finally, this is what happens when you've got too much time on your hands and try to get fancy with your custom battery hold down tray. God I love the Plasma cutter! :D



More shots (and a video) to come when it's finally warm enough here for me to wash this damn thing. :(

Cool pics!!!

Thanks for the update.

What are those two sensors on the side of your plenum spacer?

Those are the Hobb pressure switches for my Kenne Bell Boost-a-pump and Boost-a-spark units. They're designed to come on at approx 3.5psi and increase fuel and spark delivery as needed. I figured it was easier and cleaner mount them into my spacer than it was trying to drill and tap the manifold while it was still on the car. :)

That is one sick Cougar! ModCat you sure did a great job :thumbsup:

Now for some questions:

what is that black box by the drivers strut tower

did you cut into the hood for the spacer? If so pictures?

The black Box is my secret weapon. When activated, under WOT it sends a signal to the ECU instructing the cars A/C unit to act as a secondary cooler to chill my air charge, resulting in another "emergency" 50-60hp when I need it. It also has a feature to interrupt the ignition signal of any other vehicle within a 25ft radius. Great for those stoplight grudge matches where you wanna make sure the other guy isn't firing on all eight, so to speak. ;)


......just kidding, it's my car alarm. :D

Yeah, I chopped some of the bracing out the center of my hood to clear the manifold after the spacer install. It actually didn’t work out too bad. I cut the same section out of the sound deadening material, then glued it to the underside of the hood, so it didn’t look like such a hack job. I'd still rather have a cowl hood, but this will do for now. :)

I’m back home now and my car is at my parents place, so you’ll have to wait for tomorrow for more pics.

How much does your intercooler reservoir hold? Looks like it fits perfectly in the abttery tray spot. Looks nice! And also, how did you make the intake tube? It looks perfect.
