Tama patience is a virtue. Perhaps you are being tested. At least you have yours in that nice garage. I have to wait till the end of the week to go pick up mine! Then I have to hope my road will allow me to get it up and into the garage. And up is not steep. Summer tires just don't work that well in snow and ice.

Sigh,... still snowing too. Patience is a virtue. Patience is a virtue. Patience is a virtue.

Bob, although I have looked for this info I am finding it. So here goes. I remember reading about how one has to, I will use the words, break in the sc. When I pick it up for about for about a 120 trip,

what should I be doing and not doing. Is there also something that Max should be doing to set and or test it when he installs it?

Read the last few pages of the instructions for Stage 1, it basically says 65 miles under 4K RPM and at less than half throttle. Then check the belt tension at 65 miles, 500 miles, then every 5000 miles after that.

... and it's still snowing.

So even with that done, should I do the Autocross the day after I pick it up? Sorry about the snow.

I'll defer to Bob on how to run in the unit. I personally am not aware of any limitations on the supercharger after the 65-mile run-in period, other than the up-front stipulation that it's not for "track" use.

lol - no restrictions after the 65 mile break in. you're good to go. just realize that the belt will do about 90% of its stretching in the first 500 miles. on the track this may be accelerated, as the heat is more of an issue. all it means is that you may need to tension the belt.



in a perfect world, you would get 500 miles on it, and re-tension the belt, before doing a track day.

Rap,



When are you going to be in Bordentown? Precision Motorsports, I presume?



That's 30min from me. Let me know and maybe we can meet.

Got out for a few hundred miles yesterday and some romp-n-stomp. *Great* fun with the extra pickup - even got a "Wow" out of the wife! That's a big deal.



On returning, I noticed the top of the supercharger oil canister was "wet" as if there's a seep around the banjo bolt or the cap. Not enough oil to make a droplet or run down the sides, just damp on the top, so I wiped it off and checked the level which was at "Min". It might have been a tad higher than that initially, and I had about 1.75" of oil left in the bottle (as opposed to the "about 1 inch" in the instructions), so I put the .75" of oil into the canister and carefully checked that the oil level is now two notches above "Min", and I'll take the car out again today and see what's up with that. I re-torqued the banjo bolt, and there are no other indications of leaks or seepage at any points on the cooler, hoses, supercharger, or canister.



The supercharger doesn't consume any oil, but as this is the first major check-up, I'll allow the possibility it's fully bled now and keep a very close eye on it.



I also noticed that several times when coming off the throttle, the car seemed to "bog" as if the engine were braking a little harder than usual, and once when pulling up to a stop sign it even stalled. It never stumbled when on throttle, and the idle was steady, although once in a while it was at 800, and the rest of the time it was just about 900.



I'll double-check all my vacuum lines, and at some point I'm pretty sure I'll need to clean out the ICV because that's what it feels like. I remember when my ICV went with the 944S the car would nose down when coming off throttle.



Otherwise, all is good!



Edit: Oh, I also realized why this supercharger oil smells familiar - it's the same smell as the cutting lubes we used at GE making steam turbines. Interesting that the clearances there were often tenths of thousandths of inches as well.

It's normal to get some seepage out of the cap, the breather is there, if it's overfilled a little it will seep out a little when it's warm.



Check for any kinks in the hose for the ICV and any leaks at the connections.

Yep - I've got the very light weepage on the top as well. No discernible drop in the amount in the reservoir.

yup - cannot have any kinks in the ICV hose. it needs all that air.



initial weeping at the cap is "normal", but once you get the level right (checked fully warm and idling) it will stop doing that.

They all want to kink. It's really annoying!
