I never have to add oil to the s.c. so I am going to leave well enough alone for now.
I am very **** about the oil level in the blower though. I run it just a tad low all the time.
Best oil i have found is Redline shockproof heavy. It runs the quietest/coolest. But the level is critical.
I also flipped my by pass valve around so that the boost air goes into the side port---so many have different recommendations concerning the valve, spring, no spring, mount this way that way etc.
So I just referred to the oem Audi and other euro manufacturers recommendations. It may be just my imagination but it seems I have a tad bit more vacuum showing on my boost gauge at idle. It didnt affect boost at all. IDK.

I allways ran mine level to a little bit over and usually had a nice thin film of oil coating my engine bay.
Love that smell

I am down on power for the same boost level, compared to the 10 to 1 rotors, but I have a very small SC pulley to make up for it.
I suppose it can take more boost?

We have 2 new Kenny Bell superchargers on the way. When i was at pettit i always woundered what a bigger SC would do and were finally going to see. Norm ordered 2, thanks to contributing to our delinquency. A 2.1 is going in his car and im going with a 2.6. Oooooo, yeah

Ok the cat is out of the bag.
Here is is guys---
this is NOT just a bigger blower--its a totally new designed blower and system. Go to Kenne Bells site and read. A LOT has changed
http://www.kennebell.net/KBWebsite/H...s/Homepage.htm
Many many benefits from this----lower parasitic losses, lower charge temps, higher power,
quieter, etc etc etc.
Very exciting.
Moon you have a PM.

My question is how much (more) can we flow, and at what boost?
If only it was simple division, like 1.3 into 2.1.(or 2.6)
Also, 18,000 rpm is a step up on top blower speed.
Not that we would ever, ever want to overdrive, after all 640K is enough RAM for anyone. LOL
I am guessing 15 to 18 PSI instant boost, but its really a toss up as to what the new blower will do.
The low compression rotors should give me some leeway, but this will still be a lot of boost.
PS: April 1st is not a good day to announce anything....

moon - when yall get a solid-ish price on the 2.6 let me know
I've already done a good bit of research on them
I don't mind being a guinea pig
but how will temps be effected?
I would expect someone should out with a more efficient water pump to handle them

one of the main things a larger blower will bring ( and by the way the 2.6 is only about 1.5 inches longer than ours) is the same flow we have now but at a much lower blower rpm.
Now get away from "Boost" and start thinking flow. Now our blower has to spin at a pretty high rpm to provide the flow we now have. I haven't did the math but the new blower should not have to spin nearly as fast. That means less power used to drive it for one. It also means that the air will not have to be compressed as much to provide the same flow--so that means less heat
In detail read this page: http://www.google.com/url?sa=t&rct=j...Sk4jlfz-Jdrziw
This opens an entire new chapter in the book! The 2.6 has the potential to move enough air for INSANE POWER. We dont what to do that though.
Levi, engine cooling will not be a problem--i have something up my sleeve too.

I would recommend setting the pulley ratios to push "only" @5 to 7 pounds of boost initiallly.
You may find that is all you "need" for great power and even better longevity than the 8+ everyone is using now.

The key to kenne bells success over the years has been the intake manifold and the overall simplicity of their kits.
This does not get discussed as much as the specs of the blowers, but is much more important for tuning and reliability.

The blower is nice, but you could slap pretty much anyones (lysholm, sprintex, etc) twin-screw into that kit and get similar flow.

This page is also worth looking at: (i do like their large intake)

Actually, the blowers are different, they move much more air for their outside dimensions.

My only point is that the intake manifold and kit design are more important for tuning and reliability.
Of course, since we are only going to end up with one new manifold there will be no way to know if it is a good design.
If the new blower makes more power, with less boost and heat, then lasts for several thousand miles i'll be impressed.

I didn't mean to insinuate that they are not high quality. The technology has improved a lot in the last few years.

Its also the inlet side of the SC thats important and changed. DOnt forget that too. I think Moon has in mind a system that will allow the use of the stock airbox?
Dont forget the watercooled option either ( if needed), the redesigned rotors etc etc. Its definity a move up. It will be less strain on the engine, you will not need as much belt tension either. Remember since the sc vol is larger it doesnt need to spin as fast. That means you can use a bigger pully on the blower which means you can get more belt wrap. More belt wrap means you can reduced the belt tension---another win-win.
I wish we could do without the ssv in the intake. I hate that valve.
Damn that is an expensive water cooler pump! 55 gal pump! Holy Batman--we DONT need that flow rate. Mezerine makes a smaller one with a flow rate of about 20 for a lot less money IF it is found that it is needed. Many more options than that hunk of gold.

Mezerine also makes a flow rate of 42, in a larger HD pump, for about the same price as the 20.
Still, if I had either of those pumps, I would seriously consider using it for engine coolant.

I do wonder has anyone tried to tune with the ssv locked open? I think in the days of the interceptor the ssv opened very early?
I am continuing to collect data concerning coolant temperatures etc and I plan on installing an EWP this summer. I do believe a lot of cars are having extreme coolant temps after shutdown. I have already measured spikes of up to 35F over the shut down temp. Its cooking in there.

rev it up
the hymee kit comes with a 2.1 L unit. The current pulley seems to see close to 10psi however the boost is very temporary as it looses boost as quickly as it develops.
Perhaps it requires a smaller pulley with higher psi for more sustained boost.
