At this point I think we are going to need that area for the MAF. Then we might have to use behind the grill for the aircleaner. But I don't know yet. We will be including a new MAF housing similar to but not the same the RB unit. (Since I make that one for them anyway)
It's just a matter of finding room for stuff. Also the tuned legnth of the whole system must be worked out. In unboosted operation we must keep it so as to run like stock.
Bottom line is keep your RB kit intact so you can sell it. You will not have any trouble finding buyers.

Nope, we just do some production machining for them. They send us plans for bid.
They send us the raw castings. We build the tooling, make the programs, machine 'em and ship them back.
We are ******, want something made? Just send a plan and money.

Richard why can't you do a self contained oil system such as with the Eaton blowers or the Paxton units? Why couldn't you just use a nice industrial jet turbine oil (which would be appropriate btw!!!). I wouldn't think you'd need a whole lot. Even a 757's engines have a self contained oil system in each engine and they only run a total of 11 quarts per huge engine!!! If you could do this, it would really ease installation not to mention the fact that we wouldn't have that crappy hot engine oil running through it. I know it shouldn't really affect the air temps due to where the oil is flowing but it still doesn't sound like fun having to tap into an oil source and run a return line.

The fact that it is small is the problem. There isn't anyway to get an oil pump in it. I looked at trying to get a spinning bearing to pump oil. The shaft is moving so fast that putting an eccentric on it is out of the question. An external electric pump adds componants.
Be sure I don't want to run hoses and have to tap the pan. The tap will be easy because we are going to supply an oil filter sandwich. For the pan I'm not happy with tapping the stock one and may cast a new one. That much more money but it will be an option. It can't hurt to add a little oil to the sump and even some added cooling by putting some fins in the airstream. May as well as long as I'm casting it. Might even have some sales to NA guys who run on the track and can use better oil control. More oil and trap doors to keep it at the pick up. We do that all the time with piston engines. In fact I haven't built an engine without a custom pan in 25 years or more.
I'll be listning to any options anyone might have on this.
BTW we've got our own "storm" here in Chatsworth ours in the form of FIRE.
Sat and watched it yesterday going right through the hills not more then three miles from here. Today it's heading for the canyon where I have all my stuff stored in a semi trailer sitting at a horse ranch.
Which is also the exact area where we had our little drive two weeks ago. With another set for Sunday I don't know if it will come off.

Our engine already has an auxillary oil pump to meter oil from the oil pan into the engine. Could you use the following adaptor to run 2-cycle oil from a reservoir through the blower then into the engine?

Hi,
yes I have, and it is in stock. The price is $ 94.00, including shipping in the US.

I know you've been over boost levels and whatnot, I think you said something like 7 or 8 psi is what you are shooting for. Will you be tuning for higher boost applications? I know you'd like to keep things locked because you don't want people messing with things and blaming you, but will your supercharger compete with some of the recent FI applications?(PTP made 346 horsepower/ 13.2 PSI IIRC) Now on 8 PSI I don't think that is possible, but what do I know? Thanks Richard

Lets say I gave you that much boost, are you going to complain about needing $10.00 a gallon gasoline? Will I get a ration of **** from you when you need an overhaul at 30,000 mi? Or less.
There is no free lunch. Not here or over there.
Let's just get this out my way and then if you don't like it we can give you more. I'll wait until we see how much the trade off is.
IMO a 7-8 psi will be reasonable for a great street car. The proff is in the driving experiance. Not just boost gauge or dyno read outs.

Just remember with axial flow I can have all the pressure I want. Unlike other compressors these are staged and adding stages compounds the Pr.
In this case by about 1.11-1.12. So, how much pressure do you want?
Modern gas turbines run around 200psi plus. The B-1 bomber has almost 300!!
When you need more volume you just make the blades longer.
This of course is oversimplification. Not that ez.

You need a "build your own" type of kit. Choose the parts you want from tha available selection around and put it together like a puzzle. I know that's an over simplication and also not easy for someone to assemble either but you get the idea.

That's a joke, right?
Or are you in the habit of going up in a lot of planes where the pilot built the engine in his garage at home?
Yes, there will be some range in the speed for further airflow.

It then becomes a true turbine. Not an efficient one though. You can put the energy into the air and have the work come out as shaft power. This way you get the air moving off the blades and taking the energy with it. To truly use this type of energy correctly requires a different blade design. Using the geometry of either for the other results in loss of efficiency.
So if the engine were to backfire the compressor will reverse direction. The energy put into it will be used to make the belt slip. It's that simple.

Weird. I drove my 400hp Eclipse through Florida rain and I never felt this desire. :p
I found it helps to not push the throttle all the way down.
