Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

M90 Porting...

The coolant from the heat exchanger on the cold side is directed through the front drive casting - not associated to the oil reservoir - then said cool water moves front to rear contained by a made cavity heli-arced into position. Water then exits on the return side of your aftercooler to be re-cooled and recirculated.
Blowers with shorter drives use a second patent pending design that circulates water in a 360 degree arrangement.
Thank you

I like the gains of this design and if your going intercooled tapping into the lines there would be so easy... but is Coolant really a good idea going into the casing??? I mean coolant vs supercharger fluid... really?

Or am I way off base and the snout hollow and your simply tapping into that area? Just curious on the idea, I would think coolant in the snout would be dangerous to the seals and stuff.
 


^ This is correct information. A new cavity is created for coolant only, it cannot leak anywhere the oil is.
 
:th_lightbulb: Really?!? Actually, cooling the case prevents heat soak,adds consistancy to the performance and will improve longevity. It's all been tested, it's not really open to conjecture at this point. :D Now, I'll probably be the first to cool the supercharger without the use of an intercooler so we'll see how that does, I'll be able to run it with and without the system operational. Regardless, if you can reduce case temps (and the supercharger is a heat sink for the entire engine) I see that as a benefit over a 200 deg supercharger any day. BTW as I said before, KB has liquid cooled superchargers and GM is patenting their own design. If this were a warrentless mod I doubt they would put the time and resources into cooling their blowers. I like that Bob can modify our existing pieces to work similar to these high dollar designs.

Lets just say that the blower flows 800cfm at 17psi. Doesnt it make sense to remove some restriction (port work on heads, lim, blower housing...etc) and get the charger to put out 800cfm at 11psi of boost.

I modified your example a little. If you port the heads and LIM, boost will drop. If you keep the same supercharger pulley, CFM will go up. You are making the engine more volumetrically efficient, which in turn makes the blower more volumetrically efficient. More air with less boost = more power.

Given the engine air requirements are not changing in the scenario i'm suggesting and the blower drive ratio is not changing, if there is less pressure in the manifold, the blower is moving less air.

No... CFM will go up if you're drive ratio stays the same but boost goes down due to headwork or other mods. Less boost means there's less pressure going back up against the blower. There's less air pushing back through it and more air coming through the inlet.

You can isolate the SC from the engine using a layer of phenolic. That prevents conductive heat but still allows convection. Nonetheless, the SC will probably drop from "200 deg" by 40%. BTW did you measure or assume the SC temp to be 200?

So, with that in place I would be interested to know your improvement. Seems easier to do than a cooled SC case.

look at my blower temps from the other page.
