New M90 SC kit on it's way.....

[NVA-AV6]

Revision 2 (Final Release) kit finally finished and in testing......




Small video, still tuning it out so only a 80% throttle pull at 7-8PSI....

Looks awesome Paul. I may have to snag that and everything else from you. Time to start saving.

Nice.  I must get a ride the next time I'm down there.  The last time I was there, the motor was out of your car, and the time before that the SC was out because you were rebuilding it.  We will talk soon Paul.  I'm glad to see you had time to get things up and running.

Sounds awesome!!!!

Looks sick. Nice job Paul.

Time for a update, made a little change this time and Water jacketed the actual blower to remove heat at the source. This should not only reduce added heat to the charge air but also extend blower life and performance by keeping it cooler.Well, here are some pics of the Water Jacketed M90 on the moch up stand I have. Still waiting on a few odds and ends to install it on my car for testing.

To be blunt... Fucking amazing!

Great idea Paul.  What's your opinion on the water jacketed snouts that Stiegmeier makes?  Is that something you've considering doing to improve bearing life?

[NVA-AV6]

I did think about it and could easily do it but the compression housing is where most of the heat is generated.

Someday I hope my engine can be that badass...

I did think about it and could easily do it but the compression housing is where most of the heat is generated.

I read up on the research that Stiegmeier did and from my understanding, they found that there was a significant difference in temperatures at the inlet end of the case and the snout end of the case.

When will you be doing testing on this new set up?

Well the first one is in and started testing. now I need to start building a tune for my car with it. There is one design change I still have to make, I originally wanted to use "short" adaptors for the mani and SC to allow for customer customazation weather they wanted to use different means of aftercooling or not, and use a silicone 90D elbow at the mani, but the vacume of the engine causes it to collapse partially, I can get by with it to start testing, but already ordered a bunch of 90D cast aluminum elbows and will have to re-make the mani adaptors. The only positive is I will also be fabricating in a 1/8NPT bung for water/meth to shoot it into the center of the mani opening.



Also Bob your core failed, after the SC reached full op temp I did the first push to about 4psi and one of the teeth on the rotor gears sheared off and allowed the rotors to declock and impact each other. I had a couple of extra rotor packs left over from housing porting experimants and so I replaced yours with one of them after cleaning up the inside of your housing, the impacting rotors lets some aluminum lose and lightly scratched up the inside of the housing in a couple places.

And here is a pic of the PS pump inlet elbows. I really need to clean the lense on my camera.



Oh and while doing this testing I have some additional fun, I get to rebuild one of our 5sp ATs, I finally found a source for upgraded clutches and am going to give them a try and see how they hold up.

Any updates on this project?
