Further inspection......this guy isn't using a mill. He'* using a shopsmith or mill/drill. He has no straight-line XY control whatsoever on the tool. His depth control is held by a simple friction clamp.

And that phenolic spacer isn't phenolic. It'* standard off-the-shelf ABS plastic, or I'm a monkey'* uncle. This guy is ripping people off, but in his defense, I don't think he even knows it.

Oh, well, push come to shove, I will run it like this for the trip to the track, I'll take it off and send it in to Intense or ZZP and have them do it right.
I'm talking to my brother right now as I just remembered they have a CNC Router where he works and they do a lot of metal works for hospital equipment. I'm not sure how big it is, but if it'* big enough I'll talk to the operator and see if he has any idea of how to work on this. If he does their Fridays are always open so if I can find a file online for the M90 he can use tomorrow or next Friday might make a good cleanup day for the casing.

Looks like they were trying to copy Intenses stage I porting:

Quote:
Our entry level ported blower housing (INT-PSC-671) features a ported outlet area. This removes all the rough casting points, which eliminates heat spots, and produces a cooler charge.



It looks like there is a bar at the tip of the main opening in the Intense SC, but on mine it'* not there. Is there supposed to be one there? I forget if the one I pulled of my 99 and gave to Travis had a bar there.
If there is supposed to be a bar there I'm guessing there'* a gap in that area over the LIM where a major restriction would be taking place. Enough to have caused the motor to blow up??????

As for the nose drive I don't know if it was rebuilt. I don't know why they would have if there was only 30-45k on it when they ported the SC.

Ok.. let'* analyze what Boost sees.

The two lower bolt areas have been cut out. This is not totally uncommon, make sure you put the two small bolts back into those two holes or you'll have threads sticking in the air stream.

There is a piece that seals off the back edge of the outlet chamber from the holes to remove the rear needle bearings. This was cut out as well. ... why .. doesn't make any sense because the intake manifold should be solid at that point. Look at the lower intake, I bet it was opened up as well.

On the inlet.. I don't see any porting or cleanup work there. Seems I can see the lips top and bottom of where the plate is put on and then bored just a little off. (Same as all of my cases)

What do the rotors look like, still have coating?

That is done to expose more of an intercooler to the chrged air.

BTW, I've seen ones much worse than this...

well, I'm supposed to be getting the ported GEN V LIM back this week.
Will this help at all considering the size of the ported L32 LIM would be closer to the size of the ported GEN III or should I have the GEN III LIM opened to match the SC outlet size?

You should ditch that Gen3 M90 for the garbage it is. Considering the lack of quality work we can see, I would suspect EVERYTHING about it.

It'* a paperweight. I can't believe this guy has done more than one.
