Did they tell you what type of oil was used in the SC or did they stick with OEM?

Thanks, they did not tell me what kind they used, I'll ask next time I talk to him.
Re: Supercharger Upgrade
Looks great, I think all that work would really shine with a bigger throttle body. I assume he couldnt do anything with it because of the mounting area on the supercharger being too small, or is there no room in the throttle body itself. We have 74mm stock right can we get 78mm??

I agree, as you can see they did open up the back half of the throttle body outlet to s/c, just not the portion with the flap, so I'm hoping for some good air flow through there anyway.

I bet you could get it done pretty cheap compared to other options that are out there. Since I paid $2800 for everything!
That is much subtler than the 240 moded IM's. But I am happy and will likely have similar results. I wish I had all your other port and polishing too....

Re: Supercharger Upgrade
Just thinking outloud here and please do correct me if i am wrong. Our supercharger are posive displacement so the air flow is fixed based on supercherger rpm and displacemnt. I can see a defective or worn out supercharger increasing cfm when rebuild or clearances tightened up.I don't know what the oem specs are but i am sure it's very small gaps maybe.0005" to .001" so not much air can leak by.You also have to keep in mind that the centripical forces increase as rpms increase so the rotor grows and tightens that way also. I expect that you may see some improvment over 20 psi vs stock. As far as ported heads and other clean up i expect that is where most of your new power will come from. a rebuilt super charger, ported heads and other stuff reworked for 3200.00 not to bad as far as cost. however $3200.00 could have bought a nice turbo or a eaton 1900 tvs.

Looks like the silencing slots were left alone, as well as the inlet edges of the s/c. Have you installed the parts yet? Im not sure those moddified manifolds will clear the fuel rail.
And i dont see any throttle body in the pics.
