Deviate gets a K20A2

I think you'd need two stages for a vacuum as you have to pump to a tank.

If its just a single stage, how does it get any vacuum? Doesn't it put in as much as it takes out? I'm interested because a similar setup on a miata might be a good way to get a better oiling system and reduce windage to free up a bit of power.

But yes the primary reason for doing a vacuum pump is to reduce pumping losses and it also allows you to use a much lower tension piston ring. They will then generate a bunch less heat and friction. Piston rings are the primary source of engine heat, outside of actual combustion. This is all pretty standard stuff in NASCAR where vacuum pumps are quite common.

Dunno actually. You could call John at Hytech or just google vacuum pump oil systems to find out more. I did not design or build the system so I'm probably not the best guy to ask.

Anyway back to the K20... damn it looks good. I'm starting to wish I went a similar route with my car.

Glory.
Just got Deviate back from Hytech after over a year of this and that. We're going to powdercoat the red ano AEM fuel rail the same orange as the valve cover. Wiring harness is mostly built. A few days hooking things up then she gets fired up. Shawn Church and Doug Macmillan (Hondata) will tune it in a week or so. We are determined to figure out how to fit the Quaife sequential box in with custom exhaust and modified PPF. We all just for a moment, imagined what this thing would sound like at full song, cracking off flat shifts. OMG. We have to find a way to make that happen. Eventually the QBE60G will go into the OGK but hopefully, not before I have done at least one day at Buttonwillow with in in Deviate.
Oh yeah, decided this car must have 15x10 and 245 VR-1's so we'll hella pull the rears and fit some Carbonmiata fronts.
External line feeds oil to custom cam journal oiling system built into back of head. OEM system can let cams bottom in journals with stiff valve springs and high lift cams
Intake is a specific length although I don't know what that length is. 3" diameter.
Custom Hayward Performance based IM with bottom feed TB
