4. No windage problems in pan as no oil sitting in crankcase
In addition to lower center of mass due to a lower engine, there are a few other advantages of a dry sump. Dry sump systems give you the ability to adjust oil pressure, and are easier to add more oil coolers. The primary performance advantage is because of a decrease in windage losses. Basically, without as much oil in the oil pan, the rotating assembly is not sitting in a pool of oil and spin more freely. Also, a dry sump system creates extra crankcase vacuum which increases ring seal.

A dry sump system will cost a lot on these motors and unless you're building a dedicated high-dollar track car, i'm not sure if the investment is worth it. Here's the kit from Turner:

without different motor mount set up how would dry sump help lower the engine mass? main advantage is just the windage as mentioned.

A dry sump setup allows for a much shallower pan. With a shallower pan, you have much more clearance to lower the motor down (Yes, that means new motor mounts if you do want to lower the motor down). The dry sump system itself would not lower the center of mass, but because of the shallower pan, it gives you more room and allows you to run the motor lower in the car, which in turn lowers your center of mass. A dry sump setup does not cause a lower in CG. The ability to lower your motor because of a shallower pan however does.

Hey guys, my media guy is at the dyno now - he will be putting updates on Facebook as they happen. Let's hope it all goes well

Preliminary report says: 540hp, 395tq.

12.5:1
mild cams
100 octane

built for 24hour endurance race.

If we were building this for sprint racing (higher compression, aggressive cams, more octane, OMG.) That will be next

Pics/vids/more info in a few days.

Holy shit! 540 HP sounds good to me! That's about as much as I'd like to have (don't want an SC, especially without an intercooler).

Nice results. What is your estimate of the power level on regular super unleaded 91 or 93. How about some pricing information? Please no "PM for price" BS...

I think some people are wondering what the eventual side-by-side stroker motor comparo will look like, along with price variances.

I'm no engineer, but I wonder if it's more efficient to extract power from a lower displacement 4.4L vs. doing less modifications to 4.6L to get similar gains.

i believe they chose a 4.4 over a 4.6 to keep the high revving characteristic of the s65. The higher the displacement the lower the redline

Ah, I see. Thanks. I didn't realize the DINAN motor doesn't rev to 8300 rpm any longer.

We hit peak power at 8200 - power drops off pretty good after that.

Peak TQ at 5900 - TQ stayed pretty consistent till 7500 or so.

That's crank power right? What did it make on the wheels?
