Roadrunner Chapter/BMWCCA Car Show and Dyno Day
Roadrunner Chapter/BMWCCA Car Show and Dyno Day
The Arizona (Roadrunner) Chapter of the BMW CCA had a car show and dyno day today at Good Speed Performance in Scottsdale, Arizona. Below are some pictures I took early in the event (many more cars showed up a little later). Some interesting cars there, and (just for fun) I've thrown in my dyno results as well. Enjoy!

Before the run, they said they were expecting a corrected wheel number around 420. I was pleased with the outcome:

Actually, that's the intake housing that replaces the factory one when you install the ESS supercharger. But, you're right, it looks incredible.

I just read up on what the "corrected" number means - it takes the "wheel" number and standardizes it for the impact of atmospheric issues (i.e. temp, humidity, etc.). That way you can compare this number for all cars run on a dyno in different locales. So, to put it in other words, my car sends 447 to the wheels under the *ideal* atmospheric conditions according to the SAE.
Nice pics
FWIW, the S85 M5 V10 was "inspired" (BMW press statement) by the BMW's family of F1 3L V10 engines (N41, P80, P81, P82, P83, P84). All the F1 engines racing from 2000 to 2005, when after that V10's were banned. No doubt BMW's F1 program probably influenced the new gen 5/6 getting a V10.
The S85 and the F1 motors do not share any major components (block/heads/crank/pistons/...). But that is a good thing since the F1 motors were only designed to last ~500-800 miles, are load bearing structures in the chassis, and have up to 19.2K redline and 900+HP. Hence a BMW F1 motors only weights ~200lbs and the M5 motor weights ~500 lbs with all their ancillaries. The S85 is a road car motor that is designed to last 100K+ miles which is a very good thing.
The two motors do share alot of technology and common design themes. Both are 90o, all aluminum, Mahle pistons, closed deck lower block, alot of oil scavenger pumps (IIRC 4 in the S85). The F1 motors have pneumatic valves which are not practical for road use, but the S85 also gets VANOS which is illegal in F1.
The S85 is a amazing motor with it's power and redline. IMO one of the two best motors of the 2000's, with the Ferrari 458 V8 being the other.

Thanks for the compliment. The at-crank torque on this engine is only 384. The engine was based on their F1 engine that was never used because of the change in the rules that eliminated V10s in competition. So, it's super-high revving but not very torquey.
As I understand it, the "corrected" number is at the wheels to account for the impact of the dyno itself. The engine is using every bit of the 507 at the crank.

Dammit, every time I see a euro conversion on a E28 it pisses me off because I want to do that so bad! Although, I do have those same E38 wheels that the red E28 is sporting.
Plus, I know it is a matter of opinion, but that E24 is way more stylish than that 335 and should have taken the award home.
Great pics by the way!
