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!









Heavily Modified Track Car:






M3 Race Car (this was CRAZY loud):

The folks from ESS were there discussing their performance upgrades:

An '83 Euro Spec 6; the 335 next to it won Best of Show (it was immaculate and he's got about 30k in mods):

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

Very cool! Great pics!

I should have mentioned, for those who care, the dyno run was on plain 91 octane fuel.

Couple of pics I forgot last night.

A very nice '73 2002:


Output from this Turbocharged E46 M3 - 800+HP:

It wouldnt be a Bimmer without guys parked in handicapped spots!!

Looked like fun though.

...not to mention parking on the sidewalk. Typical BMW owners.

MELIKEY alot!

Very nice.

Im actually very surprised the torque isn't as high as I would have thought.

I didnt know the E60 M5 had a redline at 8k... interesting.

Corrected wheel hp, is I take it hp at the crank right?

What does BMW say the hp is? I though it was 500, no?

Impressive numbers, Your car is fucking gorgeous.

That engine cover on the red M3 is gorgeous!

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.

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

ttribe

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.

Sweet pictures, love your m5.

wish i was rich enough to afford used m series.

ttribe

Thanks for the compliment. But, I'm not rich, by any stretch of the imagination. I just happened to score a really good deal 7 months ago when I bought the car used.

Crazy Bimmer

ESS FTW!

Love that E24 as well.

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.

Looks like a great time! All the cars look very nice, but I'm a sucker for the older bodies. '80s FTW.

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!

Yeah your M5 isn't torquey at all, especially when it's nearly going sideways drifting down N. Scottsdale side roads or 100mph+ on the Loop 101. Totally pathetic.
