We will be running all day. I plan on being at the DIY and running late in the day after the DIY. You should do the same.

Probably will start at 9:00 am and run in set intervals through the day.

Didn't really have a choice with the conflicting event - it was dependent on the shop schedule.

ok, that'll be a long day. its quite a drive from Manassas to Mt Airy, but it'll get me back on my side of the world :)

now i gotta figure out what needs to be done on what car at the next DIY. i'll probably dyno my 335 since my M Roadster is stock

Correct.
FWD should be fine too, just no AWD (I'm 99.999% sure). Who really needs all that extra weight and that pesky drive train loss from an AWD system anyway.... :tongue:

I was really hoping (probably Jonathan as well) that you'd dyno the roady... we need a baseline afterall! :tongue:

BTW: in.

The shop owner is a BMW club member, so it would be nice to be a BMW crowd.

Oh I didn't know if we had 10 spots out of 20, or something like that. Having a nice presence of BMW's will be nice.

It's a smaller shop, so we will probably run 45 min intervals. He likes to run the cars until he gets consistent / accurate numbers which sometimes takes time on BMW's.

Just realized this is an hour away. I might not bring the E30 then, because that means not hearing anything that day, or put it on the trailer. Do you need to know what car I bring? well, it's either that or the E36 if I get tags on it by then.

Nope. It's not necessary to know what vehicle.

Whatcha doin' at the DIY? You can probably do whatever it is at my house and then we can get started (and maybe completed) with that speaker box, amp and sub install. If you can get here by around 9ish, we can easily get it done and spend some time at the DIY. Maybe if you're really, really nice to them, Sam and Mark will come over to help with the build (and maybe we can finally get Mark's box built too!). I think I have enough wood for one box. You'd need to buy carpet (we can get it at Best Buy), the sub (locally for cheap.... don't bother ordering one), a tube of caulk, and the wiring posts (radio shack). It'll be cheap.

BTW: your amp is in my garage still.

Just remember, you gotta take all of that out to autocross.

Ed was a great guy to work with and I think I will definitely use him again. He took his time to do each dyno and you can see he really loves to work on cars. I hope we set up more dyno days at York Automotive.

So by adjusting for 20% losses, I hit 270 at the crank and you hit 277-ish...

Here's the more specific numbers for my car:

222 RWHP @<hidden> 5800 RPM
222 RWTQ @<hidden> 4400 RPM

George's car:

217 RWHP @<hidden> 6100
217 RWTQ @<hidden> 4200

It's interesting that his car hits max torque 200 RPM lower and acheives max horsepower 300 RPM higher.

Without the misfire, the torque number wouldn't have changed, however, looking at the graph, it's pretty obvious that you would have got around 2 horses more peaking at 6300 or 6400 RPM.

Post up your a/f ratios. I forgot to look at the difference there. Mine was basically staying around 14.2. What was yours around? 13-ish? Per Ed, 13.2 is ideal and mine was slightly rich. Dinan is a conservative tune. That's the real difference between our cars. The Shark might just be worth a few hp more...
