Crank your volume up

Put the car on a Dyno yesterday at the Thunderhill Raceway track event. Had about 45 minutes to spare; so I drove right off the track after my session and into the Dyno garage across the paddock.

Edit: Dyno results posted below

The entire garage was rattling and my ears were ringing...what a sound the engine and exhaust makes at 8.4 rpms!!!

WOT to redline starts at 26 seconds on the vid. Dyno was run in 4th gear.

Note: This is Eisenmann Sport Exhaust.

You guys would probably enjoy this one too. Engine and exhaust sound great here as well. This was my car at Infineon last Thursday.

Here is the Dyno charts I mentioned.

I would really like it if the tech/engineering guys on the forum could look at the charts and analyze for us.

I personally thought the car would have put more hp to the wheel, however this was literally run within 10-15 minutes after a track session that day....i still had my helmet on when i got to his garage. Temp was 93 degrees, and you can notice that the hp/torque decreased per run, as the car was getting hotter and hotter.

One thing though, the tech was so impressed with the graph and air/fuel ratio...mentioned he had never seen anything like this before on a street car; to the point that he kept calling his buddies and other coworkers in.

Please have a look an let us know what you see

You should get the iphone dyno, it's better.

























i kid, i kid

VROOM VROOM V8 baby. nice

Ya, i need to post the Dyno charts for the math guys to analyze on the board. The results looked very nice, the tech mentioned he had never seen such results. One thing though, i thought the e92M3 would have more hp at the wheel than what my Dyno showed; then again I drove right in there after a run at 93 degree temp!

what kind of whp???

[JEllis]

cool

I thought it would be higher....but I came in at 347 at the wheel and 253 torque. Air to fuel ratio was perfectly on the line.

I'll scan and post tonight. Keep in mind, this was right after a run, under 93 degree temp..the car did not have a chance to cool down.

Dave,

Nice to hear you are "using" your car! love it!

Hey - any issues with limp or cut-out?

You jest, but it works surprisingly well, especially for $12.00!!!!

Thanks

Hey Brad-

No limp mode at all; however several 335's did; and a few others were running very very hot oil temps.

M3 handled like a champ, considering that was the 3 track day with a 4 day span.

Brad take a look at he Dyno chart i have...very different figures from the stock e92M3 you guys had up there. What do you think the delta is from? Believe he had 333 at the wheel vs. my 347?

The difference is his wheels.

See this:


This was the dev car we are using, stock was 349whp.

Vinh's BIG HRE's (tall and wide) with a big heavy tire make a big difference. We guessed it would be about 15 whp, and that is pretty close.

Thanks

Much better...this makes more sense now

Not bad, so after 3 track sessions of beating my car up in +93 degree temp ...I only dipped a few hp/torque figures from your first stock run..nice!!!

Will call you to learn more about the pulleys

What kind of numbers were you looking for? 352 is what the car should put down assuming 15% losses. You are right there, and damn look at that torque, this motor is a work of art.
