Dynoing the W210 E55 Friday...
After searching I found 1 dyno for the E210 E55. We are seeing some very cold temps around here and I figure it would be a good time to get some #s.
My car is an '02 model w/ 24k miles, mods are just a heatwrapped airbox. Next up will be drop in K&Ns and exhaust mods...
I'll be gunning for Mr. Vanos's #s. 320rwhp+ !
Here's his graph:

"We are seeing some very cold temps around here and I figure it would be a good time to get some #s."
Correction factor will account for that and reduce your hp. However, you can run uncorrected numbers and they will be higher in colder weather. Those dyno numbers you posted are much higher than what I've seen on a 210 E55. They are usually between 280 and 290 RWHP.

The guy who posted the #s in the graph is/was an admin of this board and that was the only graph I found.

Sorry for my ignorance, but I am assuming those dyno numbers are not SAE corrected?

No, those are rear wheel horsepower figures. Take the 321.3 and divide by .82 (drive loss) and that would be a good estimation of your SAE crank hp. Most of the E55 210's will dyno at around 280 to 290 rwhp 280/.82 = 341 hp to 290/.82 = 354 hp, so his initial dyno tests are quite high. I'm sure Marcus will share his results with us.

RESULTS!!
296 RWHP SAE (~361hp)
324 RWTQ SAE (~395tq)
Unforunately, we were only able to dyno from 3000rpm onward (since if we punched it lower the car would downshift) and I'm pretty sure the car makes it's peak torque before then. I am pleased with the results, especially considering that a bunch of other normally aspirated 55 cars dyno in the 270-280rwhp range as BlownV8 suggested. It should be noted the car was not altered in any way, no airbox removed, none of that crap. It was pulled in, put on the dyno, disabled the ESP, and let her rip.
I will be putting up a dyno graph shortly.

Marcus Frost, what king of dyno is that?
I must say, that is a lot of HP for a stock car, have you taken it to the track in the past? what have you run??
I can't find the results on my car, but it wasn't even close to your numbers, and to my knowledge I have the best 1/4 mile time on the board for an E55 with the wraped airbox and K&N air filters.
May be I should take my car to your dyno

It's a Dynapack dyno

Considering Mr. Vanos put down 311rwhp on a dynojet I don't think my car was that high. Remember, these are handbuilt engines and will have some discrepancy.

I have been to the strip but because I kept trying to do runs using the TIP I hit the rev limiter on every run. I did manage to run a best trap speed of 105mph, though, but your ET is better.

311 at the wheels is about 380 crank w/18% DL loss...
...I agree, this does seem a bit high, but if it is accurate, you should be able to trap at about 108.6. If you're trapping at 105, I'd suspect the dyno.

I've only trapped @ 105 banging off the rev limiter in 1st... I have never made a 100% clean run.

nice numbers...
I put down 290HP SAE and 302 lbs/ft SAE so your numbers are real nice Marcus...when at the dragstrip I look for MPH as an indicator of my HP... I have run a best of 13.26 @ 106.40 in good weather...but have run a string of 104's and 105's trying to shift the dang thing...should you should be "right there"...with the sounds of your supra this may be the slow car in the stable...

"If anything I'd be questioning how Mr. Vanos got 311rwhp SAE... that to me seems pretty high!"
Yep, that['s really high for the 210 E55.....especially Mr Vanos' "stock" run.

"However I really don't think these dynos in my area have been very accurate because they've turn about 265 RWHP or so if memory serves right ."
Probably a Mustang dyno?

Another was a Jet (or something like that)

"I figured you were on a mustang dyno by the lower figures Pocholin, a "dyno jet" dyno will get you the figures you want"
Well, a DynoJet has become the standard in measuring horsepower at the wheels. It's very simple, very accurate, and results can be compared to others' results in different areas and different conditions without losing accuracy.

Here's the graph.
NOTE - yes, there is a spike on it right around my HP peak, but the peak HP # was taken from RIGHT BEFORE THE PEAK, because the peak is a blip in the dynapacks. If you look closely you will see a little star on the HP graph right before the peak, that is where the peak HP was taken from.
You can also note that my car would have made more rwtq if we didn't have to start so high in the rpm band. If we would have floored it before 3000rpm the car downshifts :-\
