How many fellow Rennlisters have put thier sharks on a Dyno? If you've Dyno'd your could you list the year, trans & any modifications you've done, along with the HP and torque numbers (with RPM)?

I wonder who is the Dyno king? I know the supercharged cars are just over 500 rwhp with the DEVEK white car at about 550 rwhp? I'm guessing that my 88 S4 auto with a K&N & RMB should put down 250-260 whp, maybe slightly more (it does run real strong).
Thanks

255 SAE rwhp at just over 6k rpm. 255 ft lbs at 4400 rpm. Just mixture and spark tuning with a newer air filter.

Legend tells of a certain low-profile gentleman who forces 26 psi of fuel-air mixture through his 928, but it is not my story to tell...

Brian;

Do a search in the members section under James Komiak. Towards the bottom of his page he has maybe 50 928's listed by HP.
Can't say when it was last updated, but it is a good read.

You would think I would have more pictures of the finished product but alas I don't. Heidi had a ton of pictures taken of her at the track, so I'm sure there are a lot of good pics running around. I just don't have any of them. Here is a couple that I have. One before it was complete:
In Progress

And another after I got it running but I've made some changes since to get rid of the large crimp in the Inlet hose.
Almost Finished

Ugh. That page takes about a zillion years to load. Luckily, the dyno numbers at the very bottom come up after only a few thousand years.

The page has been updated in the last year or three. The last time I looked at it my '91 was king of the hill for nearly-stock 928s. Now it has fallen behind by a few ponies. But, it's still the king of '91s on the Jim's sheet.

And if anyone is paying attention to the sheet... There are two dyno runs for my '91 - one with K&N at 294 and one without at 292. Pay no attention to the 'effect' of the K&N. The differences in the numbers from the two runs was not statistically significant. There's no valid data to support that the K&N added 2 rwhp to my car.

My 87 S4 Auto consistently dynoed 270-275 Hp and 280-285 TQ. All at the wheels, and the dyno runs were done with over 200,00 miles on the motor, never been apart..

Ooops, typo............. 200,000 miles

556HP 495TQ at the wheels with 12.5 pounds boost. I think these numbers put me in the number one spot for dyno verified, highest horsepowered street driven 928.

I have driven about 2500 miles with this setup.

550 rwhp - NA

Darn, I might have to go back to the dyno to get back my spot..
