So lemme get this straight - it's $55 now instead of $35 for three dyno runs? I might still come out, but I think I'll just spectate in this case. I just don't care that much to get a baseline.
It's still $35 for 3 runs, but $55 for 3 runs with A/F ratio.Quote:

OKay, in that case I'm still interested in doing three runs with no A/F.Quote:

I cannot make this dyno day as I will be refing hockey, but I would love to do one soon. I'm very curious as to how much power my 1.8 swap is making, especially after rebuilding the bottom end/seafoam and major tune-up. I can't keep the throttle off the floor now! Runs so smooth and pulls great, love it! :burnrubr:
Crap. Wish I would of seen this before the actual event day...
Great to see everybody. It was interesting to see what kind of power we were making. Congrats to jrj512 for "lowest dyno of the day"!
Dang it! No "till" time. It would be 6 before I could get up there. Guess that's what I get for not reading the forum yesterday. ::Censor::

Hey, at least I got a Hooters gift card for it. It just takes me longer to get there. ;)Quote:

Eddy currents dynamometers (like today's) aren't very comparable to inertia-type (Dynojet) numbers. By comparison, a stock RX-8 would typically dyno around 185-190whp on a Dynojet.
bzzzzzzzzzzz.....wrong, but thanks for playing! ::Daisy::Quote:

Yeah, I wouldn't put even bother posting the torque numbers. According to the printout I got, my car made more torque on the dyno that it is rated from the factory at the flywheel. :?
+1 ... those torque numbers were all over the place! 50 ft. lb. difference between mine and POS's car. 30-40 between miatamoto and myself. :confused: Don't have much faith in the HP numbers as far as that goes either!Quote:

Yeah, the torque numbers were pretty bogus.
the HP numbers are not that accurate ether =/
I thought my HP number was about right.
Cue Sammmy! :mrgreen:Quote:

The folks at Import Car Center put together a nice day! ::Flag::
I did a search on google for "Dyno Dynamics vs. Dynojet" and found some people that said that the dyno dynamics reads about 17% less than a Dynojet. Also the Dyno dynamics reads about 33% lower than the flywheel HP rating.
That puts my 99 HP at around 116whp on a dyno jet and around 132 flywheel HP. All of that sounds pretty realistic considering my mods.
Of course the 17% and 33% numbers are anecdotal internet data. Take it with a grain of salt.
Yikes, if the torque was all over the place that sounds bad. I dont know about Dyno dynamics, but does the dynojet just measure the torque and then compute the horse power off of that?
I think so. A Dynojet is an inertial dyno - there is some fixed mass in the rollers (usually water), and the torque is computed based on how long it takes your car to accelerate that mass. Since the mass is fixed, the calculation is pretty easy.Quote:

I wanted to thank all you guys for comming out, you all made this dyno day!!
Thanks for a great event I think we had all had a great time. It was a good chance for all the autocrossers to hang out during our off-season. I would look into the inconsistent torque numbers though. That's definitely something that keep me from coming back to the dyno.
BTW, big thanks for actually giving out the "lowest HP" prize! I was just joking about that.
Again thanks to everyone that attended. We are planning another dyno day for Feb. 10th. Aside from the torque # thing is there any changes that you would like to see made or anything done differently?
Chili for the hot dogs?
