Dyno today!but something wrong???

beckham77 · 01-05-2010, 03:00 PM

the horsepower and torque seem strange？？？

beckham77 · 01-05-2010, 03:01 PM

2009 bmw -002 drf is 3th dyno

M3Newbie88 · 01-05-2010, 03:48 PM

Hmm.. does look strange.. since you claimed with your mods your car should be well over 400hp.. it seems the dyno says its way below.. might want to check that again..

Also are you not selling your car? Or keeping it now since you are dynoing it?

untouchableE82 · 01-05-2010, 06:03 PM

i guess dinan doesnt give you that much power. from what your dyno chart shows i dont think your car is running properly. tq seems fine but the hp doesnt seem proper since you claim your over 400. there are lots of values that can come into play. as to what gear you were in when you dyno'ed. maybe your car is running to rich or to lean.

beckham77 · 01-05-2010, 09:31 PM

I think the dynojet not very good fit my car!I will do dyno for powerhouse!

beckham77 · 01-05-2010, 10:22 PM

There has to be something wrong with this graph:
1. HP and Torque has to intercept at 5252 RPM.. while the HP and Torque in this graph clearly are not intercepting each other at all!
2. Since all dynos measures the torque, and HP is just determined by a mathematical equation.. I am assuming the torque is accurate, it's just that the equation in their machine is the culprit. I made some calculation:

at 5500RPM ~110MPH ~375 tq: HP = 375*5500/5252 = 392HP
at 6000RPM ~120MPH ~400 tq: HP = 400*6000/5252 = 399HP

If that's the case, I think my car is running perfectly fine except the dyno has some calculation problems. Any one has any thoughts on those?

I suspect the dyno may be showing power figures as kW rather than hp... seems to work out better that way (since 300kw = approx. 400 hp)

alimjessa · 01-06-2010, 11:47 PM

You are not to far off in the HP figures, usually Dinan stg 2 will get you 315-320 Whp.
I know cause I have it.

So maybe his torq numbers are wrong?

beckham77 · 01-08-2010, 04:45 AM

I will do the dyno again！！！

Irishace · 01-08-2010, 07:24 PM

Please do, I am curious as to the results. Report back when done!

and please have them them spew out a graph with rpm not speed

Dynojet should report a little more than those HP figures with the mods listed in your siggie, but the torque is amazingly overstated. Agree with losing the Speed, in lieu of an RPM graph. With drivetrain loss, those TQ figures would put you over 500, which is ludicrous.

Are these guys new to doing dynos? Did they set the car's stats correctly before running?
