Hey Guys, just wondering what figures would i be expecting to get on my first time dyno run in stock form? I have the 96 dc2r jdm spec still running in very good condition.

cheers

Why not do a search?

Look at this thread: http://www.ozhonda.com/forum/showthread.php?t=77428

On the first page, someone posted some power figures of the JDM DC2R.

Another source for you from temple of VTEC Asia.

Dyno'ed at 170PS at the wheels.

just something to help you out -

Any FWD will lose "about" 20% from its engine thru the drivline to the wheels.

So , do the math.

147 / 100 x 80 =

117 kw ATW.

Try this on other FWD's too :)

don't u mean 117 Killer Wasps!?!

I think the percentage is a bit more than 20% Ben...

Dave dynoed his stock ITR and pulled ~ 101kw atw from memory...
A variance of 15+kw is a lil too big for a "stock" car yeh?

heez got a jdm dc2r? arent they more than 147?

dc2r, 141 audm - 147 jdm

friends jdm b18cr dyno'd in at 119kw atw, stock motor.

i have an audm dc2r and stock mine pulled 104kw at the wheels.. so going by that and wat was previously said you could assume that a 27% loss is more reasonable to estimate power loss through the drivetrain on a dc2r.

Therefore.. 147kw x 73% = 107kw

so it would be safe to assume that a jdm dc2r would probably pull round 105-110kw at the wheels.

Your single example doesnt back up your theory lol

Notice the term "about" used :) Its an average , some FWD's loose a touch more than others etc. Only a guide ;)
Also depends on dyno itself and software etc etc etc

Like Ben said, it depends on the brand of dyno.

Last dynoday I went to, stock DC5R (147kW) was pulling 110.1kW and S2000 (176kW) was pulling 123.4kW. So that particular dyno was showing 75% for FWD and 70% for RWD.

hmmm, maybe I'm stupid, but I dont see too much logic in why a dyno would produce different readings on a car if it used the rollers at the front, it would allow me to cheat my readings ie, if i owned the s2000, and the front wheel readings were allowing me to show 5% more, then i'd be pretty tempted to put my rear wheels on the front rollers? no? :confused:

most dyno's don't permit you to go on backwards..

maybe not put the car on backwards perhaps?
more to the point, is there some reason why these dyno manufacturers would have that variation in the figures?

I would have thought FWDs should have less power loss atws compared to RWDs due to the power having less components to be transferred through to the wheels?

different dynos will yield different result.
my mates DC2R got 110kwatw, and its the audm one.
as previously mentioned someone got only 104kwatw stock,
my mate had a stock vtir dc2 and he pulled 98kwatw.
soo im just saying that differnt dynos have different results, i think it depends on the humidty and stuff along those line..
so in answring your original question; its not really easy to determine ur kws,

but ddint the jdm dc2r get upgraded at some point? i mean the 96 and 98 were changed from each other if i recall correctly. so just wondering if anyone knows if the kws from flywheel had much of a change too? lol

but for you i would guess around 110kwatw would sound okay for a stock dc2r jdm!!

You can put the rear wheels on the front rollers. But I'm saying the difference comes from the car being FWD or RWD. I'm not saying it's the front or rear rollers. :)
RWD cars have a driveshaft to the rear and a rear diff (open or limited) through which power has to be transferred through, that's why there was 5% more power loss. This is also one reason why Honda uses FWD in most of their small capacity engine cars, there is less power loss and hence more efficient.

dyno's are pretty inconsistent...

brand matters as does how serviced the dyno is... (ie. if the rollers aren't lubricated well enough...more roller resistance...lower power figure)

temperature conditions matter

the best you can do...is compare two different cars on the same day...also always try to dyno your car on the same dyno as otherwise it doesn't mean much

and as was sed b4...
in terms of drivetrain loss,

FF/MR/RR < FR < AWD

this is due to driveshaft size (as well as many other factors)...the longer the driveshaft, the heavier, and thus the more energy has to be used to overcome the shaft's inertia..
