JDM6MT vs 4AT Dyno Shootout
 

[http://rxreviews.wordpress.com]

What happens when you have 2 club guys with new rides and a lot of spare time? A Dyno shootout of course! Run at ST Powered just a few days ago, we’re pitting a stock, brand new JDM 6MT against a souped up JDM 4AT. We’ll also contrast a previous run done on a stock 4AT as baseline.

JDM 6MT: Mostly stock, HKS Hipermax II, Knight Sports ECU Remap
JDM 4AT: RE headers, Fujitsubo exhaust, HKS open pod, battery relocated, Cusco suspension and braces, etc etc
JDM 4AT baseline: Stock

THE RESULTS (crank):

JDM 6MT: 202.3 HP
JDM 4AT: 160.1 HP
JDM 4AT baseline: about 140 HP

Thanks for the info. :)

wonder how will the JDM 6AT fare...

Go ST Powered, pay $60, then post here or my blog lor ;)

bro, ST powered dyno is at CRANK... not wheel...

HP results also at CRANK.... if u have to see horsepower at wheels, i tink the 4AT owners will cry.... they have a formula in their computer to calculate...

ok..ok.....just dont make me cry again!! :mad:

waaaa...at crank ah?...tat mean at wheel is 183.6hp for the jdm 6mt cause i know ST Power correction factor is 1.1 and for the poor 4at is 145.5hp.......DO DO DOO DO DOO

i can feel for the 4AT owner............................................. ....................................

yeah, i wonder who is that Blue 4AT owner?

Its amazing how much loss auto transmission can contribute to a car's potential. But that didn't stop me from buying one bcos I know that I will not be tracking so often so buy 6MT also lppl. I will also be less worried with my wife driving a auto. And I save 20K for optional parts which I don't require.

But it is just a matter of time. Hopefully there will a compatible sequential or DSG transmission soon. And I'm sure you know how fast it can shift compared to manual.

I'm feel so blessed to drive an 8 everytime I look around me when I drive. Power is never enough, even if you've got 300 WHP. :)

Ps Coupe07, hope you can find the sequential gearbox. Sure can cheer up a lot of 4AT, and hopefully make a lot of money in the process.

Start saving up for these sequentials:

the blue 4at owner onli got afew lor... dun like that can... sad leh.. i wan change my display pic already la... i saw this car than i took a pic of it.. nice rite?? not my car lor...

actually its 161 not 160.1 u idiot...

ya lor..cannot be ur car since ur car is the fastest 4AT...kekekeke

As long as you use a chassis dynamometer which applies the resistance to the wheels, and not to the flywheel of the engine mounted on an engine test stand, it's whp, isn't it?

Anyway, the ST Powered site says they have a 'new 4-wheel dyno', but I haven't been down there myself.

I will go & try once i fully run in my car & change to syn oil. :hahano:

no, its crank, but the system can help u calculate whp.....

4wheel dyno, means can be used to dyno 4 wheel drive.....

i think the question was since it is a wheel dyno, it would make more sense to present whp info rather than estimating driveline loss and translating results into crank hp, which at best are just estimates since the system would not be able to calculate driveline losses accurately.

in short, the results should present whp and the system can attempt to estimate crank hp (in order to compare with manufacturers' figures).

according to one of the shootout car owners that did it at ST, its whp.

crank lah... confirmed stamped guarantee..... check with ST power if u wan the answer from the horses' mouth.....

u check with owners of car, of cos say wheel... cos u can see ur wheel spinning on the roller.... but the fact is, the system gives u your hp that is on crank and that is a realistic figure...

as for why this why that.... i not so technical to answer...

ST says its crank, i take it as it is... their system can calculate whp, i oso take it as it is..... i did not go ask desmond soh "why ur system calculate crank hp when the wheel are spinning on the rollers"...... end of the day, we go there more for tuning using the dyno rather than gunning for hp figures.

bro....out of curiosity...at what gear was the figures achieved? esp the 6mt.....

Sighz... is all i can say...

183whp with remap for 6mt ....do do doo do doo. (I prefer you without car) haha
140plus whp for the 4AT....do do doo do doo.(Bro ur secret proj will give u at least 160whp..dun sad) hehe

do do doo do doo will bring you more horse...

4AT with full NA mods, spending 10k+++ .... only 140+++
Guys, nuff said - you want power, just go straight to FI, dun need to waste time on NA mods.

But it still can't beat the fun factor of slowly adding mods over time :)

wha lan... i believe that 4AT owner is not HORSE power lo.. is PONY power so he still need to feed the pony and wait for them to become horse la... lol

lol...true true -- this one malay call 'badan maciam harimau, tapi konek maciam tikus'
