4wd on a 2wd dyno..., can?.. Options

[miguelst205]

Hi everybody.... I'm from Paraguay and I have a ST205 JDM, and a friend of mine have a CALDINA ST215W (3sgte gen 4)...

Is it possible to raise the back of the car and just have the front wheels on the dyno. Do the gearbox brake apart or what??...
Is the dyno test on the F-wheels accurate yet??...

The reason I am asking is because here in my country we don't have a 4wd dyno..

Grettings... thanks in advance...

I cant say for sure as I havent actually tried it, BUT I would say with a fair bit of certainty that you will not get an accurate reading as the power is equally split from the front wheels to the rear wheels.

Also, I highly doubt you would find a dyno operator willing to let you use there X0,000 dyno in such a fashion. It would be EXTREMELY dangerous. Have you seen a car run on the dyno? I will guess that you havent, as then you would have never asked this question. The car gets strapped down, so I cant see how you would successfully get the rear (or the front) securely up in there air.

Next, if you are able to secure the car enough safely to get is strapped to the rollers.....have you ever seen what a car does after you have completed the run, and let the gas out?.....I bucks, and it bucks HARD. Enough to knock the car off whatever rigging you made up to hold the other end of the car up with.

Like I said before, I cant see a dyno operator letting you take this chance on his X0,000$ machine. Think of the damage you would cause if the car fell off the rigging you made at the end of a third gear run......you rear wheels are spinning at over 100mph....and a 4th gear pull pshhh, forget it. You are looking at 130+

It is VERY unsafe, and I would look harder for an AWD dyno. Even if that means taking a vacation for a week and bringing your cars with you. There has to be an AWD dyno somewhere in Brazil, Argentina or Bolivia.
