Default Center Diff vs DYNO

Did someone have a picture or the instructions to modify a Center Diff transform, to transform a AWD Suby in FWD to pass it on the Dyno???

Need help!!!

ummm there's no need to transform an orignally AWD vehicle to 2wd for emissions, if they can't test it via OBD-2 only then why would they be dynoing it since it has an emissions expemtion??

Manual or auto tranny?

If its manual, there is no way.

If its auto, the 'FWD' mode is only for towing purposes, and only for short distances. It will not work for dynoing your car.

Sorry!

There are a few places who welded up a diff to use, making the car rear wheel drive, I believe. Mostly shops though, who did it just for their own dyno purposes. I don't believe I ever saw one for sale or directions on what they did.

Where are you located OB2? I'm sure there has to be at least one 4wd dyno within a days trip.

if an AWD dyno is not avialable it exempt from the IM240 Dyno Portion of the test, in illinois there is no AWD dyno available.

Actually a company did make a kit to lock the front differential in a way to push all power to the rear only, thus making it RWD.

I think it was Jun or Cusco, but i could be way off. If this is just so u can get on a Dyno, just take a road trip to the nearest one.

If i told you a Kit was 500 dollars... save the money and do this:

Drive to an AWD dyno... 500 bucks could pay for gas, a dyno run, a night in a hotel, and some expensive booze. With the money left over you might be able to buy a hooker.

If your tuner does their job and makes you happy but also charges you, does that make them your hooker?

there is a company that makes an adapter.. but I can't remember what it is. It is something like superchips, or car chips or something like that.. The company specializes in powerhips, but I know they make an adapter toi take an AWD on a 2WD dyno.

Wow, that's a lot of missinformation. Find a trashed center diff, weld that sucker up good so that it can't divide power anymore, reinstal and don't bother puting the driveshaft back on. You can do all of this with the tranny still in the car. Your car will be front wheel drive. This is what Cobb did before they had an awd dyno.

but you cant drive around with the car like that or it will leak trans fluid.

You could leave the driveshaft, and pull the two front axles... RWD
