Dynoing A Tt On A 2wd Dyno

[Brumby]

Hi Guys,

This my first post so Please go easy on me I have try searching but I couldn't find any info

I am looking at buying a Territory and I am wondering if there is away that they can be run on a 2wd dyno I.e drop front drive shaft or similar...

Thanks in advance

you probably could mate, just pull the front shafts out - can't say I've ever heard of that happening though

Could be done as Senna has said but why?

All the associated costs/effort used to pull them out might as well go toward the costs of locating/travelling to/using a 4wd DD Dyno. I'd imagine that having the AWD in play whilst tuning would be pretty important as there would be more load on the engine rather than just having 2 wheels hooked up. Could cause problems with the tune when all wheels are being driven on the street after a 2wd tuning session... Ie pinging, torque limiting, limp mode

Hi,

Thanks for your reply, My brother in law has a brand new 2wd1000 mainline dyno and the closest 4wd is approximate 9 hrs drive ( 11hrs for a Mainline which I would pefer) which it is not worth it when I can do all tuning on new dyno. I have had a few awd/fwd cars eg Gtr that I have be able to remove front drive shaft allowing to be run on 2wd dyno hence my question. Im just wondering if it can be done. If it is not I will just buy a 2wd and do a engine swap but I would much pefer a AWD

Thanks

There's a few guys on www.rexnet.com.au that have their awd rex's tuned on 2wd dyno... No problems with it, but won't give a true awd power readout (rwd gives more power)...

Thanks mate, Yes I know about Subarus I used to have a b4 liberty auto and the sti motor/auto in my old brumby it was as simple as fitting a fuse to enable front wheel drive only for the auto version or fitting a dummy shaft to the centre diff in the manuals, I was hoping it was as simple as that or gtr.

AFAIK you cannot do this or the disconnected shafts will just free spin.

There is no locked ratio between front and rear and no LSD for the diffs.

I have managed to get my TTG to do a single wheel burnout before when pushed.

I would check on it more before trying as it could also potentially damage the drivetrain.

Call up one of the Sponsors and ask for their opinion.
