Tunehouse - Marrickville

[NYTSKY]

Disgustingly clean dyno cell.

Dont hub dynos read 10% higher than roller dynos?

[The Bogan]

I was under the impression that they are more accurate than rollers, Anyone ?

[Pezhead]

I thought that they didn't have any slipping like a roller can, but there is less inertial mass (e.g. no spinning roller or wheel) so they rely on some other system to create load.

[MBS206]

They create load affectively the same way, but because the wheel is gone, the power reading is not "At the wheels" but "At the hub" as it takes energy to get the tyres going which is then free when only measuring at the hub.

their figures to mods seem to stack up with the expected output on the xr6t forums and mph to mods always seems good. There are other tuners on there that seem to read higher with their roller dynos. So i'd say it seems pretty accurate but with any of these things I guess how you set them up has a lot to do with it.

It cannot be denied that wheelspin or even just tyre compound is a variable, and as such hub dynos take a variable out of the tuning process which i think is a good thing.

that pic of your car in jims dyno room reminds me of that tv show E.R.

Do they tune Vipecs?

[D3bb4]

[DAS KAMU]

hmmmmmmmmmmmmmm might take the gtr there for a pamper

[God_speed]

I can also vouch for Jim Ghelis and also Tony there at Tunehouse.

The workshop is indeed spotless and their standard of customer service I've found to be very good after taking my R33 GTR there several times. They even stayed back very late to repair/replace a wishbone after a bolt had sheared off during a suspension upgrade and we had to do a trip to another workshop and back to get a spare part, before the car was used for a wedding the following day.

Since reading Sean's original post i've been taking my car there ever since. These guy's really pay attention to the little things and always do a good job. Jim knows his stuff on the dyno and shows with the tune on my car.
