Rolling road in Hull?

[peterperkins]

I'm after two simple power runs in my modified car. No tuning or tweaking etc.

One with the hybrid stuff off, and one with it on.

I just want a simple comparison of the power outputs in the two modes.

Anyone got any recommendations in Hull/Beverley area?

Thanks

I was after personal recommendations from local car enthusiasts on PH.

"Recommendation.

A suggestion or proposal as to the best course of action, especially one put forward by an authoritative body."

I've been on Google and seen the options.

OK, well if you have searched you will know that there is only the one.

[peterperkins]

Google list's two.

My point is that for what you need any old dyno will do, you don't need a recommendation as you have no difficult or specific criteria to be met.
That's why it's a daft question.

It does, and then just one more click (on the actual website) has no mention of a rolling road.

Both mention their dynos, one has a Rototest 4 wheel drive hub dyno, whilst the other laughingly tells us they have an 'Eddie Current Dynamometer', who is this Eddie Current guy?

Is there anyone left on PH these days who can read properly or know how to use the internet?

Well if one has a Rototest....presumably they know what they're doing. As they ain't cheap.

Could be 'all the gear no idea', but for what the OP wants i'd just be using whoever is cheapest, it's only a back to back test.
Although speaking of which, i've recently seen some ridiculous figures coming from Dynodynamics which I always thought were quite accurate. They're so far out it's like they got WHP and BHP (@ the fly) the wrong way round. I'd be interested to know how you can fiddle a dyno, I keep meaning to ask Paul at RS, but forget. His dyno seems very accurate, he does check it now and again with an unmodified newish car.

If this is at road legal speeds, you can go a long way with some tarmac and a stopwatch and lots and lots of samples to smooth out timing inaccuracies. Add a datalogger if you want to get fancy. There are a few inertial ones which are not very expensive, or you may find something that can log speed from your OBD2.

Dreamscience, they are in Hull with a decent Rolling Road.

Any RR output can be fudged...or screwed up by a bad operator.

Really the numbers mean little...more important is before and after when tuning.

I know, I just wondered how exactly they did it.

Stu from MSD wrote a decent article years ago.

Of course some wrong readings can simply be down to improper strapping, tyres, settings,etc etc
