Not a tuner as you know but 170.2 ATW

[Mike@Rentech]

Really pleased with that figure, done on Dyno Dynamics RR as well.

Mods are de-cat , loss of air conditioning and power steering.
Everything else is standard (182 engine fitted).

Now from you RR experts out there is that a good reading???

Thats a very good reading! 200+hp Fly.........

ATW?

at the wheels

Well it pulls like a train, I drive a lot of clio's
I knew power steering and ac drained power as we all do.
Missed the airfield day due to unforeseen circumstances so missed my real test against other 172's and 182's.
I know RR results are to be taken with a pinch of salt from what I have read.
I had my car 4 up this weekend with a boot full of luggage and it pulled as well as a standard clio.
It pulls so much better than it did with the throttle bodies.
I forgot to mention the exhaust is not standard either

Impressive mate! You know Clio's so Im not doubting the figure either TBH....

Thing is I am, seems really high to me:S

 

[skinner]

At what rpm?

 

[Mike@Rentech]

ATW is the most accurate way of showing it other than a hub dyno or dyno cell. Fly figures are calculated so I dunno how it can be over estimated?
Obviously RR's arent accurate but they have'nt calculated anything.......in theory, lol.

so if rolling roads aren't accurate, what is?

Engine Dyno

Janspeed across the valley from me have one but I don't fancy taking the engine out to see !

 

[Chris n nic]

Does seem odd as you say mike. There is something a miss there as there is no way that loosing the aircon/steering would give 18bhp. I know that DD rollers are good (and tbh they are usually under reading! ) but there has to be a interfearing factor somewhere imho

Compared to the results we had from the RRD on teh same rollers a while back thats a very high figure, sure it wasn'y 170 at the fly?

 

[LegoHead]

18 hp increase is about 13kw. I really can't see the power steering and air con using that much power.

must be a combination of things and slight error on the dyno.

How does this work? Obviously i could never be arsed to do it but never heard about it.
