BHP at flywheel?

[DaveDreads]

I'm filling in a greenlight online insurance form and they want to know what the BHP is at the flywheel.:S

I was tempted to put 172bhp but I know thats wrong,
anyone know what the standard BHP is on a 172?

No two Clios make the same power, the 172 is PS.

The only way to know for sure is rolling road it, why an insurance company would ask that is strange.

 

[Gardus]

I think they want to know the claimed figures so its 172 PS or 169 hp...

 

[Fred@BTM]

just write standard?

 

[Struggler]

Book power i believe is 170,

but from experience, theyre normally about 160, varies completely from car to car depending on how its been built/treated

what a stupid question to be on an insurance form,

 

[DaveDreads]

It's for Greenlight and the box is only big enough to write a number in.
I'm thinking of puting 168, isn't that was 172ps equates to?

It is mental to ask for BHP at flywheel, whos going to know that without a dyno and the correct
percentage loss to the wheels?

even a rolling road wont give you a sure answer!

they read the power at the wheels, then use a complex algorithm to calculatr the drag of the unsprung weight and transmition!
this will always have a degree of innacuracy!

only way to know for sure is to lug the engine out and rig it up to some form of dyno to measure the power output!!
and even then the figure will vary depending on so many factors!!

can you not state STANDARD ?

 

[DaveDreads]

can you not state STANDARD ?

Nope, the box will only let you type numbers.

 

[Fred@BTM]

unplug the lambda, dyno it at 130bhp = cheaper insurance

 

[DaveDreads]

Sod it i'm just going to put 160bhp. (Wishfull thinking I know)

Im well aware, Dad.

 

[Skeeter]

If its standard, they want the manufacturer figure, which is 169.

 

[DaveDreads]

What gets me is I could say 130 or 172bhp, if the car gets written off the're never going to be able to check it.

Most insurance companies just ask if it's remapped or not, exact BHP figures will always be inacuracte
unless they have their own rolling road.

You'd think a modified car insurer would know this?

 

[Struggler]

get two quote, one with 160, the other with 172, and see what the difference is!
