Bhp @ the wheel

[tricky nicky]

Does anybody kno what a standard 172 cup makes at the wheels?

I am having a laugh with a mate as he just brought a Subaru wagon and is worried as it makes 25bhp less at the flywheel then the sedan. Told him not too worry about it as flywheel readings are meaningless and it's more about gearbox ratio.

He asked me what mine makes at the wheels and I've not a clue

I'm gonna go with between 150-155 at the wheels. But I have no actual clue.

Mine standard was 138 i think, 158 at the flywheel

 

[twingors]

Mine standard was 138 i think, 158 at the flywheel

that it?

 

[tricky nicky]

After a search, found a standard 182 rr print out which gave 150 at the wheel so I think it would be safe to say around 140-150.

Thanks for the input guys

Can be anything from 130 to 150.

With a subaru impreza you loss about 16% bhp from flywheel to wheel power, think its about 8% with the clio.
If that helps.

more like 16% loss on a clio fella

 

[rob_clio197rs]

around 140-145 at the wheels for standard

This is what i was told before? So say a std 172 would make 144 bhp, @ the wheels. Not that any of them have 172bhp or 169 ps what ever its measured in?

 

[Fred@BTM]

well

144 x 108% = 155.5
144 x 116% = 167

generally all 172's make 160-168 @ flywheel for a good one (low to mid 140's @ wheels)

but there's loads of variables and all sorts thrown into it, fly figures are a calculation

take my car for example

160@ wheels = 190@fly

which is 18.75% if my maths is working

 

[conneh]

Wait dunno where i got that from lol!

190 - 160
160

= 18.75%

flywheel bhp is just pub talk.....

that was my point.

the buggati veyron has circa 3000bhp at the fly wheel and scoffs f4r engined 5gt can do the 1/4 quicker

My standard 182 mate 176bhp on live rollers..

That must be around 148-158 ATW

 

[Fred@BTM]

150 @ wheels is about the best you'll see from a stock 182

 

[Poopensharten]

I agree Fred, i only got my car RR'd to make sure it was timed properly (cambelt just been done)

It only matters if the car feels right for you.

Ive said it a few times but if your car reads low your cars f**ked, if its high, the rollers are f**ked...! Cant win...!

 

[Fred@BTM]

powerstation's graphs are the best 172 @ fly = 125 @ wheels, go figure that one out!

 

[Poopensharten]

There must be a racoon eating the other 47bhp... :S
