put it on the rollers yesterday for the first time and i'm pretty chuffed. It made 192 horses at the wheels and 356 torques.
2 questions for anyone who listened in school:
1.The guy said add atleast 18% to get the flywheel figure,
2. weighs 605kg's(ok bec crowd its fat!)how do you work out power to weight?

192x1.18= 226bhp at flywheel.

(226/650)x1000=347 bhp per tonne.

IIRC but it's been many years since I left school

I make that 346 bhp/ton if you add your transmission losses.

But I have just got up

I rounded mine down

Where did you get it done ?

thanks fella's.
I'm not good at numbers!

ab in sandycroft.there was a yellow tiger there that he'd been doing a new head on,think it was a pinto,and when i got there there was a 1.9 205 on the machine which made 82 at the wheels so i'm guessing it wasn't a dream machine rr.

Ooh.. I used 650 kg not 605 so it's actually

227bhp (rounded up)

and 374 per tonne.


And 420 flywheel torques, 694/tonne.

That's my tiger!!!!!!!

How's it going?? I feel like it's a close relative gone in for surgery!!

Hi,

I don't know your exact setup but my first gut instinct to 356 lbs ft with only 192 WHP was that maybe that torque figure was actually in newton meters? Just that's the sort of result you might get from a V8 or a diesel.

Just interested that's all as that a big glob of torque to put down in a light kit car! Any chance of a dyno plot scan?

Might that torque be down to the turbo ?

I saw the turbo part but double the torque is quite a difference.
