197 engine

How the fook do renault get 197 PS (194.3bhp) from the 197 engine?

I'm guessing it has fairly good fuel economy and also hits all the emissions restrictions etc as well? and has good driveability throughout the range.

It runs a f4r block right? so what are the diff's between it and the f4r 730 (172/182 engines) ???

its a big block f4r like the meggy 225 iirc. is all i know

"big block" ?

**Justin..** · 09-05-2009, 14:26

yeah its different how i dont know. more of a CS question as they have more owners over there

**summeh** · 09-05-2009, 14:27

im finding CS not very good for hardcore technical knowledge.

not even from 'tuners' ?

big block meaning the bottom end is externally bigger to mount on to the 6speed gearbox

i've no idea what internal differences there are between the 830 and the 730 etc.. :(

oh, the 197 has continually variable valve time, so that might help!
