You raced a 90kw 1.8 Citi with your 141kw RunX yet?
I raced my brothers Life 1.6i ... redone crank & pistons to a 1.8i ... 276 degree cam and full branches/exhaust (50mm-57mm progressive exhaust) pushing 69.6kw at Snails dyno - roughly 90kw on the wheels. So, yes I have.
Jumps me on pull off (my bonnet to his back door) and pull him all the way to pass him relativly quickly at 100-120km/h ... at which point it's all over. RSI runs away.
When he was stock 1.6 Life, there wasn't umch of a contest. At about 100km/h there were 3 car lengths between us (15 metres) and 140km/h I couldn't see him.
Yes, he's on the VW forum and posted race tales. He's the one with a Gtech, so there are probably full graphs comparing both vehicles (and many others)
