My mates got a focus ST170 and when my alfa 145 was on the road (1800 16v 144bhp) he could just edge away from me, it upset him more than it upset me.
Now it has an american supercharger kit fitted, powerwerks one but he's on his third engine, this one now has forged internals.
I chased him the other night but hit the limiter in second and third (i need 200 clocks) and, ironically he just edged away from me, just like before but both of us going a good bit faster.
I think side by side and watching the rev counter more than his back end i could possibly do him.
