You've more chance of being struck by lightening...
Dave at Retro Ford has done 4 cars now with ST170 motors, one was standard on throttle bodies and management with the VVT being controlled by the shift light output on the ECU....
Made 170bhp..
The second was his own development car, on motorcylce throttle bodies and management, made 170bhp
The next one was on a similar set up with a vernier pulley on the exhaust cam, made just over 180
The last one had the VVT removed, CAT Cams, Verniers, Bike Bodies, management, made 195bhp
To get the bhp up near 225 you will have to re-work the head, and bear in mind its very nicely done already, a set of cams, verniers and the key seems to be in raising the compression, a decent exhaust manifold and you may have to go to big valves....
But bear in mind when you get to this stage you need to look at things like rod bolts etc to beef up the bottom end a little...
