Fantasic work, the paint looks great. Did you paint it yourself if so how did you learn?

I expect final weight will be in the reigon of 1050kg. I've given 500bhp as a target, but knowing the engine builder, this will be more likely 520-550bhp. I found a link to a performance calculator:Power at Flywheel (BHP) : 525Weight without Driver (KG) : 1050Power to Weight Ratio (BHP Per Ton) : 508.030 - 60 (Secs) : 4.010 - 100 (Secs) : 7.8160 - 100 (Secs) : 3.80Quarter Mile (Secs) : 12.08Terminal Speed (MPH) : 124.36Drag Strip Quarter Mile (Secs) : 11.88Drag Strip Terminal Speed (MPH) : 126.63The 1/4 mile related stuff can be ignored because its not going to be set up for that, but in-gear times should be reasonable. I'm in the process of building another custom gearbox with theoretical vmax of 218 at 8000rpm, so I at least hope to nudge 190 (current official best in the Mk3 is 184.4 at Bruntingthorpe).A cage isn't needed from a structural integrity point of view, although I suppose it would have been sensible to put one in from a safety perspective. I want to keep it looking as unassuming as possible.Edited by mwstewart on Saturday 12th March 12:13 Nice project, but i think expecting those figures from a fwd car is a bit optimistic!(not to mention a genuine 500bhp from a zetec is actually quite hard, and what transmission are you going to use to withstand the torque??)(please don't think i'm knocking it, but i have a car with similar performance stats, it's rwd, and the transmission system alone cost £22k.)
