It was measured as 230 bhp at the fly at .95 bar boost (extrapolated transmistion loss, pinch of salt blah blah - although this was a reasonably trusted place - Northampton Motorsport). That was when we could keep it in the rolling road. Unfortunaltey the place I went to would not take any megasquirt controlled cars back so I had to go somewhere else after I'd done some mods *, unfortunately they didn't have enough tie down points to keep the car still - I'm pretty sure it is torque steer caused as I've replaced pretty much everything at the front that can flex - anyway the left hand wheel can be seen at full chat to be starting to steer towards the centre of the car (the other one doesn't). The RR guy was worried it could pull the tyre off so he wouldn't continue. * The mods were, removal of two cats, increase fuel pressure, change of the fuel firing patterns, spark and fuel maps changed and other minor tweeks. I re-mapped it on the road myself. Since then the low power setting has felt more like the old high power setting (I've a switch on the dash that switches between 0.5 and 1.0 bar boost, so I'm extrapolating the figures and knocking a bit off to give 250 bhp. Oh saying that it's a different engine now as well, however it's still far too quick. > mind you I don't > suppose it really matters.

You can spin the wheels in any gear if the road is not totally dry - 5th gear 70 mph full throttle in the dry won't though. There isn't a turbo kick (like old laggy cars) as we do have some electronic gizmos - namely a mega squirt which has been setup to control the boost levels dependant on rpm and throttle. Also there is no perceivable turbo lag. I've not done anything totally crazy (yet), but basically anything under 2500 rpm and 50% throttle will only ever give a maximum 0.4 bar boost. It then ramps up gradually based on thorttle, rpm and power switch position. You can do silly things if you floor it in a low gear especially as it will overboost for 1/4 second. Tyres - no idea! Probably longer than when I had a standard engine, mostly because now I don't need to get a head start from the lights - I can wait until I'm already moving enough then progressively open it up. I'm also old enough now that my driving has calmed down a bit (32). > p.s Can I have a shot Depending on what a shot it, I'm sure it can be arranged ;-) I always joked with Jim that once we did the engine I'd need a new RWD car to put the engine into - in a funny way it's true! I've no idea what it is in real world figures (like 0-60) however off the lights it can keep up with a Porsche Boxster S. Nothing more exotic than that has tried.
