My s2 had a bayjoo chip,mongoose exhaust,pro alloy front mount,uprated actuator,modified metering unit,Kent cam,low miles solid good running engine with correct compression,bleed valve instead of the Amal valve and that made 194 bhp atw on Ava's dyno back in 2005.
I asked why other rs turbos with an exhaust and chip were claiming to be well over 200 bhp and was told simply "they are lying" and my engine was putting out really good power for essentially a standard engine and if I wanted more it would be a zvh or something apart from a 1.6 cvh with standard internals.
If anybody's 1.6 cvh with a turbo and chip are making dyno figures of over 200 bhp then the dyno needs calibrated.
Let's not mix up the measurements here, 194 BHP atw (at the wheel) relates to around 225 BHP at the flywheel once you factor in transmission loss. I'm guessing the 200-250 he is after is a flywheel figure.
You have to remember that a rolling road (aka an engine brake) can only give you an at the wheel measurement and give you a best estimate at the flywheel power factoring a transmission loss. Hence why it is Brake Horse Power (deduced from an engine brake reading) not Horse Power (factual output).
I currently run a stage 1 T3 which is my limiting factor, I only run it at 10psi. My car makes 162 BHP at the flywheel but only 132 BHP at the wheel. The general figure people throw around is the flywheel figure.
