Flywheel figures are always a bit hit and miss. I would only go by the at wheels figure, which for cams with minor mods should be in the region of 175bhp@wheels.
A std supercharged zs 180 with no mods whatsoever puts out 190bhp@wheels adding filter and catback exhaust sees this climb to 210/215bhp@wheels.
Never the less, Steves throttle bodied car should see 190bhp@wheels.
