is this typical

[NoHachi]

It is once the marketing boys have waved their little magic markers.

In the end, HP is just a number on paper. Its how the engine moves the car that's important.. I once tried to start a thread on typical performance measurements..like 0-100km/h, 80-120kp/h
That would really give a nice impression on how much of a performance gain you are actually getting from everything..and you don't need expensive dynos. Its quite accurate too since most 86's are within 100kg's of each other. (less then 10% variance so no real influence on performance).
How about some people digging that thread up, doing some measurements and posting them on the forums? The 0-100 takes some skill..but 80-120kp/h is near foolproof and easy to do safely and legally on a quiet road.
I would do it myself, but the wiring loom is undergoing some work and I'm having the intercooler piping rerouted.
