Oh I absolutely agree that going straight for a bigger/hybrid turbo is going to give bigger results, and a gas flow + blueprint would maybe liberate 5-8bhp for several thousand pounds worth of work. Therefore to most, this is not value for money at all. 99% of people out there are happy with the 'easier' option (again, I fully appreciate we are speaking relatively here!).
But for those people building big power motors, spending thousands on big turbo conversions and the like, replacing manifolds and full exhaust systems, a gas flow is well worth it for a few hundred quid (and although a blue print is over the top, I spend time with people who need reliability too -i.e. race cars). A friend with an old Suzuki GSXR1100 recently rebuilt his engine, complete with a blueprint, gas flowed head, reprofiled cams, full titanium 4 into 1 exhast, and its a monster. It revs sooooo smoothly now, to over 12k and the power it puts out is savage. He does own a CNC firm, so could do 98% of his own work and therefore bought the cost right down. He also built the engine in my old Mk 1 Golf.
Thats the thing I love about cars - I could go completely and utterly skint in the search for perfection, yet still have more things I'd like to do!
