16v's actually have more lower down torque! There is a graph on one of the Stickys.....will see if I can find.
Ive owned 5 8v's, 2 16v's and 2 R5 GT Turbo's.
As Jezza says...... The R5 GT Turbo is incredible fun. My PH1 was quicker than any of my Golf's, most prob' due to the boost being wound up to 17psi.....it did go bang in the end

so I bought another one

I found my 8v GTI's very good cars, a good all rounder if you like. My 16v's all cried out to be diven past 4000rpm which is a bit of a sod sometimes. The 16v is faster. I had my oak green showing 138mph on this private road I know! Speedo was out a bit as Road Angel said 127mph. On the same private road white 8v showed 125mph on speedo and 116mph on Road Angel.
I did find my 8v Digi's excellent on fuel.
