Nice one, Matrix. I so understand your charger versus turbo dilemma as I went thrrough exactly the same thought process a little earlier this year. I don't think there is any one best solution as it's a personal choice and each has its merits. I guess I smiled a little when you focussed in on the Harrop before you went the turbo route as the Harrop is what I now have.
Isn't it true, though, that the real benefit of going forced induction is it's what many of us knew the car needed? It was great in tuned NA form, but the chassis is so deserving of more power and I was fed up with being left behind by hot hatches. That doesn't happen any more. Just as with my previous car, I don't use the power very often, but when I want it, it's there.
Happy turbo power!
