This is exactly the argument why I will resist a conversion to TB. As fantastic as the full racing package is that your great 4/4 had, my 4/4 also offers 150 HP with normal intake and a nice torque with smooth sound that lets me drive to Italy with pleasure.
I might not talk like that if I hadn't had a P4SS for two and a half years. It was great but not for everything, and it was annoying for long distances, at least to me.
That's very thought provoking Heinz. I cannot recall what you have done to your car to obtain such a healthy power figure? was that measured on a dyno? I have been pondering getting my 4/4 Sigma on a dyno/rolling road tester to see what the power figure would be following upgrades. I have a Wolf ecu re-map, 200 cell cat with aero racing manifold, cold air-scoop into standard air box with K and N panel filter, iridum plugs, upgraded leads and Millers triple ester racing engine oil. I had hoped it would be around 135 bhp but I see a similar equipped car at Allon Whites is being quoted at 127bhp which surprised me. My car feels very lively, far more so than when I first got it ( 115bhp factory figure) which is very satisfying and matters more than pure numbers. Still keen to know the bhp however - but until a dyno session I have no real way of knowing I guess.
