Ed's Dead Diablo Ph3 GTi6

Ginge; I'll let you know what effect the 'cooler has, but from what I've heard a 13row (what I bought - comes as standard in that kit I bought) is more than adequate for fast road and some track-use. You obviously get more out of it if it's well ducted, and if the car is lighter (ie not labouring pulling more mass about the place). I know some tend to opt for 16row for more serious track-abuse, but i'm only going for light occasional stuff, and predominantly fast-road.

In regard to the decent mapping, yes decent injectors and mapping are mega-important for turbo cars, I think Ruan's point was more that at a given throttle position and rpm, the Supercharger will *definitely* be supplying 'x' amount of air. There is no variable for this. But for instance if you clutch-kick a turbo'd car, and get it boosted up lower in the rpms, it could make full-boost at say 2k, whereas it's not been mapped for this level of boost at 2k, and in normal driving you wouldn't get it there. So at that point it leans out and can melt stuff. It's far more complicated to get the turbo set-up right.
And I *think* this is where you need forged pistons, to take the extra heat etc? But I am guessing at this point! Ruan will I'm sure be along shortly with an appropriate reponse
