997 GT2 boost pressure
I just posted this on RL so apologies to those who frequent both forums:
Just been enjoying some youtube footage of new GT2 and was interested to see the boost pressure digital gauge reading the 1.4 bar which Porsche advertise as being the boost pressure of the GT2.
I find this a little disingenuous, is it an example of Porcshe marketing beginning to further dominate over engineering ?
1.4 bar is being produced by the VVTs and I am guessing the measurement is taken around the throttle body, further down the intake manifold where the expansion thingy works its magic and as the (cooled) air enters the combustion chambers the boost pressure will be around 1 bar, same as the 997tt.
1.4 bar in the combustion chamber would give a hell of a lot more than 530PS - try 650PS !
So why do Porsche like to talk about 1.4 bar, is it because the number is big and sexy ? bigger = better ?
I don't like it, and feel it is the marketing tail wagging the engineering dog - the boost pressure displayed in the cockpit should be what is entering the combustion chamber IMO.....
Anyone feel similar or have I really started losing it
