Tale of 2 Twin Turbo engines (and some others.....
.....500hp units.
Now that I have taken delivery of my 335xi, I have a chance to compare the 997TT and the 335xi's engines.
Both have around the same displacement, both are twin turbo-ed with 3 cylinders feeding each unit. But while the Turbo gets up to 18psi of boost, the Bimmer only does around 8.5psi and hence the ~180hp difference.
Both are awd with automatic but the Bimmer gets a 6 speed unit.
Off the line, the 997TT just simply flies, even without brake torque, there is no lag whatsoever, it continues the lagless-ness all the way thru the gears. While in the Bimmer, there is a little bit of lag coming off the line but once in second gear, it just rockets onwards. I have to say apart from that the 2 engines have very similiar characteristics, but the Bimmer is around 7/10 of the Porsche.
Since the 997TT is my car, I considered it a fair deal that my wife also gets a twin-turbo-ed awd car, but since she is the wife, she only gets 300hp but with a bigger backseats for the in-laws.
While on the subject of engines, the AMG 55 is still my all time favorite, big displacement paired with a roots-type supercharger, instant power everywhere.
The AMG 6.2 is my second favorite, seeing 6.2L worth of V8 revving to 7k rpm is just unreal. The Z06 unit comes really really close, it's almost a toss up.
Best I would consider the Porsche 3.6TT unit is only 4th place, yes it has VTG and racing block heritage but imo the 2 AMG ones and the Z06 one is a little bit better. But it's still an amazing powerplant, matching the hp and torque output of much bigger sized engines.
I would consider the F430 V8 and the V10 in M5 and Gallardo coming in after the Porsche unit bcause they make absolutely no torque down low and needs to rev alot to go anywhere. Almost feel like they have the turbo-lag in a non-turbo car. I think of them as gyroscopes, sure spins like crazy but they don't actually go anywhere.
