Next version of Cayman/Boxster will include turbo flat 4

It's my understanding that no one has been able to crack open the stock ECU on the current gen Caymans. If the same holds true of the turbo engines that would be super disappointing. Half the fun of a boosted car is the free hp you can get with a tune.

Part of me wants to think the next-gen Porsche turbo cars are going to be a tuner's paradise - and if it were any other manufacturer, that would probably be true. Knowing what I know about Porsche though, they will probably be locked down harder than Fort Knox. Yes, there will be gains to had from intakes and exhausts, but these will be minimal compared to what you could expect from a full turbo reflash.

Of course Porsche could get 400 or more hp out of a small four cylinder engine. But without hybrid assist for down low you're gonna have a lot of lag and crap throttle response.

The mercedes CLA AMG is a turbo 4 making pretty much 400, if not more horsepower. What makes you think Porsche couldn't do it?

The 911 turbo's engine size of 3.8 liters has a lot to do with that. It's pretty reasonable to assume that any boxer 4 engines Porsche builds will be 2.5 liters max, considerably smaller.

Right, so there won't be nearly as much torque or horsepower, but there are no technical reasons why it couldn't be tuned to have a similar torque curve. 2.5L is large for a 4 cylinder and combined with modern turbo tech, it could have tons of torque with little lag.

I've never heard a turbo 4 banger sound anywhere close to as good as a tightly wound NA Porsche flat six.
If you want horsepower/torque, go buy a Vette. People buy P-cars for the sound, feel, quality, etc. A critical part of that IMHO is the sweet revving flat six sound.

You are mis-equating lag with power delivery. Lag is the time it takes the turbo to spool when you put your foot down, it has nothing to do with peak torque.

I just remember that it had a ridiculous 0-60 so figured it had to have at least power figures in that vicinity. Thanks for the correction.
