You're exactly right, it is all in the tuning, but that is assuming that there is a temp sensor in the intake tract somewhere. If there is no temp sensor, the ecu has no way to compensate for the difference in intake temperature after the system heat soaks. Your intake temps are then pushing far beyond ambient, and your tuning then becomes useless. Also, an intercooler is NEVER predictable on intake temperature. That's why there is a temp sensor in the system.
So again, my question is, how are intake temps being compensated for?

It does have a temp sensor...it's in the MAF. All the tuner has to do is tune to the IAT. There is a predicatble efficiency of the aftercooler at various temperatures, and, taking that into consideration, along with the other engine parameters, is all you need. It is nothing more than a caclulation which is the way your stock Porsche is done.
Of course the temperature of the intake after the aftercooler is predictable.

Does the intercooler have a separate water system than the motor or does the air/water have it's own water pump?Is the pump electric or belt driven?
Also, are these kits twin scroll/non equal length (obvious)?
Would it have been better to position the turbo more in the center to equalize the exhuast pulses and to make a true equal length twin scroll with dual exhaust tips and cats?
I am interested, thanks

The question was "is the radiator included in the price". The answer is the radiator was not included in the price of the cayman kit. You asked the question.

Casey - great work guys up there at TPC. Kit looks sick. Is that John's car (aznevoii)? You guys do great work for sure man. I didn't even know there was a thread on this cuz I'm hardly on the 997 section, but I got like 4 PM's saying to get on since I was also getting a twin turbo kit in my 996 4S....hahahahahahaha. I knew my ears were ringing for a reason cuz it looks like my name's been mentioned a couple times. LoL
Looking forward to the final product guys. Keep up the great work brother!

they berk,
this is my car!
I am sure it will be a close match since yours is 996 with TWO TURBOS and mine is 997 with one BIG TURBO.. hehe

Good looking so far, Casey! Wondering if I should have taken you up on the guinea pig offer, or done what I've done: buy Stacy's modified, tried & true SC. I am hoping, perhaps expecting, 425 NETRWHP from the SC kit with my car, mods, and LWFW.
Very interested to see how it all goes, all around. One thing is for sure: we're in elite company to even mess with this stuff.

Hahahaha
For sure, b/c without any turbo's in either car you would have taken me stock. Hahahahahahaha.
Watch out 6/7TT guys, the 4S's are gunning for you all. At least the "stock" 6/7TT's. Hahahahahahahahaha

I wish I had:
-the right space
-the right equipment/ tools
-another car
To do everything like this myself. The DIY SC I am about to do is requiring a lot of pre-planning, and even still, I expect I'll make a trip to myriad shops for parts/ tools. Seems like it'd be so easy with everything at my fingertips!

looks like the first black car will be on the dyno starting wed for finalizing the tune. the other system is being fitted between now and friday. Next we will be looking for a 3.6L 996 manual customer for fitment and possibly a 3.6L 997 customer. Let me know if you have any leads.

Aren't there supercharged cars running around with 7-8 psi now? If that's the case, then why switch to a 5psi turbo? Won't the end result be nearly the same?
What is a safe hp limit on the M96 motor? There has to be some sort of threshold (regardless of boost) where you're really stretching the longevity of these engines. They don't actually have a reputation for being anywhere near as durable as the GT1 blocks....
