Cannga- Sorry, I am asking Mike of AWE a question.
Mike- I just received a Ruf RTurbo with Porsche Motorsports GT2 intercoolers replacing the orginal ones from Ruf. This is a 996 variant, Ruf VIN, do you know anything about these intercoolers? The car has the "Nardo" 590bhp engine
Thanks in advance - Gerry
I don't, and I doubt they are anything special. Probably just the off the shelf intercoolers used on a 996 GT2 or X50 equipped 996TT. We used to use those, too...

1. Are there protective benefits to other components of the turbo system when you lower Intake Air Temp? That is, does lower IAT affect THAT MUCH the operating temp of the turbo's components, like that VGT?
Or is the benefit of a better intercooler mainly an increase in power from cool, dense air?

There is a definite relationship between IATs and EGTs, though it is not linear. For example, on a 997TT with our 750R kit, with an increase in IATs of 15 deg F, timing dropped 2.25 degrees and EGTs went up 23 degrees.

A properly designed intercooler will have little loss in pressure when exiting the intercooler.
Go too big and the air has to fill this massive cavity. That will then slow things up when it comes out the other end. This then will equal less power.
So there is no real "acceptable" drop. The goal is to just make sure it is as little as possible without actually causing a restriction.
It's a fine line, but with experience and proper testing we feel these are the perfect balance.

Let me clarify what I wrote. I am not an engineer, so I apologize. I was corrected.
The volume of intercooler does not equal pressure restriction. It's actually a combo of charge row sizing, number of fins inside the rows, and end tank design. For example, our FMIC we offer for the B7 and B8 Audi A4 2.0T is huge, but has a very low pressure drop.

Thank you for taking the time from your busy schedule to explain. I really appreciate it.
I believe one time I asked you (or maybe another pro) and was told that YES, when you upgrade the intercooler you should upgrade the ECU software to take full advantage.
But looking at the data presented so far, it seems to me the advantages of the better A.W.E. intercooler are there even if you don't plan to upgrade the ECU software, correct?
I think the answer will be relevant to someone like me, who has MORE than enough power with my GIAC stage 2 , or perhaps someone with another brand of ECU mod, that does not have specific intercooler software upgrade?
Congrats, as always, on the great work. It's really a good thing that I don't live close to your shop -- I could see myself hanging out at the A.W.E. shop all the time. Easily.

And don't forget the helpful and friendly pre-sale and post-sale service and support! AWE products are cutting edge - but they are also very people oriented.

That is correct. The stock IC's are cheap for Porsche to make in mass quantities. They are decent, but not as good as something that can be found in the aftermarket. Just like many other parts on these cars. Remember, Porsche is a business and the bottom line will always rule.
If you do have aftermarket software, regardless of brand, ask your tuner if they have IC specific software. This can't hurt.
A turbo car will always love cool temps and higher octane gas. Heat is your enemy. If she is inhaling the coolest possible air, she will perform at peak levels even when giver her a proper beating...
Can, if you are ever on the East Coast, I urge you to stop by. I enjoy giving tours and there are 25 guys here that would also like to meet an out of town guest....

I have to admit...on my way to work this morning while it was cool my car was a monster...on the way home it was hot as heck and it wasn't the same...
I can't believe I'm even thinking about intercoolers...I need to log off...

One of our core philosophies is full disclosure. By showing how we test and what are findings are, it now raises the bar. Meaning our competitors will now have to do the same in order to compete. This is a good way to expose those that are just parts resellers rather then actual tuning houses.
We have a staff of 25 with the majority working in Engineering and Manufacturing. These guys work tirelessly to design and make parts that actually work as claimed! Unfortunately this industry is littered with the opposite.

with my GIAC stage 2 , or perhaps someone with another brand of ECU mod, that does not have specific intercooler software upgrade?
Easily.
