For daily drivers of course a 997TT could be far enough with its stock IC's, a VW golf too...

But it is not my need, my need is Big Power!

Sacrifice under 3000rpm because of Ic's? Because the worth 997.2Ic's flowing?
Let me laugh...

Stay stock and me tuned!

I will retune after the mount of the 997.2 Ic's, to benefit the best those coolers will allow.

 

^^^^997.2 IC?
If "BIG POWER" is what you want, wouldn't Karim's data support going with TPC/Protomotive?

 

I did four runs from 50 to 250 km with ,2 ICs and IAT never exceeded 47-48C...OEM 997,1ICs had 65 at first run,70 at second and 73 at third...Big fat amICs had 68 at first and 76 at second...I wonder if any tuner would dare to retune DME with amICs...
On the other hand there are two things crossing my mind...
1)It is really dissapointing that APR does not provide a retune for any upgrade done to the car...I believe my car is not in position to take full advantage of lower IATs...
2)Sometimes I wonder if the specific sets of amICs were ok...of course I pressure tested them prior installation,but simply cant believe they perfrormed worse than OEM...

 

^ Depends on how much you want to spend! To further stir the pot, here's the 5" Protos on an "800hp" car vs 3.5" CTRs on a 660hp car, both cars running 1.5-1.6 bar of boost, both to 300kph and both within 1C ambient. The 660hp car gets there (100-195mph, both WOT) 0.5s quicker. Bigger isn't always better, but both clobber stock .1s!

Proto 5"




CTR 3.5"

 

Earl,what does CTR stands for?

 

UK motorsport company that uses HS Marston Aerospace cores. Very similar to Secan but around half the price (somewhere around 10k USD!).

 

WHAT A DRAMA!!!

 

Intercoolers, serious business!

 

Yeah CTR and Secan r the best!!

That IAT log took from that 997 gt2 r??

Hi Can, My tune was sold with the upgraded turbos and ICs so I can only assume it was optimized to those specific hardware components. Not sure if a retune for an IC would produce any significant HP improvements.
What a quagmire. Do you know what turbos were on the two different cars?

 

No problem skand i can wait for your vbox times....just hoping for a prelude to those with a/your Butt dyno review first. Karim was able to give one but you seem a little shy of providing one. Possible to enlighten us of you impressions?? You have some impressions you can impart for us curious souls? Next week is a long time comming .

It would appear its become far more "game on"!! than "game over"!!. Maybe an edit on the name of this thread is warranted .

 

I think "best" is not so difficult to define with regards to ICs. It's acquiring good data to prove which one is actually the best is the problem.

 

So in a way it could well be game over for the thread in its current form....and not necessarily game over for all of the different IC offerings. It would appear at this stage the solution for Karims car not the same solution for Skands car even though his IAT's were able to be measured. Thats where the butt dyno may prove to be the ultimate and more reliable judge. Another reason why i would love to hear skands butt dyno impressions at this stage. Not to jump the gun on his times, but more so to get a user gut feel from being in the drivers seat between the back to back testing of the IC's. There would have to be an impression of sorts worthy of mention..

 

Ahh...missed this point earlier so, what different exhausts did you try so far? I know you have the remus but what are the others? What are your impressions so far with the exhausts? Did any add or subtract any performance?

You have certainly gone all out here skand in a bid to squeeze that little bit extra performance from your car and APR so i applaud your efforts doing all that and sharing this info even though there has been some close scrutiny which has all gone toward making this a rather interesting thread so far. I honestly hope you get something for all your time, money and efforts but eitherway it doesn't matter if you wound up going a little backwards if the APR tune did not respond as you hoped. What we would really like to hear is a full scoop review and not just simply about the IC Iat data which may or may not amount to performance gains or, better times in Vbox tests when your tyres are eventually sorted. As you saw Karim gave a fairly comprehensive and unashamed explanation to cover his testing so that is all what i was hoping to hear from you by now.....a first hand user impression of the things you have experienced during your testing being in the drivers seat.....good bad or otherwise it doesn't matter.

 

Parts arrived today, "made in Portugal" sticked on!
I will mount and test Asap.

(weather "ultra" rainy in France)

Cheers
