i sent you a PM with my email. shoot my an email and we can talk. it looks like i have a buyer that may be taking them off my hands today.

 

I can probably help get them to Jonkoping for you. I work for Saab Training Systems US office and can have them sent with other equipment for you. Let me know if you need help.

 

I have a 997tt tip 2007 ,it has a softronic tune and agency power ehaust 200 cells.The car is fast starting from low spped to ~120mph but beyond that ,you can feel that the acceleration decreases dramaticaly,i logged the car and realised that at this stage its pulling a lot of timing and the intake temperature is very high,about 150 to 160 fahrenheit,Do you think it is pulling timing because of the high IAT ?if this is the reason ,the 997.2 intercooler can solve this problem?I appreciate all helps

 

Yes it's pulling timing and dumping fuel, i was having the same issue too. I was reaching 150+ fahrenheit with my stock intercoolers. I installed the new larger units and my IAT dropped to 107deg on the top end now. 150 reading were in the summer though. But it did make a huge improvment. All of this at 1.3 bar.

 

yes its also dumping fuel,normally lambda is about 0.8 but when IAT increase ,the lambda drop to 0.68 which is very rich.

 

get your car pressure tested to 25 psi and then log it .. something does not sound right...

 

Mark,the car hold perfectly the boost,i logged it ,it has solid 1.35 bar from 4000rpm to the redline.what do you think?

 

That doesn't mean you don't have boost leaks or bad check valves. you can log requested lambda to see what it's asking for as well.
With mods like yours you should be doing boost leaks every few months.

 

Mark,do you know,i am not refering to my P800 GT2,i am talking about a 997tt flashed by softronic!

 

Also on my switzer p800 i never had any boost leak since one year and a half,switzer are very consistent and reliable

 

I have the 997.2 radiators and can only say they work great!
It's not that I have 20 more HP, but my lap times are keeping steady during the race and the car pull strongly.
Definitely a good modification, thiugh to cut a long story short I also changed the upper and lower air funnels, plus modified the lower ones to adapt to the GT2 997 rear bumper.
The GT2 RS has a different shape near the lower air funnel.
Saw today on Porsche Scene Live the 850 HP GT2 by Sportec.... Amazing, + they made a special built in funneling to estract more air.
Sportec is from suisse.

 

Got to ask, read the whole thread but still curious are these intercoolers truly only meant for track guys to avoid heat cycles or would the regular street driver with a stage 2 flash and an aftermarket exhaust achieve any true performance difference over the stock 996tt coolers?
Is it worth pulling the trigger, or should I just wait and see if I ever buy some 16g or billets? Not sure if I will yet as needing a new clutch has always held me back.

 

One way to determine any kind of performance improvement after installing a mod is to measure the volumetric efficiency before and after the mod. It's pretty straightforward and will give you a fairly accurate assessment. So you would need to do this with the stock intercooler and then with the aftermarket ones. This is what I would do.

 

True enough, was hoping someone who has done this mod can vouche for any performance gains over stock in a daily driver type situation like they do with exhausts, intakes, flashes etc. don't track the car but always interested in a mod that will make a noticeable difference in everyday driving. Anybody?

 

Yeah someone who is in tune with their car can probably just feel the difference, like MBailey. His tush is quite sensitive. I'm always amazed when he tweaks his mods, he can feel the difference and when he sends me the data, it indeed corresponds to the change in his VE.
