OK...so if I might just jump back on topic here. For those interested, here are a few pictures of the billet end tanks before assembly.

 

Really beautifull End Tanks Tom, the core seems fine too, those parts might perform!

 

Very nice indeed. The IC arena is such a gray area that if someone actually produced test results that connected with the consumer, they could do well. So far, there is mostly anecdotal data here and there, not much to go on when making purchasing decisions on aftermarket ICs. It would be nice if some company sets some standards for measurement, i.e. thermal efficiency and max flow rate at say 1 psi pressure drop.

 

here's a comparo to "another tuners" ic
green CMS
red "other tuner"
This dyno says it all!!!

 

The CMS coolers look like they should work but so do most other AM coolers. The real test would be how they perform up against the .2ttrs coolers don't you think? Thats where the current focus is at the moment....and rightfully so given the most recent tests from Skandalis. Comparing an un named AM manufacturer against CMS is pointless really. And why the lack of transparency anyway with not naming the Brand of the contesting IC? That just further goes toward making what coud only be seen as a very shallow argument. The benchmark is very clear....and that is the OEM's best offering. Now if an AM IC manufacturer/vendor hasnt provided data to prove they've actually beaten the benchmark then why bother even comparing against another brand anyway.....whether named or anonymous. The gauntlet has been thrown down by the new .2ttrs cooler.....but we get silence. Pretending its not there is silly.....especially when the benchmark is 2500 cheaper.

 

Why would your power take a sudden drop at 5250 then steadily increase beyond that? At higher rpm, you're certainly not creatling lower IATs or better flow. It doesn't make any sense to me.

 

i just read the last pages of this thread...
1)Champions new ICs look like jewelery...Great work guys...
2)I really dont try to convinse anyone to buy GT2RS ICs (same as 997,2TT)
I just installed them and took a log...thats all...i saw great differences and reported them...
3)In the future I will but a second ECU so to make my own custom tune...I wouldnt like to overwrite APRs very expensive tune...By that way I will try to take full advantage of the lower IATs my car has now...So far the car is running very constant at repeated pulls and IAT stays well under 50c in comparison to 70c with OEM ICs (997,1tt)
Bad thing is that APr did not even answer to my mails for a reflash to take full advantage of new ICs...Manager of APR Greece did his best but headquarters did not bother to answer...

 

Me neither TT. It could be two different tunes, different exhausts, turbos and so on....who knows?? But it doesn't add up why the curve recovered after the drop at 5200. Maybe more than just ics in play here. To make a real comparison on IC performance all the variables need to be equal.

Well Skand if the logs show your new .2tt ics are working better than what you had plus all the other AM coolers you tried then it was a worthy excercise and, worth the spend. Funny thing is your proof has since resulted in a number of 6 speeders to buy these .2tt coolers. Ive been holding back for some proof to the contrary but by now its becoming obvious there is no point waiting around for miracles. And for 2500 extra there would need to be some miracles.

 

Not sure why, but this was happening on every run...the only different variable from my car to any other car with 68mm turbos build was ICs so this was the outcome when CMS went to theirs

 

Tom (champion),
I just read your comment about my log results (on page 3 of this thread,post #35...) and you think possible that I did round off boost figures to show better esults for 997,2ICs...Have in mind my friend that I dont have anything to hide because i do not sell ICs...You do so...not me...I ve turned my 110000Euro car into an IC project car and have tested 4 different types of ICs,in real road conditions...i would have tested yours as well (before i bought 997,2TT ICs)If you had given me a payback garantee for worse results than 997,1TT ICs...But you didnt...I am not willing to public our emails here,i am just an Engineer with several degrees who loves automotive tuning...So please recall your statement regarding "strange" results.
P.S. Do your homework and learn how durametric operates during logs and how results are shown...
P.S.2 understand that 997,2TT and GT2RS ICs are the same...same part number...same...So realise these ICs are designed to operate at high boost...for GT2RS and not only for low boost for 997,2TT engine...

 

It's one thing collecting data but it's another to interpret it. I'm not convinced at all from this data, that one can conclude the other AM IC is inferior. I think the better conclusion is that something very odd happened at 5200 that was systemic in the runs as opposed to an inferior IC. This result does not rule out the fact that they both can be excellent ICs.

 

The two dyno plots that Arone997TT posted were from his car, done last Friday, both within 1 hour of each other. The ONLY constant that was changed were his intercoolers. If you look closely at the graph, you can see that while hp may recover slightly, torque does not. I will have to talk to Louis to get a better understanding of why this happened, but I can tell you that NOTHING else on the car was changed. Same tune, same weather, same turbos, same everything....just different intercoolers, within 1 hour of each other.

I promise you, there is not trickery here....just some results.

skand...I was not implying anything about your post. We do our datalogging with the GIAC datalogger, not Durametric, so I'm not familiar with what you see on it. The GIAC logger shows boost figures to the 1000th digit, so that's why I thought yours was strange. I wasn't trying to question your results...just making an observation. Sorry if it came across that way.

 

What mods are on your car? ie turbos, ect?

 

Not sure, Tom what mods do I have

 

timing coming out to quell detonation and then being fed back in would be my guess. people really need to start posting logs with dynos...
