Awesome! I got mine here on the shelf ready if anyone's interested in the US!

 

What do these go for?

Finally got my carbon duel intake properly sealed up and back in place.

Looks like my IATs have dropped around 2-3 degrees according to my latest set of back to back logs.

 

Hi,

all nice and good, but you are only measuring in an 8 second time window. In order to see what your new ICs really can do (or not) you need to actually make a true measurement over a longer time: 3rd, 4th and 5th and probably 6th gear as well across the full rev range. Start in 3rd at 2000 rpm and let it go until you reach what you think is still safe speed and you're comfortable with.

In 8 seconds you cannot say anything about the capabilities of ICs.

I once did a test up to mid 6th gear and this is what the data looks like:

IAT start at around 26 C ( I did 2-3 pulls before, so the car was already warmed up). Outside temperature was 19C.

End of 3rd: + 6C = 32 C
End of 4th: +15.5 C = 41.5 C
End of 5th: +17,4 C = 43,4 C
Half way into 6th: +20,5 C = 46,5 C ( 270 km/h +)

As you can see, the IAT stays clear of the 50 C mark and the temperature rise slows down the quicker the car is. Boost was a little over 1.4 bar across the whole rev range (more load than in your logs) and just below 1.5 bar on top.

These are 4.5" Markski ICs. It would be interesting to see what yours do when you push them a little.

Modded from Andreas' post...

I once did a test up to 6th gear (6850 rpm / 315 km/h), and this is what the data looks like:

IAT start at around 26 C (starting from 4th gear/95 km/h, I did few pulls before and had about 80 km driven, so the car was already warmed up). Outside temperature was 16C.

half of 4th: -4C = 22 C (abt 160 km/h)
2/3rds 4th: +5 C = 31 C (abt 185 km/h)
End of 5th: +17 C = 43 C (abt 270 km/h)
End of 6th: +22 C = 48 C (315 km/h)

As you can see, the IAT stays clear of the 50 C mark and the temperature rise slows down the quicker the car is. Actually IAT initially cools down when speed increases. Boost was a little over 1.3 bar across the whole rev range. 997.1 VGTs and those crappy 997.2 GT2 ICs. The whole pull took about 30 seconds.

OTH, I had to use 996 turbo's OEM coolers at airport run last September, and data from those look like this:

OAT +15C, IAT at start 30C while standing at the queue.

End of 3rd: +16C = 46C
End of 4th: +32C = 62C
End of 5th: +41C = 71C
@ 1 mile: +44c = 74C (284 km/h / 6000 rpm)

Boost was initially about 1.2 bar, rising to almost 1.4 bar at top. So clearly wrong (experimental) settings for these coolers (or actually also for these turbos).

 

Next week ill log a full hour at the track

 

you are right...i did a try and bigger is better...

is not interesting for me if it`s wagners or other brand...but this mod is very noticeable

intercoolers must flow.... (not only the temperatur give you the poweroutput)

 

Cheers bro only straight up honesty coming from down under.

Very pleased you were impressed as I was with the coolers

 

oh yes very good decision...

 

Fitting the dual intake carbon air box which is now fully sealed has resulted in a need for 10% more fuel by 7000rpm, thanks Todd K at Protomotive for his continued excellent service and advise.

Modified Dual Outlet Airbox is next.
