Sneak peak of my new coolers!
Discussion
Here's some result I have lots of logs but I though I would just post the result's that mean something.
Test has been done on the same day within the space of 5hrs
Stock coolers.
Engine speed/ Intake Temp/Ambient temp/Vehicle speed
6226.5 / 44c / 11.3c / 237.4kmh
Aerospace coolers.
Engine speed/ Intake Temp/Ambient temp/Vehicle speed
6377.5 / 29c / 13.5c / 237.4kmh
6476.5 / 37c / 14.3c / 300.24kmh

Here is logs of before and after of the stock core vs aerospace core.

My eyesight is not so good but those comparative logs do not look very comparative !Stock

The before logs (stock cooler) are reving out in 4th gear then changing at 6XXXrpm into 5th whereas your new intercooler logs start in 5th at lower revs from the begining ?
If the above is right then the comparison is flawed since the stock coolers have to deal with much more heat from the rev out in 4th ?
Having said that they undoubtedly look better than stock but are they better than GT2RS at these sorts of low boost/power levels ? These are the cheaper Marston cores as used by the UK GTR tuning guys right ?

I'll be honest I'm not sure what gears the logs show or what gear I was in for those log's I have posted, I was kind of excited that there was a big difference and wanted to share.;)The before logs (stock cooler) are reving out in 4th gear then changing at 6XXXrpm into 5th whereas your new intercooler logs start in 5th at lower revs from the begining ?

What I do know is I just took a snip out of the logs I have and used the vehicle speed as a reference to try and get similar comparison.
As far as testing them, there is more to do so there will be plenty more logs coming in the near future.
These are not the cheaper marston cores that the GTR boys use they are the highest spec martson do.
Even higher spec marston cores than what CTR used in theirs from what I have been told.
Either way I am glad you have commented as I know you are a bit of a Guru when it comes to this topic.;)
Nick,
If you are going to present data logs it is important to compare like for like. You did the tests same day, similar ambient temps, this is good. The wrong gear issue is a big one and renders the comparison pretty void as the stock coolers would have had much hotter IATs coming through at the 206kph mark courtesy of the turbos spinning at their maximum revs in 4th gear so the data is wrong for comparison purposes.
I would say you also need to include throttle position and boost in the data to give a good picture of what is happening.
I understand you were just excited and wanted to share your new toys, I've had that feeling
Re your cores, I think they are made by the (Marston) people who made them for 9M when he had a stab at making some 993 turbo intercoolers, a good product but from what I understand a different manufacturer to the guys who made mine ?
I understand there are two producers within HS Marston, the Heat Transfer division who I think made yours and the Motorsport division who made mine. I presume these divisions work out of different locations ?

I just went through the entire logs to find something suitable.
Stock core
Aerospace core

That makes my brain hurt Nick, can you give us a snapshot like you did on Wednesday?
Both logs from same gear.Stock coolers.
Engine speed/ Intake Temp/Ambient temp/Vehicle speed
6226.5 / 44c / 11.3c / 237kmh
Aerospace coolers.
Engine speed/ Intake Temp/Ambient temp/Vehicle speed
6371 / 31c / 13.5c / 237kmh
Well What can I say, for the best part of 17 days I have been driving my car a hell of alot more than usual to test these intercoolers properly and it takes no genius to figure these are amazing coolers.
The difference it's made to the performance I could would be similar to removing the stock exhaust and putting a catless system in place, YES it feels like that much difference!!
There is never any holding back on power and bear in mind that I haven't even re tuned the ECU to see if there is any room for more gains!
When you put your foot down in any gear the torque just rushes and holds out till alot later than before and also when you are in heat soak situations ie. stop go traffic or high speed runs, cross country runs the coolers seem to reject most of the heat and I have never felt my car hold back power since they have been fitted.
They do also change the sound of the car as you can hear the turbo's spool alot better and the car seems to breathe easier as if it was being strangled before.
I cant wait to test them when the weather is warmer and on track!

I don't wish to be a party pooper but don't forget that the very cold air at the moment will be contributing.
I have taken that into consideration! If you read all of what I said then you wouldn't say what you just have Mr pooper!
