Great result.  Just keep away from wet roads.  How many more KW would you expect with E85?

Thanks Richard.
Yeah wet roads are a no-no. It easily spins the wheels in third above 4500rpm in the dry.
With E85 I'll be able to safely run about 26-28psi with more ignition timing, so there is a lot to gain.

Nice figures Rob, bet you're happy with that!  
 
If you get a chance, I'd (and I'm sure a few other people) love to see a video of it taking off :)
 
 

great result Rob, will look forward to seeing it in january at last. the w2a performed well?

I actually just got home from doing the new A2W test tonight.
I'm preparing the plots now, I'll post them shortly.

Tonight the ambient temperature was 23 degrees, exactly the same as when I did the datalogging and testing of my old A2W system last year. So, it was a perfect chance for me to do a direct comparison with my new A2W system.
 
Here are the results with my new A2W intercooler system:

 
Here is the graph from last year with my old A2W intercooler system:

 
I am very pleased with the results, the improvement is even more significant than I expected it to be!
 
- In the old results, there are 3 main boost events at 8, 14 and 32 minutes in the log.
- In the new results, there are 2 main boost events at 22 and 25.5 minutes in the log.
 
- In the old results, the worst-case air temp before the intercooler was 110 degrees C (after a few seconds at 20psi of boost), which was reduced down to 57 degrees C after intercooler.
- In the new results, the worst-case air temp before the intercooler was 125 degrees C (after a few seconds at 24psi of boost), which was reduced down to 41 degrees C after intercooler. This is a great improvement! The pre-intercooler temperature was 15 degrees higher, but the post-intercooler temperature was 16 degrees lower!
 
- In the old results, for the first 6 minutes (and at least another 5 minutes before the log started), I was idling in the garage while mucking around with some unrelated ECU settings, and during this time the A2W coolant temperature heat-soaked from 23 degrees C all the way up to 38 degrees C (due to having the heat exchangers in the engine bay previously), which is terrible.
- In the new setup, the heat exchanger is up the front of the car so the A2W coolant temperature barely moves, and is only about 4 degrees above ambient temperature. In the worst case on full boost, the temperature was only about 8 degrees higher than the steady-state temperature, and it dropped pretty quickly afterwards.
 
- After the first full-boost event in the new results, I was forced to sit there idling almost immediately afterwards, and the second full-boost event was only a few minutes after that.
 
- As forum member 'cogs' clarified last time, the slow decay rate of the temperature sensor readings in some low-throttle cases is a result of the thermal inertia of the sensors, rather than an accurate representation of the temperature. When on boost with heaps of airflow over the sensor, the reading IS accurate though, because the additional airflow causes the sensing element to heat up quickly.
 
The way that both of these tests were done, it obviously doesn't indicate what would happen at the track or driving through twisties in a spirited fashion for minutes at a time, but it certainly shows that the system is perfect for street driving where there is normally plenty of time for the A2W coolant to cool down between high-boost events.
Anyway, if the test was done during more continuous spirited driving, the heat exchanger would be getting more airflow the entire time. I'm confident that the system will still perform well when put under more stress. The temps will probably go higher, but I expect that they will remain totally reasonable.
 

Very nice Rob! Awesome car.

Very happy to see its going in the right direction. Mad power figure. Not sure you will need that in Jan! I would suggest setting the boost at 1 bar for the two days. You will then have plenty of power and less concern of failure.
But every now and then, wind it up and do some fly-by's!
I am impressed with the W2A system. It looks very effective. Look forward to having a look at the package after a run to see how it is managing temps.
Did you fit heat shielding to the wiring/coil packs? 
How were the oil temps, exhaust temps, engine bay after the runs? 

I can't sleep, I keep thinking about my car!
 
I'm so happy with it. I already loved it before, and there were only a few little things that bugged me, but even those little things have been fixed and now I can hardly think of anything that I don't love about the car.
It's surprisingly easy to drive on the street, even with all the power. I was admittedly very nervous when I first drove the car out of MRC on Saturday, but within minutes I felt comfortable like I had never stopped driving it, and then the grin wouldn't leave my face. That was before I had even put my foot to the floor...when that happened I basically felt like I'd entered a time-warp.
 
I don't think I'll ever be able to walk away from the car without turning around for another look.

Yeah I won't need all the power at the event in Jan, I could just turn off the boost control and run the 16psi wastegate spring pressure. That would probably still provide at least 220kW or something like that.
Fly-bys at full boost definitely sounds like a good idea though! Someone will have to get it on video.
 
I've still only got the exhaust manifold heat shield. That alone has made a big difference though, and is totally fine for the street. My right side engine bay vent is completely empty now too, so cool air can easily get in through there.
 
I don't have oil temp or exhaust temp sensors. I've already got an oil cooler anyway.
 
This will never be a track car, it will always be a street car which occasionally sees some track time or drag runs. Therefore I don't need to stress about things that would only ever be an issue during extended periods of time on the track. It will be interesting to see how it goes in Jan though.

It sounds that you have your car exactly how you like it.  Reading through your thread (again) your car has had an amazing transformation.  I can't imagine the amount of hours (not to mention $$$$) of work that has gone into it to get it to where it is today.  
Kudos to you, I'm really looking forward to seeing this monster on the street :D
