Hi All

Im Ross from AVO japan Paul is still on the road on the way back from 86fest

I said on the Facebook MAP Sensor not MAF Sensor. The stock MAP sensor (Manifold Pressure Sensor) Stops reading at 5psi (.35 Bar) this is no problem for the people who will run up to 5 PSI boost, over this the load deflection dose not calculate correctly. We will be testing a higher pressure MAP sensor (Manifold Pressure Sensor) soon.

Regarding the Oil Temp I have done over 500km at the track in NA form over this summer session the last time it was 38c we had a 5 Lap sprit race the water and oil temp did not get over 100c in the race it spiked a bit as it come back in the pits but all cars will after being thrashed for 5 Laps. What we seen in the past with our Time attack Race Car and the D1 86 Drift car we built is after 7000 RPM the Water pump gets cavitation this cavitation air causes the exhaust head to get hot this will increase the water and oil temp and cause detonation. This is Why we never up the RPM limit on Subaru even our Race Car we try for peak toque always. With the Turbo Fitted we will keep a close eye on the water and oil temp and let you know what we find. I hope to be testing at the track on the 16th off this month.

The next step this week for the AVO BRZ will be Fuel System testing to see how reliable the fuel system is for the 5 PSI boost.

We will test the fuel pump flow in the car and put a external scope to test the injector duty cycle on the direct and port Injectors. There is just not enough information on the logging to get the full information we are after.

The turbo kit production run has started at the factory so please give Paul a few days to get back on his feet after the 2600 mile drive and he will have more information for you on this

Thanks for your support

Regards Ross Wilson
