Hey Phil, I'm happy to see the work you're doing here and that you're sharing it with everyone, thank you for that. I've followed your race program for a long time as a Subaru owner and its great to see you with a new project here with the FR-S.
I wanted to let you know that we do have some great injector upgrades available for the FR-S and BR-Z. If your development takes you this way I'd love to help you out with an injector solution to fit your setup. We have the following sizes available:
660cc
770cc
1100cc
2150cc
We also have a 900cc option available IF it is possible to space the fuel rail up slightly to accomodate the extra height of this injector. This is a perfectly normal solution and something commonly done on other applications, but it will come down to whether or not you have the physical height to move the rail up slightly without any obstructions.
The 1100cc injector listed above has the same extended tip as the stock injector, whereas the others I listed have a normal short tip. Either setup will be fine for this car as we have not found any discernible differences in real world results for fuel economy or performance going between the two tip styles.
Also arghx7... thanks for posting the info about port and direct injected E85 octane and temperature differences... it is really interesting to see the data comparison there.
I'm going to subscribe to this thread to follow along with the progress here and of course if anyone has any questions just let me know and I'll try to help out.
