Well, in my opinion dual twins are too much bimmer look.
Edit. Hmm, ~50km to the nearest E85 fuel station. What size injectors would be enough to max out the HX40S with E85?Last edited by Thuppu; 7 June 2012, 13:24.

Well, it's very theoretically but let's have a go.
- 700hp capable turbo, that's at least 0,6kg/s airflow.
- Burning air to fuel at a ratio of 10 with E85 mixture with density of 780kg/m³ would need around 4500cc's per minute, divided over 5 cylinders is 900cc/min injector MINIMUM.
- Max mapping DC of 80% to have enrichment margin, make it 1200cc/min flow.
Of course a smaller injector could do combined with increased pressure delta over in injector by tweaking the FPR.

Exhaust still not finished but drove it today. My neighbours propably love mee.
Looks quite sharp in the image, but there is much rusty and rotten places on this car. I sure you that better ones has been broken to parts many times.
