Seems a bit silly to spend all the extra man hours and money on a turbo setup to only run 1/2 bar or around 7.5psi. Granted your spool times are extremely solid, I just feel like there is way more on the table.
Also shy away from high quality fuels on "eco" engines. I don't want to buy a car for 20-22k(USD) and have to fill up at the pump with premium fuel, that doesn't make sense to me.
You might also save yourself some material costs and weight by using an Air-Air inter cooler on some of the smaller engines. The performance difference will be negligible. I find the Water-Air is really only needed when you start to really up the boost levels say 1.2 Bar and above (20ish psi+).
Keep tinkering friend, I know you can make them better.
On a side note the economy figures are outstanding, but the man hours are way to high for high volume engines, and watch your costs as well.
I challenge you to make an engine with 40 or less man hours, costs below $2500 and economy around 35% that still makes good power. Its possible just takes some time. Ill give it a go later when I get home from work.
