I perused your website and would have questions, based on my own research. Questions like:
1. How do you achieve 4000 psi with an ordinary EFI fuel pump?
2. How do you control the temperature in the exhaust heating unit to maintain 600°F?
3. Have you tried heating the fuel past 900°F? My experiments got 'interesting' in that range.
4. Have you run into issues of maintaing exhaust temperatures when idling?
5. What are you using to control the air:fuel ratio? I've found that controling the fuel ratio of heated fuel can be tricky, because gasoline is a mixture of over 4000 constituents that vary in percentage, each with its own vaporizing and thermodynamic characteristics.
