I did I'm still trying to put a whole write pic deal together.

They're a little more obtainable dollar wise from the S.A.E. site. I think you've been able to prove some varying differences with some significance through your adaptations. Just my own opinion based on my experience, I'd keep your compression where you had it (didn't see if that changed or not) related to pumping losses and the VE that takes place bringing up AP through your compressor. For your lean Cruise it's imperative your engines reciprocating parts meet with least resistance.
Keep in mind the engines overall inefficiencies due to it's design. I realize you do via the technical changes you've made thus far. It's all about incorporating/bringing up efficiencies at any point within the entire system. Good job amigo!!!
btw does your turbine have a split inlet?

I have a copy of "
Internal Combustion Engine Fundamentals" by John Heywood. I use it as a guide, but I wish there were more on lean burn engines. So I might have to get his SAE papers also.
Your right I have done something different then what the status quo is by running a lower compression engine. I have to thank you for the final help on my project by advising me that the turbo is producing more heat and pressure at cruise speed and how it will help with the fuel itself. This is a must needed part of the equation when running a low compression engine.
The turbo is a single T3 undivided turbine inlet. I might have made a big mistake by going to a larger frame turbo. I had a friend do some testing with the same engine with this turbo and the results were good. My reasons for messing with a perfectly good combination is I want to make over 450whp while being able to drive down the road with no hypermiling skills and get over 80MPG and have a driving range of 800 miles. This turbo will get me the performance I need to walk away from any stock ZO1 Corvette or Tesla with a long range ability. I cant help it. Its the performance side of me
I get tired of people saying you can't have performance and fuel mileage in one package. You must take one road or the other. Thats BS you just need to make your own road.
