11:1 Engine Rebuild

This is just a question maybe a little off topic
Why would you want to increase the compressions ratio? Isn't 10:1 high already? Cause most turbo cars have low compression ratio

Most turbo cars have low compression because after adding in the forced induction the compression is substantially higher

If you run Naturally Aspirated higher compression results in improved performance and an immediate kick as soon as you touch the throttle, no delay while the turbo spools up.

Depending on who you talk to, 10:1 and 11:1 is not considered High compression. I'm not talking about race cars or special applications here, either. When you add in the dynamic compression of any supercharged car, you can easily break 15:1.

Cam,
I am using a NA EG33 in a project and just starting on the engine here in Tacoma. Would like to get in contact to get more info and advise on your build. PM me if you are interested. Your inbox is full.
Thanks

Let me guess, you're putting a EG33 in a Corvair?

Bill,
You're right. How'd you guess?lol
It's mated up to a 5 sp TA(not Subaru) and mid mounted. Have pretty much finished the rear suspension/engine cage and now need to tune up the engine. Looking for 225whp NA. Any suggestions?

I am cleaning out my inbox as we speak. What are your ideas for engine management? I am willing to help in anyway I can. I could even come down and meet up with you for some face to face time, since I am interested in seeing your project. A corvair huh? Sounds pretty sweet.

Go ahead and PM me and let me know of any questions or guidance you have/need.
