Re: 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.

Re: 11:1 Engine Rebuild

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.

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

Re: 11:1 Engine Rebuild

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?
Mike

Re: 11:1 Engine Rebuild

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.

Re: 11:1 Engine Rebuild

Cam,
I have PM'd you a couple of times but not had a reply. Am hoping to order forged pistons next week and would appreciate your input and experience.
Am here in Tacoma.

Mike,

Hydro engine management, INT/EX cams, tuned exhaust manifolds, minor port and polish of heads, larger injectors.
