Basically, I doubt that this much power was made rich of 12:1 and it was probably closer to 12.5:1. This is not a terrible idea, but it is a bit risky.

Please don't let Ted get to you, he is very blunt, but he has a lot of experience and it certainly is not to be discounted. The question that he asked was valid, he just asked it in an aggravating way.

It would seem that you have an excellent-condition stock turbo to hold 9 psi to 7500 rpm on a ported engine. What are you running for exhaust? How aggressive is the port work?
Is the porting a trade secret, or can you provide pictures?
I didnt come here to argue with TED or anybody else, I came here to relax and share some real world results. shit that has been tested and proven. wether is 700+rwhp or in this case 280rwhp. to answer your question, 12 to1 or 12.5 to 1 is way to lean on a turbo charged rotary engine. you could do it but it's asking for trouble.. in this set-up. car dynoed the hp @ 11.2 to 1 air fuel ratio. this site is a piece of shit.. so if ur looking to carry on with questions. nopistons.com is my home. i also have this thread over there..

Since you offered the invitation...

You still have to unnecessarily swear and insult others?
If you are going to insist on your poor attitude and can't objectively post without keeping your attitude against me (and others you don't like) out of it, I would rather have you leave and stick with other places who can swallow your negative side.

I would normally take out all the unnecessary bits and pieces, but you'd just give me crap for that.
I'll leave the last few replies just so others understand what's going on.

I'll take all criticism in PM's.
This thread is done for.


-Ted
