Rotary Engine Failure due to Side Rotor/Side Rotor Housing Clearance..

Glen,

So, why is it that you now want to discuss this when earlier today you didn't??

When I first asked, I wasn't asking you to provide with exact number that you are shaving.. i was mearly asking what you meant by increasing the clearance of the rotor as I wasn't sure what you meant by that..

Regarding to your professional disagreement with my builder..., I'm a firm believe of 30+ years of experience and his ability to do many things at the same time hiding from general population. For years, he did not want to build anyone's engine and asked me not to give out his number. Its just recently he decided to build engines as his children are older and now wanting to get back to rotary. He also pointed out to me things that I never noticed before during my research and his explaination made sense vs. no explanation or BS reasons people like to feed.

Regarding his detail reasoning why he doesn't think its necessary for street driven car is I guess same reason or similar reason as why you would shave it in the first place. Also, if you truly believe its necessary then why wouldn't mazda do it in the first place..

I have a process of clearencing that is ours ...the basic idea has been know for years and years .

Mazda does do it....If you buy rotors brand new from mazda they have a clearence. It is better to increase it ...I stated that before. You were asking me to give you details on what we do this is not for the public this is some of the things that gives us our edge.

If you read what I said phill....you would have seen clearly that I stated we increase the clearence that was already there from mazda do to increasing horse power.....

Also. let me be clear Mazda clearenced these for a certain output of a 1.3l engine some from 100 to 255 and yes the rotor "clearence" increase as the output does from the factory, Phill......

What people need to remeber we are taking this 13b were it was never ment to go.... 1.3l puting out 500hp ...250hp per rotor (no its not that exact)....

So I believe if you are building an engine for higher hourse power you need to compesate for the increase in power.

Phill, I dont know who your builder is but I have to say I know hacks that have been doing this for 40years and I know poeple that are ungodly good that have been doing it for a short amount of time so 30years does not mean much to me. When some one says not to do it in street cars are they saying stock .... This is why i disagree with this guy becuase from what you said he said it is not good for the street and you have to be careful doing.....This is just not true, you can go to far with the clearencing but if you have it done by someone that knows what they are doing it is not an issue at all to have it and can not be bad no side eefects like in porting something to big and a side seal could drop etc.

Look I believe that clearencing is something that everyone should do increasing horse power I have seen the effects of not having it in high horse power applications some survie some dont and I am in the business of all staying alive my company and reputation demand it

Ok ....so Phil so far nothing I have said give my process away from they way you cam across you wanted me to give specific details to what we do I am not going to do that. I am in business to be the best and I am going to keep it in our bag of tricks that make us one of the top builders.

LOL! Glen, if you go back and read what I asked, I was asking what clearance you were talking about as it was very general statement. I think it could of been simpler if you would of been bit more specific to what clearance instead of sayind its proprietary.

It wasn't until I posted what Racing beat consider clearance and their recommendation is when you became more involved in explanation..
