Some that wish to read into that assume that meant I would manipulate a valve job... that's not the case, just you hearing what you want to hear. It was a reply to a question specifically about valve job specifications.
As referenced just beforehand, a rule set like spec Miata actually has several pages about engine internal specifics, like posted below.
I did not say ''I have not seen limitations'' because I have exploited them, I said that because there are no posted values of limitations...

Short of buying new cylinder heads for every rebuild, there are modifications that need to be completed on any regular standard engine build. This is supposed to be cost controlled spec racing and engine rebuilding is part of it. There should be rules with values about plunge cutting and valve jobs and decking heads like any other reasonable spec but BSR is not at that level of precision, yet.

People will believe what they want... even with several independent dyno runs at several tracks back to back against other cars right out of qualifying. We know what the cars are running HP wise across the field because they have ramped up dyno testing and that is a big step forward.

Eric,

Never thought otherwise -- basically having a beer discussion over the net :-)

I'm building a pair of SP-1s, so arguably my question is mute to me. However I do track a Boxster S and I have either rebuilt or been a part of about a dozen rebuilds of these engines and I was trying to envision how the HPs could vary.

Note I'm a EE and shade tree mechanic hack not a professional engine builder -- so this is more of a thought exercise for me.

Mike
