The 510 Realm

If 61 degrees should give a cranking compression of 215, and knowing that increasing the closing degree lowers the compression, I assumed that maybe you are advanced one tooth (or 9 degrees). I was hoping that 70 degrees would drop it to 160psi and that would prove to be your problem.... Oh well.

What about retarding the cam a tooth and trying it? Cheap and easy to do. If it improves, maybe try another tooth until power drops off. Then fine tune it closer by advancing/retarding one 4 degree hole on the sprocket. Each hole is almost 1/2 a sprocket tooth.

You expect 160hp? So you are down about 50%... nothing to loose by trying.

Well....all back to good. The timing mark plate was knocked and what I assumed was TDC was not, straightened that out, then changed the cam timing. Now 215 compression on all cylinders.

Woot!

glad to hear you got it sorted out. can't wait to hear new dyno numbers.

Good to hear it was something simple. It would be good to see and hear some footage of it at full song next time its on the Dyno or at a race track.

Glad to hear you had an easy fix. I love those - especially when you can find them (and haven't already spent a bunch of effort chasing down the wrong stuff.)

I did really, but it was multi faceted problem as it turned out. My distributor needed to be recurved for the new motor too, which added to the confusion.

So when are you going to re Dyno your car so we can really know what that L16 puts down?

That is impressive to make that call over the internet. You are the "L" master zen.

This week...if my "ship comes in". I blew $190 last week on figuring the problem.

time for predictions...

I say 165HP

I'm guessing 148 WHP

Alright, I should be more specific. 165BHP, at the 'brake', on an engine dyno, calibrated to S.T.P. conditions, operated by a credible and knowledgeable person, all overseen by at least three dependable and reliable witnesses, with one witness tasked with fair and frequent distribution of ice cold beers...

I thought you were going to say it had to be on a Rebello dyno haha

I'm going to say 145.
