Another big milestone tonight! Fired up the motor and boy is she sweet!
This I am sure is due in no small way to the long suffering Jac Mac who has been plagued by long emails and late night phone calls. Over the last few years he has attempted to educate me and keep me on the straight and narrow, and save me from my own follies and foolish decisions. Not always successfully, in his view!
And equally to Lim who has been there to do much intricate machining on the motor and most of the bits hung on it, not to mention the cast dry sump he made.
So I owe both these guys a huge vote of thanks:chug:
Start up tonight was performed by myself, Lim and Leon. Heated up the oil tank, cranked it over to get up the oil pressure, then ignition and fuel pump on, four pumps on the throttle and hit the starter. It fired up in less than two seconds instantly on all eight and we brought it up to 2500 rpm, adjusted the oil pressure to 50psi, checked the timing and ran it for the next 20 minutes checking for oil, water, fuel leaks. Nothing! All good.
Since I have opted not to run fans, after 20mins the temperature was as high as I was comfortable with, so reset the timing at some higher revs and called it a night.
There was really only one issue and that was every time we brought the revs up to 4000 the rev counter died. The reading returned to normal when we dropped the revs. If the motor was blipped harder the tacho crapped out at about 3500. Any one got any ideas where to start looking to cure this problem? Ignition is magnetic distributor and MSD 6AL. Tacho is Smiths motorsport 'classic'. I Will post a query in the relevant technical forum.
Next milestone is track testing in a weeks time. Weather permitting! Still heaps to do before that!
