Rolling Road Session
Posted: Sat Jul 06, 2013 10:31 pm
Finally got the Stylus back on the road this year (it’s a long story), and took it to BD Engineering at Newington for a rolling road session, along with my brother in law’s Alpine.
Would thoroughly recommend Andy at BD Engineering, initial BHP was 111, after a lot of head scratching it turned out the Xflow was not producing the compression expected and the timing was well advanced (20 degrees, verses 10 degrees norm). Looks the timing was advanced to maximise engine output from the lower compression, although the engine bores etc looked OK. After some more tweaks and the mixtures properly setting up, tappets adjusted etc, output rose to 113 BHP, with the engine feeling far more tractable.
Just got to decided what to do next – keep as is, or engine out for further investigation over the winter.
