GIXXERUK Posted March 6, 2014 Posted March 6, 2014 Have you tried emailing or pm opie oils ? They can probably help Quote
Richf Posted March 6, 2014 Posted March 6, 2014 I doubt they know anything about engine building Quote

That sounds mighty tight! Did you mean 0.002? Looking for my specs now for you (if I can find them again) Quote
Tricky-Ricky Posted March 6, 2014 Posted March 6, 2014 Have you not tried contacting the makers of the bearings/shells for the recommended clearance? Quote
GIXXERUK Posted March 6, 2014 Posted March 6, 2014 (edited) I doubt they know anything about engine building they seemed very knowledgable when i spoke to them, they are often asked about custom engine builds etc but I can only guess you speak from experience otherwise you wouldn't have posted thought they could advise on oil Edited March 6, 2014 by GIXXERUK Quote
evilscorp Posted March 6, 2014 Posted March 6, 2014 When going high hp the consensus is to go to the limit and some! I will be planning on running mine with the limit specs as shown in your table but only after 480-500whp (wont get it but hope to be close). The guys over the pond run 0.003" and 0.0032" there is an active thread on it at the moment on another site Quote

evilscorp Posted September 2, 2014 Posted September 2, 2014 (edited) I would rather we start putting up our own findings if anyone has them, I will in a few months time hopefully now my pistons have arrived. Wiseco recommend 0.0035" on my pistons normally they will give you a guide when you order. Edited September 2, 2014 by evilscorp Quote
