Adam, the Banana uses a Zen Dry sump, and it works very well. I cant remember what the retail is on the sump kit, 2.5 to 3k rings a bell with me, and cant remember if that includes the tank or not, but ultimately its the safest route if serious track work is your bag. Dont forget to factor in braided oil lines too! Steven

With the smoothness of your driving and the increased tyre sizes, it was going to be pushing it at probably the 2nd worse corner in the Uk for oil surge. If you were running a standard baffled sump as well, it is still a problem, as you arent carrying a large volume of oil. Combine this with just having had 1km at high revs, there hasnt been sufficient time for the oil to return to the sump pan IMO. The best thing we did on the Banana was switch to a dry sump. 8+ litres of oil being stored in a non surge environment has worked very well indeed. If i was in your shoes now (having been there before), and you are going to be doing more track stuff at this level, i would strongly recommend you save up for the dry sump, because if you dont, the next time your engine goes due to oil surge, you will be kicking yourself. Remember, your failure appeared fairly mundane, ie, no rod through block, no shrapnel everywhere, when that happens, the costs of rebuilding become far higher. Give me a shout if you want to chat about the dry sump more. Finally, WELL DONE on a cracking season

Watch that gauge on the left Scott on your first lap at the end of the pit straight and round coram! From memory thats your oil pressure gauge? Dry sump time!

Nice one Chris

Nice thread Archie. Hopefully i will get up there (Doune) next year and see what all this fuss is about. Steven
