just bought my first radical. advice greatful
Discussion
hi all.after a year or so of looking,and posting on the forum i have bought my first radical. its a zzr 1100 clubsport and im hopefully collecting next weekend!
the only issue i can see is it has no dry sump setup! im relatively experienced with bike powered cars but nothing with the grip of the radical.or mid engined.and up to now had no issues with oil surge
it has new quaife diff,new 0 hour engine and extremely low chassis mileagerace flatslide carbs but no dry sump!
how critical it the dry sump in the mid engined layout? as with it bieng a powertec unit and not fitted id assume it should be ok? cheers

Just make sure you follow the Radical/Powertec/RPE guidance on the oil level and you should have no problem, worry ye not, remember that although it doesn't lean like a bike it is in the correct orientation unlike the Front engined BECs which probably do benefit from a dry sump setup.
FYI the procedure is check the level with the engine running and well up the sight glass, this should give the "correct" amount of overfill to protect the engine.

Well done!
As I've said before Clubbies are great little cars.
Whether or not oil surge is a problem depends on grip (ie what tyres and aero you run), what you're doing with the car and how diligently you check and maintain oil levels. Plus, with a Clubbie I'm guessing that you won't have engine data logging and so won't be able to see any transient downspikes that don't wreck your engine immediately but over time build up hot spot damage and worn bearings.
So, if you're worried you only have to fit an Accusump with an electric valve to put a floor under your oil pressure: https://www.merlinmotorsport.co.uk/m/ACCUSUMP.
I use a 2 pint reservoir with a 35-40 psi electric valve on the Force (a car that generates 3g Lat Acc at 80mph and -4g Long Acc under braking, but has a wet sump). We have extensive data logging on the car and monitor oil pressure regularly via both AIM and Life systems and what I can tell you from that is that the Accusump works!
If you're driving on circuits I'd suggest you think about a 4 pint tank and electric valve. It's going to cost you a few quid but is still a lot cheaper than an engine and does give you peace of mind.

thanks guys! especially LCM for the continued help! it just so happens that i have an accusump in the garage,which i was going to fit on a gsxr1000 motor i was going to use on another car which is now sold. cheers
Good man! 
Just invest in an electic valve of at least 35-40 psi (which isn't tuppence) and drive confident in your oil supply.
