I dont know a huge amount accusumps other than the fact they dont have a great reputation and the problem is that with a one off installation is a cs, you'll be hard pushed to know whether it is working or not. I wouldn't go there myself.

This may be a daft question but what is wrong with the std wet sump system and what do you gain with a dry sump??

Dry sumps don't suffer from oil starvation caused by oil serge. Most decent baffled tanks will cope with most tracks in the UK however I think Rockingham is a good one for killing cars. There is also less drag on dry sump as the crank isn't paddling through the oil in the sump. Downsides of dry sumps is added complication and additional weight.

Thanks Rob. Sounds a bit six of one and half a dozen of another!! I think I will stick to the wet sump avoid Rockingham and keep my fingers crossed!!

I have an Ultima and there has often been doubts about the real effectiveness of the Accusump as a lot of other owners use on their cars but as a rule, they seem to be effective enough for the occasional track day but if you are serious, dry sump it, it is the best (oil starvation wise) fail safe you can make.

One other benefit of a dry sump system (done right) is you have a lot of oil in the system so if your engine burns oil, you won't be in danger of getting low on oil in the system in long races. It also keeps the oil cooler and cleaner (generally) because there's more oil and it spends less time in and around the engine than a wet sump.

IMHO every race car should have a dry-sump if it's possible within the rules etc. Most race cars don't and various types of baffled pans are usually good enough but the longer you run the car, the more benefits you'll get from a dry sump.

With our original Powertec 1000 (US spec D-sports motor), it would burn ALL the oil in a 3 hour race, it was impossible to endurance race it without a dry sump just based on it's oil consumption!
