I have a highly modified B5 chassis 2.7T ( 480 HP ) that is used on the track only. Other than an external air to oil cooler does anyone have other changes to improve the capability of the oiling system ( high press. hi volume pump / accusump......) tks

 

you can get bigger turbo oil return lines, and i think VAST sells an external cooler kit.. but i cant think of anything else.. sorry..

 

well your very limited on the supply lines going to the turbos bc The oil is fed through the valley and out the back of the block to a distribution block that splits it to two lines.

 

Higher pressure won't do you any good unless your changing bearing to journal clearances. It was engineered to run at the factory pressures. Not to mention you run the risk of blowing oil through oem seals.
An Accusump may help prevent starvation in high G situations (i.e. hard turns, braking, acceleration)
The Accusump's advantages for preventing dry start-ups would be beneficial regardless of the cars performance level.
Adding coolers and bigger turbo lines would probably be sufficient for you application.
Although keep in mind that. bigger lines are still only as good as the orifices that feed to them and the ones they feed into.
