Talking to some track dudes some have said they gave up driving T4s due to loosing to much oil on the track and no matter how big the Acusump was, they still burned out bearings. What is your solution to this problem? THNX (IMG:style_emoticons/default/beer.gif)

You really need to be running a three or four stage pump to get the maximum benefit from a drysump system. The valve covers hold a bunch of oil and you have to be able to suck that oil out and not wait for gravity to takes its effect and it drain back to the sump.
If you look at real race engines you will see at least three and four pickups on the suction side. On the V8s oil is sucked from each valve cover, the oil pan, and the lifter valley. The CB system doesn't do that. It pulls from one place, the place where the T4 has all the problems to begin with. |

Multiple pick-ups or multiple pumps? There's not really alot of space in a 914 for a much bigger/longer pump. How many pickups in a 911? I've never seen the inside of one. What's their sump tank volume? |
