Has done a stack of kays...330rwkw will get you an 11 with a ZF even with a 2 second sixty footer, as long as everything is working like it should.

The box though can handle more power, it is just a matter of how long it will do it. Link to comment Share on other sites More sharing options...
james.jamble New Member 8 Member For: 9y 9m 6d Posted 18/05/15 12:39 AM Share Posted 18/05/15 12:39 AM I had 318 kw when my bf2 had 120k on it. Then at 135k got 370kw. Gets driven pretty hard. But if I'm going to be boosting I keep it in manual mode. Got a service at about 130k. Done 145k now. Slips when changing gears at high boost in drive. And doesn't go into 4th in manual mode at full boost. But that only happens when gearbox Is hot. I don't have a ZF tune or even a tranny cooler.

Had it like that for three years. I've also got a dyno chart from a ute making 425wkw and 900nm on a stock box. They will hold it. If but for a while. If the shaft doesn't go the clutches will Link to comment Share on other sites More sharing options...
