CRV 4wd question

[Zinc]

Is it possible to send more power to the back with the CR-V realtime system, lets say 60 front 40 back?

[HondatechAV6]

no, no major power is sent to back during normal operation. only when the front wheel/s slip is power sent rearward.

i'd need to explain how the dual pump diff works for you to understand.
well, here goes:

the dual pump is just that, two pumps with a clutch pack and a mini diff.

the front pump is run by the driveshaft, which is driven by the front wheels basically.
the rear pump is run by the rear wheels. when the two pumps are driven at the same speed there is no pressure build up.

when the front wheel/s are slipping, more pressure is built up in the front pump than the rear pump and it compresses the clutch pack, enabling 4wd until the speeds synchronize again.

Awsome, shitty yet ingenious lol. So theres no way to have the pump just engage the clutch all the time?

I was wondering because i saw a drifter integra on the net somewhere, and it had a CR-V drivetrain.

well, built in the hydraulic circuit is an overheat valve, which might open if engaged all the time, especially during turns. it has to slip a little. i personally like it. no electronics, no trouble codes....

the only problem is the fluid breaks down as soon as every 30,000 miles. you get a shudder when taking tight turns.

Well do you think its worth the extra weight to put it on a Civic? With 160whp?

[HondatechAV6]

nope. extra weight means extra slow in this case. there is a lot of power eaten up by the drive train on that crv. and it's a 160hp engine too, i believe.

the new 2wd version of the crv FLYS compared to the 4wd version. it's completely useless unless it's raining or snowing and you insist on driving aggressively.

makes sense. thanx
