Replace The Oem Awd Control With Manual For Drag?

[topspeed.ua]

Hello. I am interested if anyone here changed the AWD model to mechanical launch? I know many drag GTRs just put the 20Bars of pressure into the transfer on the launch to make it 50-50 split and then release pressure during the run to 0 bar to make it 0-100. Do you know any device that will do this? Not controlled the factory pump which is unacurate and not reliable, but the completter replacement of stock parts to mechanical pump that makes pressure off the line and then releases it. I know many people on drag skylines made a kind of handbrake that pumps the pressure there before the launch and then release it with launch controll solenoid. do you know exactly how to do this?

Anyone knows this info?

[Duncan]

nope.

But I assume they would use the stock pump and a programable ECU with a PWCM output to control the pump based on wheel speed input or something like that

Which model GTR?

I remember hearing the Australian Gibson racing team used to reprogram the map in the R32 attessa computer.

seen a very similar thing on Ebay for a shiteload less than that lol

Hydralic handbrake and a ball valve/solinoid valve and a pressure guage. Apply pressure to the clutch actuator to the desired pressure, lock the pressure with the valve, launch, 2nd gear- open the valve, drive over the finish line.

Very very simple.

A lot of the torque controllers on ebay will not do what he wants...especially the only one I found when searching on ebay

[bozodos]

there was also a guy on the forums whose name escapes me who makes these kind of torque split controllers, though it appears he wants something to replace the OEM pump as well?

something like this

Then add a pressure gauge inline as well as a brake line lock.

put the switch where you will not need to take you hands off the wheel.

Is it the Ruzic Engineering one that you are talking about?

[bozodos]

Probably is, he has it in his sig

just to clarify, the only controller that is any use for drag is the HKS Kansai one linked aboe, and they are very hard to find.

Every other attessa controller from the ebay one ($15 of parts for $250) up to mountainrunner's excellent ones use the same basic technique of bending the standard signals. The standard system already puts as much torque as it can to the front in a straight line so these controllers cannot increase front torque for drag use. They are absolutely excellent for track use though....

Agreed, the only difference is mountainrunner / ruzic engineering one is sooo much smarter than the ebay version. Either way, it was not designed for a drag situation.
