Torque Controler!

[robbieraver]

what are peoples views/opinions on torque controllers for 4WD systems in GTRs. I am refering to a electronic bias adjuster for the front drive.

Good? Bad? What do you think, if you have one installed feed back would be great

[robbieraver]

really,

not one single comment!

hmm...well I think they make a huge improvement in 32s in particular. But I would say that I sell them.

Are you interested in something in particular about them?

[robbieraver]

hmmm yes you would say that, what i was just after was just some positive/negative feed back from people who have them installed, i know how they work and why you should put one in, but i want to know from drivers what they think.

how much do you sell them for?

acually one question, do they put any stress on the clutch packs in the transfer case.

details of our controllers are in the link in my sig, and I don't want to make this a for sale thread...

First up, if you are only looking at street driving there's probably not too much point. Where they really help is allowing you to tune the balance of the car in corners, you have the car's natural balance, tyres, suspension and then you can get more or less fwd to change attitude on corner exit. Also obviously helps in the wet with reducing wheel spin, presumably the same for big hp gtrs in the dry too.

Yes they do put more stress on the clutch packs, you can burn them out running too much front torque for too long - they are not designed to transfer significant torque all the time. We killed a transfer case at targa tas 2 years ago on a 50klm stage through snow running full front torque all the way.

In the end, the 32 had too much rear bias and a controller can fix that - you leave it on say 3 or 4 and enjoy the improved balance. Nissan obviously agreed they changed the system to have more front bias in the 33 and 34 - I have a stagea daily driver and it's front bias is much more than the 32 (it happily power understeers every time you floor it)

thanks for the info, that is the same sort of driving il be doing, not so much targa but hill climbs and track work, ive heard of one or two dead transfer cases down my way (melb) but thats some thing to keep in mind.

cheers.

i run a torque controller supplied by duncan

and it works very well for us, we have done alot of racing over the two years it has been in the car(hillclimbs, sprints & tarmac rallies) and we are still using the original transfer case and we have not had to rebuild it.

i will say one thing though, if you 4wd system is not working properly (as most r32's aren't when they get to this age) all a controller will do is speed up the process of destroying your transfer case

oh & another thing, we did try a different torque controller that used a dial with percentages(10 stage adjustment) being directed to the front, this was a very sensative system and if you dialed in too much it would have killed the transfer case in a heart beat on circuit, not as bad for drag racing though.

Take you GTR to Racepace then.

They modify transfer cases inhouse
