r32 gtr diy torque splitter

[hippy]

A friend of mine just got a r32gtr ... nicely modded and produces alot of power ... dont' know the exact numbers but its fast!! ... N1 turbos, big cooler, runs lower boost than normal with those mods, probably for reliablility.

anyways he says that his car oversteers alot in corners and he gets freaked out. he came across this article

http://www.skylinesaustralia.com/forums/sh...+torque+control

and was wondering if any of u guys have tried it?? or what other things have you tried to make it handle much better in the corner?

also, the car has ohlins on it, and slightly lowered from what i can see, i'm not to sure about what it has for struct and sway bars, i'll check that later.

thanks

sway bars, tyres, ride height, wheel alignment, all seem to play a roll in it

if you power out of a corner hard i find the arse does come out, but not like a rwd, if you keep on the gas pedal, and point it where you want to go (dont overcorrect) it corrects itself... thats the idea of the ATESSA, if you dial it up to 50/50 full time i think it may do bad things

[hippy]

thats what i was thinking ... but my friend seems convinced that the guy in the article seems to know what he's doing ...

This link is an interesting read. Deals with modifying torque split control.

GTR's are complicated beasties eh?

Revision Ah, sorry for the dodgy link. I'm not subscribed to Autospeed either. If you try this http://www.google.com.au/search?hl=en&ie=U...+g+sensor&meta= and click on "godzilla tamed" it gives you the complete article for some reason.

if u use ne other options, other then 50/50 full time rear and normal, the transfer case will be constantly slipping wearing it out super fast, as with 50/50 your atessa pumps will be constantly working therefor will wear out faster, best just to get used to the way the car works, learn to work with it and it will be unbeatable around a corner.

i think thats the same article as the one i posted in the first place ...

Hippy, can you tell me where you posted it so I don't have to subscribe to read it?

Cheers,

Rear Steering is not your friend, the first thing I would do is lose the HICAS. Get rid of that fidgetty rear end, that makes you worry that it's going to let go. Tell you friend that the race GTR's never ever ran the HICAS, that usually seals it.

u dont have to subscribe?? .. well i didnt..

in my first post i mean

I've been doing some sniffing around and it seems that the 32's are more tail happy than the 33's due (partly at least) to the tolerances in the transfer case clutch pack.

The 33's clutch pack is partially engaged at all times. This should be achievable with the 32's transfer case as well by using enough of the thicker packers in between clutch plates.

I haven't got an r33 manual to check the figures. Anyone who has, please check it out and let me know.

Also investigating retrofitting v-spec 33/34 ATTESSA computer for faster reaction.

Hi, the car Hippy is talking about is mine.

I've just ordered a Super HICAS electronic locking kit from GRID in Japan

http://www.grid.co.jp/en/prod/prod7.htm

Should take out the unexpected twitches when on the limit. I hope the package is as reliable as physically locking the system, has anyone had any experience with this gizmo?

Sounds interesting about retrofitting either the R32 Attessa-Pro from the V-spec models (If you could ever find one) or a v-spec 33/34 attessa system. I recall reading somewhere in HPI or Zoom that apparently the controller in the attessa (non pro) monitors data @ 100 cycles per second, where as the attessa-pro is much faster at 400 cycles.. does anyone know how much of a difference this would make?

[GTRman1992]

I have that article and he said no difference at all. Apparently just feels a bit smoother in the car but as far as handling goes no difference.

I think the different software would probably give you the difference. I found a post on a UK Skyline site where the guy said he fitted an R34 ATTESSA and the car then handled like the R34.

Ok apparantly the link doesn't work once pasted.. though just do the godzilla tamed google search and full access is granted.

GTRman1992, this is a taken from the last paragraph of the article.. perhaps you missed it?:

"It's hard to believe, but the electronic mods have made more difference to the handling of the GT-R than any other suspension modifications I have ever made to a car. And that includes the changing on previous cars of wheels, tyres, sway bars, springs, dampers, bushes - the lot. The difference simply cannot be overstated. And I might add that now the cat's out of the bag, a number of GT-R owners who had previously told me how wonderfully their cars handled have modified their torque split control system..."

Check it out guy's, some interesting points are made.

Yeah the link didn't work, but the google search did. Thanks for the tip Conrad. Reading now!

I take everything Julian Edgar says with a grain of salt. Having read a lot of what he has written over the years I can say I believe that he has some weird agendas. That article was published many years ago and I have personally tested the mods out on the road and the track. All it does is make the GTR understeer all the time, maybe this made him feel safer, but it just made the GTR slower. This was particularly noticeable around the circuit. I am not the only one with that opion, the article has been discussed and dismissed by many people.

It is also worth noting that the car involved was Julian's own and he sold it shortly after and has done nothing but whinge about it ever since. Maybe he has tall poppy syndrome, because he appears to like nothing better than knocking down icons.

My opinion anyway

Yeah, after reading the article I didn't really find it very helpful. All he did was basically bag the GTR and say how bloody special his liberty was. and then describe a mod that no-one who's not an electrics genius can make. Very helpful....

[hippy]

basically from what i gather from the mod is that it turns the gtr into more a full time 4 wd?? amplify the sensors to get the attessa turning on earlier ... thats what its basically doing.

[funkymonkey]

easily done on an R33 or R34 GTR... but on an R32 the sensors are hydraulic
