Indeed it is! Like a charm. It actually broke the second hand shaft we put in. A shaft we found yesterday at a local wrecker. I think it was an aftermarket CV judging by the way it exploded.

We needed to replace the original FR shaft with this because the original shaft was over heating, and blew the boot off, send grease everywhere and overheating/welding the CV.

Just one of them things........

lol fences. and llamas.

every big (big) power running lots of fwd kills drive shafts and front diffs. the more front they run up to 50% the quicker they go, but the front driveline is just too small. I've got no doubt the only permenent fix is billet driveshafts and a bigger front diff....will require lots of hard work.

yep, there is no (easy) way around it really. the other problem that doesn't help is front driveshaft angles and again with the diff in the sump that's not exactly easy to cure either (unless you can just return the car to factory ride height which in this case is not practical).

Some guys in japan have made stronger front and rear driveshafts but the cost is pretty nasty. then again so is f**king everything else! like dundan said front diffs like to explode too and being in the sump there is bugger all you can do about it short of a full custom set-up.

the only practical solution is keep breaking the bits as they break. or mark's answer was "drive it less"... lol.

or mark's answer was "drive it less"... lol.

i wouldnt be locking that one in, eddie.

dont hi octane have some big dollar driveshafts?? or is the CV's thats the issue??

the japs have to be on to something surely... they have a few 1000hp gtr's getting around now..

is there a way that you can turn the front traction up and down with steering angle?? doesnt the hicas work of a steering wheel sensor??

what do the wrc cars use for front CV's?? i mean they are the the most hardcore 4wd thrashers on the planet.. admittedly they dont have 700hp and they weigh less with less traction... but still... gotta be some ideas there.

its easy solved just run less front torque. the rear diffs are pretty much indestructable (only about 5% smaller than ford 9") and the driveshafts are OK but casn be upgraded.

the problem is....the more fwd, the quicker they go....so in an event like this they have to run 50/50 and hope for the best.

plenty of options for driveshafts, just jap even have billet stuff on the shelf. its the front diff that is the big issue.

where is lofty....how are you guys going with front diffs....you guys have by far the most experience with trying to put big power thru the front in circuit use.

its true we need to run 50/50, we even built a trasfer case with a solid shaft so it dosn't have a clutchpack (very light weight) ,in testing car was very fast but front diff couldn't handle it. we punched the front diff assembly off the sump.

The problem is the front diff is small but if you run too much fwd under braking the load coming back into the front diff is opposing the load from the transfer case. the casting on the sump is the weakest link and because the front pinion and cownwheel

create a sideload (trying to spread apart)they punch the diff off. when you look at a broken one you can see they will take that load in the power delivery direction (on power pinion has thrust direction against sump) but they are not strong the other way. result was to limit how much fwd under brakes (no broken diffs since)

Hi all,

A bit of news on something we have been organising behind the scenes with this driver and his manager in Japan ;) ...

Toshiki Yoshioka, Works Bell sponsored D1 driver and winner of the 2008 Formula D Las Vegas event, is coming to Australia for the World Time Attack Challenge.

Yoshioka has been invited to compete in the drift section of World Time Attack Challenge, and will be driving a 475hp 1JZ Toyota powered S13 in Sydney.

If any of you have ever seen videos of him running in D1 or Formula D, you'll know how spectacular his driving is.

We're going to be very busy at WTAC with Yoshioka's visit, our sponsorship of Mark Berry's Advan R34 GT-R, and a number of our customer cars running in this event also - it'll be an incredible event !

More info about Yoshioka's visit, a video interview with him, and a video of him competing in Japan can be found here ...

either way ill drink him under the table

by the way its fatz here on sato's computer

Agreed with Lofty, we're also disengaging FWD under braking in an attempt to alleviate the front diff falling off.

I do think last week's CV was just one of those things. The boots have torn apart on this particular shaft before we found a fix for that and we've re-booted and re-packed this shaft twice I think.

    • Seemed to be good when Jeff owned it but they did a shit job on my car, probably worth a think before spending 10's of thousands of dollars where they might be cutting corners
    • Starting with issues 1 - 5, we have already run into a problem...!  Issue #4 contained 2x front brake calipers, instead of 1 caliper and 1x steering knuckle. Will have to call DeAgostini on Monday to sort it out. Anyway here's some photos.  Issue #1 is the front bumper, headlights and number plate. Issue #2 is the front wheel (with "We produced with spartan air." text on the centre cap!) and tyre, the front lip spoiler and cylinder head cover with ignition coils under the centre cover... which will never be seen again. Issue #3 is the bonnet and cylinder head. Issue #4 is the front strut, brake disc (with laser etched metal discs) and brake caliper. I stopped here because of the issue with the missing steering knuckle.  Next update will be #5 - #10 in a few weeks.
    • DeAgostini is one of a few companies that release quite large (the largest commonly available size actually) 1/8 scale models in a series of weekly issues over 100 - 110 instalments.  They release different models for different markets and DeAgostini Japan have release the BNR32 Skyline GT-R Nismo last month. I've made two of these 1/8 scale sized cars (one an R35 GT-R from 2012 - 2014, the other I'm just about halfway through, a BNR34 Skyline GT-R from the 2Fast 2Furious movie) so when this R32 was announced there was no way I could ignore it as it's my favourite out of all Nissans.  Each issue costs around $20 so it costs about $2.2K when completed. I suppose it is very expensive for what it is, but the quality and details are really very good, and there are many "gimmicks" like fully functioning exterior and interior lights operated with a remote control, working steering, all doors/bonnet/boot/fuel lid open and close, the side mirrors fold in and it even has a speaker for the engine revving sounds when you turn the lights on.  Each issue comes with a magazine that tells the story of the BNR32 Skyline GT-R Nismo from the first design stages of the BNR32 to Group A homologation and the various racing version that were run in the Japanese Group A and JGTC, and Australian Group A.  So I plan to update the build in this thread 5 issues at a time.  https://deagostini.jp/r32/?srsltid=AfmBOooKjxDc4EUK2rmXqMBPgyHfFJ24s4oEPJBNpnF-lFlsRoW0PE6P
    • As per title.. has anyone used so far? Keen to hear results, comparisons. In the market for a new mani for my new turbo. Any issues cracking?
    • Re read everything that has been written about this in this thread.. Let us know if you're still confused.
