Prototype Driveshaft
Discussion
Hi Guys,
I thought I'd start a thread to document my testing of a prototype driveshaft that's been fitted to my Monaro by Monkfish.
In principle the new shaft is similar to others already on the market being thicker than the stock drive shafts this cancels out the harmonics that cause axle tramp. The extra benefits of the MF driveshaft are that it comes with good quality CV joints and is sold as a single item. My reason for wanting this isn't to build a stronger drive train but to stop the dreaded axle tramp.
My main issue isn't that my Monaro axle tramps the whole time. I never usually have an issue under burn-out conditions when the rears are properly overwhelmed, my issue typically occurs when on or slightly above the threshold of wheel-spin.
I had the shaft fitted yesterday and on the drive home even though the roads were drenched with loads of standing water I was able to provoke wheel-spin in a variety of circumstances and based on my initial drive it's all but eliminated my axle tramp except for the most extreme cases of provocation. Given that my engine moves a significant amount under WOT due to the extra torque and also has a modified propshaft which only has one rubber doughnut rather than 2 on a stock setup I wouldn't be surprised if this new MF driveshaft completely eliminated axle tramp on a stockish setup.
I'll continue to test and report back once I've found some dry roads to conduct some more "testing" on. Any donations towards my increased usage of MPSS's will be gratefully received

Interested to hear how you get on 
Mine can still do it occasionally, presumably my BMR one would undo a lot of the beneficial difference in size provided by the MF one?
Very good question. I don't have the size differential between the stock and prototype shafts but I'm sure Roger will be along shortly....Mine can still do it occasionally, presumably my BMR one would undo a lot of the beneficial difference in size provided by the MF one?

I have G Force ones fitted to mine by MF, 100% no tramp 
Yes but did Roger not have to do work with them to make them work and be reliable. Spoke to him about these some time ago and ive been waiting for something to come to light. Will need to find out more tomorrow.EmmaJ said:

+1 They are far from stock G Force shafts from what I understand as well.
What is the cost emmajI did ask for indicative costs and a figure of around £500 quid was mentioned. Don't forget this is only a prototype at this stage and pricing will no doubt be influenced by the number of units that are made

emma the ro is always going to suffer from axel tramp without replacing the rear end of the car
That's as maybe but given the reduction others have reported with G Force / BMR shafts having a home grown alternative that can be bought as a single shaft with good CV's can only be a good thing. Based on my initial testing I'm very happy with the positive difference this prototype driveshaft has made for me... Gassing Station | HSV & Monaro | Top of Page | What's New | My Stuff
