What Diff are you running?

[Deleted]

So I have a question for the Mevabusa builders.

What Diff are you using? What ratio is it, and can you alter the ratio and overall speed to a certain degree with different sprockets?

What I need to know is if I fit an LSD Chain Diff for say a Sierra so 3.14 ratio, and my engine is revving high but not producing much speed, can I alter how this works simply by fitting smaller or bigger rear sprockets?

i'm totally lost on the understanding of differentials and what is going to work best on a 1000cc V-Twin engine.

Cheers

Hey Nick,

I am using the Radical/quaife LSD chain drive differential, with integral reverse. An absolutelty brilliant pice of engineering. Drive ratio's are very much adjustable via the fitment of different sprockets. Both forward and rear sprockets can be changed. Pushihng for higher top speeds reduces acceleration, and opting for quicker acceleration times reduces overall top speed. Consideration into main uses for the vehicle need considered for best ratio's. Again though it's not too difficult to chage ratio's later, especially with the split type rear sprockets.

Here is a useful link to help playing with different power plants and drive ratio's. They can also supply differnt diffs.

My diff can be seen on page 6 of my build diary.

I hope this helps answer your questions.

Just took a brief look over the pictures on the build and photo bucket, this is exactly what I want. I look forward to seeing it in the flesh

Many thanks, you have changed my direction and thoughts to diff now

I'm also running a quaife diff but very different to marshabusa's I'm not sure on exact details.

I think this diff is in the region of £1400 and the other chain diff is up around the £2000

£3500 custom diff I was told off the guy I bought if off for £500 bargain. I don't no much about them tho,it was in his huyabusa race car.

you have a forward/reverse unit I believe.

[hightower]

Yes Stuart 6 forward gears 6 reverse gears, may even attempt world reverse record haha.its 102 mph I believe

Hope you have big mirrors, and bigger balls!

[hightower]

Haha mawdo I was just saying its possible but highly unlikely I'd bet its mega hard to get much over 40 mph.

Its a beauty

But I think at £2000 its gonna stay a thing of beauty and I will have to re-think it.

What pound springs are fitted on the Mevabusa front and rear?
