I'm going to be getting supra mk diff kit in the near future.
Could someone who has got one tell me what difference in driving I'm to expect.
I've searched and couldn't find anything.
Thanks
Jay.

 

I haven't driven with mine yet but I had it set up by Bara to suit the cossie road application, if that helps.

 

I found it puts the power down alot better,
quicker down low with it being 3.7 compare to the cosworth 3.6

 

Mine is a 3.9 so lower still

 

Thanks guys.
Mines 4:44 but that doesn't mean a lot when a rb25 should have 4.1.
Like going to a 3:9 I guess. I was running a 3:6. I have got a 4:27 that I was going too get made up. I'm expecting a massive difference. At 100mph I was at 3k on 18's. Could you feel the difference Dan??? Just :1?

 

I take it your s is for a track car ?
Want sort of power is the car ?

 

Yes pal track/fast road. 330 at 12psi. Soon to be 370-390. Diff only locks in a straight line. No good for corner exit speed.

 

Dan did you really notice the difference between the 3.6 and the 3.7??
I thought the cossies were 3.69 with the standard ford diff?

Cheers Paul

 

Be aware that the rear casing fails at higher power levels 500+ mk is making a billet rear casing to adress the issue so factor in that cost aswell as the diff and kit thiers a group buy going on in trader group buys mate suprised nobodies mentioned this

 

yeah it def felt quicker, maybe it was more because it the power down a lot better
I think it was only in bigger horse powered track cars that broke the casing,
could be wrong on that but,
touch wood mines been fine,
I ll not be spending money on a billet cover unless I have too

 

Wrong thread but any news on when we might expect deliveries?

 

Thanks guys. I work round the corner from mk. Spoke to mark and I'm not going above 400 anyway.

 

hi toby
the thread you need is in the traders section ,any questions updates will be in there mate

thanks mark

 

lol it isnt i was just letting him know of the issue with higher power and the fix

 

Standar diffs are 3.64

 

I meant that I was posting on the wrong thread, not you.
