Back from the nats, was a good day but not for the supra first run no traction of the line as the track was still damp and we had a bad miss as i was eating spark plugs but we did a 10.7 @ 190KMS, on my 3rd run i smashed my diff doing a burn out, but i do know there is a 9sec pass in her but its getting it right.

Good stuff John a new diff I think I heard 10.7 you must be laughing.
Your cars probably good for a 9.7 once fully soughted what are you going to do about you breaking diffs I no Graeme@ Croydon's was having similar problems when he was at the same stage with his car about 3-4 years ago.
I heard Rayglass was doing 1.0 60 footers F**K Me sounds like 6 second material to me

I no Graeme and Justin were using the small auto diffs and they are'nt up to the power you guys are making I no Justin has just bought a Big Torsen diff from a friend down here I personally don't think it will fear much better with 7000 rpm launches and all.
I went round there today. Previously hes split the head casing apart. This time I didn't see that (only had a quick look) but I think the half shafts have turned inside the head because one of them is stuck in there so tight they cut it off to remove it. The bolts that hold the crown wheel to the head have all sheared off. IMO not worth replacing with another factory diff since this is the 3rd or 4th time its happened (I think??), and I don't believe the type of diff head used will make a difference, since it's a shock/complete failure thing rather than a slipping/opening up issue.
I have a trd 2 way diff, after cracking the torsen carrier housing. my viscious shift kitted auto was most likely the culprit. a lot of the big power supras in japan go to a TRD lsd,so i can assume they are stronger. however, it doesn't stop you breaking the pinion/crown wheel combo.(which i heard that the croydon supra did a couple of times.)

Blake we have a trd diff on its way, i can only try it i do now the next thing to go will be the crown wheel and pinion and we are looking into that now.
