as the title say's, I ran my car at the sunstates nationals on the week end, I had put a big effort into this race, and I am on a bit of a low now, but just trying to get some positives into it,

I tuned it up untill it was making 598rwks, and that is through a c4 auto and big stall, so there was plenty of power to be had, but first run I detuned it about 50kws to see how it runs and that for the first run, she left good.

one positive was it 60fted well on the first run, she ran a 1.36 60ft,

it only run a 9.5 at 144mph, but when I pulled the shoot, (for the first time) and it must have unloaded the front tires, and I flat spoted them (down to the canvas)and could not do any more runs for that night.

got some other tires over night, and first run the next day, I dialed in the full power straight up and launched it, and she went about 10feet, and smashed the diff, she smashed the centre apart in about 20 peices, and that was the end of my second day.

David,

That is an awesome effort with the IRS rear end! I still cant believe you went 9.43 with it!!!

Well done! Looks like it's time for a 9 inch now.

Cheers

Fantastic effort Dave with that 60'.

dude f*ck me your doing top stuff u should get the positives out of it because sh*t happens in racing and a 1.36 60ft is sex I mean look at what your diff has copped its done bloody well to last this long dont ya reckn. and the fact your out giving it all u can is what matters top stuff

btw 600 odd kws is a fair slog of power

Top effort.

What can be done to the stock diff and irs to take it further. After market centres are available but how strong are they? How far could you go with custom strengthening of the housing and cradle?

Hi guy's and thanks, yes still the t51r 1.05 turbine .73 comp.

I removed the exhaust and about 100lb of the good stuff inside, it has done good, I am not disapointed in the diff, I did not expect to last at that level either, the track was to good for me, I have been running at test and tunes, and to go to a fully preped track, I should have known better then to not stage the power,

I think I was startting to think it was indistructable, justlike I got with the stock motor, (you would think I would learn).

to thinkthe stock tail shaft out lasted the rest of the car has got me stumped, about 15 nine sec passes

and the diff only let go because I kept putting more power into it, and something has to give,

I have pictures I will get of the tires on the launch of the 1.36 60ft, it is hard to beleave the twist and flatening of these tires at full launch, I will post them up when I get them.

I am going to work for a few day's, andi will have a think about it all, I might go to the 9 inch, but I do beleave these can run a 8 with the stock diff, but I will have to be a bit smarter at it, not just throw power at it and hold on.

it is a bit out of my budget, otherwise I would have already done it.

If it held together it would have been a good time.

it's amazing what some components can take, I suppose it was a matter of when not if. Awsome 60' though

I know DBOSS put his 10 sec beast through serial abuse and the 4 speed still held up

well done dave at least there was one positive to come out of it all. I swear that car of yours must of been built early tuesday the way all the parts have held up.
