Looks like XFT need to engineer a whole new drivetrain for the BA-FG Falcons, Utes & Sedans.

Too Much Power!

Got that right, one thing we didnt do was go there short on grunt

Thats a bit of a bugger fella's.

And John so close to a 11 mate.

**Bluepower** · 20-10-2009, 09:14 AM

Some good times there, hard luck on all the breakages though, collectively, a lot of kilowatts there on the day.......

Good to see the KB ute relegate your F6 to "2nd" place in the stable mate, the dyno is nice, but when out on the blacktop, the F6 just paid the cost on it.

Well done again, and a nice 1st pass for the developmental KB kit

Were all these breakages factory parts or aftermarket?

Mostly factory pieces, Phil's Aussie record holding manual F6/XR6T broke a billet halfshaft though. Most of the manual trans cars broke halfshafts due to the new triple plate carbon clutch which has "limited" forgiveness on the start line and grips up almost instantaneously after the pedal begins to slide out.... very nasty.

Thanks Daniel. KCDR thinks the result of my billet halfshaft breakage a while back was because the factory diff bush and hat let go first. Here's hoping for the future!! Especially now with a new triple plate clutch too.

Soooo close it wasnt funny.. A bit of setup with the ute will work wonders. At 121mph I should have a bit left.

My ute did me proud. Worked it hard and drove it home

Must say my Texralia clutch (Single plate 800whp unit) did extremely well. No slip etc. Only problem is it took me 5000km to get the shudder to go away and after Friday its Shuddering a little again.

We had the bushes all done and the Auto cars were all awesome with NO hop and great powerdown.....

BUT...

The manual cars with their grippy carbon clutches were absolutely brutal, the first 1/2 hour was like an episode of Death Race 2000, with cars smashing all over the track. Honestly believe that a steady driving technique learning curve combined with the move to slicks and frontrunners is the only way these clutches will work with a manual trans.

You blokes are way too brutal for me, I don't think I could bring myself to belt the Scud so hard.

I have never heard about such a large number of driveline breakages in the one event. As I think dan said - it speaks volumes about the grunt every one of those mad cars is producing. let's face it, these vehicles don't exactly have weak drivelines even in stock form, yet alone 'upgraded versions. Interesting that once you remove the clutch and pressure plate as the 'weak' link, something else almost guarenteed to fail.

thanks for sharing.

Oh, incredible MPH by Dan and Simon, I would kill for a run in either of your cars, the in gear roll on acceleration must be simply out of this world. awsome.

If you go out again John, do your self a favor, get some good rubber like MT streets, if you can put some smaller brakes on the back and run 16" MT's, way grippier than the 17" or 18" MT's due to the bigger sidwalls, some good heat into them and a good launch should get you into the 1.7's on a good track, which will take you well into the 11's. Or go all out and run full slicks, but changing brakes front and back isnt most cup of tea.

Manuals and these heavy cars, slicks are the only way to go, more forgiving on the driveline and with traction as manuals are so violent putting power down, and more consistant launchs.

Yer, After mine broke the axle hub inside the diff it destroyed some of the internal diff parts aswell, Its got a truetrac being fitted today and the tailshaft got squeezed a bit out of shape aswell. SO its getting a bigger tailshaft, Only thing left is axles and ill take it down again with slicks and front runners. Utes had a bigger tailshaft fitted so its ready to head back aswell.

Video for the day will be finished this wekeend.
