XR7 Dave said:Seems Raxles are pretty much junk these days.
That's not exactly true Of course, mine was just a bad CV joint, and not completely grenaded like others.XR7 Dave said:And of course if you run an auto you won't break them either.
XR7 Dave said:Anybody can break anything.
If you make sure that your wheel bearings are good and use the right tires you won't break axles. And of course if you run an auto you won't break them either.
Even with an auto you can rip them apart, I got two samples for you to see if needed.... .......Rich
XR7 Dave said:Go ahead guys, like I said anybody can break anything. Within reason axles don't break unless they are subjected to extreme shock loads. Rich, nothing you do with your 800+hp monster applies to the 250-300rwhp cars that busted shafts at the shootout. My point was and remains that people who break things are abusing them and need to rethink what they are doing. This applies to you as well.
Gary Kuhn and I have proven that axles will hold up decently at over 400rwhp if treated right. Others have proven that 250rwhp is plenty to break axles, transmissions, etc. if abused. That's just how it is.

When he hit second gear it went boom,,That was just making a power shift at speed....
As for my other car, maybe it is time for some "Strange 35 splines" & a nine inch rear.... Or maybe I have to just go to a tire that will not bite as much...........Rich...P.S. should have seen it tonight at our mini meet. Even the "Boy's in Blue" were impressed. They just told us to stop and go home or they would have to start writing......Boy were we lucky this time.........Rich
14.0 @ 103 mph was he spinning off the line? I ran 13.1 @ 103mph with leaky hg's. Does Chris have a auto or manual? Doesn't his et seem high compared to his mph?XR7 Dave said:Well, things went um, ok.
And the other AR was Chris Zwemke who ran - I think - 14.0 @ 103mph with his bone stock engine and stock IC suffering from 24-25psi boost. He didn't break but left early due to family concerns. He made 300rwhp on the dyno on Friday.
And that is what happened.

1] Scott was on "Drag slicks" when he broke at the bash.XR7 Dave said:Rich, of all people I would think you would have gotten the message by now. Let me spell it out ONE MORE TIME.
1) New wheel bearings! In almost all cases broken axles are accompanied by bad wheel bearings. A lose wheel bearing will allow the wheel/axle assembly to resonate under load. We all know this type of action will weaken and break parts. Think about how many HB bolts have been broken and why. The same thing applies to axles.
2) Shock loads. As a veteran racer you know that shock loads break things and it will break the weakest link. By purposely creating a weak link you can sometimes create a safety valve for more expensive and hard to replace parts.
3) Wheel hop. Three words. Don't Do It. I can't count how many 5spd guys will tell me "yep, wheel hop was bad on that last run". You don't "deal" with wheel hop, you eliminate it.
So what is the solution? I've posted this 100 times. Here's 101. Use race tires at the track! Not drag radials either. Everyone repeat after me: I WILL USE RACE TIRES. There are reasons that drag tires are made the way that they are. One of those is that they have sidewalls that flex and absorb energy. No drag radial will do that. The construction of a radial tire makes it impossible for the tire to absorb shock like a bias ply race tire will. Drag radials will be sticky but they will not absorb shock.
This doesn't mean that you can't break parts on race tires, it just means that the axles aren't breaking due to HP levels. They are breaking from excessive shock loads. And yes, dumping the clutch at 5000rpm in a 400rwhp SC is excessive.
Sounds like you got lucky again huh Rich? I do think that unless you just have more to prove to someone about IRS that you are definitely overdue for that 9".

2] the wheel bearings were less than one week old on both sides.
3] Wheel hop is not something that he will try to drive thru. He has been told more than once, and has seen what happens when others keep their foot in it.
4] He made a shift just as you do, but his broke parts.
5] As for my "IRS" setup, it is always good to see just how far you can push the limits.. David N. asked me just what to look for out of his rear set up.
6] sometimes it is just fun to have fun........Rich
