2016 CMC Rules

[mach1]

---1) Tyler Gardner / TX / #013 / Phone
---2) 7.11.10 (new)
---3) Ford 5.0 cars may use aftermarket internally balanced and forged crankshafts
---4)
---------->a) 4 5.0 catastrophic crankshaft failures in the past few years
---------->b) Will promote series growth because of reliable engines.
---------->c) Rule change is only for durability and there is no performance gain
---------->d) When mine broke the cars behind me lost control, oil and sharp metal on the track is a serious safety issue that could cause loss of equipment or life.

Examples:
Tyler Gardner CMC 013 MSR-H 2015
Michael Mosty CMC 11 2014 and 2011
Wade Zimmer CMC 2015

I think I'll stick with my cracking k members.

I think I'll stick with my cracking k members.

I could have fixed a cracked k member and been racing this weekend instead of driving all over Houston and buying a motor that ended up not working out
Can someone post pics of the k-member cracks in question?
Also, I have a LS1 k member for sale if anyone needs one.

[QUOTE=BryanL;73519]Not sure on all of them of course but I had experience with it cracking at where the factory weld was done. The factory weld isn't the best from what I'm told-chalk up another win for the Mustang.

I looked at the one on my S197 Mustang and I am thinking that it has to have been heat treated after it was welded out. It is well supported by the inner fender/shock towers too, but if it were to get bent or cracked I doubt it would be repairable. The car maintains alignment remarkably well, in spite of my occasional errors in judgment.

I grafted a 79 Trans Am front sub-frame on to an old truck once, and the factory welds on it were the worst I had ever seen. I re-welded the unit before installing it using a skip welding technique. All of the data I have been able to find regarding modification of production car front chassis members for racing, calls for skip welding reinforcement to maintain as much of the original temper as possible. Welding up a beefy repair in one spot creates a soft area in the part that will yield causing alignment issues or failure to the adjacent areas. I wish I knew more about the K member on the LS1 car.

Were me, I think I would gather as much information as I could about the common failure points in the K member, find a good K member, and Tig weld gussets in the problem areas being very careful to control the heat affected zone.

On second thought my 69 Mach 1 had some of the worst welding I have ever seen. During resto I found holes blown through it and giant mig globs with wire stubs sticking out. All covered up with factory seam sealant. I am guessing the welders at Ford bought a lot of beer for the pooky shooters to keep their jobs :-)

I am trying to figure out what is in the pipe for 2016, I am going to submit one for the slotted rotors that we discussed a few months ago, do we have anything else?

---1) Tyler Gardner / TX / #013 / Phone
---2) 7.32.8.3
---3) Rotors shall be cast iron only and may be vented. No cross drilling is allowed.
---4)
---------->a) Will decrease series cost because slotted rotors are much easier to find.
---------->b) Will promote series growth because slotted rotors are much easier to obtain.
---------->c) Slotted rotors provide no apparent competitive advantage and we could share rings with AI in a bind.

If we can get this passed, I am trying these next, hopefully no wallerin issues.

How long will those things last?

I don't use a stock k-member. I put a UMI road race k-member in the car in 2006. No cracking to date. http://umiperformance.com/catalog/in...roducts_id=680

Reverse has gone out in my T56 multiple times.

RCR #4 and #5 are up if you guys would like to comment, this is for slotted rotors and better cranks for the fords.

What's the likelihood of the 5.0 crank upgrade being approved?

As a camaro racer I have zero problem with this.

Looks like both you and Daniel (bought Wade's car, broke crank during his first outing at TWS) would be impacted immediately due to having new motor builds pending for 2016.

Yeah, I have everything pending order, I am going to put a junkyard 302 in for TWS then I am going to pull it and hopefully put a solid motor in for next year. My pan is semi trashed too, cam may be in bad shape, my distributor is also ruined. Good game ford, guess the late model 5.0 was really made for trucks.
