Wow.

Very impressed with the article. I certainly hope that more research is being done into the failures... I assumed that the SFI had more definitive reasoning behind their specifications, and thought that there was no room for interpretation.

RE: page 14 of Jon's article as printed out...

Tree, Please note the the body that hit the wall on Sunday was not the body used in testing on Monday... I would hazard to guess because of your reasons stated about the body not latching under the photo captioned "Robert Hight is the lone...."

Paul,

I believe what is needed is a driver cocoon/tub which is separate, but part of, the rest of the chassis... with no drive line parts passing through the cocoon, and the cocoon having it's own chute/ air/ fire system riding on top of the main rails... on both FC and TF cars... with that, there will be no temptation for a team to attempt a Topeka...

Thanks for posting the list, Randy. Out of curiosity, is the Paul Sutherland listed the same one who drove for Jim Brissette MANY moons ago?

Fire away, Roo. Please quote the Asher story where the "big holes" are located and then give us the details of the "big holes", your conclusions and your data source to back your findings.

PS. I also asked you to give us your sources for your information a couple weeks ago on my funny car chassis thread and the silence is deafening. I will give you a pass on that for now. Just answer the above.

Please don't give the source for your conclusions like Dr. Metz did in Asher's article by saying something like "because Murf and Dan told me."

Quote from Asher article:

Dr. Metz offers no explanation in his letter as to how he concludes both accidents were the result of tire failures, so we asked him about that.

“That’s what I’ve been told by Dan (Olson) and by the chassis constructor as well. I looked at videos of both of them, and I don’t think there’s any question about Medlen’s. The video I saw of John Force’s accident was a head-on video, so I didn’t get a good look at that, but both Dan Olson and Murf McKinney, who built the chassis, (and) I talked to both of them, and they both said that they thought that accident was initiated by rear tire failure.”

I go to the doctor with a chest pain and my wife comes with me. The doctor comes in the waiting room and we both say we think I had a heart attack. The nurse comes in the waiting room and asks the doctor if he needs assistance. "Get a room ready, I was just told he had a heart attack!"

Don't you think the doctor should at least run a test or two before agreeing with my conclusion. Heck,. I just ate a 32 ounce prime rib the night before and it might just be a bad case of heart burn.

Grant says you may think he is your friend, but he also says you incorrect in your assumptions (that all chassis will break).

Awaiting your response.

Cheers!

RG

Randy...

I have to ask, What's the main Difference between

A N/FC
A TA/FC
and a AA/FC
set of pipes

Beside Engine location...

Keep in mind all the investigative work done was not done to discredit anyone. It was done to find out what went wrong. Are we OK saying it's OK to get killed in a race car? I hope not.

If anyone takes this personally I would suggest you look at what is being said and by who. Why does it seem that there are a couple of people willing to stick their neck out just to be right no matter how blue the sky is, in order to save someone(s) reputation or save a lawsuit.

The reality is...it's about building a safer race car AND SAVING LIVES! Nothing else. If you take it any other way, then you are sadly mistaken.

RG

Plueger's Bucky Austin driven N/FC (one of the most dominant cars right now) is the same as Robert Hight's Black Mustang with regards to pipe. The length and front axle overhang are a little different, but the driver's compartment is the same.

TA/FC. Ron August has my former Plueger car and he has several 5.50's runs under his belt plus a win at the Las Vegas National's last year. It is exactly the same as Hight's black Mustang.

The SFI tag on my Uyehara TA/FC says PRO/PRO SPORTSMAN. It's the same frame.

My involvement in this is? I don't want SFI to tell me I have to run a heat treated frame and take a chance of killing my driver.

RG

Randy, very well put...
I'm hoping that no one is trying to throw any one "under the bus"...
And NO, it is NEVER OK for anyone to be killed...

Nor is it okay if a mfg has a solution for issues and is told "we can't because we'll have to throw are stuff away and start from scratch" see ::: Drag Racing Online ::: Part 2: Tire issues in the nitro classes are still a major problem - 10/10/2007

maybe it is time to start with a clean sheet of paper... listen to what has worked, listen to what can be done, and re-invent Floppers and Rails...

Question Everything... is there a reason Rails must be 300", is there a reason floppers must be 125"... any more than they must be 116" or 120" or that rails ideally should be the circumference of the tire?

I see a problem in the rules that except for the body, all cars must be identical... there is no wiggle room... gear spec'd, engine spec'd, tire spec'd, body must be approved, which I find funny, floppers today look more like what's on the street than they did 20 years ago, even ten... go back to the max chop of 2", min width of 66", max spoiler heights, ect.... wheelbase +/- 10% oem? I hope not...

and there in lies the problem... we've over spec'd the unimportant stuff, limiting innovation... and ignored the safety stuff

You said this earlier:
Randy asked Grant about this and Grant said he's never had a tube fail. So which is it, does he have his head in his rear (your words) or are you calling him a liar? Or could it possibly be that he just hasn't had a failure and you just don't want to believe it.

"I got a fever, and the only prescription... is more cowbell!"

Buell's and Hardley's suck!

Grant specifically said from the front motor plate to the back of the drivers compartment. I didn't ask him about the body tree off the rear of the cage. Those are the small tubes that support the back of the body and the puke tank.

"Never" were his exact words.

Mats Erickson from Europe, listed as a "No Response" has responded.

He said to be sure to let the American's know he falls within in the middle group of "normalized" chassis builders and not the heat treated group.

RG

When I visited with Bernie shortly after Eric's accident, I asked him if they video taped the run. He said the camera malfunctioned and there was no tape from that run.

So how did this guy evaluate Eric's run if there is no recorded version of it? And he's only seen the front view of John's crash? Uh? We've all seen it from both the front and side angles.

I got a PM from someone who wanted to know this:

That's the same "guy" who refers to Murf as "the chassis constructor." Like, he barely knows him? And he's on RETAINER to the guy?

What I've been surprised by thus far is that no one seems to be mentioning that fact -- that the sanctioning bodies sole piece of supportive information came from a paid consultant to "the chassis constructor."

What do you suppose he meant by that?

RG

okay, next dumb question...

I know we've been doing it for the last 30 years or so...
what's the effect of running hot nitro/alky/oil through the top rail to the puke tank? Could an ignition/spark cause an unknown fire in the rail?
