I made my first pass yesterday for a tune up pass and went 175 mph for the mile, and went 174.4 in the 2 1/4. Just shy of making the long course... That was in 5th gear, We turned up the boost and getting ready to make another pass in a few hours.

Jon,

Thanks for the updates.

I heard there was no line for the long course and the short course line seemed like it was a mile long shocked

Just a WAG,but I am guessing you dropped one valve/valve head and that instantly started hammering the crap out of the rest.Look how you can see the other valves bent back in-----just one man's opinion.
And BTW, it totally sucks it had to happen, I can truly relate,bud.

Oops,the last pic just loaded and you can see the valve head.Just a parts failure--

Jon,

Can you post a close up picture of the other three pistons from the top, I know this was the same pistons you ran before however it appears that the pistons may be hitting the head at TDC, what is the piston to head clearance when you assembled the engine??  You should have about .034"-.040" with your RPM, HP, and piston speed.

Jon,
  You'll probably get all kinds of WAG's why your engine came apart! Here's mine:
  It looks like the same as an old 912 Porsche engine I had that had a intake valve seat come out. It too made a hell of a mess. Any other seats that show cracks around the seats?
  Good luck on finding another engine! It sounded like you were on the right track with your set-up.

Well as many off you know I went to BUB speed trials and had some success, some smoke, some fun, one record...

We started the week off with a mild tune up and 7 lbs of boost. THis netted me two runs 188 and 191 mph.

During the second attempt I lost communication with the brand new Haltech E11 EFI unit. The communications port failed within the unit.

We shimmed up the wastegate and turned up the fuel pressure. This is where it get exciting, during this run I was on a 215+ run (data only) when an oil line burned thru by the exhaust and just drenched me in oil. Let off a spectacular smoke screen in the process.

Took the bike back to pits got it semi cleaned up and found an oil line behind the header burned thru. The face of line was cinched thru. We repaired the line and added fire sleeve to the line.

Next run bike seemed to pull but wasn't as strong as the other runs. Made a couple more runs and progressively the boost was getting less.

Put it on the trailer and got the about 190 record certified for the AMA MPS-BF class 650cc.

Brought the bike back to denver and my crew chief and I were baffled on why we were loosing boost. Could it have been because when the oil pumped out during the third run and starved the motor for oil. (when that was said and done there was a 1 qt of oil left), could the turbo be going away, is there a plenum leak somwhere??? We were down on compression a little but not enough to worry about.

Here is what I found below and this explains everything that happened during the week. Explains the oil line, loss of power, and why I couldn't build boost every run it got worse. Repair has been made and now looking to add some more reinforcement.

We will be back for World of Speed in a few days...

Are you and your Haltech on speaking terms again?

Had an oil line break on my 600 turbo also. Though the motor was toast,but pulled it out and apart to find it was unhurt.Had fuel fill a cylinder and it would not crank over.Whew!!
Good luck,Jon.Want to see BIG numbers!!

Well Yes Fireman got Haltech unit back Saturday...

We got the engine fired Sunday night, it runs once again..

Here are the pictures of how we fixed the problem and secured the turbo header. Should be less prone to cracking and now held in position properly..

We leave for WOS Monday Night around 10 pm.

Jon,
I am sure that someplace in this 8 page post you mention what material you made the headers from but I am going to ask anyhow. What is the material? Stainless?  What is the tubing thickness? From looking at your pics of the failure it appears that they may be steel. Your added heat sheild appears to be stailess but the "repair patch" appears to be steel.

Typically for turbo headers the peferred tubing material is 321 stainless and I would think that 14 gage (.071 thick) would also be the minimum. I worked on a tubo Chevy V6 that we ran at Daytona and we had to make the collector section from Inconel 625 to get it to live. Somewhat similar conditions to running at B'ville, once we came out of the infield the engine was pretty much ran at WFO and max boost for around 1-1/2 miles on the high bank. (this was in 1983 and the "bus stop" chicane was not built yet).

Just wondering.
