Twin Turbo Rebuild Part Something Or Other...

277 posts in this topic

As posted a while back, lost my aluminum motor at ~210mph running the Texas Mile in March when the Manley intake valve that was supplied with the built Thitek heads came apart in hole #3.  The valve head separated from the stem, took out the Mahle 2618 piston, wrist pin went free and then the 300M rod tore the hole/block, eventually twist/snapping on the iron sleeve.  Pricey valve failure but shit happens when you race and I managed to walk away thanks to the DJ Safety engine diaper and the StopTech brakes that somehow helped me stop the car despite being completely oiled.

 

The car was shipped to A.J. at Hemiturner Performance in NY, and arrived in April.  A.J. pulled the heads, motor, converter and transmission and the turbo kit.  He will be handling the cleanup of the mess, the rebuild, and will once again be tuning the car.  

 

Deposit was paid for a new aluminum motor from Chris Seidle of Seidle Racing Engines end of April. Chris indicated the parts are to arrive this week (pistons and rods).  Assembly should be another 1-2 weeks out after the parts are in according to Chris.

 

The heads went back to Craig at Thitek several weeks ago.  He has gone through them and identified some issues.  Craig asked about some of the short block parts such as rod bearings in an attempt to better understand the failure, and I've provided full access to A.J. as the damaged short block is in NY. Craig will have the DS head repaired, both heads will be remachined and rebuilt using parts specified by Chris Seidle.  Craig was to order the parts today.  Heads are couple of weeks out I'm told. Main focus is to avoid any drama on the rebuild so some changes are being made.

 

A turbo kit was ordered from Jason (aka "rollbar") of AGP several weeks ago.  Deposit has been paid and he told me today it is a couple of weeks out.

 

Nothing but Frank's (Driveshaft Shop) parts in my car.  9", aluminum driveshaft and half shafts....all DSS and zero breakage over several events.  

 

ProTorque will go through the converter to make sure it's good.  A.J. is to drop it off.

 

The transmission is with Rossler.  They are to go through it in the next couple of weeks to make sure it's good. 

 

Precision called and is going through the turbos now.

 

We will see when the parts show up and when the big girl will be back together.  I will post updates when there is something to report.

Get R Done Sammy.... Sounds like you have your shit lined up and you should have another record run waiting to happen, especially with AJ in the co-pilots seat.

 

AJ FTW again!!!

Good stuff Sam.  Fingers crossed for quick time lines and smooth sailing.  I'm really digging that AGP TT setup.  Looks like a nice piece.

Sounds like a great plan Sam  Great choice on a engine builder.  Seems more and more folks are seeing the light  Chris builds a great engine.  He built mine in 2009 Ive sold it since "Still running btw"    Best of luck bud

The crew and the plan sounds great, hopefully everyone comes through, I'm here if you need anything Bro.

 

Seeing the damage first hand that the head of that Manley 2.16 valve did is amazing ! Seeing the manner in which the valve failed does not give me a warm & fuzzy feeling about using them in my new build.

Thanks to All for the support!  I'm hopeful we can get the big gal up and running before too long, and I can get back out there.

 

Lisa - definitely a new DJ Safety diaper and replacement front StopTech rotors will be coming.  I asked A.J. to inspect the rears as I was only able to look at the outer sides of the rotors when I had the car in the garage.

 

Kenny - no Manleys going in the heads this time.  As a matter of fact, no Manley anything.  Had my fair share of that lovin'...

Reading about that motor is pure porn! Your going to need warning signs on it not to get to close or get bitten or worse. Got to see that beast when finished

The important thing is that you got that car stopped safely.  At that speed, shit happens real fast and things can go sideways real quick.  Glad you're OK man.

Thanks.  I was fortunate.  Car pulled hard left when I braked and wasn't slowing down much....the PS rotor/caliper were oiled more the the DS.  Fortunately, got most the oil burned off while largely maintaining a straight line.

 

Scott - didn't look like it but the head of the manley was beat to hell by the Mahle piston.  Just looks like it broke off right at the top of the stem....part failure based on what we saw and what A.J. saw during disassembly.  Pics are posted in the TX Mile thread and I think I started a separate one on the failure.  Craig has been in contact with Manley.  I see no relief coming my way from anyone, but I'm making the parts available if needed.  Lost motor and all the repairs are on my dime.

This is a pic I took in the pit, if you closely you can see the end of the intake valve stem with the head missing. Stem doesn't look bent at all, like the head just snapped off the stem.
