Not sure if any of you really recall, but back in December 07 I had recently purchased this truck and had a valve break causeing a complete loss of the engine from head to oil pan including the turbo. This included the turbo.
It was replaced under warranty since a valve broke at the lazer weld seam and dropped into a cylinder.
Last Saturday I blew this new engine.... bad. Yes, it was my fault. No I did not take it to a dealer.
I am running mega timing and fuel without a turbo.... shame on me!
I am running Scary Larry (Triple Dog) with a Quadzilla X2 race module (Pressure only program), AFE stage 2, Straight piped 4" exhaust, CFM+ Intake horn, and Snow Perf Stage 2 Water Meth.
I was at a sled pull on Saturday and I was pulling low range 2nd gear at 2800 RPM with the EGT's at about 1335 on the Commander. When I was red flagged at the full pull (About 320 feet out) I lifted the throttle and the engine shut down and stalled IMMEDIATELY. I went to re-start it and the engine barely turned. It began to slowly crank, and finally started. It was spewing white/blue smoke.... My heart stopped beating as I looked into my mirror at the exhaust turn up... I hit the throttle to try to clean it out since it was smoking terrible and shaking hard..and the smoke went instantly to pure black bellowing soot. O.O!!! Now my heart actually stops!!!
I drop it into gear and head straight to my trailer and slam it on. I turn it off and notice oil dripping from the crank case breather tube under the engine. Not cool.
I go straight back to the shop and call Rick Chovan and Justin Sciulli over to assist in drinking my beer and pulling the head. After a few hours of beer and wrenching we have the head on the bench and we are all setting around with tears in our eyes... and beers in our hands... looking at a hole blown thru a valve in #2, and piston #3 and piston #4 melted bad and cylinders 3/4 destroyed and blue from heat.
So, out comes the not so mighty Cummins.... for a couple sleeves, a set of Ross pistons, a Twisted/Crane cam, ported head, 110 lb springs, titanium retainers and 7° locks. Also.... this time its gonna be with a Industrial manifold and Silver Bullet... and at least for a while the Boost Juice is gone and will be replaced with straight water. I think I'm going to throw the Bully Dog in the trash and go with the Smarty TNT 4K tune.
So, I just wanted to let you all know... that when you think about tuning to the hilt... you better thing about a TURBO!!! That stock HX35 does not have the ability to cool a balls-out tune on stock sticks... let alone a set of performance sticks with big tunes! Be wary.... take note of my repeated losses... and learn from my mistakes!
I always hear that you better be tough if your gonna be dumb. I guess I'm tough?
