Competition I Think He Has a Boost Leak Now

You've got to go check out these pictures, quite a site from a recent NY tractor pull.



Whoooops

I don't think I have ever been able to see carnage like that at a tractor pull.

Looks like he pulled teh complete cylinder head right off. Must be using NON-ARP head studs,, tsk, tsk.

Whats the name on the side of the tractor... circumcision? :-laf



Seriously though, I dont think ARP head bolts would have kept that thing together. Wow, what carnage!! Was the guy ok?

 

[lil red cummins]

funny you should mention that, i went back to the pic and it looks like it says "satisfaction". i would imagine after that run, it is anything BUT that. :-laf



i don't believe that is just the cylinder head we see. it looks like the block split between the crank and cylinders. 2 piece block - what an interesting concept.



anybody know what kinda power, boost, rpms that engine was putting out?

The driver was fine, just a little soiled :-laf He was suppose to have it back together for last weekends pull but he wasn't at the early one. I'm not sure of the exact specs of these things, someone like Gonzo1066 (I think) could tell us more, I know some have one charger and some have three, they use water injection and shoot smoke way up in the air. I've heard numbers of 150-200 psi of boost and 5-6,000 rpm but some of the tractors run on alcohol so those might be the ones running 6,000 rpm.

Man and I get bummed when a head gasket goes

Dayum!!



I bet most of the crowd soiled themselves when that happened... :--)



That's an expensive hook, my friends.

Was probably diesel powered. Usually alcohol tractors dont run near as much boost, so therefore catastrophic failures like this arent as common. This type of failure is not to uncommon in the super stock (multiple turbo) classes. They usually beef up the bottom, and top end, but the week spot is the block. Most of these tractors have had severely oversized liners put in, and the blocks have been machined out pretty thin.

Heres a link to another pulling catastrophe. http://www.rossagri.com/hoe_handle.htm

Check out the billet cylinder head and the nifty cylinder head 'turnbuckles' on "Hoe Handle"... now I know how they keep the head where it needs to be. As you can see - they found the next weak part, though.

Matt,

Yea the team I'm on our 3 big tractor we use cable over the heads like that. just incase something like that should happen. by looking at the tractor in the picture its running 4 turbo's capable of 250 psi max. and if you were to take a close look when the head is off. The sleves are machined flat on the side so they go together, and when your runing about a gallon or two of fuel and water in a 15 second pass there is plenty of room for failure like that.



oh you were woundering the specs on something like that? around 1000+ ph trq your geuss is as good as mine.

O. k. This may be a little redneck but why don't these guys fill the block with concrete?

I've seen more than one 1/4 mile pass in the 10 e. t. range with a "high solids" 454 chevy. Any good reason why it can't be implemented here?

 

[lmills]

I'm not sure really what good filling the block with crete would do in this situation. Most drag racers do it to stabilize the block and to strengthen the sleeves. In this situation the block split down the sides, along the oil pan rails and seperated. The top half lifted off the bottom half. So filling crete around the sides of the block it still could have happened

I haven't gotten to play with any engines like that so i didn't know the exact nature of the failure. Thanks for the reply.
