Thread: DET failure

i am curious, from all of you that have had your stock DETs go kaboom,

what did it?



was it the piston that failed or the head that lifted,...

anyone with a w11 that failed?

very interested to know. **dont say it leaned out. im looking for what what PSI you were pushing and what happened.


*Reason behind it, is i was thinking about putting pistons and rods in my det alongside a vet oil pump and vet head along with 1/2" mazworx head studs. BUT........

right now i want to see if i can hit 500+ on stock block, c16+meth. i understand it will be a bomb waiting to happen
BUT i dont want a ticking time bomb that has a very short fuse, maybe a moderate fuse lol.

if i can get maybe 20 passes at the track ill be happy. * i dont drive the car every day

WHY?

because i dont feel like spending more money on my car just yet, im looking to purchase a house. ill do a build later

no one?

I've always upgraded just because. Never because of a failure. I have seen rods come out, but not really any piston damage. Hmmmmm. I have a RR motor here which apparently the owner never changed the oil. It spun a rod bearing.

It will hold for a while without probs if you tuned right...

Im thinking of going 9.1CR and VVL oil pump in my DET

Detonation is what eats motors... the sudden impact puts very high instantaneous loads on the internals which eats em.

So as long as you don't detonate or run hot everything should hold up somewhat.... You are still be exceeding designed loads, but there are safety factors that you can eat through.

you can always build it

what did you have in your setup if you dont mind me asking.

This looks like it will be more fun

hrrrm, well then we shall have to see how we can lessen the chances of detonation. i would like to see if i can get the car into the 10's before it blows sky high!
