Hmmm... I thought it would have been a cylinder closer to the TB.

Good job..Going to go with a bigger shot now?

 

[TRicker]

it was just a hyperutectic piston that went, just like i expected. it kinda makes me want to keep with the nitrous, but with direct port. the heads are completely ruined (one anyhow) so i'll probably scrap the two 2.5L motors i have for some $$..... all the heads, and the blocks, etc. hopefully that'll at least cover the core charge on the 3L

 

[todras]

You post pics like you run nitrous.:laugh: Not very well.

 

[KyleQ]

wow man, thats good news - sorta.

 

[TRicker]

ooh sick burn todras well lets start the betting for SZ 08? it's gonna come back strong and nobody will be laughing next year

 

[todras]

LOL! I like your style.

 

[TRicker]

i'll bring a trailer

 

[KyleQ]

lol - I'll be there too, so nobody will be left in the cold.

 

[RawBurt]

LOL, thanks for the text tricker... I was like wtf is this, then I realized and LOL'ed.

If you have any questions along the way with the 3L build, just gimme a call. I want you to get it back up and running w/o any issues. God knows I spent an a$$load of time reading up on my 3L build I might as well share my fresh knowledge.

BTW was't Terry and you talking before you were on dyno about hyper pistons? He told you how they were brittle.

 

[warmonger]

I admire you for posting them up. Now just post up a picture of the piston...and a clear one of the damage...and a good close up of one of the neighboring pistons so we can see whether they have held up well to the nitrous.

 

[RandyCSVT]

Don't forget to save the broken piston so you can throw it at Todras' head!

 

[todras]

Uuuummmm ok.

 

[TRicker]

i know all about hyperutectic pistons, me and terry were just talking about it.

i already scrapped out the block but the piston is one molten blob and a billion ground up pieces of aluminum, the rest of the pistons look like new. there was no pitting on the domes like i thought there would be..... everything seemed tight except the broken piston and the bent rod. sorry i didnt get any closeups.

 

[K99ja04]

That looks very similar to ShogoFast's destruction. Looks like maybe your cylinder pressures were high enough to crack these brittle pistons. Any questions with your 3L give me a call.

 

[TRicker]

yeah i was looking at my dyno sheet more..... and noticing that i got anxious and hit the nitrous about 300 rpm premature to the secondaries opening. i could have had a little mixture puddling on top of the butterflies and when they opened, gave it a jolt of fuel/air/nitrous and backfired a little too hard for the stock piston. i guess it doesnt matter much now

Time to make that MSD ignition a 2 stage? Can you lock out the N20 until a certain RPM?
