Pics of my old valve

[red17]

Heres a couple of pics of the damage done to one of my valves a couple of months ago after a night out at the drags turned pear shaped.

I have my doubts about all of this damage being done on the night in question, in fact i think it was low in compression on cylinder 6 when it came off the boat in September. I just made it much worse when an electrode broke off a plug and went through the valve. :eek:

In all only 2 valves required replacing at a cost of 55 bucks each. Not too shabby. But it could have been MUCH worse.

This was when running 0.8 bar on a stock cooler on a relatively cool October night.

Mayhem,

Id only had the car 2 weeks before this happened, ran it a few times on 0.8 bar before i went down the strip without problems. My own stupid fault i suppose. But it goes better now than it ever did so I figure some of the damage on that valve was done before me.
