I would like to sit down and work simulate the maths at what point this could happen at, but I'd rather spend time researching components and good stuff and just make sure I don't get that recipe. e85 will pre-ignite if you have the right hot spots and too rich conditions can also cause some bad results for e85. 17 hours ago, Puffwagon said: No I didn't mean that man. Fwiw you seem to be picking it up and understanding it rather impressively. Yeah definetly learnt a stupid lesson I won't repeat. I had also been using and tuning the wastegate all day and it turned out it had a leaking diaphragm and oring. This compounded the problem. So second lesson is triple check used parts before trusting them. Link to comment Share on other sites More sharing options...

My understanding is lpg ba. 10.7:1 lpg bf-fg 10.3:1 lpg fg mk2 + 12.0:1 I was standing in a a wrecker at Tuggerah ready to load up an egas to a trailer but it was so rusty and covered in oil I didn't want to part with my $500 for it in the end so pulled the pin at the last minute. I don't think there are anyone making forged pistons from 2618 steel over 9.0:1 for the bars? But I have to admit I didn't search too far for the softer composition pistons.

That'll be cheaper albeit more time consuming than using a wrecker donk. I haven't checked to see if it would work but it might. Link to comment Share on other sites More sharing options...
