I think doing anything to the upper cylinders is very risky. If that is a proven practice by someone making proven power then that is interesting. I would not touch that gap and sure as heck would not take a welder to the top of the cylinders. That's a good way to make things crack.

If you want to use JE pistons then fine, but your pistons melted because of poor engine control, a JE piston would likely have melted, too.

I really hate the comments of "the block/pistons/rods/etc are only good to xxxhp becuase so-and so's broke at yyyhp". It's all utter bull.

BlackBeast did this seam filling mod- I've PM'd him on T5D5 for more info. He's around 450HP (don't know if it's crank or wheel, it's UK measured)

I was assuming from statements of others that the cast pistons don't like constant high revs & may be reaching their limit around 400BHP. I don't have the engine apart yet, so the exact cause is still speculation.

Sticking with your slammed OEM pistons?

No, Trent. I thought I already covered that - I'm using JE forged. The whole reason I'm doing all this is 'cos I melted/broke one of the cast pistons - NOT the one that got slammed, BTW :lol:

You must have these saved already?


Thanks - Mark. I have the '98 wiring manual, but I couldn't find the signal description pages - I just typed them up as an Excel spreadsheet :lol:

No offense- but where do you guys come up with this stuff anyways?

That's from the UK Volvo crowd, as far as I know. I'm not going to go with Darton Sleeves, so filling those seams to prevent potential expansion & cracking has been recommended.
