geek email me your account detail is there more to the artical

 

Is that pin support method a tried and tested technique? I would have thought that with the cylinder walls expanding outwards and the pin's dia increasing as it expands it would impart a point load and hence a corresponding deformation onto the cylinder wall? At least with a deck plate the plate contacts the entire circumference of the cylinder so any expansion loads imparted are equially distributed around its circumference. Also with the pin lengthening due to expansion would it impart an upwards force onto the underside of the cylinder head and HG?

 

The pin is a tested technique within the Subaru boxer engine crowd. Those engines also have open deck.

 

I'm a member but I don't see anything about the engine or turbo in that article?

Yes you're right, it was "Zoom"-magazine. But the article wasn't about Zorans car. I'll dig out the article right away.

 

Correction! The magazine is called "Race" - "Race Performance, Car Constructor Magazine."
"Australia's Most Technical Motorsport Magazine".

This was issue .01 Feb-Apr 2005.

I'll dig out the scanner..

You know you love me!

 

Wonder if that's one of the Fitzgerald Racing ones?

 

well it looks buy the extra counterweight relief under the pistons it was a shortened rod build so it's looking a bit like the Zoran bobile so the ****ty block was buckled six ways to sunday and coolant flow and dowls were looked at .
tragic how much seems to done to try and get these things to hang together makes be shy about the stroker crank idea

 

concerning the peg did you hone the cylinder after you put the pegs in? I am just concerned that the press fit would distort the cylinder slightly. Maybe im being paranoid lol but im thinking about doing this for a spare motor im gonna build

 

yeh bored and honed after the peg other wise measure carfully befor and after

 

I'd be concerned about expansion rates as stated before. I guess what looks like a really cheap fix could wind up costing more than the deckplate by the time you sort it out.

 

At what point would you say a deckplate / peg would be called for? As far as power, boost, etc. I'm about to build a 3.0L 8v turbo and I'm shooting for about 325hp at the crank.

 

yeh keep telling yourself that while you bleed hundred dollar bill's and ship them to the US
far more expansion rate trouble comes with dissimilar materials .
I've just seen a failure of the concept in that article and it still wasn't that expensive .

 

325 is lazy as but i herd from this chain of events that led to those fitpatrick motor biulds that 350 engine house power this seems to be disproved here i rennlst . but i don't know how lond they stay together
i would say 400 at the crank.
