Is It True.....
That the moulds in a car manufacture factory get worn out so techicaly a late Mk2 Vtr will be up on Bhp marginaly on a early mk2 vtr as the moulds have worn out to different tolerences?
someone told me the other day and just wondering?

might have done but I wouldnt think they would make much difference
or that could be why vtrs can get to 60 in second?

No two engines are exactly the same imo - too many variables involved in the manufacturing process.

You mean casting moulds on the heads? Depends if they are sand cast or not.

There probably is some truth in it, but any difference is going to be negligable.

Each mould is destroyed after sand casting though so will all be the same unless you got a monkey making the cope/drag and cores

There are certainly differences in heads. We find that when customers come to fit cat cams 708 or Newman ph3 cams they ring up saying the camshafts catch on the head. Most are fine, but there are certainly visible tollerance differences.

they may be cast a different sizes, but the bores will still have to be machined to the same size.

No two engines are ever the same, however power differences will be superficial when new. I'm involved quite alot in manufacturing parts for the new Bentley Mulsanne's 6.75 V8 engine, they produce 505bhp and 1020Nm of torque. All are Dyno'd to ensure they meet that specification, a tolerence that sticks in my mind in +/- 3bhp. I can imagen citroens quality control for the saxo is somewhat less strict however it would be impossible to distinguish if power differences are manufacturing caused or just down to how the engines been looked after over time.

Random question but anyone heard of a Saxo vts tour de corse?? And this being 170bhp standard. What has been done to the engine to make it 170 instead of 120 as normal??

Wasn't 170, if you see the spec of one. It was a dealer special with LAD.

In the case of cliosport's it is. Their inlets are miss matched to the block so most people get them cnc'd check the pics in this link

this is true, thats why blocks have different colours for shells and cranks,
black, blue, or green. all standard sizes nt repair, represented by a letter on the block and crank to depict what size needed.
