Engine Balancing

[Kartman205 0]

Just dropped off the crank,flywheel +clutch cover,front pulleys, pistons and rods for balancing at Autosprint nr Coleshill.

Autosprint have been in the game since god was a lad so know their stuff. They specialise in all aspects of machining (but not crank grinding now, sadly) and are well known in the racing world.

The price, £85 inc vat, bargain.

Pick it all back up next week so I can get started on building the new motor, which brings me to another thing. People ask about the differences between the phases 1, 1.5 and 2 and are told about various trim changes etc but no one seems to mention the differences in the engine blocks ie the extra webbing on the rear of the block making it stronger.

 

PM me if you need contact details.

Your wrong there all 8v & 16v blocks are the same between them from start to finish

Sorry Miles, but I`ve got the two blocks in front of me and on the back ( exhaust side) they are totally different castings. There are extra criss/cross webs between the main vertical ribs.

So how can I be wrong? I guess, like my Motorhome, I`ve got the only one in the country.

 

Looks like I`m gonna have to get the camera out.

you will have one 8v and one 16v block, the way I meant 8 & 16v block's are the same is in themselves not the same between them

Miles, the engine I am rebuilding is an 8v 1.6 GTI out of an original J reg car which itself is the basis for our race car, so how can it be a 16v.

It left the factory like that, could it be that the parts bin was empty when it came to assembling a batch,so they used what was available?

Anyway its a better basis for building a competition engine, has anyone else done this? is it common knowledge?

Had all my bits balanced there also.

I'm not up and running with it yet, however it is all bolted back together now.

Nice bloke isn`t he, an old skool engineer and the workshops like an Aladins cave.

Got to price up all the bits now ie shells,rings ,gaskets etc.

Very common, Most 205 8v Race car's I know have all used the 16v block as all the drilling's are there for the 8v parts but as the blocks look pretty much the same no one notice's or really moan's as there's no power advantage from it, You can even use the later 1.8 Alloy blocks which again are better than the 1.9 16v ones

Thought as much, only the boy racers moan about there being no power advantage, not realising a stronger block is more reliable and capable of coping with the extra power from their dustbin lid valve heads and bucket carburettors
