Merc for Stone Brothers Racing

They'll have to catch up first. When the German engineers saw SBR power figures they basically called it as bullshit. They didn't believe a 2 valve engine could be making 640hp and 480lb/ft

I hope this story is true, definitely a Straya cunt moment

"Mrs Klimenko is the property developer daughter of Hungarian immigrant John Saunders who co-founded Westfield with Frank Lowy.

With her eye-catching blast of blonde hair with pink highlights (this week), bold and obvious body art and a preference for making an all-black fashion statement, Mrs Klimenko doesn’t fit the usual stereotype of a race team principal or perhaps even a Mercedes-Benz owner. But she’ll match or better bank accounts with most along pit lane and is reportedly ready and able to throw money at achieving her goals in Australia’s most popular motor sport category."

I've been wondering who Erebus were and where they came from.

(on a side note, I think Lowy is as shifty as they come - his name, and the rest of his family, was all over the Lichtenstein banking scandal a few years ago, and it was hushed up VERY quickly in the Australian media)

Par for the course of being a rich cunt, all the high net worth people are up to shit like that..

That engine cover is fucking made for a badge engineer job.. Honestly this is retarded.

It is quite possibly true. A highly respected drag racing cylinder head guru from the states (so he is a v8, 2valve type of guy) was shown some flow sheets and a dyno graph of one of the HMS supercar engines and said it was not possible to be making the numbers based on the engine size/rpm/head flow.

Don't they just use nascar stuff these days? Or is it all done here?

gmh265, who was it?

All of it and none of it is Nascar in a way.

Ford blocks are a Motorsport item you can buy, probably for a lot less than a service on your C63 Benz, at $1600.
Heads are 'D3' and supplied by Ford Motorsport as a semi finished casting that is also used in Nascar and Comp Eliminator drag racing. They are machined and expertly finished to a maximum port height and relatively small inlet valve size (2.125") for Aussie V8's
Rods are minimum weight transparency items from various vendors and pistons are the same. Cranks come from Bryant and others and are also regulated for weight and journal minimum diameter. The rest of the gear is pretty straightforward. You could go out and order everything you need, probably off the shelf for a Windsor. The HMS/GM engine is a direct Windsor copy but not an interchange and not quite so easy to get stuff for.

With a few more freedoms to reduce friction- 'our' 7 mm valve stems and 2.25" crank journals are big (6 litre Nascars use 2" mains, 6 mm stems) and the reciprocating parts are quite heavy- I have a souvenir Ford Carrillo rod that is no longer legal, that weighs a bit over 400 grams- and porting/valves/cams, but not an increase in RPM, they would probably be up around 680 hp.

From the Book:

7.3.10 The minimum deck height of all Ford and Holden Motorsport Cylinder blocks is
207.0mm. It is permitted to use components that do not comply with this dimension
during Rides and Testing only.
7.3.11 The camshaft lifter bores must remain in the same location as specified by the
manufacturer and the samples held by V8 Supercars on the Ford M 6010 Boss 302
and the Holden Motor Sport 22534350 cylinder blocks.
7.3.12 Cylinder Block Weight
7.3.12.1 The Minimum weight of any cylinder block used in the VCS will be 70 kg.
The weight of the block will include any Core/oil gallery and Rear Cam
tunnel plugs Cam Bearings and any internal oil feed or scavenge lines
and removable rear main seal carrier.
© V8 Supercars – 2012 Division “C” 1st UPDATE Page C25
7.3.12.2 A block that is less than 70kg is permitted to have ballast weight to bring it
up to 70kg placed on either:
(a) on the Chassis rail no further rearward than X+ 1855, no lower than
the underside of the front Chassis rail and must not protrude more than
25mm from the inner face of the Front Chassis rail and be equally
distributed side to side of the vehicle; or
(b) on the block itself in a position approved by the CTM that does not
lower the centre of gravity of the block.
7.3.12.3 The maximum relative density of any material used as ballast is twelve
(12).
C7.4 Cylinder Head
Subject to the Rules contained in Division C and the dimensions contained in the relevant
VSD.
7.4.1 Modifications to the cylinder head are free, save for the following:
7.4.2 It is permitted to add material to the cylinder head provided that the integrity of the
original casting is respected and that no attempt is made to vary the basic design of
the approved component beyond the permitted modifications and that it must
always be possible for the cylinder head to be identified as the approved part.
7.4.3 The original spark plug location must be retained in all respects.
7.4.4 It is permitted to use valves, valve spring retainers and collets manufactured from
Titanium alloy.
7.4.5 Valves must only be opened by mechanical action and closed by means of coil
springs.
7.4.6 For all Ford, and Holden Motor Sport engines, the maximum inlet valve diameter is
53.97mm (2.125 inches).
7.4.7 The minimum inlet and exhaust valve stem diameter is 7.0mm
7.4.8 The inlet and exhaust valve heads and stems must be solid.
7.4.9 Cylinder Head Weight
7.4.9.1 The Minimum weight of any plain bare Cylinder Head used in the VCS
will be 13.5 kg. The weight of the head will include valve seats, valve
guides and rocker cover studs.
7.4.9.2 A head that is less than 13.5kg is permitted to have ballast weight to bring
it up to 13.5kg placed at the rear of that head attached by bolts or studs.
7.4.9.3 The maximum relative density of any material used as ballast is twelve
(12).
C7.5 Pistons
7.5.1 No part of the piston may protrude beyond the cylinder head face of the cylinder
block when the piston is at TDC.
7.5.2 The minimum weight of each piston including the piston pin, but not including the
piston rings or retainers is 500 grams.
C7.6 Connecting Rods
7.6.1 Connecting rods must only be made of Ferrous Material.
7.6.2 The minimum weight of each connecting rod including the connecting rod bolts, nuts
and washers but not including the ‘big end’ bearings is 500 grams.
C7.7 Crankshaft
7.7.1 The crankshaft must respect the approved crankpin phasing and throw angles as
detailed in the relevant VSD.
7.7.2 The stroke of the crankshaft must be a maximum of 77.22 mm and a minimum of
75.18mm.
7.7.3 The minimum crankshaft ‘big end’ journal diameter is 47.45 mm.

A lot of parts are sourced from the US (block/crank/pistons/rods/head castings/valves/rockers) ok, most of the parts, but they are obviously spec'ced to the teams requirements. Nascar has also played its part in making the V8SC engine what it is as well.

Most of the cylinder head development/intake manifold/machining/packaging stuff is done here.

greenhj, not really interested in putting any more info on that up on the net sorry..

Edit: Momus beat me by a fly shit with heaps more words..

[Billzilla]

They do some really tricky stuff, like I heard that when they flow the heads they don't use suction, but pressure instead. Lots and lots of pressure (60" or about 30 psi or 2 bar) to make sure they get every last bit out of them.

Do you mean when testing exhaust flow? I have not seen it being used this way on the inlets.

That's the way I understood it, I may have heard it incorrectly though.

[gmh265]

I did not think that blowing out the exhaust was uncommon, so I assumed you were talking about something even more funky.

This bad boy here can do it up to 65" of test pressure and can talk to performance trends logging software as you test. http://www.superflow.com/Flowbenches/sf1020.php

What's the bizarre weight rule about? Take everything you want off the block and replace it down low on the chassis? Seems like the exact thing you would want to have happen and make you inclined to spend a fortune hollowing out blocks?

Am I missing something?

Your missing that the position they allow you to bolt weight on is a worse place for CoG and also polar moment. back in the earlier days (pre 07 i think) you could cut what you wanted off the blocks, so they had to make it possible to weight up the older lightweight blocks when they brought this rule in.
