Oh so long since the last update… I assume you’re driving the wheels off it by now?

I thought copper tubing was extremely prone to stress fractures when subject to vibration, doesn’t it go brittle when repeatedly flexed?

Yep, seems to be fixed now, thanks to all concerned!

I’m still getting this error right now…

Yep, definitely worth the money for an SFI-approved bellhousing if you’re gonna be doing things like that… cheap insurance!

Until you guys adopt the National Code Of Practice (NCOP) that is, then you’re screwed!

AFAIK, only SA and NSW are still holding out on using the NCOP, all the other states have already changed over, but then NSW sucks so bad that I sometimes think we’d be better off with the NCOP anyway?

You certainly need at least one port in each head “vented” because the coolant outlet (to the radiator) on all LS engines is down in the block, well below the level of the cylinder heads. If you blocked-off all the steam ports you’d have a massive pocket of air/steam trapped in each head.

And as you say, there are pros & cons to venting all four…[Read more]

It connects all four steam ports in the cylinder heads (which prevents air being trapped in the cooling system).

But good luck convincing Mr Plod of that on the side of the road when he sees “Nitrous Outlet” printed on the manifold!

Very much agree with @gtrboyy, reinforcing the upper arm mounts is an absolute must if you plan on launching the thing hard.

Think of it this way, the lower arms are basically responsible for driving the car forward, but whenever you see a car lift the front wheels off the deck, remember that it’s the top arms doing all that lifting!

The upper…[Read more]

If you have both rear drums fed from a single master cylinder port then you only need one RLPV in that line (somewhere before the T-piece on the diff).

If you have split circuits for each individual wheel then yes, you will need one in each line to the rear drums.

And I’m happy to hear it, but what IS the way around it? I really want to know. Everybody keeps telling me there is a way around it, but whenever I’ve asked an engineer I get the same story, refer to the table.

BTW, vehicle manufacturers don’t have to comply with a COP for “modified vehicles” as their vehicles aren’t modified, but they are…[Read more]

Thanks for that, the weight is taken from the factory figures for the heaviest sedan variant for that model, I asked about weighing my own car but was told no because it’s too easy to add weight and up the capacity.

Even at 1600kgs (x3) that still only allows you a maximum of 4.8L supercharged, so I still can’t work out how he’s able to…[Read more]

G’day all, just joined up especially to ask about this build as we were discussing a similar concept over on the JC forum.

If this car is to be registered in Victoria, which is now under the NCOP, how are you getting around the maximum capacity limits specified in “NCOP3 Section LA Engines”:

Maximum weight for a VS Commodore would be 1477kg…[Read more]
