First to modify the venerable LS with VVT, and the first to rebuild to maximise the benefits from the combustion properties of ethanol.

Looks great, same place I was thinking.
What did you use exactly, Accusump 3 litre?
What pressure solenoid (I take it is not manual)?
Also what paint thanks?

The hydraulics are a priority on this particular build as it runs high lift AFM collapsible lifters and Oil Control Valve for the Cam Phaser, which dictates critical oil supply.
Also addresses the seemingly typical under-lubrication of the camshaft face and bearings in these engines.

Yeah thats what I was thinking, good value, common sense improvement with no downside, except three litres more oil at change.

Yeah Accusump or Moroso, have an inkling pre-oiling the engine, particularly pressurising the lifters, cam and valvetrain on startup will prove worthwhile insurance.
Seems the weakest link in Gen IV at least is the cam/roller torque friction under 1900rpm.
Looking at three litre 35psi remote solenoid wired to ignition, plumbed at the bypass.

Anyone had or is currently running an oil accumulator on their LS?

I use these for my hillclimb car. They are impressively sticky even when cold…

Holden that doesn’t have VVT or pump at least 12:1 static should

pir4te replied to the topic Un-throttling a V8 TTurbo with AFM in the forum Engine 9 years, 6 months ago
Stock L77 cam is actually really good, the key is using valve events as per Miller Cycle.
To achieve this you require more scope / flexibility in your valve timing using a cam phaser, like I have.
450rwkw out of a twin turbo 6.0 V8 is a known thing, scaling back your effective volume to a highly efficient 3.0 on AFM and from around 4.0 on…[Read more]
