Post anything related to this topic in here
Has anyone done this in Aus yet?
anyone got any hard figures, dyno graphs, spool up time etc
some pics and info for people that have nfi wat im on about
"A compound turbocharger system for an engine/compressor unit is disclosed including a pair of conventional turbochargers including turbine components connected in series to convert exhaust gas energy from the engine cylinders into mechanical energy for driving a pair of impeller-type compressor components arranged to supply sufficient quantities of air to the intake manifold of the engine cylinders and to the intake manifold of the compressor cylinders. In one embodiment, the impeller-type compressor components are arranged in parallel. In a second embodiment, the impeller-type compressor components are arranged in series with the air supplied to the intake manifold of the engine cylinders being provided by the first compressor component. Smooth operation of the engine/compressor unit including substantial self-proportioning of the air boost to both the engine cylinders and compressor cylinders is assured by means of a compressor cylinder control means and engine throttle means for adjusting total compressed air output and engine rpm to the compressed air being utilized by enabling or disabling compressor cylinders one at a time in succession and by correspondingly adjusting the fuel flow to the engine cylinders. A compound turbocharger system is also disclosed for supplying compressed air to an air pressure operated conveyor."
Suitable for attaing high pressures, which are absolutley useless on a Gas(Petrol) engine.
That setup you posted is for a performance diesel engine.
Diesel engines actually run via detonation, so you cant actualy destroy them like a gas engine.
yer it originated from diesel engines but like R34NRG said there has been alot of r&d regarding this and the yanks actually have an off the shelf kit for 2jz's i beleive
costs $6900us so its in no way cheap but they are reported to have 20psi@2800rpm and by then the bigger huffer kicks in and keeps hauling all the way to redline
Some original photos have not been recovered yet.
U couldnt fit anything thats gonna work better than a properly selected single turbo under your hood anyway.
A lot of the tractor pull guys use a compound turbocharger setup.
the 2jz boys seem to do alright from it

anyone thats interested watch the first 6 videos of this playlist
wow, turbocharging a turbocharger, wtf. It seems abit unrealistic to be pushing hot air into a allready hot turbo charger. Fair enough for diesel applications but for a petrol engine your probably better off having a larger turbo with a good intercooler setup anyway.
i think its more so how the power is delivered
u might have a single turbo gt42 vs a compound turbo setup with a gt35 and gt42 (which is similar to wat that marc guy is running in the vids) and where the 42 might see nothing until fullboost at 5k then its all over the road the compound setup will be around 4ish and deliver a smooth powerband
id love to give one of these setups a go through an auto

High pressure uselss on a petrol motor? The piston don't get moving by themselves. The quickest cars run huge boost, and not just for the conversation factor.
You can destroy a diesel motor. They're not invincible.

cant see there being much of a difference
Me too, I'd like to see some evidence(video footage) of a drag between a single turbo charger setup and a compound turbo charger setup, or some figures using the same turbo charger. (ie one GT42 agaist a gt35 & gt42).
