Have you considered using a large electric motor to drive the system, as opposed to the 1700 cc TIV? Would make the system less complex and easier to manage.

[Jake Raby]

The elctric motor will cost much more to power and will not be able to share the oil system to create such a true climate for the testing... It would take atleast a 30HP 3 phase motor to run this fixture, thats why the TIV is much more feasible. I can build it for 40 bucks- thats the cost of a set of valves and rings. used parts are just 20 feet away.

Good points, but - 30 HP? That much friction to drive the valve train and oil pump? I would have pegged it at around 10 HP or less, and used a 20 HP motor. Regardless, if you have the parts ready, it's a moot point. Looking forward to hearing about results from this setup, hope you feed it back to the suppliers and get them to clean up their acts.

Gene Berg did one for a TI engine.. They started with a 10HP motor and found that it was not enough to get any RPM on the fixture..

Mine is more involved, but much more up to date and covers more bases.
