Q & A

What engine is used in the C15 project?

The project starts with a 1.1L TU gasoline engine block which is combined with a 2L HDi diesel cylinder head to create a 1.9L ethanol engine.

What power did the engine make on the dyno?

On the final dyno run, the engine made 328 hp at 1.4 bar of boost before testing was stopped due to cooling issues.

What was the cause of the cooling issues?

The cooling issues were likely caused by improper connection of the expansion tank, resulting in poor coolant flow.

What drivetrain components failed on the dyno?

Both CV joint boots exploded due to the high speeds reached on the dyno.

What is the next step for the project?

The next steps are to fix the cooling system issues, repair the broken CV boots, change fluids, and attempt to reach the goal of 400 hp.

What engine management system is used?

The engine uses a Megasquirt ECU tuned by Mats for ethanol fuel.

What transmission is installed?

It uses the original Citroen C15 5-speed manual transmission.

What degree camshaft is installed?

A 4 lobe camshaft for increased turbo performance is installed in the 806 cylinder head.

What is the red coolant bottle used for?

The red bottle was used to catch rust flushed from the engine block during testing.

What is the next video likely to cover?

The next video will likely show repairs being done and further dyno testing to reach the 400 hp goal.
