It’s a long-awaited episode of Carnage this week, as our ‘Supermang’ VN Berlina – with its troublesome, supercharged 4.2-litre stroker L67 finally sitting pretty up front – hits the hub dyno to see if all the headaches were worth it.

In recent weeks, Scotty has been battling the stroker engine at every turn to get it to work. First, a clearance issue with the rotating assembly required a new and smaller Crow Cams camshaft that would play nice with the Mahle pistons and H-beam rods.

Then, once the engine was back in the car, Scotty found it had no oil pressure at all. That meant the mill had to be pulled out again to get to the bottom of things. Scotty soon discovered the culprit: an incorrectly installed oil pressure relief valve. Luckily, no major damage had been done.

Now, at long last, the engine is back in the car and working. As well as a smaller camshaft compared to the one in the old 3.8-litre L67, Scotty has also ditched the water-to-air intercooler and gone with a larger top pulley.

The lack of intercooler will simplify the set-up for eventual street use, while the smaller pulley we were previously running wasn’t working efficiently for the M90 blower. Spinning it faster just created more heat with less power, so the larger item should fix that for the stroker engine.

Scotty had hopes of making 300rwhp from the new mill, and while you’ll have to watch the episode to find out the final power figure, we will tell you it made north of 700Nm of torque at the hubs!

Peep the new episode below, and let us know if you think the extra 400 cubes of capacity was worth all the effort.
