Super cool 1965 Morgan road race car in for some diagnostics and pulls! Just a tiny Ford 1.6L 4 cylinder setup, but for what it is, it is very much still like a big go-kart!

The '16 CTS V3 made some good numbers! This was a baseline to confirm some quirks and make sure the car is healthy enough for more mods! The numbers ended up arond 537whp and 608wtq. This car needs a set of injectors, seen by some slight missing up top, hence the low HP number (relative to torque). The car was also quite heatsoaked, we didn't have time for a full cool down. But that gives a good representation of real world performance! This car does have a stock pulley combination as well.
