Stock wrecker engine 537whp.... and climbing.
I run a stock wrecker engine in a Jimco offroad race car. It's currently pulling 537whp on just over one bar of boost. However given the boost control issues we have using ported garret GT2871 internal wastegates it's spiked on the race course to where we're pulling substantially more.... and I'm keen on testing that on the dyno (when money allows me to pop a little VQ)
The stocker has been more reliable and is easier to drive than the highly stressed Cosworth VQ engine that currently sits spread across most of my workshop.
Next move is to push mid 500's out of the stocker and if it blows I'll revert to the Cosworth VQ.... but for the moment the stocker puts out more than enough power for one hell of a big smile.
