You planning to drive a dyno?

It's a pretty well documented fact that hyper pistons are more sensitive to detonation, especially at high horsepower levels. They tend to fracture while forged pistons tend to just deform.

Pretty sure the tune on a 1000hp engine is pretty conservative and designed to not rattle the pistons regardless.

But go ahead, run cheap pistons in a cheap build and be sure to share the results.

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
