Valve Bounching

[drgnball34]

I read an interesting article about valve " bounching " or " floating ". It included a dyno sheet of a car that suffered from it. The power levels drop and shot back up like a yoyo. My question is if my R34 GTT was producing around the 300rwkw, would the standard valve springs be able to handle it? Having all that power is one thing, but getting to it smooth and constant is another

Its is impossible to say over the net

Its a thing where you will or wont have a problem.

I never did, and i know others that havent. But i also know of people that have.

So its mainly based on the condition of the head, which your tuner etc will be able to acertain

Probably be alright though.
