    I'm sure this has been asked before, but I want an up-to-date fact. What's the maximum amount of horsepower and torque that I should run to my 420a? You can see my current specs and setup in my DSM profile. I have multiple performance parts and forged parts that are meant to take a beating. But I am concerned about my block. What's the breaking point? Am I close? Should I stop striving for more power?

    I've seen neons running 500-600hp on a built 420a. The block and crank can take alot of power. What will take it out is when some other part breaks and grenades the engine.

    like if the engine drops a valve cause the timing belt broke when your were at higher RPMs so the valve breaks instead of bends

    Or if your car isn't tuned properly causing pre-ignition and detonation.

    Keep going until you break LOL. And then rebuild, possibly backing off a little

    The only thing I'm concerned about is my timing belt (it was $25 at RockAuto). But I guess I can get the $90 one and not worry! :cool:

    And I guess if it can hold more power, then I will make more power...

    Yeah, just keep going as long as you feel comfortable. The point I am trying to make is with all the "how much power can I make with X? others made Y", parts are no guarantee. You can pop a motor at low power with forged internals, all they do is increase your buffer zone when on a bad tune or when something else lies, like a wideband.
    Inevitably, it all comes down to the tune and truth in the feedback you get.
