    400+bhp 4eat flexplate

    Hi
    JDM '95 WRX Wagon 2L turbo
    Does anyone make an sfi approved or heavy duty flex plate? Is the stock flex plate OK at 400-500 bhp?
    Please

    Stock plate should be more than enough for that power range.

    I dont think your flex plate would be the problem, it would be getting your torque converter and valve body up to par to handle that..

    Thank you, both, for taking the time to reply.
    I feel more confident now.
    Rest assured, the torque converter and valve body are being addressed.
    25 years ago, when I was drag racing my, street driven, Plymouth (which I still have) - 11.9 bracket, I changed to an externally balanced B&M flexplate.
    I thought it would be interesting to get to, a street driven, 11.9 again. This time with a turbo and more electronics. All I had before was a voltage regulator and an MSD 6A!
