    Mazda 13b w/ Tracy Redrive

    Curious, how much horsepower do you estimate you're getting now, and much do you prefer to have? Is your current horsepower limited by some aspect of the installation (coolant or oil temps)? Thanks, John

    Thanks for the reply Marc. I thought the VNE/0.9 was a prescribed minimum relationship to Vd, enacted to prevent manufacturers from setting an arbitrarily low Vd. I've not read it as the required absolute relationship. I get it's probably a valid assumption to use for our purposes with E/AB.

    Gear Box Failure @ 43 Hours
