    Stock 98 WS6 true hp????

    Hi, Im new to the site, just curious if anyone knows what hp my 98 trans am ws6 came with from the factory. I know the 320hp rating they advertise was under rated for whatever reason, just curios what im actually dealing with.

    Every car is different. If you want to know for sure, go take it and have it DYNO'd.

    HP numbers are just that, numbers, and don't really hold much weight. These cars range from 280rwhp to 310rwhp from the factory depending on many factors.
    It's on jackstands.

    Ok, that makes sense. I'll have to see if I can find a dyno in my area. also when you say the hp numbers don't hold much weight, are there numbers that do? like 1/4 mi. times or something?

    You got it. Reason being is a car can have 500hp and do nothing but spin the tires and get beat on by a car with much less power and a properly set-up suspension/drive train to effectively make use of the power.

    Like Jon said,

    ET's, 60ft, 1/8 or 1/4 mile times are all that count.

    I had mine dynoed after I first bought it to tell me if anything had been done to it, and if it had what it came from the factory with. Mine dynoed at 324 RWHP, and 338 FTLBS Torque. That told me that it was good, and hadn't been messed with. I only used my dyno time to see about those two things. There are also two different types of dynos, and they will read quite a bit different.

    If yours DYNO'd that, it wasn't 100% stock.

    Hardman,
    Dyno's are interesting. Great to see where the car is before you turn a wrench on it, and to see what progress you made afterwards. It will give you a pretty good guesstimate of where the car should run at the track although there are many variables that can skew that guesstimate, it's still nice to know what you are dealing with.
    Might even want to find a good tuner that will use that dyno time to tweak on the tune and squeak a little more power out of it. Usually worth 10-25HP additional depending on the car. It's something you'll feel a difference in.
