  • stock torque/hp

    does anyone know a rough stock, torque and hp to the rear wheels. i want to know cause ive been modding my car little by little since i got it and now im going to get it dyno'd shortly but i dont know what stock to the wheels is.

    thx for any info

          torque/horsepower are measurements of each other.. let me drink my morning coffee and i will be back and calculate it

            it would be ~171 ftlb of torque

              And just to muddy the waters a little; when I had my '02 on the dyno (manual trans), bone stock it's best run was 164hp and 192tq. After installing the K&N FIPK the best run (of 2) was 169hp and 192tq. Different dynos, different operators, different weather, different mileage, different tires...etc, etc, etc... Your mileage will vary :)

              Just curious cam98aro, what formula did you use to calculate tq from hp? I thought you needed to know the rpm at which the max tq was made to get that figure.

                I don't like seeing those numbers, makes me sad...I would like to still think that mine is rated at the block hp...not the ground hp...k, thanks...

                  No problem...assuming 17% parasitic loss, with the K&N kit I made 204hp and 231tq at the crank. That better? :D

                      torque= hp x 5252 / rpm of hp

                        No offense, not trying to be a tool here, but where did the 5252 come from? Is this standard for all torque ratios?

                          yes, it is a standard number, you can flip the equation to figure out hp from torque numbers.

                          hp= rpm x torque / 5252

                          so for instance, if you have 500ftlb at 5500 rpm, your hp at that rpm is:

                          ~524 hp

                            5252 is the rpm at which torque and hp are equal. Look at any dyno chart and you'll see that the torque and hp curves always intersect at 5252 rpms. A chassis dyno really only measures torque - it uses the torque figure to calculate hp. The formula for calculating hp is hp=tq*rpm/5252.

                            The reason I was asking cam98aro about the formula he used was because I always thought is wasn't possible to calculate torque from hp. As it turns out I think I was right - the formula he is using calculates torque at the peak hp rpm, which would not in fact be the peak torque rpm.

                              the formula is used to calculate the torque the engine is making at any rpm, you just need to know how much hp it is making also

                              but you're right, i calculated it at the highest rpm, even though the torque may be higher/lower at that rpm than its max, but thats the best all around guess from looking at that dyno sheet IMO
