Default WHP--> Crank HP, conversion?

Hey kids;

Well, we had our dyno day (dynojet) this Saturday and as you can see by my signature I did pretty well, especially in the torque department. So, I am trying to figure out how to convert these numbers to crank HP.

I have seen a ??X1.15 but that does not seem to add up.

238WHP X 1.15 = 278?
I know the TXS website lists their stage 3 at 326HP.

So is there a definate formula or is it just a guess thing?

Thanks.

Steve..

For a dynojet you can go on about a 20% drivetrain loss, maybe a tad less closer to 15%

so 238 x 1.15 = 273 (your calc needs calibration)
to 238 x 1.2 = 285

inbetween those 2 numbers is a good guess
