Those numbers are high for what I have being on the stock snail IMO

208whp is decent. What do they come with stock?


I found this
(************start find***********)
Factories measure horsepower from the crank using bhp. This gives an inflated number because it does not take into account the power loss from the drivetrain. 17% is the approximate percentage of powerloss that a drivetrain causes. For an approximate whp, multiply the claimed horsepower by 17% and subtract this number from the claimed horsepower. 227*.17=38.59 227-38.59=~189 WHP. This is exactly what SCC dynoed the WRX at. This works on all cars but it is only an approximation.

So 189 whp stock--- now we are at 206 thats 17whp with a tune, bolt ons, and a stock snail.. Not bad! So if the efficiency loss is 17% then we should be looking at 241 hp at the crank and 281tq at the crank! SWEET!

My car isn't the fastest subaru in florida, but it's quicker than most cars on the road while getting good gas mileage!! I'm very happy with my power gains, tune, mods, and car.
