we looked at the gvwr on his car and subtracted 800lbs (usually pretty close)
edmunds says manufacturer claim is 3229 for the 09+ wrx, edmunds weighed in at 3232.
so not quite 300lbs lol, they have my car at 3140lbs so it's less than 100lbs i guess.
they only have percentage increases for the 09 but 18% more hp and 25.2% more tq comes out to 312bhp and 305tq.
the 07 has 27hp less but 30tq more than the 09 and weighs almost 100lbs lighter.
That's with the cobb tune on the 07 tho, i dunno what the bullwinkle tune puts out for BHP/TQ.
