> Adding 20% would be wrong. You’d need to do some cross multiplying to get the “right” number if it’s guaranteed 20% loss from crank to wheels. 80/100=238/x… 80x=23800… x=297.5. Close, but I just helped you get $1000 more for the car since you only said 290 lol.

Call me dumb, but I have no idea what you just did? I usually estimate a 20% loss in crank to wheel horsepower no? The f1 tune claims a 30% increase in horsepower, just to make it believable I only added a 20% CRANK hp increase which would be 58. 58 plus the existing 290 CRANK horsepower would be 348 CRANK horsepower which is how I came up with my number. Like I said earlier, I find it a pretty good sales techique to advertise crank horsepower when selling performance cars as is just looks better lol.
