1 atmosphere [standard] = 1.0132501 bar at sea level

1 atmosphere [standard] = 14.6959503 pound-force/square inch (PSI)

One bar is not = to 14.69 psi

I don't think it matter BHP or WHP....the car makes 270ish flywheel stock...and wiht no modifications it don't just jump 70hp becuase you ask it nicely. you have to make changes in something to come up with 70hp to make 340 crank hp, you probobly need to gain 100+ over stock to see 340whp.

bone stock not = 340hp.

I had my car dynoflashed last weekend (a process where they reflash your ecu and change the tuning a bit). While on the dyno, Al turned the boost up to no more than 20psi. With an intake and 3" turboback exhaust (with stock cat/ fuel pump) I made 290 hp to the wheels. I'm guessing this like 320-340hp to crank (anyone?) While this is pretty good, my fuel pump was pretty much cutting out at that point, so I was running pretty lean. Al recomended that I not run the car at 20psi consistently. So...think about it before turning the boost up. I could probably run 21 psi, but I'm not. At least until I can get a new fuel pump put in the car.

I also have just intake and a catback exhaust with 3" piping. (K&N typhhon& HKS hi-power) HOwever im still running the stock boost setting(19.5psi) How much HP do you think i should be expecting at the wheels and the crank?
