IpsoFacto I have got my stock 285bhp V70 T6 P3 being dynoed today to set my base parameters.On their way now are:OSX 3" downpipeBSR Tunedo88 IntercoolerI will post the horsepower improvement figures after each installation if anyone's interested?
IpsoFacto Here is today's print out of the stock car. 145.9 kW (198 WHP) with 307Nm of Torque at 3200rpm
Spac Philia_Bear That is a lot of driveline lossRolling road dyno seems not crazy. Allowing for the usual rule of “kilowatts at the wheels is half the horsepower at the flywheel”, and it is in the ballpark.
IpsoFacto If I run those spec figures through the calculator here https://www.mk5cortinaestate.co.uk/calculator4.php285hp at the crank should be 229 hp at the wheels. So there is excess loss.Any ideas to focus on now before the tune arrives?
Jamest5r_ Looking at that afr graph it doesn't look like boost is coming in until 4500rpm,thats when more fuel is being thrown in, and not that much fuel either.
Jamest5r_ Here is an old graph of mine (2.3 block) lots more fuel and from about 3500rpm which is where you'd expect Max boost to start from. Sorry for the crap picture I took it with a potato,
IpsoFacto you're right - I don't get any turbo kick in my car, and that's evident looking at both charts
