I've finally had the XF dyno tuned.

Car running :

To4 turbo

External Wastegate

3" Mandrel Exhaust

Standard Engine Internalls

FMIC

480cc Injectors

Max Power At The Wheels: 174KW At 7psi

Power was limited due to myself buying the cheap microtech fuel only ecu, therefore not having total control over timing. Now wishing I bought the fuel and ignition version!! But still happy with results. More than doubled original power

Interesting first post

car seems to be making some pretty decent torque given the power made, or is this a function of the gear that was run V dyno calibration. Torque just seems a little high to me. No doubt the experts will be along later

Thanks

Yes torque is at the wheels so its multiplied by the drivetrain. Hopefull those experts can work out what it would be at the engine.

Dyno was done in 3rd gear and vehicle has a 2.77:1 diff ratio. Cant remember from trade school how to work it out.

Using guestimates at flywheel power.

228Kw @ 4800rpm = 450Nm

230KW @ 4400rpm = 499Nm

120kw @ 3400rpm = 450Nm

80Kw @ 2400rpm = 318Nm

Keep in mind, guestimates only...

Nice work, 170ish isnt too bad for a fuel only tune.

Get a better ecu so you can sort out the timing and it'll go well over 200 on that boost level.

My old ED turbo ran 204 on 8psi from a sketchy road tune I did on the old V3 Wolf3d... they were some fun days, then I got it up to 270 odd wkws... 215 tyres and an open diff... steering the bum was a handfull

that's not a bad start at all - especially when an XF weighs a few hundred kilos lighter than an BA/BF

Not bad at all. Should go alright

Post up a few pics of the XF mate, I have been thinking along the same lines for a project in the future....

Here is some pics for ya

Nice job mate. I'm toying with the idea of getting rid of the top mount intercooler on mine and putting a front mount like you've done. Can you tell me what size and make your intercooler is and what flow/power it is rated to? Also, I can't see very clearly from the pics but does it have clean supply of air to it ??? ... it does look like it is shrouded a bit by the bumper.
