Fd T04z

Just posted my dyno sheet on the Dyno thread.
Made 450 rwhp at 1.3 BAR (18.8 psi), ran out of fuel Pump so could not raise boost further.
On the wastegate (10psi, 0.75) I made 353 rwhp.
Getting a swirl pot and bigger pump so I can run 1.6 BAR, hoping to get the magic 500rwhp

You raised the boost 9 psi but made less than 100 more rwhp?

the HKS version comes with a 1.00 hotside. The garrett version you can specify 1.00 or 1.15 or 1.30.

Goodfella, I went for a conservative rich tune, I may have got 480 rwhp if we went a bit more aggressive on the AFRs but didnt want to risk it just yet without WI. Plus our Dynos over here read smaller figures then an American dyno.

I have no idea how a T88 compares, I know a T88 runs out off puff at 1.2 BAR on a ported motor, where as the T04z is most efficent at 1.6 BAR, plus the T04Z is ball bearing where as a T88 is bush bearing

When you getting your new fuel setup sorted Mark?
Don't believe everything your told about t88's running out off puff at only 17psi.

I'm too busy sorting everyone else's cars at the moment. No time to sort my own. I'm fitting a replacement gearbox, gearbox brace, egt gauge tripower twin gauge pod hold, another nozzle for my water injection, bigger fuel lines & custom tin intak pump setup, then a remap. This is all when I get to actually spend sometime on my own car.lol
