Default Kraken low mount Dyno result

Got my car on the dyno after the turbo install, the setup is:

Engine: Stock 1997 BP
Turbo: Pulsar PTX2860R gen 2 .64AR IWG Turbine housing
Manifold: Kraken low-mount
Downpipe: Kraken 3”
Exhaust Size: Kraken 3”
Exhaust Components: Kraken 3" cat + resonator + muffler
Head: Stock 97 head
Intake: Kraken 7inch intercooler + filter
Engine Management: UA4C Speeduino
Boost control: 34B Chinese Mac valve

I did the calibration myself, it was VERY stressful

here is the dyno sheet the Hp is on the same scale as the tq
246WHP 6800rpm
211WTQ 4800rpm
I ramped the boost linearly from 7psi at 3000rpm to 14psi at 6800



Here is the spark map I ended with





I was out of time on the dyno to smooth out the boost, so the torque curve is a bit bumpy. I will sort that out on the street.
Can't be happier with the result.

Very cool,
I'm on the same setup here, but with a Garrett compressor wheel.
My car is at 220whp @10psi on gate, so this seems spot on.
Is this 93 octane? Did you notice any knock during tuning and backed off?

I am on 94 octane (Canada) I did 220whp on gate too, it creeps to 10.5 psi at red line.
I got some knock in steady state at about 3000-4000 rpm at 120-140kpa, took some timing out of it and it seems fine now.
At high rpm it is hard to discern knock from valvetrain noise, I took a look at the plugs, and no signs of detonation on them.

Mee too that is why I made it, I think it would be cool to start a thread like the spool data one but with spark map + boost curve + dyno (if possible)

Measure your car for the 80-120kph thread!

Do you feel like ramping the boost by RPM makes it more drivable? If you were to set it to just hit target boost asap like a traditional tune, where in the rpm would it get there? Judging from the plot, I'd guess 3500ish. Does that sound right?

I do it more to limit the torque at low rpm. I target 10psi to 5000 (peak torque) and ramp up the boost to redline to flatten the torque curve. this way my peak HP is high with a low peak torque.
Spool is relative to load so in 2 gear I reach 9psi at about 4000rpm


in 5th gear at 3000rpm
