Turbo Boost psi?

rcflyers · **February 05, 2015, 19:59:22**

Does anyone know what the maximum turbo boost allowable is on a 2009 1.6 CRDi i30 116hp please?

Thanks.

Yes, somebody does (but not me sorry)

I have recently replaced the turbo cartridge and need to adjust the VNT stop screw and actuator rod.

I drove the car today and at one point the turbo boost peaked at about 21 - 22 psi.

Most of the time it was around 16psi but if I drove the car at high speed the boost crept up over 18psi.

Does this sound like too much boost?

Cruiserfied will probably Know! How did the performance feel compared with stock?

I'd already had a look. I don't have boost pressure readings as such. I work on what voltage the sensor is at.
Also I wont advise, in this case, on a UK vehicle which possibly runs different ECU mapping to what I have available to me.

It felt ok, maybe a little quicker than before.

Thanks ..

Hopefully someone who has played with boost will know.

I'll floor mine on the way home and see what it says.

Not very scientific but it might help.

Do you have 5spd or 6spd?

rcflyers · **Reply #8: February 09, 2015, 18:12:54**

Thanks, mine is a 5 speed.

Probably say chirp!

The most boost I see when really booting it is 19. something.

rcflyers · **Reply #11: February 10, 2015, 19:21:13**

OK, thanks, I will test mine again tomorrow.

rcflyers · **Reply #12: February 12, 2015, 19:38:28**

Results:

When the car is cold the turbo will boost up to around 22psi

As the car warms up the boost will spike up to about 16psi then settle down to 13-14 psi.

I have tested this on 2 mornings on the way to work and the results are the same.

I wonder why it allows a cold/cool engine to boost so much????

Lorian · **Reply #13: February 12, 2015, 19:51:53**

I normally never boot mine while its cold....

rcflyers · **Reply #14: February 12, 2015, 19:57:15**

No, I normally wouldn't either but only did it for testing purposes.

Turbo's love cold air which is denser than warm air. You can buy after market water spray kits for the intercooler which sprays water on to the intercooler to keep the intake air cooler

Phil №❶ · **Reply #16: February 12, 2015, 22:50:11**

Yes, even though the air is intercooled, once the exhaust gas hits the turbo shaft, a lot of heat energy is transferred into the cold side, which reduces the turbo's effectiveness. Whatever this reduction is, most likely determines the size and design of the turbo.

Hi iv had mine remapped and on my way home from work the other morning my 1.6crdi was peaking at 24psi

Thanks, was that with a cold or hot engine?
What hp are they claiming your car now has?

no1chunk · **Reply #19: March 05, 2015, 12:51:05**

Tht was just b4 it reached warm up temp now there sayin its approx 150bhp from 113 and approx 240ft lbs of torque wiv better mpg aswel but abnt paid to much att to what its improved by just noticed a slight improvement its mainly been done for towing caravan purposes

Doe's anyone know if you send your chariot into a HY dealer for a service and they check and find it need a ecu update do they just update the parameter that needs updating or do they do a complete update?

reason for asking is that you send your car in for service and they update the ecu program it will wipe off your remap

Wingerdave · **Reply #21: March 05, 2015, 15:06:14**

ECU update is just that, complete update of the chip. Unless you tell them to put the old parameters back in, they're gone.

Same as flashing your BIOS on a computer

Johnno · **Reply #22: March 05, 2015, 15:22:29**

Your buggered then if they update it,

CraigB · **Reply #23: March 05, 2015, 15:32:43**

You wouldn't remap your ECU while still under warranty ( well you could but that would be silly ) so by the time warranty is over then it would be very unlikely that Hyundai would ever do another ECU update so any re-mapping should be safe.

Then there's that, yeah. So probably good, but ask first.

Okkan · **Reply #25: March 17, 2015, 12:20:50**

Sounds 100% right.

Checked it with the scanner at work last time I had it plugged in. So ecu reading not off a gauge.
