I plumbed my boost gauge in today and it peaks at 26psi and holds there but I'm sure I've heard 26psi is standard pressure and my car is definitely remapped. But it produces 26psi from 2000rpm onwards.

I can pull away from a 180bhp pd130 bora easy. And my mate I bought the car off says it's mapped to about 180-190 and there's a receipt for it. Could it be the actual on the turbo holding it at that and could I fit a boost controller?

What sort of bhp and pressure are people running on here? Psi or bar. Thanks in advance.

Do the sums and it's obvious that 26PSI isn't remotely standard. 1.3bar is standard.

 

1 BAR = 14.5PSI or thereabouts.

I thought it was high for standard but I'm sure I read somewhere that 26was standard or could of been what most people run after remap. Thanks for confirming it. And way of getting it to boost a little bit more than 26psi as it produces 26 from 2000rpm onwards all the way to 4500rpm. Would a boost controller work or should I just go for a front mount so it's less restrictive than the side mount

Aaron, does you car smoke much? Even if 180-190bhp was possible on the standard PD130 KKK turbo, it won't last very long before giving up the game.

 

A good reliable stage 1 map on the standard turbo tends to be 170bhp tops. When I had a stage 1 I went to a Shark dealer, and the map was around 165bhp. However, the map was very smooth and didn't have any clutch killing torque spikes either.

 

No need to worry about boost controllers or anything with these. First step should be to get a decent map on there!

 

Mine has a PD150 hybrid and is around 220bhp, so let me know if you want a comparison, as I'm in Wrexham also...

It doesn't leave any soot on the back and the bora I raced said it didn't really smoke at all but that could be because it's had a recently new turbo before I bought the car.

I know it's a garnett but don't know if it's a 130 or 150.

It could be my boost gauge maxing out at 26psi as it's digital so I'll contact the manufacturer and find out

If you have a laptop you can use VCDS-Lite to datalog the boost pressure that the turbo is delivering and also see if it matches what the ECU is asking for.  It's quite useful to have for the sake of £10 for the cable and you can datalog a lot of other things too. 

 

The requested vs actual boost shouldn't be massively out in fairness and if it is it would go into limp mode to try and protect the turbo in most cases.

 

I've read somewhere on here that the upper limit for boost pressure on the standard KKK turbo is in the region of 27PSI for reliability. If your pushing that or above chances are you do have a fairly aggressive map on there. I wouldn't push it any further unless you want to be budgeting to replace it once it goes!
