I am the pleased owner or a XC90 T5. Love the car, but feel it could do with
just a little more power. I am told that the turbo is set low and in fact is
running at only 30% of it's potential.

If that's the case, I would like to know if anyone has increased the turbo
output and if so what difference it made. I am aware that doing this may
void warrantee on the turbo, so I may wait a while before I do it.

Any comments appreciated, thanks in advance.

Go to www.powerchipgroup.com and you can purchase a powerchip for your car
to increase its power and torque. This is the Australian website, but the
international website for your country can easily be found here as well.
 
Cheers Peter! I'm actually in Sydney so I'll check it out.

Other ideas from anywhere are still MOST welcome!

Do you mean the XC90 2.5T or the T6? I don't see a T5 listed on the
Australian Volvo website.

If I'm not mistaken altering pretty much anything on your car may void
the warranty for the entire vehicle not just the turbo. If you
increase the turbo boost you are not only stressing the turbo more you
are also putting more strain on the engine block, pistons, valves,
intake system, ignition system, etc...

Jordan,

No it's the T5 (2.5l 5 cyl turbo) not the T6.

I am getting some advice from a mechanic who I think is going to suggest the
installation of one of those performance chips and a "tweak" of the turbo.

I appreciate the warrantee issues and will consult with Volvo Australia
before I do anything.

In regards to increasing the turbo boost, I would only take it up a few
notches and not to the point on stressing the motor, that's the last thing I
want to do. However, my initial advice is that Volvo have not held back full
potential of this motor and the turbo (maybe for the next model) and I am
looking to tap into some of that.

I notice that in overtaking maneuvers, the T5 can be a little short on speed
which is a little unsafe. That's why I am looking for another 10-15%
improvement in power. Basically that will take it up to T6 specs.

Thanks so much for your thoughts, much appreciated.

Well you have 208Hp and 236 lbft of torque right?..... They've gotten 300hp
out of a slightly modified version of that motor, in the R cars... and 240
something hp out of it in the T-5's.... I don't think it will have too much
of a reliability issue, tho I'm not at all sure if the T-5's use a different
turbo or some kinds of reinforcement to handle the extra power... But it is
basically a similar engine.
