Question on the turbo S40-V40 2004

Hi all,

Yesterday had a good run on my newly acquired V40. I've never had a turbo volvo before but can anyone enlighten me when does the turbo actually kick in? Can one actually feel the turbo coming in?

I went up to speeds of 130km/h but never able to reach 3000rpm (the 5speed tranny with the torque converter keeps this down I guess). And up to those speed, the increase in power was gradual and smooth. I've heard of turbo lag, does this engine suffers from one?

Thanks all!

    The 5 cylinder high pressure turbo in the 850/70 series cars doesn't get much boost until over 3500 rpm. The low pressure turbos kick in much lower, but does not generate a lot of noticable power.
    I assume you have a low pressure turbo, so the engine will not have a lot of additional torque when the turbo kicks in.
    You will need to hold the transmission in 2 or 3 and give it a lot of gas at 1500 rpm and "feel" the torque at 3500+ rpm. But a low pressure turbo is merely an assist and will not do a lot of boosting.
