1999 V70R Slow throttle resonce

Post by victor vector » Tue Jul 05, 2016 1:57 pm

Since I've had this car (1 year) the throttle response is not snappy. I stomp then gas pedal and it will take a couple of seconds before it really lights up. When it does, it's great. This is not a bad problem other than I'd like it some times to just go band when some punk in a tuner gives me the opportunity to 'surprise' them !!

Is there any wisdom and experience out there around this dilemma ??

Jack.

Check to see if your wastegate is set correctly. Your model is sensitive to wrong adjustments of it, so don't mess around - get a pump with a gauge, and check your numbers to see that it's opening at the right pressure.

Other than that, you have to remember that these are high pressure turbos - they don't spool up immediately, like a low pressure turbo. The bigger the turbo, the longer it takes for it to spool up. What you can do, of course, is switch to a larger downpipe, ported manifold, 3" exhaust, etc... but that means an ECU tune as well.
