I have a 96 volvo 850 turbo wagon. It has turbo lag, obviously, and I dont like it. This is probably one of those things that are impossible to fix, and I bet a manuel transmission would go a long way in fixing it. Im not gonna do that though. Anyway, how can I get a bit more off the line punch. Would changing the blow off valve or waste gate do much, will a chip co much for this, an exhaust, etc. I did add a air filter, but that was only marginal towards fixing the problem. It does make a cool noise though, hehe. Anyway, anyone gotten it so that when they launch the car you get a little wheel spin, or that sports car take off, rather than the granny take off until the turbo kicks in. I mean when Im at a red light, next to a r$ce Burner, and we floor it, and we are neck in neck until my turbo kicks in, it just doesnt look as good as when I can blow them away. I like its power once its going, I mean when Im on a track, or braking the law, and going in excess of 100 mph, its acceleration through there is decent, not great, but decent. Anyway, some help would be greatly appreciated.
I will leave the technical aspects for the experts...Perhaps a wastegate adjustment will help a bit but I doubt it will cure the lag (come on man, it's not that bad!).
One thing that a lot of turbo owners don't do is launch their cars the right way. Because the car is a turbo that does not mean that, while at a standstill, you just mash the gas pedal down to the floor and the car will spew flames from its exhaust! You can try a couple of things: one is to get used to using both feet when driving (takes some practice, spend the time in getting used to it), meaning left foot on the brake pedal and right on the gas. While you wait at the light (and while you are trying to block the sound of the r1ce fart muffler bellowing) try to build th RPM up to about 2,000 (at 2,200rpm your Turbo is ready to go) and when the light turns green, well, let "nature" take its course.
I, personally, like the "gradual" acceleration. Just rev up a little bit (no more than 1,200 or 1,300 rpm) and when you are ready to go, push the accelerator only about 3/4 of the way down...not all the way, you may get jumped but it will only be momentary (and that is a big "if")...as you go into the 2nd gear (you have to know when your transmission switches--I assume you will be in "Sport" mode anyway) then you MASH it all the way. I guarantee you that you will accelerate quicker this way. You just have to practice it a few times, on your own, as if you don't get it right you will be chasing.
I don't know how old you are but...be careful! Only do this when you have an open road ahead of you...not in traffic. It's not worth it. Just let idiots who want to race you in traffic win...The best racers are the smart racers. Pick your battles and you will always come on top!
