    Post How to build boost

    Hello - I am a newbie. I have a 05 STI. I have been reading the posts about launching and a lot of them say to build up the boost before u 'slip' or 'dump' the clutch. I have revved up to 3 or 4 K and do not see the boost gauge going up over negative much. Can someone please help me with building boost before launching. Thanks for your patience.

    I'm not too sure what they are talking about...you can't build much (if any) boost without a load on the engine. Unless you have an anti-lag system or launch control, the best you can do is rev it.

    0 is better than negative... just hold your revs up and slip the clutch and you'll take off just fine. some people have the launch down so well that they can have the car idling, then stomp on the gas just the right amount while slipping the clutch do build a slight amount more boost than by just holding the RPMs, but its tough to do and i dont know if there's really too much benefit to it.

    I noticed that if I lightly rev the engine a few times (up to like 1.5-2k), the boost will climb a bit, but I have to be prepared to use the boost otherwise I've just wasted gas.

    I remember reading about launching at the tracks and people saying to vary flooring your revs between 4000rpm-6000rpm or so and this will allow the turbo to spool. Then right before you're ready to go keep it floored at a "reasonable" rpm point and slip the clutch (no dumping here!) and you should get a good launch. I dont drag race, so this is just from what I read. G'luck
