Re: Basic boost increase?? Posted by Ari [Email] ![]() ![]() In Reply to: Basic boost increase??, Alex, Tue, 25 Jun 2002 15:21:12 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Under normal conditions, the APC runs at full boost. If it detects knock, it will reduce the boost. The lowest level it can reduce the boost to is 'basic boost'.
The level of basic boost was chosen as the 'fail safe' level for the car. At basic boost, even with low octane fuel on a hot day, your engine shouldn't knock.
You really don't want to increase the level of basic boost. It's there as a safety in case something goes wrong - like you get a bad batch of gas. If everything is right, you should be running at full boost. It's full boost where you get your full performance, and where you want to concentrate your efforts.
With increased fuel flow (say you upgrade from a 2.5 to 3.0 bar FPR), you have more fuel available, so you can run higher full boost levels. There are a bunch of ways to to this, but increasing the basic boost level isn't the one I'd recommend.
