Nov 26, 2019 · Learn the ignition timing number. Look for the ruler-style row of numbers on the front of the engine's harmonic balancer (or flywheel), which should have numbers above and below zero. Typically, when your car comes from the manufacturer, ignition base idle timing is set to a manufacture specification before top dead center.
The stage 1 LS3 supercharged camshaft is a great camshaft with conservative duration for a mild lope at idle and excellent driving characteristics. This camshaft is designed for LS3, LSA, and L92 supercharged applications that are running a factory torque converter.
The popping is a result of the air/fuel mixture becoming very lean when the throttle is closed and the engine is rotating well above idle speed. It is also necessary that the exhaust system have rather open mufflers.
Mast is THE leader in LS cam technology. Want proof? We had variable valve timing cams 18 months BEFORE anyone in the aftermarket. We design our lobes IN HOUSE using proprietary software. We test each cam on our NCRS Superflow engine dyno in actual applications to find the best power curve. Then, we test each profile i
It depends on the car. High performance cars like a Corvette, Viper, Porsche or BMW and turbo charged cars like a WRX will see improved throttle response and power. Cars with carburetors can be tuned to run RACE GAS and will see more power, (changes will need to be made to the carburetor jets and the timing).
The PCM regulates engine intake air at idle with an electronically controlled device called an idle air control (IAC) valve. If air is introduced to the engine that is not regulated by the PCM, it may result in a rough engine idle at cold start and a code P050D being stored.
Converting an LS engine to a carb might seem like taking a step backwards in technology, but there's something to be said for "tuning with a screwdriver" simplicity. Read along as we show you how a standalone ignition system and aftermarket intakes can help all you carb junkies take full advantage of LS power...
