Twin Turbo vs. Single Turbo V6: A Dissertation

JayzTang · 01-14-2012, 05:21 AM

Love this article.

Heat is good when it is in the combustion chamber. Once it transfers to other area, not so much. Remember we have yet to use them 100% of the power from gasoline. Gasoline engine is only 18 to 20% efficient in terms of using the energy from gasoline. The 80% left is part of what comes out of the exhaust - Heat. Turbo is a device to reuse this wasted energy. There is a reason as to why turbos are usually put closest to the engine as possible.

Given the same horsepower goal without budget on the same motor, twins will still top single just because it will always spool quicker for better turbo response. But this is unrealistic because every build has a budget.

Given a realistic budget on the same motor for FI, single turbo usually would be better to hit higher horsepower because 2 turbos with 2 sets of piping will always out-cost 1 turbo with 1 set of piping, plus you do not .
