Fast lsxr 102 intakes expanding lung capacity we strap our 99 t a down to the dyno at ramsey s performance to test the factory ls1 intake versus the ls6 and fast lsxr 102.
Ls6 intake vs sheet metal intake.
The test was run on a 5 3l ls with a comp cam and valvesprings so it could handle some rpm and boost.
In this video it is an intake manifold shootout between the factory ls6 long runner intake and an aftermarket short runner sheetmetal intake.
Compared to the ls1 the ls6 offered an additional 22.
The test was done back to back on the same day with all variables staying consistent through both tests.
