The test was done back to back on the same day with all variables staying consistent through both tests.
Ls6 intake vs sheet metal intake.
Tpis modified ls 6 intake the intakes were tested on a mild built streetable 412 cid ls2 with our tpis 1 3 4 headers and tpis calibration.
The test was run on a 5 3l ls with a comp cam and valvesprings so it could handle some rpm and boost.
Designed as a factory upgrade for the ls1 the ls6 intake once again proved its reputation by significantly improving the power of our 6 0l.
The engine was run both naturally aspirated and under boost with both intake manifolds.
