How much horsepower does a 102mm throttle body add?

FAST® engineers teamed up with airflow specialists at RHS® to develop polymer intake manifolds for GM LS based engines. Testing on a near stock LS7 engine with a Big Mouth 102mm Throttle Body™ produced gains of 16+ horsepower, and 26+ rear wheel horsepower on a 500c.

Is the Dorman LS6 intake as good as an LS6?

So Trick Flow Specialties recently tested the Dorman intake on one of its LS test engines.

The Dorman LS6 replacement intake manifold (denoted by the red line) delivered nearly the same power as the original LS6 (blue line).

Should I upgrade my LS6 intake manifold?

The intake manifold and heads can only hold and flow so much air so they quickly become the restriction.

Unless you are adding these mods you just don’t need more air than the stock intake can supply.

Is there an LS2 intake for the ls1/ls2?

Dorman says it also has a 90mm LS2 intake in the works that will be a true performance upgrade for the LS1/LS2 manifolds and an improvement on the original LS6, too. The bottom line is less scrambling (and less money) for LS enthusiasts looking for that quick LS6 power upgrade.

What kind of throttle body does a GM LS6 have?

Both the original GM LS6 and Dorman intakes were mated with a 78mm throttle body; the FAST manifold (black line) used a 90mm throttle body for its test. The engine also sported a set of Trick Flow LS cylinder heads, which were being tested.
