#101 Carb Adapter Dyno Test |
|
As you can see, our Part #101 Adapter produced 8 more horsepower at 5,500 rpm than a die cast aluminum adapter.
Test Engine: 355, stock Q-Jet intake, stock ’492 heads and 500 Holley 2 barrel. |
#114 Carb Adapter Dyno Test
Don't make a 24 horsepower mistake! |
We conducted a series of dyno tests on several different types of 2 barrel carb adapters. We ran one of the cheep die-cast aluminum adapters versus our #105 and #114 phenolic adapters. As you can see below, the results are very interesting.
Our #105 adapter out performed the die-cast aluminum adapter by 8 to 24 horsepower throughout the entire rpm range. Is saving a few dollars on a carb adapter worth losing 24 horsepower? |
Test engine: 355 small-block, ported Dart heads, 1 3/4" headers, flat tappet cam, compression ratio 10.5 to 1. New style Team G manifold with stock 500 2 barrel Holley carb. |
