2. K&N FIPK cold air intake/Bassani Quiet Thunder (after-cat) exhaust |
|
Synthetics = ”Free” Horsepower
We wanted to test the efficacy of slippery stuff, so we got our pal Cam Evans at Redline to send some bottles: 5W30 for the motor, D4 ATF for the 4L60E, and 75W90 for the third member. Vinci ran the rollers with the conventional fluids and then with the Redline stuff. Dig it: a gain of 8 hp and 7 lb-ft! |
Yes, most people tease their ride with this combination first and then progress. Though the K&N FIPK “cold-air” system does source incoming ambient air from beyond the engine compartment, all the components remain inside it and the filter element is enclosed in its own little cell that I have to believe does not stay anywhere as cool as the incoming ambient air. I do like the idea of the “forever” air filter element, however. I also like that the Bassani aft-cat system weighs 4 pounds less than the stifled OE contraption. Bassani constructs from 3-inch diameter aluminized steel mandrel-bent tubing (muffler guts are stainless), premium-grade hardware, and gasket-less ball-and-socket connections.
Did the Dual Dudes amount to anything? Traditionally, the affect of these changes is highly subjective. Some people swear they feel the difference; others are not so quick to adjudicate, so they want to measure it…on a chassis dyno. In this case, the two modifications produced a surplus of 10.1 hp and 13.3 lb-ft. (Total: 273.5 hp/318.9 lb-ft)
