K SERIES HUGE INTAKE MANIFOLDS...MY EXPERIENCE

Описание: This is just a run down of my experiences and testing that I've done with the large plenum intake manifolds on my K24 engine and my conclusions I've come to that help me decide what route to take when dealing with naturally aspirated power.

The intake manifolds shown in the video are the K-Tuned side feed intake manifold, and the Skunk2 Ultra Race center feed manifold Descriptions listed below.

K-TUNED:
The K-Tuned Intake Manifold features a very large 4.78L sheet metal plenum shaped in the signature tapered Magnus format. If you look closely at the plenum base and the TB flange, you'll find two custom 6061 billet aluminum pieces that are precision machined using a CNC 3D profiling process. This special CNC process is what ultimately helped make this manifold design possible, allowing us to make the necessary multi-axis CNC cuts. The 90mm throttle body flange matches up perfectly to the plenum and is tapered inward to ensure there is no restriction to the incoming air. The throttle body bolt pattern matches up to the 86-93 Ford Mustang 5.0L specs, which means our K-Tuned 90mm Throttle bodies will bolt up seamlessly. The custom billet plenum base is a work of art, with four precision machined internal V-stacks that are designed to increase runner entry air speed. We also provided 3 x 1/8 NPT vacuum ports that are neatly tucked away on the plenum base, and positioned between each runner. The runners themselves, measure 5.75" long with a large diameter of 1.875", and are capable of supplying even heavily modified K-Series engines with plenty of air. The manifold flange at the cylinder head is available for K20 and K24 heads and is another 6061 billet piece, that maintains proper port entry and injector angles. Included with our manifold is a brushed aluminum K-Tuned Fuel Rail, which is held in place on a rail mount that is designed to keep the stock phenolic fuel rail spacers in place and accept both stock or aftermarket K-Series fuel injectors. As usual, we include all the hardware, specifically the bolts for mounting the manifold to the cylinder head and the 4 bolts for our throttle body. Last, but not least, we placed an aluminum K-Tuned badge on the front of the plenum to add a nice finishing touch.

SKUNK2 RACING:
Ultra Series Intake Manifolds are made from high-grade 356 aluminum alloy for a strong and lightweight design, CNC-machined for a precise fit, and individually inspected for quality assurance. The large 90mm throttle body opening, 87mm velocity stacks, and hi-velocity intake runners with smooth transitions allow the Ultra Series Manifold to outflow the competition. Designed to be used with built, high-horsepower naturally aspirated or forced induction setups, the Skunk2 Ultra Series Intake Manifold helps provide a new level affordable high-end intake technology to the marketplace.

FEATURES:
Available in 3.5L (4.5L and 5.5L configuration require the purchase of optional spacers)
Optional Billet Aluminum Plenum Spacers in 1L or 2L sizes
Hi-Grade Mounting Hardware
6.5” Tilted & Tapered Hi-Velocity Runners
