Have you ever seen a tech drain coolant from an engine using a shop vac? We did when Bryan Rogers hooked the ol' Hoover up to his Cobra. This does save undoing hoses, but it also sucked all the water out of the engine, not just that in the heads and intake.
As BBK continues its march from parts packager to bolt-on manufacturer to, now, an engine parts maker, it is introducing consistently more sophisticated parts. The company's latest push is intake manifolds, so, besides the Single Stage Intake for 5.0 engines we're testing here, BBK has introduced Chevy LS1 and Honda intakes as well.
Because of the high-rise design of the BBK lower intake, dedicated fuel rails are necessar
It's also likely we'll see even more intakes from BBK in the not too distant future as this ever-growing company ramps up its engineering and manufacturing muscle. But for now, we went to BBK's distribution arm, Brother's Performance Warehouse, to watch the brand-new Single Stage Intake bolt onto a 5.0 test car and get the numbers on the company's in-house chassis dyno.
As luck would have it, our visit was mere days away from using pure production parts. The castings we worked with for this article are thus last of preproduction prototypes. They were cast from production tooling, however, and the only meaningful differences from run-of-the-mill production SSI intakes is they had been beaten up some from being bolted on and off the car repeatedly during final development. That work had mainly consisted of trying minor shapes inside the plenum as BBK searched for any possible last-minute horsepower before signing off on the production tooling. No secret bumps or hollows were found, so the SSI production was set to begin just as we began to pen this story.
Obviously, the BBK lower manifold is from the staggered rectangle school of design. This a
While we have previously described the Single Stage Intake in detail in our March '04 issue ("Early Warning," p. 130), by way of quick review, the SSI is an open-runner, high-rise, twin-plenum intake for 5.0 engines. It is aimed at the typical bolt-on Mustang-with the usual exhaust system, short-tube headers, large mass air meter, throttle body, and so on. An intake in this market needs to demonstrate a clear superiority over the stock inline-oval intake, and preferably compete head-to-head with the dominant aftermarket offerings.
Installing the SSI follows conventional practice. The old intake is stripped of all its fittings while on the car. Then the intake is removed, the fittings are transferred onto the BBK intake, and it is installed on the long-block. We've hit the highlights of the install in the photos and captions, but expect no surprises. The only caution we can note is to fit the PVC parts to the lower intake before installing the intake as clearance at the rear of the SSI is limited.
