Installed EVO Intake, Holy Crap!

[kt1]

Honestly guys, I wouldn't knock Brad Roberts, many 'tuners' say they gain this and that from "feel" but you cannot feel such powers, it's incremental to what you're already used to and negligible by a 'butt dyno.' Only real way is having a dyno run before and after that intake install with same weather condition. If the intake didn't sit in the engine bay like that and actually had an element filter right at our side vent and smooth mandrel bent tubing going to the TB than maybe it'll help.

Side note: So does that X51 not bolt on to the 986's stock manifold's bolt pattern on the heads? That intake manifold looks to be a beast if you had port work done on the head for easier breathing of the engine.

Where are you getting the idea that the EVO doesn't go to the side intake? The pipe that runs from the EVO to the TB is stock. The EVO comes with a cone filter, small metal pipe to attach the MAF, and a surround that prevents hot air from the engine being taken in. All air comes from the outside.

well I can say this with one hundred percent certainty... a 3.2 intake manifold will NOT fit on a 3.6... the bolt pattern is different... one side (dont remember which) could be drilled and tapped, but the other couldn't


ANYbody have a part number on that 3.6 x51 intake manifold and TB????

"Real live engineering data says the actual inlets on the side of the Boxster are TOO LOW. If Porsche had moved them up on the sides of the car, they would actually flow more than the 50% they flow now."

Not only that, but you would not be sucking up brake dust from the front brake. All it takes is a couple of hundred miles of driving and a clean filter element is pretty well covered with the black dust.....
