Installation of crossover manifold !!
After a long delay due to cold weather, then pollen storms, and finally monsoons I got to replacing my intake manifold. I modified the larger Needswings intakes to include crossovers for better breather.
It took me an hour to do the swap, and then a quick trip around the block to confirm that everything was working as intended.
Details:
Pulling the manifold was easy as I glue the gaskets to the engine and add grease on the manifold side, so the gaskets typically can be reused. The driver side gasket was warped and had a 1/32” leak that was not noticable. The engine had thrown a code once for a higher than expected idle. Interesting.
I would have been done sooner but I had to drill and tap two vacuum ports for my electronic vacuum/boost gauge, fuel pressure management system which adjusts the rail fuel pressure. The installation was easy and the design that Rob came up with was very superior to my initial approach. It was necessary for me to fight the crossover hoses, this new design was easy pezie, well done Rob.
The appearance is very attractive, functional, and well thought out. I can not attest to the improvement power wise, but it sounds good and I believe the exhaust is a bit more present in tone.
If you want about 20 more HP, this is a no stress way to your goal. Pullys give you more boost at the stress on the idlers and belt. With this manifold the boost YOU SEE will be lower than you have had before, BECAUSE THERE IS BETTER FLOW AND LESS BACK UP RESTRICTION IN THE MANIFOLDS. A gain in power and a bit more response, whats not to like.
The album has the photos of the installation and some details about my approach to this project. Please take a see:
