Wilson Manifolds specializes in porting intake manifolds. We've honed our craft over decades with the Top Pro Teams so our quality is second to none. We are the cutting edge of intake manifold design and porting. Whether you have a street car looking for some extra grunt, or a dedicated race car that requires extreme modifications for fitment and efficiency, we can take care of you.
We port intake manifolds for road racing, pull trucks, drag racing, circle track, dirt late model, offshore boats, jet skis, motorcycles, air-boats, UTVs, if it burns fuel we can port your manifold.
We offer many different levels of porting the below are three our most common: Competition Porting, Intermediate Porting, and Plenum Porting.
Wilson is known for our Custom porting, every manifold is ported to its specific application. THIS IS NOT A GENERIC CNC Port, we Custom Port every manifold per the specs of each engine build.
Wilson Manifolds has been the GOLD Standard for over 37 years. We have worked with all of the Top Professional Teams for every style of racing. Our Teams and Engine builders have relied on us since 1985 for the best quality, horse power, acceleration, distribution and fuel mileage. Wilson manifolds has designed for GM, GM Racing, Ford, Mopar, Toyota and other OE's. We have also designed manifolds and intake systems for Profiler, Edelbrock, Dart, Comp Cams and many other performance companies.
Competition Port with Head Match
We weld and Customize the Plenum to your engine specifications, we adjust the Plenum volume, Port the roof lines, Lengthen or shorten the runners as needed. We shape and reshape the divider walls as needed, adjust the taper in the runners to improve cylinder to cylinder proper fuel distribution. We weld up manifold ports as needed to correct flanges and bolt holes if mismatched. We only weld and machine manifolds with the proper materials. NO EPOXY IS USED at Wilson Manifolds.
With this service the manifold is mocked up on a square deck with the heads, its is then machined to fit with perfect accuracy and the ports are then transcribed for perfect alignment to the heads. All bolt holes, the end rails, water and the distributor is all checked for perfect alignment and height with this service.
Cylinder heads are required for this service and must be clean and bare.
We have seen up to 40+ HP Gains on average
Intermediate Port with Gasket Match
Heads are preferred for this service to ensure proper fitment but not necessary.
This service is for Street / Strip / Race cars of all types.
We weld and Customize the Plenum to your engine specifications, adjust the Plenum volume, Port the roof lines, Lengthen or shorten the runners as needed. Shape and reshape the divider walls as needed, adjust the taper in the runners to improve cylinder to cylinder proper fuel distribution. Manifold is ported with a gasket match or send us your heads and we will match to the heads.
We have seen up to 15-35HP Gains on Average
Plenum Port with Gasket match
We port the plenum of the intake manifold. We will adjust the divider walls, taper, angles, textures,etc to substantially enhance distribution and pick up horsepower. We can also match the ports of your intake manifold to the intake gasket of your choosing.
We have seen up to 10-15HP Gain on average
This is from Engine Masters Season 6 - Our Plenum Ported manifold against a cast stock and another companies ported manifold.
We can convert your 4150 intake manifold to a 4500 flange for an additional charge.
All porting jobs we do will receive a Wilson Manifolds plaque welded on with a unique serial number, allowing you identifying the job for future reference.
You can either send in your intake manifold (new or used), or we can help pick out the ideal intake manifold for your application. We do NOT manufacture cast intake manifolds, so we utilize intake manifolds from other companies and port/modify them so that they become custom manifolds.
To get started, please contact us through our site or give us a call at 954-771-6216. Our porting services are all one-off jobs because we port your manifold based upon the information you supply us. This ensures that your intake manifold will be the most efficient unit possible.
