Custom high efficiency heat exchanger, the perfect upgrade for the supercharged aftercooled vehicle.

With dimensions measuring 11″ tall, 25″ wide, and 3″ deep, our heat exchanger dwarf’s the factory units and the competition. The unit and provides increased cooling capacity increase over stock and smaller custom applications. This results in substantially reduced air inlet temperatures. Reduced inlet temperatures mean more power with greatly reduced chances for detonation under boost under all driving conditions!

Don’t be deceived by “dual pass” claims to superiority. Our is 2-core dual pass design with high density fins. Surface area is king when it comes to cooling capacity, and no heat exchanger on the market gives you the functional surface are ours does.

MercRacing’s high efficiency heat exchanger comes with requested customized mounting hardware for installation on almost any applications.

If you need custom options, we can build almost any size or configuration you require. Need AN fittings? Done! Need special bungs or additional bracing? Consider it done!

The Competition Clutch Super Single was developed for cars not quite ready for a twin but needing something more than the conventional Stage 4. The Super Single mirrors a twin disc in the fact that they both are a 7.25″ set up and have a 4140 forged steel flywheel. Unlike the twin, the Super Single only uses one disc and tips the scales around 17-20lbs depending on application.

The Super Single is a must have piece for all-motor/nitrous cars running up to 450whp. Currently available for select applications (Super Single part numbers begin with “4S-”).  Please contact Competition Clutch for a complete product offering.

This water/air intercooler pump is designed for circulating water in water/air intercoolers.

Unlike other bilge pump-based solutions available, this pump is designed by Bosch and Ford specifically for water/air applications.

This pump is Bosch part number 0 392 022 002 and is used in many of the supercharged Mustang Cobras and supercharged Mercedes.

This is an OEM pump. It ships with no documentation. Please check below for pump specifications from Bosch; these are the most detailed specifications available:

This information is directly from Bosch. Unit conversion shows that this pump flows 317 GPH; any seller who advertises differently is incorrect.

VERY IMPORTANT! We ship these pumps with a wiring harness adaptor that will give you positive and negative wires to connect the pump electrically. Most sellers of this pump just ship it with the socket and you have to find your own adaptor. The adaptor can cost up to $20 plus shipping by itself!

The Bosch Cobra Water to Air Intercooler Pump is designed for a 16 gauge wire, which this part has. Most connectors you will find being sold for this pump are fuel injector connectors with 18 or 20 gauge wire which may result in poor pump performance, voltage drop, or dangerously hot wires.

We are now taking pre-orders for the new and only custom highflow JRSC inlet.  Full production units are expected in about 6 to 8 weeks. First come first serve basis.

This unit is pre-ported to allow the use of larger OEM or aftermarket throttle bodies with our adapter plates.

Benefits:

• Ability to upgrade throttle body without having to use spacers, just order our simple adapter that matches your TB.
• Increased and smoother air flow due to its larger and direct path from throttle body to supercharger
• No porting necessary
• Hidden vacuum lines for a clean look
• Can easily be polished or anodized (additional costs apply)

Now with clearance for aftermarket fuel rails!

This product relocates the power steering to allow the use of the original Honda/Acura auto tensioner.

This improves belt tension at any rpm as the belt stretches at higher rpm levels.  PSI boost levels are increased and become steady and easier to tune.

Belt schredding is a thing of the past.  You will no longer need to adjust any tensioners manually.

Installs easily with just two additional OEM powersteering bolts and new belt.
