Description

Peterson Fluid Systems is proud to make one of the best performing and most versatile oil pumps available in motorsports. The R4 Oil Pump is the result of more than 50 years of fluid engineering and racing experience. Peterson pioneered the twisted lobe rotor design to deliver solid oil pressure, even in high temperature low viscosity oil set-ups. Its scavenge sections pull serious vacuum too. Peterson provides heavy-weight performance without the heft: shallow depth screw-in fittings, profile machining, and aluminum rotors makes the R4 one of the lightest pumps available. The pump's steel drive shafts are 5/8 in. diameter with a 3/16 in. keyway to receive an appropriately sized pulley or machined with a 3/8 in. male hex for cam or accessory drives. R4 pumps have a rear drive provision which allows for the direct mounting of many popular drive accessories like fuel pumps, vacuum pumps, or power steering pumps with the appropriate adapter. The most decerning engine builders trust the R4 Oil Pump to protect and extend the working life of their engines by having the proper pressure with the proper volume at the right time. Maximizing horsepower with the pump’s ability to create crankcase vacuum as it scavenges and reduces windage in the oil pan. Equally at home on a 5 second drag car, endurance racing at Le Mans, punishing deserts of Baja or even at the local dirt track, Peterson has an R4 oil pump to ensure a first-place finish in any race. Proudly made in the USA, all pumps are machined, assembled, and tested in house, in Longmont, Colorado. Custom configurations are available, contact the Peterson Fluid Systems sales and customer service team for additional options.

Testimonials

Looks like I get to be the first review for these guys. Let me start out by saying that I have had 3 other cars of a similar caliber to my GTR serviced/worked on and upgrades installed at other shops and none took the pride and level of detail that these guys did. I wish I could see all the welds on the downpipes and exhaust because it looked like artwork. Their fabricator made sure to send me daily updates and pictures which was also a big deal to me. For being an out of state experience it made it seem more like they were local to me and that I had known them for longer.

Took the leap of faith on buying a set of their R35 intakes and downpipes because the price was half of anyone elses plus their car hauls a** at the track. Install went smooth and the power seems to be even better than advertised. Cant wait to get tuned in a few weeks. Their shelf tune honestly has to be 600+ hp as I pulled on a Hellcat last night. I see these guys and gals going a long ways if they can get out there and advertise. Customer service is on point paired with BIGGG savings for the winning combo.

Bought a Motec and had these guys build the harness and set it up fully. Track car that received the level of attention and detail of a show car while here. Made me feel at home every time I popped in for a visit and always offered to buy me lunch/dinner. I don’t see me shopping anywhere else as they make you feel like your family.
