RONNIE ANDERSON’S RZR RS1

Inside the two Texas Outlaw race winners

RONNIE ANDERSON’S RZR RS1

Ronnie Anderson won the first two Pro NA 1000 rounds of the 2021Texas Outlaw UTV Race Series in his HRP/WER RS1. He was on the podium four more times in eight rounds, won the ninth round, and went into the double-header finale with a six-point lead over Kainan Baker for the $30,000 championship. He also stopped the Miller brother domination of the Pro Turbos by winning the seventh round in his hybrid XP Turbo S with the Pro XP engine, transmission and CVT, which we featured in the April 2021 issue of UTV Action. Anderson rebuilt that LOORRS-winning and points-leading Turbo for Texas and gave it a new wrap. Here are the mods done to his two race-winning RZRs.

HOLZ RACING SHORT-COURSE TURBO S PACKAGE

Holz Racing Products (HRP) has complete Short-Course kits for the Polaris RZR RS1, XP Turbo, Turbo S, XP1K and now Pro XP starting at $12,400. HRP Polaris Short-Course kits start with a Tig-welded, 1.75-inch, 4130 Race Cage, including an aluminum winged roof, full doors, aluminum fire walls, bed-delete kit, lowered seat mount, aluminum dash, billet steering column, window nets, radiator relocate kit with twin-fan CBR radiator, and number plates. The kit also includes heavy-duty radius rods and tie-rods, trailing arms, A-arms, and a front bumper with integral torsion bar, trailing-arm guards, an adjustable rear torsion-bar kit, nerf bars, a WORCS rear bumper, and a billet motor-mount kit. Inside, it includes a Joe’s 14-inch dished steering wheel, three-bolt quick-release steering hub and 1-inch spacer, plus a Yuasa sealed battery, a Sparco seat, and a 3-inch Master Craft safety harness.

K&T Performance fabricated the RS1 racing exhaust, and the K&N larger oval air filter and intake tract are shielded from the exhaust heat with two DEI heat barriers, with the gold one forming an open-ended box around the filter.

Anderson upgrades to CMI rear knuckles, hubs, and a big-brake kit, plus Wilwood calipers. His Velocity shocks have a Kashima coating on the shafts, and he runs CMI rear axles.

 

Ronnie uses the Sparco Evo seat ($850 separately) and a five-point harness, but he runs CMI tie-rods instead of HRPs. Being a Walker Evans Racing (WER) athlete, Ronnie uses the optional WER 2.5 Velocity shocks ($3600 through HRP) with a second reservoir on the prototype rears and 15×5.5-inch Legend forged-aluminum beadlock wheels ($550 each). For Texas hard-pack dirt, he runs BFG’s P285/75×15 light-truck T/As. Other options for the HRP RS1 and Turbo S Short-Course kits that Ronnie uses are CMI billet hubs ($779.80) and heavy-duty wheel studs ($299.96), an HRP billet shifter ($119.95), and an HRP-designed wrap ($1000).

Stock-length HRP A-arms have larger tubes and more gussets for strength, and the race build front bumper integrates HRP’s front torsion bar that must be used with the A-arms. A 3/16-inch aluminum skid plate protects against roost and nose-down landings.

 

Ronnie is running prototype Velocity rear shocks with second piggyback reservoirs on his Texas RS1 (this photo is of his Pro XP); the smaller one on top provides more plushness for hooking up on the blue groove, while the larger one works with the needle valve in the main body to prevent bottoming.

 

MORE SHORT-COURSE ARMOR

Ronnie has CMI Precision driveline and braking armor on both RZRs. Ronnie uses CMI big-brake rotors along with CMI hubs, but he upgrades to Wilwood twin-piston hydraulic brake calipers on all four wheels. Ronnie prefers CMI axles over the optional $2,900 RCV Pro Series II axles available through HRP. Call CMI for prices. Ronnie also uses HRP’s intercooler radiator with separate controls for the dual fans. Race rules require a fire extinguisher; HRP’s quick-release mount is $79.95, and the extinguisher is $50.

Anderson’s hybrid Turbo S with Pro XP power train was featured in the April, 2021, issue, and it has gotten some upgrades since narrowly losing the 2020 LOORRS Pro Turbo title. Check out the air scoop on the right side of the dash.

 

RACE-WINNING AND POINTS-LEADING POWER

K&T Performance did the tune on Anderson’s #52 RS1 and #752 Turbo S with Turbo Pro XP engine, clutch and transmission. K&T has Dynojet Power Vision 3 tuners for most UTVs for $399.99, and the Stage 2 Power Package with clutch springs and weights is $649.99. Stage 3 with a high-flow reinforced charge tube for the Turbo is $999.99; racers have reported collapsed OEM charge tubes on the Pro XP, especially in hotter weather. K&T fabricated the RS1 Pro XP exhaust and carries HMF, Gibson and MBRP systems for most UTVs for $430–$899.
