— What makes the champ’s X3 so fast? —

Corry Weller won the 2018 Lucas Oil Off-Road Racing Series (LOORRS) Production Turbo UTV championship in her Weller/DragonFire Racing Can-Am X3 X rs Turbo R, and she is leading the 2019 Production Turbo class after four rounds with three wins. She is also the defending champ in Lucas Oil Arizona Regionals and is three points out of the lead for 2019. Weller also won the 2017 Weller Racing SR1 title and the 2017 Arizona Production 1000 #1 plate in a Yamaha YXZ1000R. She was second to Dustin Nelson in the 2016 Arizona Regional Production 1000s. Weller racked up all of those championships and race wins at the wheels of UTVs built by her husband Jason. We met up with the Wellers at the Estero Beach Battle South of the Border LOORRS rounds in Baja, where Corry won her third straight 2019 round but broke a wheel in the fourth round.

Corry Weller is defending her Lucas Oil Off-Road Pro Turbo championship in her Weller Racing Cognito Maverick X3 X rs Turbo R, which is set up for maximum cornering and handling on tight courses.


Jason built Corry’s 2018 championship X3 Turbo from the ground up and continually adds technology as he preps the UTV for each race. Rather than go with an unknown for 2019, he updates and upgrades the now #1 Turbo as he learns the car. Jason also races but postponed his racing career to also build Brock Heger’s #1 Yamaha YXZ1000R, which is leading Production 1000 UTV points for 2019.

An AiM MXS Strada digital dash logs lap times, and the full-color 5-inch display can be customized to show streaming data from the ECU. See Corry also uses a PCI radio to get information from spotter Jason and race officials.

Jason fabricated the racing cage, rear bumper and aluminum shroud for the CBR radiator and intercooler at the Weller Racing shop. He also added trick right-rear inner CV and outer rear CV guards to prevent rock damage, along with the front push bar/tow loop per LOORRS rules. Weller Racing’s Maverick X3 short-course seat base ($130.10) is made of 4130 chromoly and lowers the driver’s seat while still allowing adjustment. It’s made for the Sparco Pro 2000 LS seat ($720), which has a special non-slip fabric and is FIA approved. Corry uses a DFR harness and Sparco steering wheel.

Jason Weller fabricated the cage, bumpers, nerf bars, and aluminum housing for the CBR radiator relocation kit and intercooler. He also built the X3 exhaust using a Magna Flow muffler.

Suspension was upgraded with Cognito X3 X rs boxed upper A-arms, oversized tubular lower A-arms and trailing arms. Jason replaced the OEM Fox Podium IBP shocks with Fox RC2 2.5/3.0 Podium non-IBP shocks and re-valved them for short-course racing. WR also replaced the radius rods (N/A) and rod plate ($136) and the front ($136) and rear ($135.09) sway bar links with WR billet links. During practice and qualifying, Jason revised the front preload and cross-over settings to help Corry get over the rhythm section smoother, and he rechecked front toe after the changes. He later changed the secondary (Eibach) springs on the rear, and Corry won the main.

The X3 X rs is set up low for cornering, and the Cognito OEM-replacement suspension arms are more for armor than longer travel. RC2 shocks replace the OEM IBP units and have Eibach springs and Weller Racing valving.

The OEM axles were replaced with Demon Powersports’ X-Treme duty axles, which are $379.05 each. Weller fabricated nerf bars for the #1 X3 as well. In the first practice, Corry ran 27-inch Maxxis Ceros tires on STI HD beadlock rims. They switched to lighter Hoosier dirt-track tires for the second qualifying practice so she could get through the rhythms better, and she was a half-second faster than the Turbo field.

The Sparco Pro 2000 seat has a Weller Racing short-course seat base and DFR harness. Rugged Radios supplies clean air to her helmet.


Per LOORRS rules, the engine, transmission, and CVT are mostly stock. Boost is limited, so there was no reason to go with WR Dynojet High-Flow injectors ($499.99). Jason fabricated the exhaust using a Magna Flow muffler, re-flashed the ECU and added an AIM Sports MXS digital dash. Jason also retuned the stock CVT primary and secondary with springs and weights. The stock CVT ducting is retained, while the clutch cover got the WR quick pin kit ($79.99) for faster belt changes. WR sells the EPI severe-duty drive belt for $134.95. The WR X3 transmission seal guard is $49.99. K&N’s X3 air intake kit ($649.95) replaces the Donaldson-style air box with a free-flow filter and aluminum intake tubes. It increases power by 7.15 horsepower and improves throttle response. It’s not legal in 15 states and is intended for racing only.

Check out the cool roost deflector for Corry’s inner CV. There are also ones on the outside to protect rear CVs, brakes and wheels.

Following her third straight win on Saturday, Corry was running second on Sunday when she suffered a freak wheel failure and DNF that main. Second-place points holder Ronnie Anderson wasn’t able to capitalize on her misfortune with a top-five finish, so Corry still has a comfortable Production Turbo UTV points lead. Stay tuned for a feature on Brock Heger’s WR YXZ1000R, which leads Production 1000 UTV points by eight after wins in three of four rounds.
