NOTE: Photography captured during NMRA Spring Break Shootout
It has been a red-hot month for Florida’s Yandro Ulloa and his Levin Motorsports 1998 Mustang Cobra and he can add the Stick-Shift Elite class win at the Texas 2K19 at Houston Raceway Park, Powered by Penzoil, to his list of victories.
It all began through the opening days of March with an action-packed weekend during the 25th anniversary Nitto Tire NMRA Spring Break Shootout, capturing victories in the TREMEC Stick Shift Shootout and Mickey Thompson Cobra/Terminator vs. GT500 Shootout. He followed the double-win by sliding into the Aerospace Components Winner’s Circle the following weekend during the NMCA Muscle Car Mayhem when he collected another Edelbrock Victor award for topping the Gear Vendors True Street class.
The clutch dust barely settled on his impressive 7-second machine when he loaded up the trailer for a trip to Houston, Texas from his hometown just outside of Tampa, Florida. Facing stiff competition, Ulloa and his crew of one—Joshua Levin of Levin Motorsports—turned up the twin Precision turbochargers and set the pace for the field with a 7.73 at 183 mph. On Sunday, during eliminations, it didn’t matter if it was an import or domestic car sitting in the lane beside him, Ulloa unleashed the fury of the 7-second Cobra and collected winning time slips all day long until he was the last man standing!
For those who are unaware of Ulloa’s combination, it is pure brute force with a Levin Motorsports built 281ci powerplant that wears a set of Precision 6870 turbochargers. The turbo kit began life as an On3 kit but has been modified to feed into a wild looking air-to-water intercooler that sits on top of the engine. There are also side-exit exhaust dumps for outlaw races and a custom exhaust that goes past the firewall for NMRA True Street competition. Backing the twin turbo engine is a TREMEC T-56 that was rebuilt by RPM Transmissions and a Black Magic clutch sits between the transmission and the engine. Levin Motorsports installed an AEM Infinity stand-alone ECU and tuned it on their in-house chassis dyno.
Adding to the legend and lore of Ulloa’s quick times and impressive consistency is his use of Mickey Thompson ET Street Radial Pro 275 tires, a very unusual tire choice as it is often considered a taboo practice for a stick-shift car of this caliber. All of the quick stick cars rely on a bias-ply tire to help absorb the shock of a clutch-dump. Ulloa worked with Levin Motorsports and High Revolution Fabrication and Performance (HRFP) to get the engine’s power management and the UPR/HRFP suspension working properly on the radial tires.
Ulloa has been a best of 7.67 at 184 mph at Palm Beach International Raceway during the That Racing Channel Street Kings event and that run is currently the quickest “stick-shift” car of any kind. To qualify for that title the vehicle must utilize an H-pattern shifted transmission like a TREMEC six-speed or similar box.
