 For today's competition driver, turbo is the way to go...and no other turbo engine goes like the 18TZ from O.S. It outperforms all other .18-size engines, delivering race-winning “outlaw” power for 1/10 scale buggies, stadium trucks and touring cars.
In a recent dyno test for an upcoming issue of RC Nitro Magazine, the new O.S. 18TZ rear-exhaust engine cranked out a record setting 2.28 bhp at 30,500 rpm. Steve Pond, R/C Nitro magazine
- Oversize fins on the case dissipate heat to help keep engine temperatures lower.
- Five ports in the liner increase air flow for more power.
- The rear bearing is 12 mm in diameter, which lessens vibration and allows the engine to handle more torque.
- A super-hot turbo P3 plug is included for better burn, more power and improved fuel economy.
- The 18TZ-TX version features a new compact recoil starter that's smaller and lighter, making it easier to install.
- The slide-valve operation of the 3-needle 11K carb is designed for on-road vehicles; off-roaders will benefit from the 11L rotary carb with two needles.
- The oversized, 2-piece turbo head produces tremendous power, and is simpler to maintain as well.
- The 18TZ features a more efficient rear exhaust port design that boosts power and rpms.
