O.S. Engines
Check out the Dyno Test Review written by RC Nitro's Steve Pond.

.18 TZ
The most powerful small block engine on the market!

Premium power for the serious racer!

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

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.

 

inset 2

The oversized, 2-piece turbo head produces tremendous power, and is simpler to maintain as well.

 

inset 3

The 18TZ features a more efficient rear exhaust port design that boosts power and rpms.

New small, compact pull start!
