A. O.S. .12 TG (P) with 12D Slide Carburetor

Price : $235.00

This is the O.S. Max .12TG P On-Road R/C Vehicle Engine with 12D Slide Valve Carburetor and without Pull Starter. ROAR Legal. FEATURES: ABL (Advanced Bi-metallic Liner) This process uses a double layer of plating material rather than one thick layer. This helps the metal bond to the cylinder and is more durable. Also, the plating process is more consistent, resulting in a more precise fit between piston and sleeve for better compression, longer life. Pilot style crankshaft Two year warranty INCLUDES: O.S. Max .12TG P engine, 12D Slide Valve Carb, #8 glow plug REQUIRES: Car Blend Fuel: 20% nitro Air Filter (OSMG2384 or OSMG2360) Electric starter and exhaust system depending on vehicle Glow starter and track equipment SPECS: Displacement: 0.128 cu in (2.1cc) Bore: 0.543" (13.8mm) Stroke: 0.551" (14.0mm) Practical RPM Range: 5000-30,000 Power Output: 0.7ps @ 28,000rpm Weight: 7.45oz (211.3g) Crankshaft Size: 1/4-28 pilot-shaft style Distance between mounting holes same side: .43" (11mm) Distance between mounting holes opposite side: 1.24" (31.4mm) Distance/top of cyl.head to bottom of mounting flange: 3.03" (77mm) Height/bottom of crankcase to top of cylinder head: 3.54" (90mm) Width between mounting flanges: 1.53" (39mm) Width of crankcase beneath mounting flanges: 1.00" (25.4mm) Exhaust outlet, outer diameter: 0.55" (14mm) Exhaust outlet, inner diameter: 0.39" (10mm) Carb inlet, outer diameter: 0.63" (16mm) COMMENTS: Some points on Slide Valve and Rotary carburetors- Rotary carbs offer a larger response in the middle of the engine's power band. This is desirable for off-road applications where throttle response must be varied. Slide Valve Carbs provide greater response at the beginning and end of the power band. This works well for on-road and racing vehicles demanding fast take-offs and high speed.

B. O.S. .18 TZ (P) Turbo With 11K Slide Carburetor

Price : $280.00

This is the O.S. Max 18TZ Turbo Engine with Pilot Shaft and 3 needle 11K Slide Valve Carburetor. Ideal for on-road touring cars. FEATURES: Oversize case fins dissipate heat to keep engine temperatures lower Five port cylinder liner for increased air flow 12mm rear bearing lessens vibration and allows engine to handle more torque Slide valve, three needle 11K carburetor designed for on-road vehicles Super-hot turbo P3 glow plug for more power and improved fuel economy Rear exhaust, round port design Two-piece head design (inner head or head button and outer head) INCLUDES: One 18TZ turbo engine with pilot shaft, 11K slide valve carburetor, P3 glow plug, exhaust seal o-ring and instruction manual REQUIRES: Muffler (exhaust system) depending on vehicle Starting equipment Fuel: 5% - 20% nitromethane content Most of the fuels we carry meet or exceed the lubricant content required for maximum engine performance and long life. In the past conventional lubricant content used in fuel was 18%. But with new advanced technologies, fuels like Red Alert and O'Donnell have a better quality of lubricants even thought the percentages of lubricant content are lower. These high tech lubricants provide exceptional cooling and protection. SPECS: Displacement: 0.183 cu in (3.0cc) Bore: 0.629" (16.0mm) Stroke: 0.590" (15.0mm) Practical RPM: 3,000-34,000 Output: 1.8ps @ 29,000 RPM Weight: 7.8oz (222g) Distance between mounting holes same side: 0.43" (11mm) Distance between mounting holes opposite side: 1.2" (31.4mm) Distance from end of crankshaft to front bearing: 1.16" (29.5mm) Distance from center of engine to front of crankcase: 1.4" (34.8mm) Distance/bottom of mounting flanges/top of cylinder head:3.2"(81.2mm) Width of mounting flanges: 1.5" (39mm) Length of exhaust flange: 0.24" (6mm)

O.S. 21VZ-B (P)-T V-Spec w/21C Slide Carb

Price : $425.00

Competitors tend to stick with a winner and the 21VZ-B V-Spec-T (P) makes that easy to do. The raw power to exploit a split-second opportunity is there, tempered by the ability to fine-tune and finesse throttle control to the needs of different tracks and situations. And to help keep the 21VZ-B V-Spec-T (P) at the peak of its power, O.S. has given it a billet aluminum piston, hardened ABC sleeve for added wear resistance and a new crankshaft design that's simultaneously slimmer and stronger than any O.S. crankshaft ever made. The 21VZ-B V-Spec-T (P) designed for first-place finishes over the long haul from O.S. More power and durability. The brass sleeve is chrome-plated for performance and hardened to withstand the wear that racing action can produce. CAD-refined and CNC-machined ports smooth airflow and boost power. Track-tune in seconds! Increase control on low-traction tracks by inserting the 8 mm (red) or 9 mm (blue) carb restrictor. Takes only a second, but pays off, lap after lap. Features: Hardened, chrome-plated, 4-port, cylinder and liner for high durability and long life Machined steel piston features parallel rings that trap fuel oils and use them as a seal to enhance compression and boost power Reshaped crankcase core ensures smoother air flow and more consistent performance Slide Valve Carburetor with 8mm and 9mm Carb restrictors allow tuning to specific track conditions, Low-end Needle adjusts from side to side for maximum adjustment ease V-shaped two-piece turbo head design provides fast heat dissipation UPDATED: This is the updated engine with the new 21J carburetor.
