Increased turbo Gt1446 for Fiat 500 Abarth

Oversized rebuilt turbocharger

Reinforced:

Turbo conceived and designed with a single goal RELIABILITY, given the excessive delicacy of the original GT1446 with its oil leakage problems, we decided to create an almost indestructible turbo but with an impeller diameter equal to the original in order to have the identical delivery and do not compromise the low revs with an annoying tubolag

Suction impeller size: 46 mm aluminum, with 6 + 6 blades

Exhaust impeller dimensions: 9 blades 41 mm

Rotor shaft: 7.88mm

Bearings: oil (bushings) with 360 ° shim as original

Geometry: Fixed

Suction nut: original

Exhaust nut: original

Structural pressures: 1.6 bar maximum peak and 1.4 bar with limiter

Test: balancing up to 165,000 rpm and dynamic flushing on the bench

CV test: 210 hp

RPM needed for 1.0 bar: about 2100

Lag value: 2300 rpm

Minimal contour processing: ECU Programming, Sports Air Filter

White Series:

Designed for those cases in which the control unit has already been remapped but the original turbo becomes unreliable, by installing a larger impeller, the operating revolutions are reduced and therefore the risk of overspeed, one of the main causes of breakage of a turbocharger when performing elaborations only at the level of the control unit without adjusting the turbo.

Suction impeller size: 49 mm aluminum, with 6 + 6 blades

Exhaust impeller dimensions: 9 blades 43 mm

Rotor shaft: 7.88mm

Bearings: oil (bushings) with 360 ° shim as original

Geometry: Fixed

Suction nut: enlarged to accommodate impeller with larger inducer, polished and optimized the air outlet from the nut, improving flow and avoiding rising temperatures

Exhaust nut: enlarged, polished and optimized the exhaust gas outlet such as to reduce internal counter pressures and favor the flow so as to dissipate temperatures with an evident increase in power and reliability

Structural pressures: 1.6 bar maximum peak and 1.4 bar with limiter

Test: balancing up to 165,000 rpm and dynamic flushing on the bench

Test hp: 225 hp

RPM needed for 1.0 bar: about 2200

Lag value: 2500 rpm

Minimal contour processing: ECU Programming, Sports Air Filter

Yellow Series:

The most requested of the three versions thanks to its versatility to any driving style, good reactivity already at low levels, without departing so much from the turbo of the original turbo, offering always increasing power at all engine speeds. The increases made and the design of the impellers allow an excellent result between reliability, resistance and performance

Suction impeller size: in avional 55.39 mm, with 6 + 6 blades

Exhaust impeller dimensions: 9 blades 44.20mm

Rotor shaft: 7.88mm

Bearings: oil (bushings) with 360 ° shim as original

Geometry: Fixed

Suction nut: enlarged to accommodate impeller with larger inducer, polished and optimized the air outlet from the nut, improving flow and avoiding rising temperatures

Exhaust nut: enlarged, polished and optimized the exhaust gas outlet such as to reduce internal counter pressures and favor the flow so as to dissipate temperatures with an evident increase in power and reliability

Structural pressures: 1.7 bar maximum peak and 1.5 bar with limiter

Test: balancing up to 165,000 rpm and dynamic flushing on the bench

Test cv: 240 cv

RPM needed for 1.0 bar: about 2400

lag value: 2700 rpm

Minimal contour processing: ECU programming, free exhaust, increased injectors, intercooler and sports filter

Red Series:

The most performing of the three, in effect a larger turbo designed and studied to express the maximum starting from the original turbo, the increase carried out by the compressor to the turbine creates a flow without back pressure and without temperature increases on both the exhaust and intake side of the engine this allows to reach unthinkable powers for an original turbo, moreover with great study on test benches and cars we were able to create a design of the impellers that would give us all the power we had set for ourselves but without having a too slow response (turbolag) but a good reactivity already from 2900 rpm onwards.

Suction impeller size: in Avional 59.97 mm, with 11 + 0 blades

Exhaust impeller dimensions: 9 blades 44.20mm

Rotor shaft: 7.88mm

Bearings: oil (bushings) with 360 ° shim as original

Geometry: Fixed

Intake nut: enlarged to accommodate impeller with larger inducer, polished and optimized air outlet from the nut improvesndo the flow and avoiding the increase in temperatures

Exhaust nut: enlarged, polished and optimized the exhaust gas outlet such as to reduce internal counter pressures and favor the flow so as to dissipate temperatures with an evident increase in power and reliability

Structural pressures: 1.9 bar maximum peak and 1.7 bar with limiter

Test: balancing up to 165,000 rpm and dynamic flushing on the bench

CV test: 265cv

RPM needed for 1.0 bar: about 2600

lag value: 2900 rpm

Minimal contour processing: ECU programming, free exhaust, increase exhaust line diameter, sports air filter, increased injectors, intercooler

What is Avional?

The A2000, (trade name Avional), is a high-strength aluminum, or aerospace material with a light specific weight, you have absolute certainty of the mechanical properties of this material. The main alloying element is Copper, in some alloys there are additions of magnesium and manganese. These alloys undergo mechanical processes that eliminate those oxidation defects (mostly silicone) and guarantee the granular structure of the alloy, improving the properties of the material under stress, in fact, after heat treatment they develop mechanical characteristics comparable to those of carbon steels and improvements are also to be recorded in terms of duration. In other words, they are to be considered more resistant than traditional impellers.

Technical features

The MFS impellers are made on high-speed 5-axis CNC machining centers, speeds necessary to reach the high profile given by aerodynamic blades that guarantee high level mechanical performance. This also means that the geometry of the wheel is not subject to the tolerances of the mold and to the variability over time of the casting processes. Basically we are talking about zero compromises during the complex processing of the blades. In this process, the best and most modern technologies in terms of metrology and measurement are applied, in order to inspect the geometric thickness and tolerances required according to the requirements of the engineering specifications of a modern turbocharger.

Benefits
Increase in the air flow
Response in less time (Turbolag)
Performance increase
Longer duration

Our oversized turbines are developed with two fundamental criteria clearly making it more performing but above all trying in every way not to compromise reliability but we even set ourselves the goal of increasing it and that is why despite being a modified turbine we guarantee the product for 12 months.
So if you are looking for a turbo to give your engine a little more life without the risk of continuous breakdowns both to the engine itself and to the turbo this is for you.

CentroMotoriTurbo is a company made up of technicians specialized in the sector. We therefore offer targeted and specific technical assistance, both before and after the purchase, completely free and without limits.

The oversized turbos are created on request, so from the moment of the order they need 5/15 working days for shipping

For those who decide to return the old turbo, it will be withdrawn early, when the increase is completed.
12 Months Warranty
