TPC has developed a Stage 2 turbo that directly competes with the performance of the well known Pure Stage 2 without the hefty price tag.
Attached bellow is our Stage 2 dyno graphs on MS109 race fuel which made a consistent powerband with 530whp. The other one we will post shortly, it was done on 93 oct pump gas with small boost leaks and made 450+ to the wheels with a OTS map.
This extremely similar power was done with a smaller compressor wheel then the Pure Stage 2 while both using the same turbine wheel. This means the 58mm turbine wheels are maxed out no matter how big the compressor wheel is. Bigger isn't always better..
TPC Stage 2 compressor wheel inducer: 59mm
Pure Stage 2 compressor wheel inducer: 62mm
Both use the same 58/59mm turbine wheel
All our upgraded N55 turbochargers come with a new revised waste gate bushing assembly and a new vacuum waste gate actuator. We off the same upgrade for EWG set ups.
Please put in the notes if you require a EWG turbo upgrade or vacuum upgrade.
