51/R Turbocharger

We've updated and improved this turbocharger throughout with a revised compressor wheel that improves transient response and boost threshold characteristics, optimized for low-medium range pressure ratios. Compressor efficiency at righ RPM is also improved with peak efficiency centered exactly where they are needing on most 2-2.5L engines. The existing high pressure version is still available upon request.

All-new 9 blade 52mm Turbine wheel perfectly matches this new compressor, and offers similar response to the existing 47mm turbine wheel, hower with improved power capabilties at high RPM.

Optimized for 1.8-2.5L displacement engines with power outputs between 300 and 525BHP, the 51/R turbocharger is well suited to many high performance modern engine applications.  It's 51mm compressor inducer supports flow rates of 50 lb/min, while also providing impressive surge resistance for a wide flow range; critical for correctly matching the high volumetric efficiency across wide RPM ranges seen with today's modern 4 and 6 cylinder engines.

Optional compressor shroud designs further increase compressor map width, while also improving compressor efficiency closer to surge, resulting in impressive spool characteristics and low to mid range engine torque output.  Based around a patented and fully serviceable ball-bearing cartridge featuring second-to-none materials selection throughout, this turbocharger is built to last even under high temperatures and rotor speeds.

A wide range of turbine options are available, allowing for a perfect turbine match under virtually all operating conditions within this power range. The serviceable and modular nature of the CHRA design, in conjunction with our commitment to customer satisfaction and product adaptability allows for repair, modification, or upgrading of your turbocharger at any time, without the unnecessary re-purchasing of a entire new unit.

All of our turbochargers are built to order to meet your exact requirements and specifications.  Our current lead time is 2-3 weeks. Please email info@spectrummotorsportssolutions.com for more information.
