The Silver Surfer Mark III
The Silver Surfer has returned with a great new compressor wheel profile for the 2013-2014 year, after being in use for almost 10 years!
The Silver Surfer is a turbo in a size range that correlates with in the GT(X)3071R-GT(X)3076R Garrett mid-framed T3 footprint. At approximately 59lbs/min, The Silver Surfer gives 1.8-2.4 litre 4-cylinder and 2.5 litre 6-cylinder engine applications the ability to combine the responsiveness needed in the mid-rpm range with additional upper rpm range to reach levels of over 570HP (slightly higher than a GT3076R standard turbocharger) without the possibility of over-surge issues after 28psi of boost pressure, due to its enhanced compressor wheel profile, and well-matched turbine exhaust wheel and ported turbine housing in a T31 footprint.
With its T6 -7075 forged aluminum composition, The Silver Surfer has unsurpassed durability to prevent compressor wheel flex that is a typical issue with other "billet" aluminum wheels that are of a lower strength composition. As with all of the STC Forged aluminum series, this turbo gives the reliability, repeatability, and rebuildability that is expected from Genuine Garrett Products
This unit has a standard Journal Bearing T31 2.5" turbine housing configuration, which can easily replace the standard T3/T4 Garrett-based turbocharger, and is available in T3 or T4 3" V-band configuration. (T3 V-band is only available using our 2.5" 4-bolt to 3" v-band conversion flange )
The use of 3/8th NPT water fittings for the Journal Bearing version is optional, but highly recommended for those using this turbocharger for "daily driving" duties in which oil temperatures and pressures are put to the test.
The Ball-bearing version is optional for an additional charge, and requires the use of a restrictor (.030") and water fittings. *
This particular turbocharger is designed best for engine applications that generally plan to run efficiency ranges from 14psi-31psi that plan to run from 380whp-540whp in the standard T04b volute-ported compressor cover.
Please see the "Special Notes" tab to know which fittings are needed for the Journal Bearing & Ball-Bearing cartridges
The Silver Surfer comes standard with a T04B 2.75" inlet as the compressor cover, and .63 A/R T3 turbine housing. Other turbine housing A/Rs are highly discouraged as it changes the entire characteristics of the turbocharger. If there are questions regarding this please e-mail us.
All Journal Bearing turbos use optional water-cooling ports. These are not required for the turbocharger to work properly, but are highly recommended for optimal use.
Important Sizes and information to note:
Water Ports = 3/8NPT
Oil feed fitting size 1/8NPT
Recommended Restictor = .060"-.065" for oil pressures over 75-80psi oil pressure
All Ball-bearing turbos use required water ports in order to function properly, and share the same oil feed and fitting size as the Garrett GT and GTX series
Water Ports = 14mm
Oil Feed Fitting size = 7/16
Recommended restrictor = .030" for oil pressure over 22-40psi oil pressure
For both Journal Bearing and ball-bearing STC turbochargers, return flange is still 1/2 inch flanges used on T3/T4 turbochargers, not the GT Series
