Improved oil
drain tube clearance.
Our twin-ported wastegate now provides up to 50% more wastegate
flow. This results in better boost control for single turbo
applications as well as twin setups.
Our adjustable boost pressure regulators utilize higher spring
rates supporting higher pressures.
These actuators employ our new "Easy-Adjust" feature.
Borg Warner Low Drive Pressure turbine wheels. AKA, the “Killer
Wheel”
(71mm instead of the 65mm HTB2 wheel).
Factory 1-Year warranty.
The initial spool-up of these turbos might be slightly slower
than out HTB2 series turbos but since the turbine wheels are
low drive pressure design, they then build boost faster, offering
you quicker acceleration.
These turbos should also provide a couple hundred degrees cooler
EGT's under heavy acceleration and heavy
loads like towing.
Like our HTB2
turbos, this series uses high torque, extended tip compressors =
62mm/87, 64mm/92, 66mm/96. (Alternate compressor sizes are for comparison
to Garrett Powermax advertised compressor sizing.)
*A note about
compressor choices -Our 62 compressor is the best choice for
all around streetability / towing.
The 64 and 66 compressors are primarily competition compressors.
Approximately 10% of our customers have witnessed excessive "surging"
issues at lower RPMs (below 2000) and higher boost (above 20 PSI)
conditions when using competition compressors for towing or daily
driving.
