ATP implements
the Garrett GT42 on the MKIV Toyota Supra engine!
Another example of modern "GT"
aerodynamics blowing away old "T" technology!
Fuel:
-Dual In-tank pumps
-Dual -6 AN fuel lines
-Aftermarket Dual Feed Fuel Rail
-Adjustable 1:1 Aeromotive Fuel Pressure Regulator,
-750cc injector
-Stock ECU w/ VPC & GCC Piggyback.
Implementation:
Old "T" Turbo: T72 Compressor,
.70 A/R Turbine housing
New "GT" Turbo: GT42 Compressor-94mm,
1.06 A/R Turbine housing
Application Notes:
On the T72, it is common practice to run a smaller A/R
such as .70 in attempt to keep this large turbo "streetable".
Many T72 users may cringe at the thought of running an A/R larger
than 1.00 on a turbo for a street application. Amazingly, the
much more HP capable GT42, even with its larger wheels and much
larger 1.06 A/R, is capable of spooling up just as well as the
smaller .70 A/R T72 in the low RPM while far exceeding its peak
HP potential, thanks to modern aerodynamics and better turbine
efficiency. The technology found in the wheel combinations used
in the GT series turbocharger is decades ahead of the obsolete
T turbochargers. This application is another example of how old
turbo/wheel/A/R sizing habits can be overcome with new technology!
Look for additional exciting
test results from the Ball Bearing version of the GT42, called
the GT42-R and the 1000 HP called the GT42-RS!
