I've been searching for a compressor map for this turbo but have been very unsuccessful in finding one. Does anyone have one?

Thanks in advance.

 

Let me know if you find it! I haven't been able to find it either!!
Thanks

 

Here is a T76 Compressor map... All turbo's which are designated as T76, will have this compressor map as a baseline.. Ball Bearings will and
the compressor housing will make a difference in efficiency on the outer edges of the compressor map.. However, this map
still specifies the basic Island of all T76.. Any changes to this Island, and the turbo is no longer a T76... So use this map
for all your calculations.. The big difference will be Ball Bearings or Non Ball Bearing.. Anti-Surge Compressor housing, and NON Anti-Surge Compressor housing..

However the ball bearings will determine the time to full boost and consistency of airflow, while the Anti-Surge housing will stretch the edge of the map to the right
once the engine reaches the edge of the map.. But in general, this is the basic T76 compressor map..

Also, there is also a possible variation on the Turbine wheel.. However, this does not effect the compressor map.. Longer tips or Shorter tips, and lighter turbine wheels
promote better efficiency based on back pressure as boost is increased.. Some turbine blades can run more boost without drastically increasing pre-turbo pressures, based on turbine wheel
design... Most changes to a T76 Turbo by different manufacturers will work on the turbine side of a turbo to promote different characteristics.. Use an anti surge housing to
show better gains on the edge the standard T76 map below..

No problem!

Thats a badass turbo! Gonna make big horsepower with that one! Spools fast too!

 

I just had it rebuilt at Precision, That is my old one (maybe 75miles on it) that i don't need.
Replaced with GT4788 not as easy to spool w/281ci. In a test pass we ran 9.0 @ 161. and it has plates on it!!!
Get it STREET CAR

 

Any pics of your setup?

 

Sweet! Sounds like you got her spooled up nicely before launch.. How many pounds of boost did you launch with to run that 9.0 ET?

Also, x2 on a pic of the engine bay, with the GT4788!

 

We leave on trans.brake with 4.8lbs. We are running 275-60-15 MT Drag radial. (8.9" tread).
It already breaks loose all the way past 100', we also loose traction past 1200' @ 155mph! Need to put in e-boost controller.

Very Nice!
like the Dizzy a lot!

 

When I went to open up your pic it vanished!

What size is your inlet pipe and throttle body?
My 3 1/2" and 105mm throttle.
Also are you A-A or A-Water?
Mine is A-Water, put intercooler(1500hp)behind bumper. At the time didnt want to cut holes in car!
Car needs 2500hp cooler so now it has to go into car!!!! Would have saved time and $ if just
put in car!
