After 3 months of being broke it is fixed 16psi on stock engine and 11.2-11.5 A/F it did 410 to the ground, probally could get somemore power by leaning it out but it is safe and that is what I wanted, over 400hp to the wheels and a safe A/F. T-78 is awsome I can't believe how fast it spools up. Any way just thought I would share this with everyone.

 

Good numbers!

Whats your timing at during the 16psi run?

Whats the AR on the T78?

Now, you just need to turn up the boost.

timeing was 17, and I'm sorry AR? do you mean the size of the AR housing. thanks

 

16 psi/stock ports= 400 rwhp! nice!!!!!!


i agree the T-78 spools quite fast considering its size..hey mitsu turbos are known for this

 

1.0 A/R

 

Any chance of you posting your maps?

You've got the same setup as me, and I'm stumbling around in the dark trying to learn how to tune...

 

when you say stock engine do you mean no porting or aftermarket seals?

 

no port work and factory seals so the boost will stay at 16psi for a while. And I am willing to share the maps. POWER AXLE When I get ready will you port and do my seals ?

 

Woohoo! Looking forward to the maps, then. I have yet to see a PowerFC map for a T-78. None of the other maps seem to come anywhere close what the turbo needs.

Don't forget the PIM voltages, too.

 

Goblin-If I give you these maps it is just to get you in the ball park it will still need to be finley tuned for your car,you need to get it on a dyno and check your air fuel ratio before you start turning up the boost. You are playing with a grenade so becarefull , also list your mods for me so I can compare them Oh yea check your PM

 

Yeah I know. Getting to the ballpark is exactly what I'm trying to do right now. I keep upping Basic Fuel Injection Correction values in the PIM settings and slowly raising the boost while watching the EGT and the J&S/A:F. I'm to the point know where I can run a whopping 0.75kg/cm^2. It's getting there (I was only running 0.6), but it's slow going.

Relevant mods follow:

GReddy T-78 kit (headers, hot end of the turbo, and downpipe ceramic'd, downpipe thermal wrapped)
GReddy wastegate (spring cut to allow 0.6kg/cm^2)
GReddy FMIC
Worked 550cc primaries and 1300cc secondaries
RP fuel pump
Adjustable fuel pressure regulator (I forget the brand and base setting, but it's adding 1:1 at the moment)
Apex PowerFC w/Commander
Jacobs Rotary ProPack
