HELP!! WHAT BOOST WOULD A T28 HYBRID RUN??
What boost would a T28 turbo hybrid by Turbo Technics (360° bearing)fully rebuilt run been told you can only run 20psi max is this about right
Have a t3 fitted at the moment but want to put a smaller turbo back on as rouse cars had.
I got 320bhp at the moment but don`t really want to loose power would a T28 hybrid 360° bearing give me the same BHP as a normal T3

Cheers doug
cossymad wrote Don't know about safely, I think it's down to the limited fuel supply from the EEC4 brain.
I run at about 22-23psi over that and it does n't like it.
cossymad got 303bhp on a small turbo

My T28 can run more than 23 psi, but due to fuelling issues I don't want to.
It has hit atleast 26psi before, but again I am not willing to run lean to test psi of T28.
Mine is;
T28
360 bearing
Nissan sunny GTi-R compressor wheel
Cut back blades on exhaust side.
-31 actuator
New turbo 2 years ago. Still running strong, no smoke

a few more Q
what torque did yours make
Before cams it was 287 bhp / 303.7 lbft@ 3350rpm
After cams it was 303.8 bhp / 297.3 lbft @ 3440rpmwhat revs can you feel the turbo starting to pull at
It comes in at around 1250 rpm and is on full boost @ 3000rpmish been told thet run out of puff at higher revs true or not
True. I think at around 5750rpm it has stopped pulling although still boosts to 22-23psi @ 7000rpm

cossymad, I've been looking at the Apexi Super Fuel controller. It's supposed to change the voltage coming from the MAF to the ECU so that the engine can get more fuel. Have you thought about doing this?

The fuel pump really is on it's limit, as are the injectors.
What I am going to do next year is run either piggy back ECU running 4 additional injectors in tandem with the standard ones or using a HKS AIC (Addition Injector Controller) to run 4 green sized injectors and boost the fuel
