Turbo Loba LO400 ; information about pressure for RPM at many range.

Dany87

Hi guys ; i need to know one information:

I have mounted on my TTS stage 2+ the turbine loba LO400.

On the dyno test i have run only 351 Hp and 522 Nm (see attacched photo)

for have this power i have this pressure turbo:

turbo pressure Peak : 2 bar

turbo pressure at 6.000 rpm : 1.45 bar

turbo pressure at 7.2000 (limiter) : 1.25 bar

I ask those who have this turbo if you can tell me if it turns more 'or less in these pressure or if pressure turns to more' high and has 400 hp rolled those that sell this turbine

I repeat my car is a stage 2+ with this upgrade : exhaust complete ; big intercooler ; WG forge ; induction kit with cone ; Autotech fuel pump.

thanks in advice and sorry for my bad english

When i get on a Dyno i will get my results. But according to my tuner i got 1.8 Bar boots Peak and 1.45 to 1.4 Bar boost on the upper RPM range should be 380 hp / 500nm at the crankshaft. On Stock Turbo with 90/76 mm Downpipe,Autotech fuel pump, Big Intercooler and K&N Replacement Filter. But i got an 102 (ROZ) Octane Map. As my Tuner told me the 2.0 TFSI engine really depends on good fuel.

Hi Danny,

few infos that might be interresting for giving a statement:
- what fuel did you run?
- different spark plugs installed?
- exhaust diameter? Race cat or decat pipe?

1.2 bar in limiter is not enough for running 400 "real" hp. I think your result ist good for the pressure you run. Torque and hp is okay and your graph also looks good :daumenhoch:

For giving a correct reply on your request, the additional infos I asked you for would be great.

Cheers,

i run only with 100 RON shell V-power
spark plug installed are this : NGK PFR7S8EG
full exhaust 70mm with decat pipe

Do you have the possibillity to scale you exhaust back pressure? Screw out the after cat oxigen sensor, install a bolt with a pin to mount a boost sensor and check the boostof the exhaust gases in your system.
I don't know the construction of the exhaust, but maybe you run with several compensations that raise your backpressure up.
Alternatively, do you have a OBD tool lig VAGcom or a similar one? So you might log the programmed ignition. Step by step we might find the issue

The Power curve is low but doesn't look unhealthy (bad combustion, misfire, or fuel cut).
But the power is almost equal from 4500 Rpm to 7000 Rpm.
And the torque is going down regularly.
In an engine, power depend on air flow. So if the power stay even through the rev range, that mean that airflow remain the same through the rev range.
If the air flow can't grow through the rev range that should come from air restriction.

You should record :
Boost pressure (Specified)
Boost pressure (Actual)
Wastegate (N75) Duty Cycle %

If BP Actual is significantly Lower than BP Specified and N75 is close to 100%, that mean air flow restriction.
