gt3071 @ 1.8 bar what BHP?

[Quattro Dan.]

Now i have re built my engine with scat rods I am going to get it mapped to achieve its full potential.

It is currently mapped to 1.4 bar and the tuner has suggested to increase this to 1.8 bar. How much BHP roughly will 1.8 Bar give using a GT3071, RS2 EM, 044 fuel pump, apple green injectors, Milltek, No cats. etc.

Thanks, Dan.

I had around 420hp running same setup with 2bar overboost and roughly about 1.7 at the redline.

Ditto....

Dimitri and Hoffer ran a 3071 to the max Is that 1.8 bar at the red line or mid range? Power should be between 6&7 k so that's where the boost value will affect bhp rather than torque figure...

Forgot to add I was on the small AR(0.63)

0.82 A/R, 2.1 bar in middle and 1.8 to redline with slight boost leaks gave 430 bhp and 610nm on the MRC dyno on an otherwise stock RS2 engine (apart from fuel pump and injectors).
I think it is possible to get to 450 if the compression ratio is dropped sufficiently.

prj i thought the 0.82 a/r was good for around 540hp?

No. That's the GT3076R. You may be refering to the GTX3071 which is capable of above 500hp

one quick question,what about the green injectors?are they running maxed out with 3071 @ 1,8bar on pump gas?

I have 2871 @1,8bar on E85.it's already maxed out passing 5.5K rpm.i'm still waiting the chance to get the top head

rebuilt and order the deka injectors at the same time.my guide valves are worn out and leaky the hell boost out.
