Hi,

This is my LDRXN "converted" to bar.
Can someone estimate a power and torque from this?
It is enough to achieve for example ~ 400hp&580nm?

440cc injectors
rs4 intercoolers
k03 hybrid turbos
rs4 clutch&pressure plate
pipercross air filter
max rpm 7000
2.5" downpipes
pre-cats&cats delete
2.75" resonated single pipe catback

rpm   boost
2500   1,24
3000   1,27
3500   1,30
4000   1,30
4500   1,30
5000   1,30
5500   1,26
5800   1,20
6000   1,19
6500   1,15
6800   1,05

No.

Log and use hp/tq calc or dyno.

Timing and fueling will have a significant effect on tq/hp

Not only that, but absolute hp/tq numbers from a dyno are actually meaningless anyway, they should only be used for measuring gains relative to a baseline reading.
