Same BHP but high NM?

Re: Same BHP but high NM?

Just curious and new to tunning world... I have just tune my n55 engine from 4xx torque to 6xx torque!! Horsepower from 3xx to 4xx...

To me it looks impossible but the printout says so ...

Any gurus can enlighten ?

Yes you can have high torque and low bhp. Turbo charged engine with high torque at low 2-3k rpm and restrict the max rpm which will restrict the max hp.

If dyno says 400+nm torque and 300+hp at stock...that means it was corrected by some factor and inflated.

The 600+ torque is probably peak torque and just for segment of rpm range at mid range. At higher rev, turbo boost should drop...

Show the chart...

335 on n55 can produce such torque?? I can't believe it

I ran those specs before any hardware upgrades !!!

After that I switched to JB3. With the necessary hardwares, it was running 620 NM and 420 horses. But, watch those wastegates.

Ask RBB what his monster is running on now...

Any higher number, if not from a happy dyno, will strain an unhappy gearbox, esp if DCT.

Agreed with kenn.

Those numbers are awesome , better suited for manual ba . DCT or ZF sure very stressed on those figures
