As I understand it the torque figure is more important than bhp, at over 1000nm I think that's impressive

Correct this is my daily vehicle as i have a m2c thats stage 3 soo i asked more for torque then bhp and it flys from 50mph to 150mph

[@bartselter5332]

100%! It’s all about torque with these diesels. Also, bhp is pretty much just the equation Torque x RPM / 5,252. (To get a rough figure). Props to DSD. Great content, and the video’s have an awesome vibe to them. Wish i would be situated closer to them…

Good results! I would have thought cams would make more of a difference, but seems oem is quite good then. I guess the question is; a5 3.0tdi or 435d?

[@DarksideDevelopments]

We often see 10-20hp increase with cams, oem cams can handle it though. Depends what you're wanting out of a car really. Both can get big power numbers, but it's easier to do in a 30d/35d. 3.0 tdi is a mega platform though and sound better ;)

[@bartselter5332]

Torque graph looks very nice! Question tho, what is the backpressure at higher RPM?Also, it seems to fall off at the top end quite rapidly. Should have plenty fuel with; pump/injectors/cams. So i'm guessing the big hybrid turbo is the limiting factor at high RPM?

[@DarksideDevelopments]

It falls off rapidly because we're controlling exhaust heat, the backpressure at the exhaust manifold is 1.5 times higher than boost

[@bartselter5332]

@@DarksideDevelopments thanks for the response! 1.5x the boost is fine.👍 what EGT does it max out during a strong pull? Also, i’m running m57 i know its not comparable. But what rail pressure is the n57 able to maintain with this power and these upgrades? Just curious about the platform! Last question, do you offer remote mapping? My car is running “fine” with the current stage 3 map, but i’m seriously considering DSD for a remap. Engine has done 5k KM’s now, has all the upgrades required to push almost 500hp and 1000nm. I’m able to do proper logging using Testo, and i’m able to read and write the ecu. If yes, i will contact you private. 👍 Thanks for your time, i’m located in The Netherlands.

Is it really worth stressing these N57 engines?. I see M57 cars holding their money for what they are, E6x, E9x 535d, 635d and 535d all fetch a pretty penny due to the reputation the M57 has for durability once you take the swirl flaps out of the equation. However I hear the bottom end is a bit weak on the N57 engines, coupled with the timing chain failures, hence the reason fancy 6 series 640d's are selling for stupidly cheap money vs their E63 635d counterparts. If I had one of these N57 jobbies I would be leaving it standard and dropping the oil every 6k miles to try and prevent the disaster of spun main bearings and chain failures.

We've done a few high powered N57's now and not really had any issues with them. A couple of them have been driven for a good few years with over 1000Nm torque and are still holding strong so
