Take it from someone who tried literally EVERYTHING to get the most out of the PWG turbo. As you can see I gave up and just bought a PS2 and 400whp is so easy, I'm on shitty 91 octane. On 94, I can probably easily squeeze out another 50whp with a custom tune. There's no huge cliff drop after 5k rpm, and it just pulls.

My take on 3.5 and 4 inches turbine outlet difference.
Back pressure will be a bit different and thereâre a lot of advantages to take from less back pressure with turbocharged motor. As a matter of fact, BMW even uses 4.5 on B58 turbo. While catback pipe that is downstream of downpipe has always been 3 inches. It makes sense as exhaust cools down and shrink as it travels and needs a smaller diameter to keep velocity. Here is the thing: Far too many PS2 on the road are being pushed far beyond what it is designed for. But there is only so much PS2 can flow. In squeezing last bit power of it, meth, ethanol and a bunch of other dirty tricks play more important roles than half an inch outlet difference. Probably less back pressure out of 4 inches will net you 15-25whp depends on boost, but PS2 power varies from 400 to 550whp depends on setup, making that difference look insignificant.

Its actually true. IT was an early 4 series launch that PWG made its way into. Very few actually exist but they do. I believe theryre know as factory sale cars. Basically like dealer demo sort of thing. However I cant confirm locations, not positive if any made their way into the USA.

As hp for pwgs everyone' car is different with different dynos, weather, etc, assuming they have the same mods. But it goes yes from 340whp to 400whp. So you are fine saying "around" 400hp till you actually dyno.

This is exactly what i am talking about with these cars and tuning, everything is super subjective, there is conflicting information everywhere, and everyone thinks they are right lol

lots of wrong info here, like tuned 335i pwg is slower than stock 335i ewg etc, its BS. Don't waste your time reading everyone's opinion, here is +- correct guideline from Peter @ Pureturbos (power is crank hp of course) :

I'm speaking of my own experience, I did a pull with my friend with a EWG and I KNOW it's slower. |

stock 335i EWG does more than 360-380 crank hp? sir are you ok? or maybe you can show me _stock_ 435i or 335i ewg which does 0-160km/h (0-100mph) in less than 10 seconds?

When you go from a roll or once you get up to speed, you spend 99% of the time above 4500-5k rpm. PWG falls off a cliff after 5k rpm and ewg starts falling after 5800-6k rpm. That extra power band is huge for top end which pwg is lacking. |

you mentioned your theory several times. pwg falls off the cliff after 5500rpm, and it does 0-160km/h a little below 10 seconds (you can shift earlier to stay on powerband), so I'm asking once more, can you show _stock_ 435i or 335i which could do it also? all I see is 435i with mppk doing 0-160km/h (0-100mph) in about 10.8-11 seconds, I'm not talking about stock at all.

And even if you shift early to stay in powerband, you're losing 1000rpm which is huge, he's able to stay longer in a gear and make the same amount of power.

You?re absolutely correct there are a lot of comments in a lot of threads that are spread and are not true or here-say but there?s also a lot of experienced true facts and comments as well. Bottom line I think we?re all here to help and be helped.

tell about loosing rpms to heavily modified diesel owners like bmw 35d or bmw triturbo 50d with nearly 500hp, they will smoke any modified ewg 335i while revving max up to 4500rpm. If you think that horsepower at e.g. 8000rpm is more real than same horsepower at 4000rpm - you are wrong. horsepower is horsepower. You did not answer my question if any stock ewg 335i could do 0-100mph in less than 10 seconds? Every that I've tested was doing it 1.5-2 seconds later and as you probably understand - it's huge difference.

I see no pwg turbo options for 435i in any of bmw parts catalogues. That's it, if bmw made preproduction models with pwg turbos - would be interesting to enter its vin and see what turbo and ECU (pwg is mevd17.2.6 while ewg is mevd17.2.g) part catalogue would offer
