It's been done before...on a RWD, one person has achieved it. Literally ONE PWG guy.

Wondering as I just flashed bm3 and they recommend the ngk two step colder plugs gapped to 0.02, I bought them but haven't installed yet and am looking for a reason to or not to install them lol
I was running N20 plugs gapped at 0.025 (see previous post)

Im not sure yet but I think something was wrong with the N20 plugs on my car.

OP#1: 400whp cannot be done on PWG
Me: Read link to 400whp car
OP #2: Yeah, but that's only one car

Good talk guys.

Either way 400whp on pwg doesnt mean shit tbh, its making the power down low. Up top EWG kills it. The stock turbo is just so shit, falls off so hard at 5k rpm.

Just reviewed the log of the so called 400whp dyno run. From what log says, dyno reads a bit high but numbers aren't far off. I won't give an analysis but I'll conclude it's pretty close, maybe 385~390whp better represents what that particular car is at.

But, this is a big BUT - that innocent man or his tuner is trying very hard to kill his tiny PWG turbo or the engine to say the least. With a ridiculous IAT increase from 80+ to 160+ in a single gear pull. He could upgrade to bigger IC to cool it down by 20-30F, at the cost of some 2psi(15-20whp) loss due to bigger IC flow restriction and still will be overheating. The problem remains regardless that turbo itself is generating heat at a much higher rate than anything can take. This isn't a kill map, it's a suicidal map.

In real world his car can't be pulling 2 or 3 gears without losing 1/3 power or even into limp mode. Pretty useless let me be straight.

Repeat, some people must be high. Less alcohol please.

Why do you keep referring to "tiny PWG turbo"? They're exactly the same size. EWG just can apply stronger closing force to the wastegate. A given boost pressure at redline is putting just as much pressure on stuff whether it's PWG or EWG.

No, they're different.

EWG compressor wheel is significantly bigger. EWG stock turbo makes even a little more than PWG Stage one turbo.

Plus a 4" turbine outlet vs 3.5" PWG, though some people question what difference that would make.

wrong info. in n20 case - yes, they are the same, in n55 case pwg compressor wheel is 62mm (exducer), ewg is 67mm (correct me if iím wrong). I also have pwg n55, but seeing dissapointing boost drop after 5000 rpm, I upgraded to stage1 pwg turbo which has the same spool as stock, but can give about 250-300mbar (3.5-4.5psi) more on top end with the same wgdc %. this cut my 100-200km/h time by ~2 seconds, if its a lot or not - decide on your own.

Yes upgrading the compressor wheel will give you more boost up top with same wgdc. Absolutely no doubt there. None of that has anything to do with EWG vs PWG though.

What is your source of the info that EWG has a bigger compressor wheel? I've been constantly trawling the web for years and that's the first I've heard ever.

Edit: I found the source (a Pure forum post). I wasn't saying you're wrong. Just that I was interested to know the source.

The EWG compressor wheel would definitely help some but the vast majority of the info out there indicates that the higher boost capability is mostly from the EWG being able to hold the wastegate harder.

just look at the photos of ewg/m2 (same size compressor wheel) and pwg turbo and you will see difference instantly

That makes me more sad about finding out my 2014 Euro 535i LCI is still PWG.

USA models changed at 7/2014. It looks like Euro 5 emission standard countries went even later with PWG

How did you figure this mate? I thought all cars post 07/2013 were EWG for sure?

I have a 11/2014 manufactured 435i. I always assumed that its EWG, and even flashed the EWG maps with no problems.

I checked on realoem.com which is a copy of the BMW parts catalogue.
It seems 3 and 4 series was EWG worldwide from 7/2013.

5 series USA was from 7/2014

5 series Euro models is 7/2013 for Euro 6 or LEV countries. I believe they kept using PWG for Euro 5 countries even longer.

Should get dragy for more accuracy. Its been already tested to be as accurate as being on a drag strip (someone compared timeslip and dragy time)

Geez I hope this is accurate ... 1/4mile @ 11.67 would be awesome!!!!! .....but it's a little far fetched... I'd totally believe high 11.9's maybe 11.8's ... can't wait to see some more times with that set-up...

Yea I'm sure it's not 100% accurate but even if 1/4 mile is around 12 I'm happy
