- BMW M2 N55 Dorch Stage 2 HPFP Full E85: First Drive
This is the first drive in the M2 with the newly equiped Dorch stage 2 HPFP. The was not able to maintain HPFP on a e30 mix, however things are now certainly very different.
Other than changing the spark plugs video here: • BMW M2 Spark Plug Upgr... , the only thing needed to get this cars HPFP problems solved was the Dorch pump. Install video here: • BMW M2 N55 Dorch Stage...

Looks like that thing gets up and goes real good 😊 keep up the good work guys 😁🤘🤟
Thanks man! This car is awesome. The owner does thing properly, no expense spared type of guy. I think his exhaust cost more than my entire 335 🤣. But it sounds amazing, goes really well and still very refined when you just want a nice car to drive. This video definitely hides the speed, she gets up and goes. Looking forward to seeing what it’s like on the final tune.
Dct gearbox definitely makes a big difference. Great to see the fuel pressure issue is sorted. 👍
3 grand is is a lot money though, 😣
It’s mega. But it’s fixed a problem, well it’s basically doubled the fuel pressure and support from dorch has been rather impressive. You get what you pay for.
You guys deserve way more subscribers
100 times more.
The quality of videos and everything is just top.
Makes me regret buying E61 N54 because none of the mods fit...
Thanks Slow 335i. We’ll keep cranking the vids out and hopefully more people will keep finding us. It gives us a chance to keep learning how to make better videos before too many people see us 😂
Dominykas e61 would be pretty cool pumping out some decent power. What mods have you had issues in regards to not fitting the e61?
Zero To 60 it’s xdrive so none of the downpipes fit and the one that is made for xdrive, is very small because of clearance issues so really there is no point of modifying the damn thing.
Ohhhh snap! Yeah xdrive makes things difficult on the 5 series platform. It’s a bit junk yard but what about getting someone’s stock downpipes that have the cats blown out? When I switch mine my front downpipes cat was pretty much hallow. Would be so cool to see a 5 series wags running decent power.
I love my stage 2 Dorch on my 2016 340i with the B58- it changes the car 100% E mixes are out of this world
Ohhh b58 on e blends would be insane. I want a b58 sooooo badly! Haha here’s a question, what do you think is the better engine b58 or the older s55? Better in terms of tunability/reliability.
B58
I think I might be with you...... In stock form the s55 all day long, but if you want to wind the power up, I think the b58 and especially the b58tu is a much better bang for buck.
finally got myself into a 335is! following your lead
Yes!!!!!! I’m jelly of your gearbox. What’s the specs on the car so far?
@@ZeroTo60Tube its stage 1+ right now with dual cones and FMIC chargepipe with BOV, but previous owner did all kinds of suspension goodies at a super high quality
Love this. I know I’m late to the party but does this have the stock exhaust and downpipe on? Cheers
No its running high flow cat with an IPe cat back system.
Will you guys be putting it on a dyno?
Will be purchasing an M2 early next year and will be modding immediately.
Would like to end up with around 330-350 rwkws or what ever the turbo maxes out at
The owner probably will eventually at some point for sure. 330rwkw in one of these would be a pretty damn cool street car. Once the tune is all finished we'll run the logs through virtual dyno and get a rough idea on power.
I'm reading with interest stage one turbo conversions. To not put more crazy power through the M2 N55 but give a better top end. I bet would play well with the HPFP? You guys looked at stage 1 turbo at all?
It has been looked at. Although these don't feel as strangled up the top end as the N54 stock turbos. It would definitely be a big help. Haven't found an option that was over appealing price-wise as yet. Have you found any you like yet?
It's something I may do way in the future as I'm keeping the car for a loooong time. Pure stage one turbo isn't too expensive if I e understood right I'd need an EWG version. I think it's about a grand here. It's more an OEM+ turbo than big tune and big power. Not interested in 500hp to the wheels car is pretty well balanced from stock but would take another 30-40hp I suppose.
I have the same setup on my n55 m2, but there are some metalic noises from the motor . Wastegate valve? Have you ever heard anything like this?
Not metallic noises. Have you put a stethoscope on it to try and pinpoint it?
You are welcome to Sweden, to test my m135, xdrive, TTE550+Dorch stage2 hpfp and Walbro525 Lpfp, soon ready, need to map it...
How have you found everything so far? Any fitment issues or surprises?
Zero To 60 have not got my car yet, still att the carmechanic
For reference, my car with some lightweight mods and the MHD N54 V5 E40 does 7.1 for 100-200 :D
Thats moving! Not many OTS cars get low 7s. What are the lightweight mods?
How bad was running E30 on the stock HPFP? I'm considering trying it. Currently on Stage 2 FBO through Bootmod3 and no issues with fueling. When the HPFP "crashes" or sputters, can it damage anything? From my understanding, some cars' stock HPFPs handle E30 map quite well, others do not. I have a friend who's fuel pump crashed on a stage 1 tune. Thanks in advance and would appreciate some feedback on running E30 map with the stock HPFP.
This was also no a go on the stock pump at e30. Seems to handle full e85 perfectly with the dorch.
@@ZeroTo60Tube You’d still need to upgrade the lpfp to maximize the potential of full e85. Right?
I’m fbo, 6spd on e30 and i pull harder than this. I see it targeting 20.8psi
@@mariomunoz7167 On a stock turbo, there was neever an issue with full e85. However a stock turbo wont make much power. What is your dragy 60-130mph or 100-200kmh? Thats the only way we will know how much slower your car is!
Looking forward to those 100-200 times! Hopefully below the 8sec mark? :)
We shall see
Would you rather have the lsd or the dct from this car in the n54? Pick one only.
The lsd. Definitely at my power levels anyway. The zf6 when tuned is a great box, just not as fun as a dct. The open diff on the 335 is a fun killer.
M2 looks to be quite a car, so glad i have a DCT it really is a good box, especially in sport manual
Your car should be pretty similar to this as an experience, once it gets wound up a bit! Apart from the LSD ofcourse. I will shoot you a message about sunday later on btw.
LSD, should be the first mod to a non M. :D
Hi, does the M2 have port injection? Or is the stage 2 dorch handling full e85 without port injection?
No it's just DI. Dorch stage 2 will handle full e85 on stock turbo no worries. However if it was my car, it would be going PI and better turbski.
@@ZeroTo60Tube I’m fitting a pure stage 2 with Dorch HPFP and precision race works LPFP. But without the Dorch lift kit which is coming soon, I can only run a blend.
@@ZeroTo60Tube Why port injection? The dorch stage 2 can handle 650rwhp, 950 with the cam in the lift kit upgraded? Numbers I’d doubt you’d see anyway.
@@adamwright8310 Why only a blend?
You upgraded both hpfp and lpfp. All you need is a custom flex fuel map from your choice of tuner to run it.
@@mariomunoz7167 I havent seen a strong DI only car. 650whp is kissing 800hp at the crank. That would require 130hp fuel flow out of each injector and i have never seen a BMW DI injector flow 130hp. Not for more than a single pass. Realistically 100hp per DI injector is already pushing its limits if you want it to do it more than a few times. Port injection is the ONLY way to make a BMW engine fast. Or any engine on any platform.
Hey guys,
Do you have any dyno numbers for the M2?
No, but i have done enough draggys, to know it will be 525whp on a dyno jet and around 460whp on a dyno dynamic roller. The car is doing low 8 second 100-200.
@@ZeroTo60Tube I just put the Dorch lift kit in with stage 2 hpfp, ps2 turbo and dyno on dynamic dyno made 509 whp on e85. I wanted more but it’s fun
Stock Lpfp? Stock turbo?
Yes, for now, still haven't fully wound out the e85 tune yet. Hopefully lpfp keeps up.
Hi, already have 100-200 time?
Done a few runs in this car, once the tune is finished, which its not yet, we will talk about times.
I've recently started using a ~26% ethanol mix of 16L E85 to 36L of 93OCT/98RON. This Makes a 99 Octane fuel mix, running the MHD 98 OCT Stage 2+ map on my M135i N55 EWG.
I'm running upgraded NGK plugs gapped to 0.22", Wargner tuning EVO 2 intercooler and 5W-40 oil (its hot in Queensland).
Logs are looking great, almost perfect, even without the downpipe upgrade or upgrade to fueling. My HPFP I've only ever seen dip to 2300psi during gear changes and during single WOT gear pulls its always within +/- 50psi of what the map is calling for. It's holding 16psi @ 10.4 deg timing in 5th @ 6500rpm with IATs around 38C max ~27C ambient.
I must have got lucky with my fuel pumps, car is so strong, Ethanol also fixed a lot of my post shift timing corrections too. Pulls hard as from mid range 7000rpm. Certainly feels like the 650Nm+ claims are true.
I have n55 535i with stage 2 Dorch hpfp and walboro 535 lpfp I have fbo and full exhaust can I run full e85?
Yes, with the right tune, on stock turbo your fuel system will be fine for full e85
stock LPFP?
yes
100-200?
We will check that once it's fully mapped. We have the data from when it was on BM3 ots stage 2 95, so it will be interesting to see the improvement.
Thumbs up for DSC off :D
"It feels very linear, it comes on like a surge" I swear people don't understand what linear means.
Comes on with surge of power at 2500rpms and is linear to 6500rpm…… make sense yet?
