BMW F30 320i Stage 1 and 2 on dyno!

Subtitles on. N20 BMW 320i Going from Stock dealer Performance Flash to Stage 1 and Stage 2 power. Brilliant car as a cheap quick daily.

[@teamgimps]

Perfect explanation of all things! Very good company presentation! I'd get my car done there, if I didn't live in Scotland!

[@EuroSurgeonNz]

Im sure there will be a tuner near you. Just ask simple questions. 1. Do they have dyno? 2.Ask them if they log timing retards and fuel trims. 3. Can they do adjustments based on that.

@@EuroSurgeonNz Thank you for the reply. Seems like the 320i might be a good way to go.

@@EuroSurgeonNzno the 328i will get to 300-310 on stage 1 while the 320i gets to 240-250 on stage 1 so the 320i gets to stock hp level of a 328i on stage 1

[@kokoricky3067]

would a b48 provide better numbers? Are they more reliable? reffering to a 2016 320i lci. And what mods are needed for a stage 2? Downpipe and intake setup? Would i be expecting 200rwkw from a stage 2? Thanks awesome video

Since when did the F30 320i ever come with a B48? The engine cover is a clear indicator, but some parts will quite literally have engravings saying “N20” on them.

[@warsawjadore2740]

Thanks, I bought F31 320iX and starting to push it much harder, maybe to 305HP. So should change pistons, intercooler, intake, map, downpipe. It has 150kkm and was driven by old lady before. Any other changes? pls an advice

[@EuroSurgeonNz]

Personally just wouldn't recommend pushing the n20 past 300hp. Catless, Cooler, Intake - Should be fun enough. Anything past that - Start with somehting that is made for 400+HP

Great video! I have a 2018 320i all I would need to gain hp is a down pipe? Will I need a tune also ?

[@EuroSurgeonNz]

you will have a different engine, b48 instead of n20, and start with the tune before you do the downpipe:) in saying that, b48 tends to melt cats a lot so tune + downpipe is ideal.

[@mmmskyline]

hi, your workshop is literally next to my house, i'm in greenlane haha. just been looking at the 330e, they are supposed to have the same engine as these 320i? the B48 right? so would I get good gains from similar mods as you've done to this 320i, other than having more instant torque from the electric engine?

[@Everloveless]

Following as well! I'm getting my F30 330e this week! I'm also curious whether the tuning can be done the same way as the 320i does.

[@mmmskyline]

oh nice, your in NZ? i been looking at 335i active hybrid at the same time as well, looks promising

[@Everloveless]

Nah I'm from Malaysia, our specs from 2017 and above doesn't have 330i anymore, the top spec has been replaced by the 330e so I'm getting that one.

[@EuroSurgeonNz]

Hey Tovey. 330E with B48 is a slightly beefier version of b48. The end result is solid mid 300hp at the engine with close to zero turbo lag. The closer comparison betweent he two would be older N55 335i and AH3. But yes, with similar mods as in this video 330E gets around 80hp extra and 120-140nm of torque bump. Would love to do the video on one.

[@akent46]

Q: What did BMW do to the 320i engine after 4500 rpm?? In stock form the power just stops, such potential out of these things.... tune and 328i beater!

[@EuroSurgeonNz]

To separate it from 328i, they literally brought down the power request. From throttle closure, to lower boost, fueling, torque limitation etc. Merc were the first ones to do it on C63 W204. Got a separate video on that.

[@senadselimovic8649]

Hey I have a f30 2018 b48 2.0 engine and there is a lot of tuners that can optimize my car up to 300hp. But where is the sweet spot on where it cant destroy my engine? 250hp? And did you hear about BSR brand?

[@EuroSurgeonNz]

If i remember correctly it depends if you have GPF or not, but the non GPF cars are reasonably happy at 300 ish. Sorry pass on BSR, looks like another "bluechip" hand held flasher gimmick thing. Would suggest taking it to someone with set of rollers, as this is literally the only way to datalog the car properly and to see what the output is.

[@EuroSurgeonNz]

Unless you want to do multiple 4th gear pulls with traction off from 1500rmp to redline :)

[@EuroSurgeonNz]

There is no rule of thumb on what power/car has issues. Everything can be pushed to the limit safely, if you have matching hardware. Just find a reputable tuner in your area that has dyno and can provide full logging of the car

[@LuisMartinez-tp5oj]

@@EuroSurgeonNz GPF would make more exhaust counterpressure as so does the catalyzer, I have one 120i b48 and I imagine it has those parts so I would expect 260-270 hp from a safe calibration😛

[@luffararnesugerkuk]

Yeah BSR claim 278hp on the B48B20A, wonder why most other tuners come even remotely close to those numbers, they claim 310hp or something on the B48B20B which may be more likely but probably not haha. 11:1 vs 10.2 compression ration unless I am totally off, to me that is a big deal and no personally not all B48 are the same. I went for the 330i just cause of that, but 100% new to BMW so take anything that comes out of my mouth with a full lorry of salt. Check with the experts instead.

[@sanzvlogs5157]

I have a question with regards to pops and bangs ? are they harmful for these motors ? does the n20 motors have any weak piston ring issues ???

[@EuroSurgeonNz]

Generally speaking all pops and bangs are harmful. You are throwing unburned fuel at hot exhaust. Then detonate it right next to turbo/Wastegate/o2 sensors. Generally avoid like plague unless customer signed a waiver.

[@costelariton9864]

hello, quick question, my N20 320i is reaching 173 hp crack power, i tuned at 1,4 bar and i reached max 224hp crank, what is wrong with the engine? torgue i had 370 nm, tha same like a 260 HP power . any advice will be appreciated

[@EuroSurgeonNz]

Morning. Without datalogging is like asking a crystal ball. But lets try. Subject to to your ignition system being alive (aka coils/plugs), HP reading is top RPM, meaning you are not flowing enough up top. So Blocked cat/ Throttle closure/ turbo not very alive. Again, all guesswork without having car on rollers with logger.
