Hey everyone.
I have a 2013 F30 320i PWG and am planning a tuning/ modding project with the goal of reaching 300 hp.
I have browsed the forums extensively but can’t find a clear answer for my exact situation.
My goals are as follows:
1. Reach 300 hp
2. Achieve optimum burbles
3. Do this all within the best safety margins

I am planning to install an Armytrix Exhaust and down pipe as well.
I live in Egypt btw.

My options are:
1. Bootmod3
Pros:
Customizable Burbles
Safe
Smooth power delivery

Cons:
Bootmod3 only advertises a 20% (stage 1) to 30% (stage 2) increase in hp for a PWG car like mine.

My local tuner claims I could reach 250 hp with stage 1 and 280 (stage 2) with a FMIC and finally 300 hp with an e30 map.

2. JB4 + methanol injector

Pros:
More aggressive tuning could help me reach 300 hp

Cons:
No burble customization
Delayed power delivery

My local tuner claims I could reach 250 hp with stage 1 then 310 hp if I add a methanol injector.

3. Magic Motorsport

Don’t really know much about this tune and haven’t found anything online about it.
Local tuner and magic motorsport website claims 274 hp (Stage 1) with stock car.

I am leaning towards Bootmod3 as I love the burble customization but I am afraid I won’t be able to reach 300 hp even after adding a FMIC.

If JB4 is the only way to reach 300 hp and can produce a good sound I might go with that, but I am apprehensive because of having to deal with a methanol injector and delayed power delivery.

What do you guys think I should do.

I have a full FBO+, catless downpipe, FMIC. and Bm3 Stage 2 agg. I just recently dyno it and it made 254whp and 302tq. I wanna try to run 300whp, but I don't know what else to do.[IMG]undefined[/IMG]

Do you also have a 320i PWG?

That seems low for Stage 2. Stage 2 328i should be 290ish, 320i should be 260-270 minimum. Stage 2 320i gets like what, 220-240 or so? A tune and DP should make that jump a lot. Maybe try a regular Stage 2 map and redyno? Seems a bit low.

The issue is can we see those same gains with a PWG 320i on bootmod3?

He is making 254hp and 302tq at the wheels. That translates to about the crank horsepower you listed.


Like the OP, I am also struggling to find a route to the power target I had in mind (315-325hp at the wheels).

Oof that's my bad, didn't even see lol. Regardless 300 is a stretch unless you go forged pistons and an upgraded turbo. At that point you just grab a 335/340 and call it a day lol

[sqwinny]

At the wheels? It's going to be a full bolt on affair. Every little thing makes an impact.

Exhaust side is going to be cat less downpipe and exhaust with as little restriction as possible (this means resonators too as they negate maybe 1-2 who tops).

Intake side is going to be:

Intercooler to keep temps down. (Depending on your climate could be the 5" Amazon special or you light need a 6.5 VRSF/ER/ATM/Wagner comp 2)

Turbo to intercooler pipe
Intercooler to intake pipe
Turbo inlet pipe

Tune.

Bm3 stage 2 e30 should get you there. Best bet Is a custom stage 2 tune.

JB4 can get you there with e85 as well but you're playing with fire as JB4 is more aggressive than bm3 without a custom tune.

Last but not least will be transmission dependent. The 8at puts down less than the 6MT. Does the transmission flash change this ? I'm not sure.

Do you have issues with your wheel bearings? Any friction between engine and dyno will play a factor.

JB4 posted this dyno before. Full e85 stock nets 300whp/351wtq

Yeah, I'm beginning to lean towards the 335/340 option.

Me as well ahah, I'm gonna wait a year or two and hope that a 235/240i is in my price range. Without a doubt the 335/340i will be insanely affordable soon.

[Sad N26]

This time, I'm going manual.

Thank you for your informative response.
Will the fact that my 320i is a PWG affect my ability to reach 300 hp especially with bootmod3?
I was really disheartened when I saw that their expected max gains for PWG 320is are as follows:

Stage 2 E30 octane: up to 33%HP / up to 45%TQ
Which translates to around 240 hp only.

Maybe a custom map could remedy this after full bolt ons.

The JB4 dyno with the e85 map is for a 328i and not a 320i.
The 320i dyno burger tuning posted also doesn’t specify if it’s a PWG or an EWG.

Sadly where I live a 335i/ 340i is too expensive because of government taxes and tariffs.
I am stuck with my 320i for now.

If you want to get close, you need to go BM3 custom (not OTS) flash tune, and then use a JB4 as your WMI controller and run meth.

JB4 Settings:
-Latest Firmware
-Map 0
-Meth Trigger = 4
-WMI Min Flow = 10psi
-Scaling = 60

You can only take it to 20-21psi before you crack a rod on the N20, motor isn't very strong. You could build the bottom end, but then you need a new turbo as well. Dollars don't come back in your favor.

Best to just add Meth and do as much tuning as you can.

I don't know how the N20 pump can flow full E85, not that you really want to run full E85 anyways. E60 is where the real money is, but I have no idea how the stock HPFP can flow that, I'd think OEM HPFP has about E40-E45 tops in it.

OP - Do you have access to Ethanol or no?

I'm not sure on n20 vs n26, but its been discussed that the n26 will make the same power as the n20 with 1/2 less pounds of boost. Not sure of internals strength. Mind you I have no experience, but can only go off what I read.

Pwg/ewg I'm not sure of the differences other than actuator. Can't tell you power limits either. Most people convert to ewg though.

Thanks for your response. Meth seems to be like the best option right now.
I am thinking of running bootmod3 as you said to take advantage of burble customization and smoother power delivery with JB4 for meth control.

I have very limited access to Ethanol and it is expensive over here.
However, methanol is more available and cheaper.

Sorry for my ignorance but can my car be converted from pwg to ewg.
How would I go about doing that?
What is the expected cost?

[sqwinny]

Anything can be done with money. You'd have to eliminate the vacuum lines and swap over to EWG. Some coding in the DME and it works. I don't know the entire process nor all it's details so take my advice with a grain of salt.

Start with BM3 and JB4 for meth. The turbo you have isn't changing...

[floridaorange]

It might be fun to imagine your 320i with 300hp, but in practice, you'd be driving a ticking time bomb at those levels.
