N54 Turbo Outlet Upgrade MUST HAVE for 500hp

- Hey today i am showing you guys how i installed my turbo outlets for my bmw 135i. I recently upgraded the turbos to viv 6x6 16t and needed to do the outlets too in order for me to push more than 500hp. It is an easy job however i struggled tightening down the v band clamps for some reason
These are the VRSF outlets you might have better results with other types of outlets however i would stay away from the silicone ones.
It is mentioned in the description, but I'd like to remind people that this is a >500HP mod. An aerospace engineer at a turbo manufacturing company clarified for me that turbo upgrades on the n54 in 450HP range benefit from keeping the stock aluminum outlet, and no bigger than 5.5" intercooler. Because the air is moving so fast at this stage, Bernoulli's principle makes the narrow pipe non-parasitic. Wider piping on the charge side results in greater lag because the turbo has to fill a greater volume with compressed air before it can reach the throttle. With huge twins and pipes, you can reach the 850HP target on this engine, but you'll be waiting for it.
A lot of people don’t understand this and will always just throw on the largest pipes and intercooler’s only to have a slower feeling car. Bigger is not always better. All parts need to work in conjunction with each other for optimal results.
I bought my car modified and it has a 7.5in stepped intercooler and I am considering swapping it out for the smaller csf intercooler.
If I just wanted all out top end power I would keep it but larger piping and intercoolers can drastically change how a car responds and spools.
I experienced this on my mk6 GTI when I upgraded my charger piping and intercooler. Instead of being quick and snappy, those mods made the stock turbo feel lazy because of the volume of space it needed to fill afterwards. I ended up swapping to a smaller intercooler and response was back and iat’s were essentially the same.
This was a great comment you brought up. It needs to be discussed more often as it seems not many understand this concept.
I think the main problem is people think that a big intercooler means better cooling, which it does to a degree, but larger intercoolers are really meant for cars running larger turbos and a lot of boost. They need a larger space to fill so the charge air is efficiently and effectively cooled down.
More air being produced by big ass turbos needs more space and surface area to be cooled down.
Realistically I think the 7.5in race intercooler is ideal for 700 and up. I think cars in the 650 and below range don’t need the 7.5in race intercooler like I have.
My turbos should be more responsive than they are but my intercooler is just too big.
So I have the 335is it makes more
Power then a 335i stock I know I should go catless dp but you saying not to go inlet and outlets? I want to make around 500
@N M I have the exact same thing going on with my 335is, I bought it with a bunch of modifications such as catless downpipes and a 7.5in stepped FMIC. I'm making numbers above 450hp on E50 but under 500hp. I was about to buy outlets until I came across this video and comment, I would take their advice and wait until that number crosses 500hp or you upgrade the turbos. One thing you could do is upgrade the inlets and make sure you have other things like a chargepipe, intakes, 1 step or 2 step colder plugs, and make sure all your maintenance is done/up to date.
@@noahzm_ I'd say first, upgrade the inlets. Let's just consider that your silicone inlets can't be much wider than 2" or they won't fit behind the rear of the engine. If you're going to crush that air down to 2.5 atmospheres, the internal cross section area of the outlets can be 1/2.5 that of the inlets (1.27" diameter) before choking the flow.
Hi, currently, I am mhd stage 1 with downpipes. I want a reliable, but decently fast car. As you’ve mentioned above, should I go for a 7in intercooler on ARM, or 5.5in ARM. I wanna be in the 400whp-450whp (reliable). And ARM inlets as well.
Old video but I agree with the more than 500hp comment and that's whp. So many mods on the n54 are based on hype. Been running an n54 for 10 years and so many times you will read from "experts" that a mod is a "must" with no dyno or science behind it. I can think of a few that are out there based on pretty sloppy evidence such as charge pipe meth, sports cats, outlets including the "crushed" rhd ones, dump valve spring strength, dual cone intakes. In this example I'm running 19ts with the stock rhd outlets, stock air box with Mr 5 mod. I'm sure if I crank it up to 600whp there will be some restrictions on the CMF the stock outlets can handle but for now at 550whp it's fine with wgdc lower than most I have seen. Turbos spool above 20psi at 3000rpm pretty close to stock as well. Yes you will help us the turbo a bit with a bigger pipe but as said at what cost for about 2% wgdc
I would recommend wrapping the silicone coupler between the two outlets in heat wrap tape. Im running pure600s on 19/20 psi and the coupler blew mid run 😓
Are u on 93 or e85
Exactly why I don’t wanna add these lol
hey I'm running the same turbos and I've had a shit ton of issues with the outlets and fitment, are you running vrsf inlets also? once I installed these outlets I'm having issues holding boost, I would hit target boost 24psi by 4k and drop down to 7psi by 5k. was wondering if u experienced anything like this?
Did you notice a nice gain with the inlets tho?
Noticed more with the inlets than outlets tbh
That forward clamp is a #$@%#$%$# !!!
YES!!! Agreed
@@menjicar I got it by wrapping some lock wire around the legs of the clamp, twisting until the ends came close enough to get the bolt started. Then use a ball end H5 socket about 3" long to tighten it. #$#@$#$!!
@@jackarsenault2216 that’s smart now I know 🙏 struggled for a few hours tbh 😂
I'm having such trouble with the rear one, fk
16t? Why not 17t? And how are those Viv holding up?
They are 17t and so far holding up for about 15k miles. Very little rattle sometimes
Where did you buy them 🤔
Ohh sorry they are from VRSF pretty popular brand
@@menjicar thank you and keep up the good work
