Default BMS N55 E Performance Intake - Worth Getting One? - 07-02-2017, 10:49 AM

Am wondering whether to put a BMS Performance Intake on the car (or something similar if anyone's got any suggestions?) but am not sure if they'll be a benefit?

Have read a few reviews/posts and the general opinion seems to be that the E N55 OEM unit flows quite well so, would there be a difference? The majority of these comments are however from people with minimal mods so it would be good to hear from anyone who's got one of these and is running high boost.

Thanks

Adds a bit of hp, looks fantastic, sounds fantastic. Helps with turbo response as well.

Thanks Payam,

I'm about to order a few things from BMS so, unless anyone chimes in with something to the contrary, I'll include one of these .

Caused slower response for me, went back to K&N drop in filter.

Thanks for posting - haven't seen that before

Have you tested/tried anything further since your post on 11th May?

Ran it a bit more and just felt slower. Switched back to my K&N and haven't felt like trying it again. Thinking about a custom intake all the way to the Pure inlet.

The bms intakes just sounds nice, I didnt really notice any gains. Now the the injen sp intake I actually noticed my car was faster and responded better.

First time Ive ever heard of that. Most of our customers notice an immediate difference

I think the injen is a better made intake. It replaces both factory pieces and connects directly to the turbo inlet with a true 3" diameter. I ran the Bms one before I got the injen, it worked well I just didn't like the way it's designed to mount up, and still uses the factory tube/coupler. it also rattled on the cowl in my 1 series.

My car wouldn't even run properly with the bms Intake when I would go WOT. Not common but it happens on some cars. I had No issues with injen intake though for what it's worth.

So I take it you're both running the Injen Intake?

Also, have you noticed/logged any tangible gains? At the very least, it hasn't negatively impacted performance in any way right? Hearing arguments for intakes on our platform is almost 50/50 in terms of whether or not "it's worth it".

I use direct port meth(none of it is pre sensor) my IATs are a true reading. I've been using the VRSF 7.5" race fmic with it and only saw an average of 6* rise from a 2-3-4-5-6 pull on 18-19psi. I doubt you would see a temp difference between the plastic and metal tubes when WOT.

Intake is an intake, the injen is louder then the Bms.

Here's a video of my car when it had the BMS intake.

Don't have one of the Injen.

I still wish we could have a maf delete, or some sorf of a maf extentsion cable so we could simply slap a filter directly onto a pure inlet!

I am not. Wish I didn't sell mine because I would run it now. Initially I removed it because you get a little more dust under the hood with the open intake, so I removed it for a while then ended up selling mine. As newguy mentioned, the piping is 3 inches I believe all the way to the turbo inlet, which is good imo because it replaces all of the stock intake components up to the inlet. Probably the best option next to a filter directly on the inlet, which isn't possible right now.

come to think of it, if the injen intake pipe is 3" all the way and around the MAF aswel and it doesnt mess with the maf readings of the car, wouldnt it be possible to make some sort of a maf connector extention and stick the maf right on a 3" smaller intake right near the inlet? it would still be a 3" intake with a maf connection, just a really really short one.

Well, thanks for all the responses. Was thinking it was going to be a simple case of bolting on the BMS kit. How wrong was I

Time for a re-think

We pressure drop tested all of them. The BMS intake performed the best (tends to happen with shorter piping) and unlike the Injen didn't rub on our hood or heat-soak sitting in traffic. That said hp gains between them were all similar. So pick your poison!

If you notice a performance difference it's not from the intake differences though.

This would be great, but I think something with the maf needs to be rescaled. Which I believe can be done in mhd, but not sure.

What caused the injen to heat soak vs the bms not heat soaking? Is it the metal pipe vs plastic? Would love to see the data.

Also, When you pressure tested intakes, did you do it from the end of the main intake pipe or from the piping that connects to the inlet? Asking because all testing I have seen us from just the end of the main intake pipe, not from the inlet, which is the portion injen replaces.
