I have a 2004 BMW 535d, Sprint Booster installed, ECU remap and I would like to add a RPI Scoop to get more air in the engine. WIll that work for a Diesel? Or is it just a Petrol thing?

 

It will work - but how well I'll let you know as soon as I get mine.

I've also ordered a BMC filter but I wont get mine for 2-3 weeks.

 

hahahaa we're in the same boat. I am about to order the RPI Scoop as we speak (and as soon as Paypal allows me to forward the payment) and I also ordered a BMC filter as well, yesterday. I guess we will both find out at the same time. The Diesel being a Turbo engine and working with lots of air, would make me think it will like the added air pressure inside the air box.... time will tell.

 

Don't forget to report you two !

 

Happy days. It's ashame I'm
on holiday from thrusday next as that's when it gets interesting.

 

I forgot to mention, I also ordered the Angel iBright V3 white and some Matte Black grills. I will go all HID Xenon on Friday. I have Bi-Xenon as we speak, I will add Xenon on the Hi-Beam and on the Fog Lights as well. All 5000k temperature, clear white. It should look nice.
Regarding the RPI scoop, I have the air intake on the right side as I stay in the car, left side as you look at the car from the front. No RPI scoop was matching, so I got the M5 RPI scoops and will use the one that I need (adapt it if needed).

 

Q: Does the RPI Ram intake system work on the diesel models?
A: RPi has not tested it yet to know if:

1. the corresponding models will fit
2. if it will work and at the what capacity


More to come after some R&D.

 

Michelle, thanks for joining. As far as fitting goes, I ordered the M5 scoops. I saw all US cars (petrol ones) have the air intake on the left side of the hood. My European Diesel has it on the right side. A regular scoop wouldn't fit. I guess I will only use the left M5 scoop, it must fit. If it doesn't fit, I will see what can be done so it will eventually go in.
As for point 2, I don't know either, I never seen one installed on a diesel. It should work, considering a turbo diesel consumes more air than a naturally aspirated petrol engine. All extra air should be welcome.
My scoops are on the way, I should have them in a week.

 

Just wondering the same thing - people in Europe also need some powergains

 

We have powergains in Europe, we just need more. What we really need are some improvements for Diesel engines. There are only a couple of options for Diesel engines, we want more. Speaking of diesel options, there's a new ECU remap from Hamann for my 535d, 350hp and 660Nm. Should I go for it? I am currently at 315hp and it pulls like a rocket.
