VF570 Maintenance/Replacement Parts Thread

[Bmwe46nyc]

Hello everyone, can somebody tell me if on the vf570 the water/air cooling system is connected to the car regular cooling system? Or is it independent? If it is do you have to change fluid on the manifold cartridge and/or the front water radiator? Thanks in advance…

It's independant.

Have you done a dyno run after the 2.62? How much did you pick up vs stock pulley?

Thanks..that's what I thought….had my kit for like 8+ years and I never checked/ changed fluid. So was wondering if that's something that's supposed to be done. I purchased car with the kit already installed and even though I've removed manifold , blower etc, I never removed radiator that came with the kit.

I've not yet hit the dyno unfortunately.

Got the car on the dyno over the weekend, I made the following on the stock MSS70:

561.2 flywheel bhp, 400+ lbft torque. I didn't bother to make any further adjustments as I wanted to spend the timing dialling in the MaxxECU.



And with my MaxxECU Race and some tweaking, I still have a little work to do on the mid range ignition timing to bring the mid range up to match that of the MSS70.



What was really interesting though was the air temps coming straight out of the supercharger (pre charge cooler) and it would start at ~35*C and end at 100*C on a 4th gear pull yet the post charge temps only climb a few degrees.



Just goes to show 2 things, the compressor is probably way out of it's efficiency range running a 2.62" pulley, and the charge cooler does a great job.

By the way, the car is on it's original head gasket and 143,000 miles!

The difficulty dissipating heat when SC'd has always been has always been one of the big knocks against FI for our cars. Would be interesting for you to get out on a track and really beat on it.

Hi! Do you guys still have this setup? If so, any issues with cooling etc?

[rscott]

Bookmarking this for later. Thank you guys

I think it’s safe to assume the cooling reservoir is not an off the shelf piece but does anyone know where I can get a replacement stopcock for it? o-ring is ok but the stopcock it self took some damage.

Having just purchased a used VF570 kit from an E46 M3 I had some fun sourcing some spare bits for my Z4M, obviously VF can provide the bits but they were very expensive, so I set about sourcing bits myself.

Mechanical Tensioner: 1128 1 427 252 or VKM 38202

Idler Pulley (INA): 532000110

Check Valve: Any check valve with an 0.275" or 6mm inlet/outlet will do.

IAT Sensor (Bosch): 0280130039

Belt: 6PK2040 (I'm running a 6PK2033 with the 2.62" SC pulley).

Air filter: K&N RU-3130

SC support bracket to oil filter housing bolt: M8x120mm 12.9 Cap head. Trim this down to ~110mm if need be.

Lower alternator bolt: 1x M10x1.5x160mm

Lower alternator spacer specs: 25.0mm O/D, 10.5mm I/D, 18.0mm Width.

Throttle body to charge cooler plenum boots: 6x BMW 11617835861 worked fine for me. Tuner Motorsport Silicone couplers also work fine: PN: 003313TMS03KT

SC Pulley:

• Stock size for the VF570 kits according to VFE is 2.87", Vortech part number: 2A036-287.
• A 2.7" pulley is available via VFE and the part number is CB257A
• A 2.62" pulley can be purchased via Vortech, part number 2A036-262. A 2.62" pulley puts you at just under 51K impeller speed at 8200 RPM so you probably don't want to go any smaller than this as the blower has a limit of 52K!

Vortech SC Oil: 009035

Spark Plugs: 6x NGK DCPR9EIX (Iridium) or 6x NGK DCPR9E (Copper)

Charge Cooler Radiator (NRF): 50547

FPR (BMW): 3.5 Bar - 13531729319 or Bosch 0280160597

Injectors (E46 M3): Bosch 0 280 158 117

Injectors (Z4M): Bosch 0 280 156 012

Water Pump: M-8501-L54

Charge Cooler lines: 19mm / 3/4" Heater Hose

Crank Case Vent lines: 16mm or 5/8" Oil / Fuel Hose

Top Radiator Hose (E46 M3): Remove the OEM clips from the stock radiator hose, remove the plastic ends and switch them to the opposite ends and re-clamp.

Top Radiator Hose (Z4M): Purchase 2x 38mm 45* silicone bends and a 38mm hose joiner. Trim the ends to suit and join with a hose coupler. VFE wanted ~$350 for their own hose.

Supercharger outlet to inlet manifold coupler: A 70mm x 75mm silicone straight is a better fit than the OE VF hose, trim it down slightly to suit.

Big thanks to Tom, aka Harber07 for his help with some of these bits.

I hope this helps!

Cheers

Does anyone know which spark plugs are the best?

[Bayern///M3]

Spark plugs: NGK 2641 - DCPR9E
Been running those on my VF570 set up for 15 years now.
i replace them every 20000kms because they are cheap.

From all the research I've done so far everyone's saying to go with the NGK DCPR9EIX (Iridium) Have you tried the Iridium version? And what oil are you running? I'm thinking High Performance Oil - Red Line 10W60
