Yeah I have no idea how this could be done easily without a lift. I have a mechanic local to me that I only trust to work on my car. I watched him do most of the install, and realized I made the right choice letting him deal with it.

I like the look of the turbo smart, was going to go DV+ originally but this is the more complete solution it appears.

I'm going to get it installed for me though as can barely do half beer car jobs!

Got mine installed today, along with the Pure Turbo Inlet and Wagner Evo3 Comp.

Throttle response/lag is definitely better, but no idea which of those parts is helping the most.

Evo3 will be making throttle response worse so it be DV and inlet upgrades combined 😉

IDK, Wagner shows the Evo3 has less pressure drop, and a Wagner rep confirmed it to me: https://www.wagner-tuning.com/produc...0001144-4.html

I think it's b/c they enlarge the IC inlet/outlets and provide their own larger pipes to go with it.

Interesting.

Larger bore is for cold outlet only ?

Hot inlet side uses same sized coupler as stock ?

Honestly can’t tell you for sure, but if you want to reduce pressure drop increasing the outlet of anything always has more impact than increasing the inlet.

Looking at the pictures on Wagner link you sent - silicone bottom half of CP has reduction in ID to suit what looks standard ID of top half of CP to TB connection....

Not sure I follow all that, but from the description:

“The stock click connections have been eleminated and increased to a connection diameter of Ø65mm/2,56Inch for inlet and Ø76mm/3Inch for outlet, so this kit comes with reinforced silicone hoses as well as 3 aluminum chargepipe.”

What do you think?

What do you think?

Throttle body end is 3" connection.

Looks like CP silicon and hard pipe sections are less than 3"dia

3" outlet from IC surely would only bring a benefit over competition if the evo 3 CP was constant 3" ID too ??

Does Evo 3 install involve mods oem bracing ala Dinan cooler ?

No idear. You guys know the details like this better than I do.

All I know so far is throttle response is better, but could be more from the TS BOV and Pure inlet pipe, and IATs are better than Evo2--more data coming on that.

What's the stock IC outlet size and diameters of the typical aftermarket charge pipes?

You do have to change to the M235i radiator v-brace, and we cut the ends off the bottom sides of my M2 brace to get additional bracing to the bottom two bolt locations on each side.

GerardzM and I have an Evo3 specific thread going here: https://f87.bimmerpost.com/forums/sh....php?t=1727351

Hi All,

If you can, please can you post a log with your VR11 installed? - it would be great to see what differences it is making to boost during gear shifts.

Ideally a log with shifts less than 5.5K RPM, as well as those higher in the rev range.

Thanks in advance,
WT

I have some logs posted in the Evo3 and HPFP threads. Good luck figuring anything worthwhile out.

I finally heard the fluttering sounds some guys have mentioned. Very faint and only heard when going slow around town with the radio off. Not annoying at all, just a new, different sound.

Thanks for the info re the logs.

Although they didn't have the sub 5.5K gear shifts, they did provide what I was looking for to compare how the DV holds boost.

From my logs (stg 2, but with OEM DV), I see PSI drops as follows:

1 second after throttle let off: 5.9psi
2 seconds after throttle let off: 2.7psi
3 seconds after throttle let off: 2.5psi
after this, the PSI slowly drops to virtually nothing (0.2PSI)

From your logs with the TS DV:

1 second after throttle let off: 6psi
2 seconds after throttle let off: 3.5psi
3 seconds after throttle let off: 3.2psi
after this, the PSI goes down super slowly, levelling at ~2.2PSI

So for me, the benefit that the TS DV will give to responsiveness following gearshifts looks to be small. However, there is some benefit to responsiveness on-off the throttle.

Bee Pee I know that you are running the GFB DV+, please can you share a log of that for comparison? It'd be interesting to see what that large spring in the kit is doing in terms of holding PSI.

Cheers,
WT

Keep in mind that I’m DCT.

Good shout - thanks for clarifying.

It would be good to see logs for a manual for sure, but the DV should be operating in the same way. The above is consistently seen across your logs where you let off the throttle, and is very similar to mine, except for the differences noted that must be due to the DV. Could be wrong, but I believe for that second or two after accelerator lift, the engines in both DCT and manuals should be working way in terms of boost management.

Any logs?
