@BQTuning @NoQuarter @WedgePerformance ... I am dubious this would fit under the Z4 hood line ... ?

I wish he would have copied my charge piping, I think mine looks a little cleaner. But overall glad to see more people doing it
Just buy a stock charge cooler and a can of play-do!
I finally received an intercooler from eBay that is not leaking, though the people didn’t package it well and bent one of the ports... I guess it’s fine for now. I also ordered a CSF clone for evaluation.
Doubtful. My port meth nozzle set up too high for my strut brace and I had to turn them around because one of the support braces hit and I couldn't close the hood. So again... Doubtful.
I have a feeling the hot side charge piping being different may be due to having to clear the e36 body moreso than anything, but that's just pure speculation on my part. I know he tried a couple different sizes between mock-up, dropping it in, and finally now with putting BOVs on.
Personally I kinda like the idea of having the BOVs where he has them just because of the old "one valve per turbo" thing (and I also run two universal Forge VTA valves) but I'm curious to how the response would be being pre-IC only rather than at the TB like most of us run now. I know from my experience of running two 25mm inlet dump valves that the response is just as good as any larger TiAL/TS style valve but they're still in the same location, I'm curious how much the throttle response would change if we didn't have any valve by the TB.
We do have the 740i intake that fits which is pretty high.
I need a new strut brace solution that goes around it. Maybe something that was made to go around this would be close to modify for the Z.
Looks like Burger Motorsports has started importing charge coolers and undercut the market quite a bit! You still need the brackets though.

Phoenix Racing High Capacity Replacement S55 M3/M4 F8X //M Intercooler
Deliver consistent, reliable power run after run. The small S55 factory intercooler is weak and prone to heat soak which decreases performance. That's why we made this liquid-to-air intercooler upgrade which will lower your intake air temperatures over stock and improve engine performance.

Now that is quite an awesome development. I'm sure it can lay there without brackets too though
Just a brief update, my car is running on a stock cooler with an E85 tune, datalogs from some pulls with ambients around 75f are below.
Once the E85 tune is acceptable, I will drop to about E50 and run the FF module, so HPFP should not give me any issues.
I had previously had some issues with IATs getting too high, but it does not currently seem to be an issue, I think it was from the leaking core draining out the coolant.
I received my alibaba charge coolers, they both arrived damaged. Quality looked tolerable, but the shipping/workmanship issues and a good deal led me to order a VRSF charge cooler.
Still no development on upgrading the heat exchanger, which was my original first priority, but the leaking charge cooler and excessive work hours got me way sidetracked.

Hello, I'm doing a custom under-mount big turbo (BW 8474) on my European RHD M235I, one of the issues I've faced is having to move the turbo forward to clear the steering shaft assembly, this then caused the thermostat (which mounts directly to the radiator) to interfere with the big 4" suction and 3" turbo discharge pipes. I have been considering going A2W to eliminate the 3" discharge pipe from the equation, which should allow the thermostat to remain in the stock location but I'm hesitant to do this without numbers..... any Updates? id like to see the final out come and performance numbers!
What are you looking for specifically? The setup was totally different from yours, but basically the end result was ~405 whp on pump gas for old stock turbos and auto transmission. A newer manual n54 did 430whp on the same Dyno with bolt one and MHD off the shelf tune. Nothing super impressive.
I am currently revising the setup for a set of RB 2 plus turbos, but still only shooting for 500whp on pump gas.
It sounds like the w2a is a good option for you, what is your desired function with the car?

Finally got my hands on some M4 aim track data, and thought I would share it here. Its from Zhejiang Circuit on a hot humid day in China. I do not have the exact air temperature, but think 30C / 90F-ish. That kind of weather. The car had a stage two tune but otherwise stock.
IAT heat map and channel report (最大 means max, so up to 87C 206F intake air temp):
Oil temp heat map for comparison:
To me it seems the oil cooling is doing better than the IAT cooling.

I am aiming for a reliable, powerful and uber fun daily driver ! I want to make upwards of 600whp (but I'll take more if I get it!
) on 95 RON pump with water injection. Because your twins are smaller they will produce more heat, at 400whp you should be making about 460 at the crank which would equate to about 45 to 50lbs/hr. air flow from your turbos. I am interested to see what your IAT's are like and what your daily driving (heat soak) temperatures are like. The BW is rated at 950hp, producing 95lbs/hr. which is roughly twice that of yours , logic would suggest that it would produce twice the heat but as we know larger turbos run cooler so this assumption would not be correct. I have already formulated and started actioning a way around the issue by relocating the thermostat and extending couple hoses, this will work like oem but I like the A2W intercooler as an option if it functions properly!
87C is HOTT! but the question is, is this due to turbo efficiency or poor intercooling?

that certainly seems achievable given what the S55 crowd is doing, I think that the CSF has been used in applications up to 900whp. The stock intercoolers are a beautiful lightweight design, but they are unreliable in my opinion, I would take the weight penalty and go aftermarket if you can stand it.
Anyone have any experience using One of these?

Ok, so I bit the bullet and went with the Phoenix Racing unit sold by BMS! Will post with findings when I receive it.
I used a generic “J” pipe that I bought off eBay, it required some modification to get it fitting how I wanted.
