Fitment with Synapse CP and VRSF 7.5"?

Hi there,

i recently ordered me a VRSF 7.5" FMIC, which is about to arrive mid Jan.

Since my car is a 2012 1M, i knew i had to order with the "lower cp upgrade" (which was included anyways).

Now i just got to look about the differences in the oem cps, and that what i found:
http://www.evolutionracewerks.com/si...serialNumber=2

Now this is where my curiosity starts:

Most aftermarke chargepipes feature a rather "short" design:
https://www.ftpmotorsport.com.tw/pro...54-charge-pipe

Evolution Racewerks offers a shorter or longer design, depending on build date (which makes sense to me so far):
https://www.x-ph.com/evolution-racew...e-bmw-135-335/

Since i have the synapse kit installed, im also running the cp that came with the blow off valve, which also has the long design, as you can see here:
https://www.vividracing.com/catalog/...150705288.html
Thats how it looks installed in my engine bay:

Note that the coupler from oem fmic piping to chargepipe runs straight, not angulated!


What i dont get at this point: With the piping of the VRSF 7.5" lower cp upgrade, will the piping interfere with my upper chargepipe, since it is the "longer design", or will it work, fitment wise?

Thanks for you help

Max

The race intercooler has a 3" outlet along with a 3" lower chargepipe connection. Your synapse chargepipe is 2.5". Right now your chargepipe is a bottleneck but you can use a 3" to 2.5" coupler to mate the intercooler to the chargepipe.

Alright, so im going to look for a 3" CP that uses the original clamp mounting at the throttle body and supports a flange for the synapse BOV. (And also has the flange located in a way that allows the mounting of the Synapse BOV, which is rather big, compared to tial bov)

You can use an adapter to go from the HKS to the Synapse. We have a HKS chargepipe on sale right now

Is that adapter being welded in? Cent seem to figure it out how the adapter would be installed exactly.

It's clipped into the BOV flange but can be welded if you'd prefer.
