Show me satanic details...please.

The splitters look somewhat off to me also but they solve the high speed tracking issue.

Some from RR5. Cool VW logo on 550A trans case. Did a series on all the different number 'lighting styles from years past'

aren't those injectors reversed?

Nope, the left is a '911 RSR' (BOSCH pn DV0460), right is just a 'street' injector we used for comparison (shows cross-section). The 'floating needle' design is the same used in the common 911 street fuel injector. Pretty cool needle assembly for the RSR!

Below are two photos showing the fuel spray pattern comparison.



I also wanted to mentioned even though both the RSR and 911 street injectors externally appear the same, the part number clearly identifies their internal mechanical differences.

Here is the same area on a 550A Spyder transmission that I rebuilt a few years ago.
Porsche used modified VW "splitcase" transmission housings for all 356 and 550 models until late 1956.

The black ones are stainless steel under thin but sturdy conveyor belt rubber. The rubber is about 3/4 of a inch wider to act as a bumper in case of bumping a concrete parking block. I use a strip of the same rubber for the aluminum ones to protect the paint on the bunper.

9/16
I have added a middle section to it goes all the way across and made the splitter a little shorter.

hold up; what is the one on the right, then? what application for that stubby body?

love this.

The stubby-body fuel injector on the right in that photo is a "Mercedes" unit---that said, it is also the same internally as a 911 street fuel injector. The MB injector was used in the pix only to show the cross-section of the 'floating needle' design inside the injector compared to the RSR that's 'guided'. We didn't have a cross-section of the RSR to show. It was not the intention of my post to appear more on the technical side, but actually for the "Satanic Details" of the internal 'guided needle'.

PS: While on the subject... The 911 street injectors don't usually stick like the racing RSR injectors since those 'float'. The RSR injector, like a valve and guide in an engine head is 'guided' with a tight tolerance. When the fuel dries-up between the needle-guide and the needle, the RSR injector will stick. Truly a BPITA to get those parts cleaned and working again.

Thanks; learned something tonight. Appreciated.
