Hi !
Finally, after tens of hours behind the screen and in my engine bay, I think I have the right shape !
It has the same angle that the stock one has, so it must clear everything in the engine bay, it has the largest radius possible without affecting the fitting (larger the the stock one).
I added two ribs on each side to have a better sealing with the boots.
A groove in the mating surface to make applying silicon sealer evenly (I tossed the idea of using the Porsche seal, it's going to be just as good, but 4 times cheaper to make and change (20$ for the OEM TB seal...)).
I tilted the EVAP connector to be as close as possible to the stock location (do you know where I can get a new hose for this ? mine broke ...)
It's also 1mm thicker that the first one I made, so even stronger and resistant to heat (I will wrap it in heat shielding tape anyway).
It won't be black as the first one, but white. Why ? cheaper, and it's not the same black as the stock parts so ...
Finally, for information, nylon as been used for timing sprocket on some OHV engine, so in the engine bloc heat !
I think I will be safe in the intake
Oh and, it does not have the wedge but I can easily make one with a wedge !
Ffffff I'm really stressed to now if all my measurement are right ^^
