Fiat 124 BC 2 liter 16v dry sump pan

[Nathan]

hi Guy ,

I currently race a 124 BC with 2L 16v motor. It produces 175hp at the wheels. I am currently attempting to build a dry sump system for this car.
At this stage i am looking at making the pan.
I have attached some pics of a quick template of what i am thinking it will look like.
I have seen a sump very close to this design work before but with only one oil pick up. i am going to have two oil pick ups.
Any words of advice would be great or even some pics of pans you have made would be great too.

thank you Nathan

Nathan, hi

Sorry I deleted the photos and never got to putting this in. Anyway, twin scavenge is always better for a large-ish engine like that in RWD instalation. I've done this several times see GC book P159 if you can, schematic below shows how you need a recess in the channel to clear the crossmember by 5mm or so.

The windage tray that collects the oil needs to be full-length and space is tight, you may need to raise the motor a few mm.

You can download 'Pixresizer', that shrinks photos admirably, I use it a lot.

Hope this helps,

GC

hi guy, after i had a look under the my race car with the block sitting in postion i fund there is no room for a second channel section due to the rack and pinon streering.

so it looks like the only option is my first design.
thank you Nathan

Nathan, hi

FWIW you can put twin scav just in the front, I have done that with 131 sumps, the rectangular oil channel then being quite short, only as long as the original sump oil well. 1 pickup goes right at the front and the other at the extreme rear just fwd of the cross member.

I'd be a bit cautious of using single scav.
