High Downforce Rear Diffuser

[Marshy98]

Hi

Currently upgrading my SR3 to high downforce, when fitting the rear diffuser i have found it is hard up against the steel braded oil pipes that run from the sump, it takes some force to fit it, how i see it i have two options :

1. Leave it and see how it goes
2. Cut a slot in the diffuser with a hole saw and jigsaw to relive this area.

What do you guys think is the best way to go ?

1 - the pipe will eat its way through the diffuser, and when it hits the carbon it could loose.

2 - holes in diffusers are the best way to go imho

I'd look at a way of re-routing the pipes in some way or adding a spacer to the diffuser. More work but you can feel safe with the results

If they're firmly clamped together then they're probably not going to do much damage (as long as the hose isn't crushed far enough to restrict the flow). It's when things can move against each other that you get fretting problems. If you cut into the diffuser, the disruption to the surface makes it much easier for the air to detach. The further forward this is the more harm it's likely to do to the aerodynamics. ALl in all I'd be inclined to leave it as it is, but if it's accessible have a look in a few thousand miles time to make sure neither of them are wearing through each other.

Hi, If you cut a hole you'll lose downforce and negate the point of fitting it. The oil pipes run close but shouldn't touch, which one is causing the problem?

Thanks for the comments, not easy to reroute, i have attached a photo, its the return pipe from the sump to the oil tank.

Looks like you could do with a 90deg union on that hose rather than the 45deg?

...or a 60 degree elbow.

If you contact Matthew at Think Automotive (Twickenham area), he'll sort you one out to suit.

Yup, that should be a 90 union, you could get one from Merlin Motorsport. You can unscrew the blue fitting from the red hose end fitting, this will save you replacing the whole hose

Just realized, swap the hose round, that end goes to the tank!
