Hi all,
Has anyone fitted one of these?

Says you have to drill and tap your gearbox.
Are they a good addition to an engine?
Thanks

What is its purpose?

It keeps oil in the sump instead of it being thrown everywhere by the crank and gears.

I have to say I would imagine camshaft wear to be quite rapid, especially with high lift rockers and how would one successfully bed in a new camshaft with a tray fitted ?

[Steve220]

Easily. Cam followers are oil fed from above.

Buy the guessworks item, much better

The cam lobes won`t be getting a decent amount of splash lubrication from the crank that is essential for the first 20 minutes to bed a new cam in ( 20 mins at 2000 rpm ) and considering how quickly a cam gets knackered with high ratio rockers starving it of lubrication for no great gain doesn`t seem to make a lot of sense to me.

 

I`m just wondering if its a bit of a gimmick with more cons than pros unless used in a drag car to gain a fraction of a second on a quarter mile ?

Every day is a school day so just wondering, not arguing  :)

I’ll take a look. Have you got one?

Info on how to fit the GuessWorks windage tray. Should be similar but may not be.

My cam is already run in and I don’t use hi lift rockers.

Thanks Nick, I’ll take a look

Is it not to keep the oil in the sump when you tipped the mini on its side?

The cam should be covered in cam lube, which should give the cam chance before the oil comes down from the head. Plus the crank spins the wrong way to be 'splash' lubed.

nope.

It is to reduce the oil fling from the gears onto the crank and other moving parts. Hence the name windage tray.

Also note the last cars with the tall diffs have issues with excessive cam wear due to lack of oil splash onto the cam gear.

Race car part more than road car part.

I'm just trying to understand it all here.

 

Isn't oil supposed to get thrown everywhere, so all the parts get lubricated?

 

Sorry if its a stupid question, but I just want to understand how it works
