Dry sump systems Options

[moggy]

It's time I moved out of the dark ages and got myself a dry sump system on the rallycar. What's everyone using? Any pictures of installations? especially with the stock cooling. My concern is that I'll have to do some major surgery on the fan shroud (4 cylinder engine) as any dry sump pump will sit so far proud that I'll have to cut a hole in the fan shroud. Really interested to see what everyone has done. (IMG:style_emoticons/default/beerchug.gif)

Aaron - I looked at that option but decided against it for a number of reasons:

1 - The engine/gearbox needs to be really held in as strong as possible in the rallycar, all that heavy vibration and big hits really tests all mounting points out to the limit. For this reason I didn't feel comfortable only holding it all in on just the bottom 2 bolt holes

2 - With the vibrations experienced in rallying I wanted to have some kind of rubber seated engine mounts to absorb at least some of the pounding.

3 - I couldn't see how a straight bar was going to allow me to avoid the gear linkage.

For these reasons I went with the standard engine bar and modded mounts.

Last night I managed to find some good solid rubber machinery mounts that are ideal as engine mounts, they're even the same diameter - what are the chances of that eh? (IMG:style_emoticons/default/biggrin.gif)

Using the mounts I cut of the back plates last night, I offered them up and found a problem on the right hand side - it now knocks into the old oil filler blockoff as you can see (the engine I'm using to mock everything up does not have the blockoff plate on, as you can see, but believe me it knocks into it). This means I'm going to need to shave off about 10mm from the right side of the mount to get it to fit.

On the left side, all is well, although I'll still shave off 10mm to match the other side. Whilst at this point I checked measurement away from the backplate again to ensure it's all still at the smidge over 1 inch. Still looking good.

You'll notice in the above to shots that there's gap between the mount and back plate, this was from the amount of metal the cutting disk bit out when I cut the mounts off the back plates earlier in the process. To fill in this gap and to also add strength to the mounts in their lower postions it's necessary to weld in a small additional plate, as you can see below:

And here's where we're up to at the moment. All tacked up roughly. Offered it up to the engine bar. All fits perfectly. Next steps - weld up what I have, clean it up, maybe add another strengthening gusset.

That's all for now folks (IMG:style_emoticons/default/santa_smiley.gif)
