Where is the New Superior Sump????

[SHORTRV7]

I called Superior about a month ago and ask them when could I expect the new sump that is to replace my Ryton Sump. They told me it would not be long and they would be handing them out in the order of your purchase which seems fine...... But when, as I am starting to hang my engine and want to get it right the first time.. Has anyone else heard any news on this??? I will be calling again tomorrow..

I built my engine last October (06) with the Ryton sump, and they stored the engine there for me until I was ready to hang it. I had them send it to me this past August (07), and it came with the new sump.

Does it look like it will hold up in a backfire situation? How is it different?

Here's a couple of pictures of the new sump. I was at an engine install this past weekend. The new sump is really nice! It should provide additional cool air since the induction is virtually separated from the oil sump.

Yes it does. The sump is cast like their engine casings.

I believe the majority of the difference are internal, with the added ability for a blow-out or by pass in the even of a backfire. I really didn't get to put the two side-by-side for comparison. If you call Superior and ask to speak with Pete Whitaker, he can tell you everything you'd need to know.

I fitted my new sump this week.

It wasn't as striaght forward as I first thought. I had 4 problems.

1) the exhaust covers the sump drains

2) the exhaust is too close to the snifal valve

3) the inlet pipe for no.1 cylinder now conflicts with the exhaust heater muff and pipe routing

4) The extra opening in the sump on the front left corner interferes with the mixture bracket

To solve the problems

1) I had to use the side drain at the left rear. As I plan on fitting a inverted oil system I asked Superior to check that a 810-S Tee would fit in this location. They tested it and found to do this you have to remove the manifold from the sump first then then fit it.

2) I used an An915 45 degree fitting to move the snifal valve away from the exhaust.

3) I had to reroute the heater pipe, it does fit through, but is quite tight compared to before.

4) The bracket I had to move up above the crankcase sump joint. It's higher than before and the angles aren't as good but with a bit of work I managed to get full travel in both directions.

I'll try to post some photo's showing all this

My conversations with Superior last June, they had the new sump cast but it would only fit the 7 and not the 7A.
They began shipping for the 7 only and expected the new casting for the 7A would be available in September. I've still not heard from them. Can't understand how it could get casted incorrectly. You just take the old cast and make it the same size. Right?

I had to replace mine due to a leak and replaced it with another ryton.
I've had no problems since I replaced it. I don't expect to expedite replacing the new one until I have too.

If you note the photo's of Rocky's they are a 7A so I'd suggest you talk to superior.
The new sump is much better and stronger although the penatly is it's 4 pounds heavier.

In looking at those pictures, I see some rather large mounting bosses on the bottom of the case above the fuel injection unit. These bosses look unused and rather beafy. What are they for and how much weight do they add?
