Check out this picture. See my problem?

I bought the Richard Sohn OMP Adapter from Real World Solutions thru Rotary Aviation. As you can see, it got installed while the engine was out. Now that the engine is re-installed, the air pump bracket and belts are making it inaccessible to attach a hose from the 2-stoke reservoir to the adapter.

If you are thinking I should remove the air pump, then I'm frustrated with the manufacturer/seller for not pointing that out before I bought it.

First gens and third gens don't seem to have this fitment issue; only second gens.

I bought it, I got it installed, I want to use it. And now with the rad hose installed, I can't even get to it to remove it and go back to stock.

Any helpful thoughts?

 

Make a bracket for the air pump that has a "U" shaped curve so you are able to get a hose on there.

RA probably didn't have an FC with the air pump still installed. They might not have known.

 

remember it was made for airplanes that dont have air pumps

 

But it was marketed and sold to car owners. Someone must have come across this issue before me?

 

can you change it to a 90 or 45 degree fitting and put a hose on it?

 

Quit conplaining. We are lucky to get any support these cars, so be thankful someone made a product to try to help us out. I'm sure if you called RA, they would have helped you out.

 

send them a picture so they can offer one with a 90* port on it. yes that looks hokey as hell for a stock fitment car and as a rotary product seller they should account for this. being that they sell through a rotary aviation website means little to me, in actuality almost 90% of the products RA sells if not more are sold for AUTOMOBILES.

i say this because i always take into account various setups when i make products and without feedback they may not know there is an issue.

but whining about smog pump removal is a bit overboard. it is the easiest accessory to remove, even easier than the alternator to get access.

 

I emailed Rotary Aviation, explained the situation and attached afew pictures. They quickly responded. I got feedback from their parts engineer. He said, try a 90 deg elbow. I replied that my mechanic and I felt it would still have issues with clearance from the fan and belts. They replied that they have sold lots of these and nobody has ever contacted them with a fitment issue.

 

You don't even have to remove the pump.
just remove the bracket and put a 90 degree fitting on and put the bracket back on.
Hmm..I wonder about this: get a smaller air pump belt and that would raise the bracket up?..so you could access that nipple?.

 

I wish things like this were the only hurdles to get by

 

i have to agree that they are right but they should acknowledge the issue and sell different kits for different applications or at least 2 different fittings with each. whenever you modify something you have to deal with space requirement issues, not everything is going to fit as copasetic as it originally did. a 90* or 45* should work but you will have to do some shoehorning.

 

Here is my creative solution

The original straight fitting was replaced with a 90 deg elbow. Actually, the elbow had to be cut back before being inserted to gain more clearance. Instead of flex hose, brake hardline was bent to curve under the braket, past the fan blades, between the belts and along the steering rack. A short piece of flex hose was used to connect the kinked hardline to the adapter. At the other end, I have more flex hose going up to my 2-stroke oil tank, which is actually an OEM coolant reservoir mounted to the left strut tower, which I modifed with a lower drain plug. (This stock coolant overflow tank was short lived in 1986, before it got redesigned and relocated to the front, behind the bumper.)

 

I'm wondering if it might not be easier to reengineer the airpump tension bracket.
It's hard to tell from the pics (and I'm too lazy to go look at my car) but has anyone approached it from that angle instead of changing the fitting?

Since you're relying on gravity feed, seems like the shortest direct path would be a good idea.

 

yep, if it were me i would have gone under and across the smog pump and mounted the tank to the passenger side but that method looks like it will be ok.

 

I called them and asked them if it would fit on a S4 turbo with and air pump and they did not know, so I didn't get it.

 

Weird, I have a RA adapter as well on my S5 TII. The nipple on mine is pointed downwards instead of up like yours.

 

My S4 has a mechanical OMP.

Correct me if I'm wrong, but S5 and FD have electronic OMP, so it is all together different.

But it is interesting you point that out. If the unit points downward on S5s, then the air pump bracket (as shown in the photo above) would not be a problem. Are you running the air pump, still?

 

perhaps they changed the design to avoid cavitation.

 

Well, my engine still sits in my basement, so I don't know if there will be any issues yet, but yes - I intend to run the airpump for starters.

 

Fitment is an issue on my NA S5. Still trying to figure out how to make it work. Not in a rich though since I don't have any aux port sleeves to actuate at the moment.
