Dry sump tank location on LHD center shift car

[k wright]

Now that I can stop the car without flooding the carburator I've found that it needs a dry sump system. I can't see anywhere to mount one on the car, doesn't appear to be enough room.

Anyone been down this road before?

Thanks for your help,

Ken

I was just talking to Builder (Scott) about this recently, and he says it should easily fit just behind the rear-bulkhead (or thereabouts), next to the engine, which makes sense to me. ...depends on whether you have some customized (non-Factory) stuff residing there already though, of course. Scott should be able to tell you more than me, though.

I have both a dry sump system and an accusump, so there is quite enough room.

Check out my build site at www.craig-ultima.com which has alot of photos. Email me if you want specific info...

Thanks for the link. My shift linkage goes through the space that is occupied by your dry sump tank. I have a G50/52 transaxle.

Great looking car!

i think the 1000hp spectrum 5 racing car in the states had a dry sump and centre rod shift

Hey there Ken! Glad to hear that your enjoying the car and have got that carb sorted out. I remember talking to you a long...long...time ago about that issue and it sounds like you've come up with a solution to the engine dying with a carb fitted. Glad to hear it.
I've basically decided that my car should be a track day car and I really don't care to drive it on the street(which I never did much anyway (6 years and only 600 miles on the engine)).
I too am looking at possibly going dry sump with the next engine that I build. Finding a spot for that dry sump tank can be difficult with both fuel tanks in the side pods. A lot of the older race cars ran the oil tank in one side pod and a fuel tank in the other. I believe Palmer's Sports had a special tank made up that was mounted up front in the steering box area somewhere. These cars have about a 39%/61% weight split and anything that can be placed up front like that will help. It would also be a LOT of work to say the least. The factory can chime in but I've seen the factory cars, that do have dry sump tanks, mounted next to the transaxle(left or right side) opposite of the gear linkage. I've not had a problem with losing oil pressure with my accusump and a wetsump yet, but then again I'm really not a good enough driver yet to push the envelope. You've been tracking cars for a long time.
By the way, I need to get you down to Texas again for a track day at Texas World Speedway in college station! You'd have a blast.
Cheers!

The carb is absolutely bullet proof in hard stops if....you form a slosh tube with a high arch. Used a 3/8" fuel hose to connect the bowel vents together and cut a couple of vents in the top of the resulting arch.

I can slide the car to a stop on dry pavement and the motor keeps running.

I hope that I've remedied the oil problem by recharging the accusump. Thus far it's a go. If not I'll spring for one of those Moroso 6"diameter tanks and wait for 6 months for a custom dry sump pan that will fit an alloy dart block.

What ever you do, don't but a dart alloy block, standard small block chevrolet pans will not fit this motor.

If I drove this car to TX I would never be able to hear anything again.

Again, thanks for showing me your car, it looked great then and still does.

That's pretty interesting about the dart alloy block. I didn't know about that problem. I'm glad your having fun with the car though. Car looks great by the way!
Cheers!

How high is the arch.
I have fitted a similar tube but the arch limit is the available space under the air cleaner cover i.e. not much.

I've got one of the 6" air filters. It goes all the way to the top.

It works great.

[steve_D]

So I either get a bigger air cleaner or bring the pipe out through the top and back in again.

It will be worth it. You won't believe how fast you car can stop with AP brakes.

[arthurr]

I have a Can Am and have a Peterson Fluids dry sump tank mounted on the drivers side behind the bulkhead about one foot. It is not even a very tight fit. If you need pictures let me know.

[k wright]

I would appreciate photos. What capacity is the tank?

Thanks,

Ken

After a great deal of time on this subject I'm going with a dry sump system. The only place that I can put a tank on my car (LHD, center shift) is above the trans-axle. Talked with Weaver Brothers and Canton. Both say no problem as long as a ball valve is placed in the return line and it is closed while the car sits. Ferrari also placed the oil tank above the motor in the 355, this is why you have to start and run the motor and quickly after shut off check the oil level. Otherwise the "level" will read too low.

After tuning the carb up it is no longer the limiting factor on extreme stops, the wet sump is. I really hate to add all of this stuff to the car but it is easier than replacing the motor.

Again continued work on this; going with the cable shifter made by California Motorsports. Called them up to make the arrangements and found out that Roger Brown from Powerhaus II is now working there.

This is our dry sump tank location, on the driver side (LHD, center shift).

Since the LS7 has oil ports on the bottom right side, I will probably put the external oil system components over there too. It won't be too long now before I have a roller !!!!!!!!!!

Nice picture above!

I have the CMS cable shift, too. Ken, what shifter are you using? CMS said they are making one. I don't know if it's ready yet.

[k wright]

They are making a shifter for it now and expect to be done in the next 2-4 weeks. Is your transaxle in the car yet? If so what is your opinion of it (I know your still building)?

Thanks,

Ken

I hope the CMS shifter is ready in 2-4 weeks. That would be great. I too am hoping to get one.
