Dry Sump Oil Lines and Firewall/Flywheel Protection
« on: July 09, 2012, 02:34:34 PM »
I've heard various opinions on whether or not one should protect oil lines through the firewall with an 1/8" steel tube/box in the flywheel area.  The rule book does not say this needs to be done (only fuel).

Couple Questions:

1) Is there an official position on this in relation to rules/regs and inspections?   Last year we did not run the dry-sump setup, so it was not inspected/passed with these questions in mind.

2) What is the practical answer and for a car with a billet steel flywheel and an SFI scatter shield, should I be worrying about it?

Thanks as usual . . . see you on the Salt!

Dale, as I pointed out earlier today, there is no provision for it in the rulebook.Our setup conforms to the rulebook in every way.

Are you sure you want to open this can of worms? :-o

See you in a few weeks! :cheers:

B & S, this should be directed to the rules committee@ SCTA. I would run the lines thru a steel tube if I was running them past the flywheel.

I forgot to mention, that in addition to the sfi bellhousing, the car has an 1/8" steel floor.

This is a good example of how downloading the tech inspectors sheet from the SCTA web site can be of help. This is the sheet the inspectors use to do the safety check on your vehicle. If you go down the list and check off all the things the'll be looking for you'll have a much easier time going through inspection.

Mike, that's great advice!

I have several printed off here at the house, and refer to them when I'm working on the car.

Yeah, the tech inspectors sheets are really a good help in the build process.   Buddy had one last year and we used it like an addendum to the 'Build Bible'  (Rule Book) - it  really was an aid to us newbies

I'd protect my brake lines as well.

We had the room in the truck to run all the fuel and dry sump lines through a piece of 1/8" wall rectangular tubing that we massaged to fit in next to the bellhousing and bolted to the frame. We just figured that we had the room to do it that way and chances are the rules would eventually want any oil lines shielded too. It's a tight fit with 2 -8 lines 2 -12 lines and a -16 line.

The flywheel protection rule is nice, but unless you run line isolators on your fuel and oil gauges, in the event of a catastrophic incident those lines can rip out dumping fuel and gas in the drivers compartment. I have had first hand experience in a road race car. Tony

OPP'S I know it's for fuel  but I believe it's used for all others too..........Probably not mandentory since the new phase at the begining of the book

Rightfully the best rule in the book is the first one.  :cheers: Tony
