One of the ideas I'm considering involves running engine coolant tubes through the passenger compartment of my truck. I want to have the heat exchanger in the bed of the truck, and the engine is in the front. There's not much room to run the lines under the truck, so I'm considering running them through the passenger compartment.
I would use 1-1/2" round steel tubing as a carrier for the coolant, with the tubing being sealed tight at the firewall and rear of the passenger compartment.
I don't see any rule-book prohibitions about running coolant lines through the passenger compartment. If I'm missing something, please point me in the right direction.
As always, help/advice/precautionary tales are welcome.

Steve, I am kind of going through a similar issue with my lakester. Lee Kennedy says we cannot run any fuel or coolant lines through the drivers compartment so I am not sure if the passenger side of your truck is considered the driver compartment but would guess that it is. My lakester is a single seat and have separated the driver compartment from the rest of the chassis via aluminum panels and a sub frame, i.e., a space created between the driver and the chassis. No word back from Lee on the legality of this but there are few options when routing fluid from the front of the car to the back. If you hear something from the SCTA tech committee on this subject, I would be most interested.

Steve, I would expect your truck has hollow sill's separated from the inside of the vehicle that you could run the plumbing through.

That's a cool idea! I need to do a little poking around to see how much room I can find.
-
just wondering, could the intercooler or say a water tank be located in the driver's compartment?
I don't see anything in the rule book either.

With that much water volume in the plumbing you might need to use both sills to balance the weight & don't forget to put in a drain plug so you can get the $hit out! :-D.....Woops! Had to modify my profanity. :-D :-D

Make your own sills. Whats wronk with running a sealed box on top of said steel coolant lines? Drill some hokes in floor to allow escaping coolant to esacpe if so inclined, but seal passenger compartment from putside and lines, such as sills would allow.
Or, modify tunnel to,make it wider, run,tubing outside compartment and be done.

Great ideas, guys. I spent plenty of time searching for ways to route coolant lines, fuel lines, exhaust, etc. I think that using a piece of large-ish square or rectangular tubing (maybe 6x6), I can in fact make my own sealed "sill box" to house the coolant lines.

Remember rule 1.A gents. Don't jump thru hoops or over-engineer your car for rules that don't exist.

cannot run any... coolant lines through the drivers compartment
The nanny state is everywhere.

So, how much shielding needs to take place in the drivers compartment? Does it have to be through round or rectangular tubing or will splash shields of aluminum do? My single seat driver compartment is fully lined with aluminum sheet but is not fluid tight. I will run water lines down one side and stainless steel branded fuel lines down the other. I wonder if this will satisfy tech?

Where in the rule book does it say you can't run coolant lines through the cockpit? There are lots of roadsters with the coolant tank adjacent to the driver.

Maybe you should ask if you want to be sharing the cabin with what could be super hot coolant

I didn't say it was smart, just not prohibited.

My water lines run through the drivers compartment. They are -10 Aeroquipt Strat-O-Flex used in 747 over water life rafts. They hold up under the pressure of a black powder charge going off and blowing the gasses into the raft to inflate it. I suspect they are pretty good hoses. And the price was right. No one has questioned them yet. But things change sometimes.

You mean like this... coolant and fuel hoses through the steel tube and exhaust pipe with header wrap under the stainless shield

Yes, like that! Very nice work there.

The only place in a 2016 rule book that requires a watertight and flame resistant barrier is at the firewall (3F). Nothing in the book states water lines cannot run through the driver compartment. All fuel system components are to be "isolated" from the driver compartment (3I). So, how is one to interpret "isolated" for fuel lines? Will splash shields do if not required to be watertight? I was told that even stainless steel braided hose and AN fittings are not enough. These lines and fittings must also be "isolated" from the driver. The reason was if one of these components fails in a crash, fuel may find its way to the driver. I am still a little fuzzy on this because in a crash, stuff goes everywhere, including the open sections of the driver compartment. Are we to "isolate" the driver completely? I don't think that was the intent of rule makers so maybe simple shielding will be acceptable. Comments, please.

Steve, since you're running a turbo diesel with a swillion lb's of boost, you run the risk of shoving that into the cooling system via a head gasket failure. What ever you do, allow for that scenario.

Good thinking. For this year, I'm staying with a conventional radiator in front (no water-to-water heat exchanger in the bed). That may come later, but I need to be careful with allocating my time at this point.
So far, on the 2 occasions where I have lost control of where the swillion pounds of boost are going, it has only resulted in blowing all the oil out of the crankcase, a couple of melted pistons, 2 ruined cylinder heads, a ruined turbo, and a bunch of other expensive stuff that I've blanked out of my mind.

The sign of a true racer Steve. Well done. :cheers: :cheers: :cheers:

isolate means keep away from as in not be in. so, there shouldn't be any fuel lines in the drivers compartment. pretty easy. coolant lines are NOT restricted from being in the driver's compartment. original roadster i drove had water tank immediately behind the driver with normal rubber radiator hoses - never a problem. current roadster has radiator in a tank right next to me and has coolant lines running through driver's compartment. again, no problems. rule book gives min safety requirements. you can build beyond what the rules require.

Got it but my steel braided fuel lines do not run in or through the driver compartment but there are two small areas where the braided hose does run by but outside an un-shielded part of the footbox. So, the fuel lines are not in the driver compartment and are kept apart from it. Because these lines are not shielded from the driver compartment at these two small areas, it was suggested it may not pass tech.

The statement " you can build beyond what the rules require" is valid, however there is a clinker in the fact that it can't give a performance advantage, weather real or imagined, This is up to the discretion of the inspectors .
