what are your thoughts on the dry sump tank inside the car next to or behind the driver in a sealed compartment? legal or unsafe or what?
-
I think it just has to be secured well---lots of folks put them inside.
-
Closer to the pump the better. Tony

If you're going to do it run a line from the vent to outside the driver's compartment. I really don't like the idea because it's a relatively heavy item that if it comes loose can be lethal as well as the fact that a hot oil bath doesn't do a lot for the complexion. :evil:
While I say that I have done it on short track oval cars where the crashes don't tend to be so violent and the tank is well protected being inside the car.

all very good points. think i might see about making room in the engine compartment. if too tight then i'll think of another spot.
-
Hot oil is extremely flammable. Best to keep it out of the drivers compartment if possible.

i agree. i was thinking if i had to put it inside the car, it would be in passenger footwell in an enclosed compartment. like nascar does only they do it behind driver seat.

The better tank shape is a tall, narrow cylinder - tough to have enough volume, and still mount it there.

can you please tell me why a tall tank is better? i was planning on at least a 4gal. but prefer a 5 gal., that WOULD be very difficult in pass. footwell.

After years of messing with a tank I built for our modified roadster that was theoretically correct, I broke down and bought a 4 1/2 gallon Peterson tank on eBay for a song. The difference a professionally designed and built tank made was night and day as far as de aerating the oil. Tall, multiple baffles, swirl inlets and a stand pipe up the middle make it work. Be sure to follow the makers advice about vent tube diameter and routing.

Jim,
That sounds like a Patterson tank, I am not familiar with Peterson tanks. Are they another manufacturer?

Remember your pan design and your pump design is going to be very important also. What style of pump design are you using? How much vacuum do you want to pull? Are you going to have an air separator? All questions you need to answer before designing your system. As Dynoroom mentioned, if you run an air separator then you could also use a non round tank. This is a Honda F1 tank I have for another car and its designed for a small cavity of the car and holds about 6-7 quarts. This should give you an idea of other shapes that could be used. Tony

well the bullet i bought has a weaver 5 stage pump and the pan is on the engine. i haven't picked up the bullet yet so when i do i'll have spec sheet and will be more informed. the bullet was a spare for the macdonald and pitts 98 firebird. so i know it's a good piece. what i'll probably do is copy his oiling system but Tailor it to my camaro. i've decided on a 1972 camaro for my aSalt. :-D

Great advice, building a tank that does what it is supposed to , number one job of the tank it to separate the air from the oil, and the tanks built by Peterson and others do a great job of this. The high tech Honda pan that Tony showed is good if you happen to have a multi-million dollar engine development program but not many of us have that ability.
