Cool can installation
 

Hey Guys I'm installing a new Aeromotive fuel system in my car, and this system runs a return line from the fuel pressure regulator to the cell. I was wondering if it is legal to run the cool can inline with the return line. Thanks in advance...

I think that is a great idea. There is nothing wrong with the rules either.

Todd, It's a very "grey area",and one a few racers have tried to get around. I've actually seen it on 2 cars in the last 2 years......If only the return line passes thru the cool can,you would be artificially cooling the fuel as outlined in Section 19, 1.5 fuel systems......,subject to the Tech Officials interpetation ,personal beliefs or lack of sleep the night before!.........Tom

Todd mount it in the trunk if you can... Pro Stock dose this

Re: Cool can installation
 

I'm pretty sure all Pro Stocks have front mounted cells. Plus, aren't they specifically prohibited from using a 'cool can'?

Re: Cool can installation
 

Please explain what the advantage would be if your
running the return fuel line through a cool can?

I understand the idea of cooling the fuel before it enters the carb.

Re: Cool can installation
 

Returning it to the fuel cell and cooling it is going to do squat to improve HP.
You need cool fuel at the carb/s, not back in the cell.
Cool it between the cell and carb/s. However, with a deadhead type regulator, this in itself will heat the fuel as it can be sitting there. A front mounted cell or front mounted 'second' cell is what we'll be putting in ours, with a return type system, which returns to the front cell and through a cooler.

Leave pumps run circulate through cool can. I heard WJ had cool can about 8-10 years ago w/liquid nitrogen would leave fuel pumps run had return line supposedly would get fuel to around 30 degrees. I think if you look @ Pro Stock rules I think they
are'nt allowed fuel pumps with return line so they can't circulate fuel to cool it.

Great idea but not legal in S/SS class which is what the subject here is about. One fuel tank or fuel cell only per rulebook.

The reason I like the idea of placing a cool can at the rear of the system is I believe it may cool the fuel down without the flow restrictions you MAY have with a cool can (I'm talking traditional store bought item) at the front of the system. I see the rule book allows for a cool can. It does not say were it has to be. Front or rear, it's purpose is to cool the fuel and I see that as being an allowable modification.
FYI - I've run a cool can with a return line fuel system. I have personally found no benefit to a cool can with this system. I think the return style fuel system in itself cools the fuel more so than a one-way system and that amount seems to be adequate.
That's just what I've found. Good luck and hopefully you find some free HP.

Hey!! :D

Re: Cool can installation
 

toyota years ago went to dead head fuel systems in their vehicles.
they believe that fuel returning to the tank is heated and heats all the fuel, then changinging the emissions and character of the fuel, bringing down the power of the engine, and increasing emissions. they use a stepper style pump, based on throttle valve openning and load on engine to adjust fuel pressure needed.
I personally like the idea of a cool can on the return side cooling the fuel in the tank thus cooling the fuel being delivered.
I've also heard of dry ice in the tank, thanks ed o'brien for reminding me. but don't know how it affects the fuel, doesn't it smoke out then, thats my question. sure would cool it nice tho.

Re: Cool can installation
 

Dry ice in the fuel cell will change the dielectric content of the fuel. As the dry ice evaporates the CO2 will, to some degree, go into solution with the gasoline inside the tank. That can throw off the readings on a fuel check. If you still intend to do this just remember that there will condensation in the fuel cell. Your are diluting the fuel again and this will change the dielectric and you will be running H2O plus the fuel.

House of darts, I saw dry ice put in fuel at Topeka national event, class run off in super stock, must have passed fuel check, because he won class. Tom

Re: Cool can installation
 

OK, from first hand experience:
A number of years ago in my SS/BM car, I built a cool can in the trunk on the return/bypass side of the pump.

Was told by NHRA tech to take it off. There is a rule (written or un-written) that says the cool can must be in the supply line and within a certain distance of the carb. In the engine department.

I thought it was a good idea, and I believe it worked too, but it went away.

Bruce Bacholder told me today that the fuel pressure regulator and cool can have to be at least 6 inches FOWARD of the firewall. SO that ends that. Thanks to all who replied
