Re: Fuel temperatures
 

Ian, don't tell me you don't just run the AC duct into the trunk to chill the fuel. It is a stocker you run after all. right ;)
Are we any closer to a date for a sit down? let me know

Re: Fuel temperatures
 

I've looked in my rule book collection for the last several years and it does not mention a minimum.

I will be looking more closely at the fuel cell of my opponent from now on.Can you say starting line BURNDOWN? lol.

Re: Fuel temperatures
 

it would take you while for me, even with a one gallon cell. I run 1.2 to 1.3 under and only use 1/3 of the fuel in my system for a pass. thats driving up to the lanes late. Starting the car up everytime we have to move forward, burn out, staging last, 1/4 mile run, and driving back to the pits behind the junior dragsters being pulled back. so burn down as you may. i have found the quicker i go, the more effiencient my combo is the less fuel i use.

Thus the reason for the original question. Would lowing the fuel 5 degrees increase effiecinecy? i am far past worry about making horsepower, i am focused on reduced drag and increase effieciency. so far so good, but i am looking for more.

For instance - and no i have not read the rule book yet - maybe i can run a 1/2 to 3/4 custom made aluminum cell with fins on it to help it cool, mount it in front of the rad, run a total of 2.5 feet of fuel line and a really small electric pump. the weight savings should be about 6 pounds total. With the change going from 15 pounds in the rear to 9 pounds in the front i should be able to loose the wheelie bars as well (another 22 pounds). soften the rear shocks, stiffen the rebound on the front and.... well you know just bench racing really... i gotta go and start up the tig welder!

thanks

Ian

Ian, I think you'd best weld up a straight axle while you're in the mood.

Re: Fuel temperatures
 

I was a toyota tech for quite a few years and they eliminated the fuel return line to stop heating fuel in the tank. for emission reasons. I do not know if its the same for drag racing tho since the cars are not continually run and driven. chris

Re: Fuel temperatures
 

This may be wrong ..but isn't there some heat being created any time a fluid is moving? My point being a standing glass of water will freeze below 32 degrees F while water in motion will not given the same temp and duration. Is there a measurable difference between two similar fuel systems with different GPH pumps, and if so what measurable effect will it have on power output? Wouldn't a basic "cool can" negate any unwanted temp increase? Really I'm interested in any data gathered on this.

It really helps to put the cool can in the bypass line in the trunk only problem is NHRA ban it around 1988 when we doing it in Pro Stock!

Re: Fuel temperatures
 

NHRA currently bans any artificial method of cooling fuel in "most" classes now---some exceptions are the ET/Super and bracket categories---so that means no chillers/cool cans/aerosol sprays/ice cubes etc if ya can artificially cool it below the ambient temperature it is not legal--my understanding of the rules---comp

Ive put in a request to have this thread moved to the Modified and Competition Eliminator section....LMFAO!!!:D
