this is probably more of a question for the AA/G guys , how much gasoline is used for a full 5 mile run? thinking in the extreme sense. 5 gal? 6 gal? trying to figure a safe fuel cell size. i don't want to carry more than whats needed............plus a pinch more for those extended starting line waits. :? :? :?
-
Nothing says you cant put 5-6 gallons in a 10 gallon cell if you have the room, and fueling up and resealing is a pain.
I say go as large as you can fit.

Jonny beat me to it...
You might want to consider carrying enough fuel for qualifying and return; just so you don't have to deal with re-sealing the tank every time in impound. 4 hours can fly by…

i really like the way you think josh. now thats positive thinking. i do anticipate a trip to impound. :-D :-D :-D :-D :-D :-D and one less thing to do can be key.
-
We average less than 4 gallons per run and had a 16 gallon cell in which we ran at about 15 gallons full paranoia about running out on a back up run ran rampant :-P
ps. this was with 900 hp on gas
-
We actually have run out before with a 6 gal. tank. We now make sure it is full to the brim every run.
-
I have a 20 gal tank, usually buy 10 or 12 gals of fuel. My car is EFI and uses only about 2 gals per 5 mile run.
-
and one less thing to do can be key.
EXACTLY :-D
-
ok, you guys convinced me. i'll go with a bigger tank than originally thought, and think back-up run. no need to add fuel. i'll carry enough for two runs. i'm thinking a 12 gal cell should work. any thoughts?

This Bonneville thing is pretty easy then, huh?

as easy as winning the lotto
-
I run in the AA class and my car has a 8 gallon cell, with a warm up and run it takes just over 3 gallons. I like to fill the tank until it just covers the foam a little. If you have your gas can filled you can have it sealed too and just have a official watch you pour it in the tank. Thanks

Haha! Glen, that's what I was getting at. The comment just came across sound naive!
Anyway, good luck BalsaSalt.

Is the fuel truck open before morning record runs ?
-
Yes, but -- A: you don't have much time. If there's a lineup you'll be sweating bullets. I think Rick opens the fuel truck around 6.30 or so, but if there's a line (see above). And since you've got a requirement to be in the line/parade going to make return runs -- you're not allowed to hang around and say "I'll catch up with you later".
I forget what I was going to say for "B".
-
....and "B" -- in that melee you might have a hard time in the dark to find someone to oversee the fill-up in Impound.
-
This is one of those enlightening threads that makes this place great for a newbie like myself. Several good points made (and taken). Thanks. :cheers:
-
You might think about "what if I want to run fuel" in the building process. I am on my fourth tank and it will be big enough I hope!

That's exactly why we went with a 20 gallon tank. Doubt we will run fuel, just run in the fuel class. :cheers:
-
the only time you can have too much fuel is when you are on fire
-
I believe Stan is mistaken about difficulty in finding some one in the impound to assist with the refuel, reseal process.

You got that right :-P
-
Dan --
You're probably right -- but . . .
Why take the chance with everything else you got to do in the limited time in the morning when you've got up to 4 hours the previous evening?
Stan
P.S. I love your new orange cover!
-
Cover color chosen by Judy and Bob Sights. My thanks to them for all the help.

Mine is a 496 BBC. Uses about 5 gal on Methanol. About 8 on 25% Nitro. 11 gallon tank.
Its not just about running out, its about whether you like inspection ports in your pistons............. I know.................. Bob
:-o
-
So, after reading all the replies I think a 10 or 11 gal will be good for our lakester. Are the Poly fuel cells ok? Waiting by the mailbox for my rulebook!
-
Hope the box is not outside. I hear they won't go out 'til the 1st of the month. For your sake, I hope I'm wrong (as usual).

We have been running at Bonneville for 40+ years now...... we are usually very careful about making sure we have lots of fuel. Until we needed to make a water tank out of our original (not stock) fuel tank, we had a 30 gallon tank in our Vega.... It did NOT run out of fuel..... We now have an 8 gallon fuel tank and it is always a worry about whether or not we can make two full runs with warmups and all. If the tank is full, it will...and we have never run the Vega out of fuel.
The lakester now... it has a 10 gallon fuel cell .... we fill it quite full as well..... the first year we ran the lakester, we were licensing two drivers.... we had got the second driver up to a 190 mph+ B License run.... we were doing laps on the short course on Friday morning .... and .... someone's (NOT mine) "famous last words" .... "We are only running for 3 miles and not at full throttle- SURE it will make another run!!!!"...... well he was coasting at the 2 1/4 mile at 185 mph.... and we ran out of time to make that A License pass....
So, even with a big tank keep watching the fuel consumption.....
There is one other thing I must add..... and another case of "famous last words" are part of this one as well.....(it was the same "someone" as well) If you are running in ANY GAS CLASS- unless you know that you are only doing license passes or your engine is 300 hp or something under what it will take to set a record- GET YOUR TANK SEALED! .. with the Vega back in about 1999 or 2000..... (here come the words).... "NAW....NAW.... The car won't be able to qualify for the record.... we are just going out for a test pass!".... the record was 237.833 mph..... the car went 240.959 mph!..... WITH AN UNSEALED TANK!..... the next run would have made a record 2 way average..... but was short of being a qualifying run (at about 234.950 moh)..... and we hurt the motor bad after that.... It took until 2003 for to set that record and get our third team member into the two club.....

Sparky.... I have been meaning to ask you.... 900hp on gas.... was that in your lakester on your way to 300+ MPH?.... Specifically, did you go over 300MPH with 900 horespower?

I have been meaning to ay something about this one for a while.... It is easier than winning the lotto.... way easier..... especially if you compare the fraction of one percent who hit it big playing the lotto in comparison to the tens or perhaps hundreds of millions of people who sseriously play the lott worldwide.... I sort of think that, if a 200 MPH Club hat is the big prize, on a per capita basis your odds of "winning" at Bonneville are thousands of times greater.... now, DON'T go comparing to dollars spent though!.... cuz a $2.00 lotto ticket, compared to the hotrodders equivalent in spending $2.00 in real money, won't even get you a rule book.... and of course, with the lotto, it IS mathematically possible to get the big prize with just one ticket - purchased ONLY ONCE in your life too!
-
actually your chances of getting in the 2 club would improve greatly after you hit the lottery :roll:
:cheers:
-
I think the second hat's only $10 or $15.
Stan
-
yep, we got that butt ugly RATICAL Lakester a little over 3 with a little over 900 on gas

I cannot argue with that! :-D

and then you can see yourself on one of those TV shows about the people who've won the lottery and then went broke :roll: :-o :-(

I knew a woman here in Tucson who won $200k back in the '80s. The money destroyed that family; it was a curse for them.

The book "Performance Automotive Engine Math" by John Baechtel gives the formulae for figuring out fuel consumption. It is in print.
