Thread: Change of pace

you do realize that talking 26-2700 lbs and a 26 fuel cell that your weight will change by almost 10% from full-empty???and that will shift handling so far that ----------I would use a much smaller fuel cell

Like Jerry says, the 26 gallons of gasoline is going to weigh right at 155 to 165 pounds depending on the specific gravity of the fuel you buy. That's quite a bit of weight for that size car. The stock tank was sixteen gallons, I believe, which is a weight change of 96 to 102 pounds. The tank is formed to fit on top and ends, too. Have you looked at the space a 26 gallon tank will require? What's pushing you to the big tank?

I will be daily driving the car while I build a budget Cummins powered 70's Ford f250, and I didn't want to fill it up every other day. The fuel cell isn't set in stone yet, the chassis is off to powder coating soon. I guess I could go with a 20 gallon one, but I feel 16 just being too small. Either way the 2700 lbs was including a full tank and my self, so I guess with an empty tank and without me I'd be hoping the car weighs in at around 2400 lbs. I'm just guessing though, I haven't done any test weighs yet. Last time I was able to go home and look at it, it was in the state shown in the picture.

I'd suggest figuring the longest course you'll be running, and the maximum number of laps you'll make. Estimate your fuel mileage, size the tank accordingly. Having a lesser weight on fuel means less compromising you'll have to do on chassis setup to make a run. I've never liked having to add ballast to a car but in competition it's sometimes just something you have to deal with to make weight. I'd prefer ballast over having to run a lot of fuel to make weight, at least you can put the ballast where it will do a bit of good for the handling.... SCCA and even some outlaw tracks still like to spot check cars after a race to make sure they still make minimum weight. I believe this was brought about because some teams "designed" ballast that would somehow fall off the car (usually on a hard turn) during the course of a race, making the front to rear bias remain equal as the fuel weight decreases....Certainly nothing I would have ever tried back in my twisty turny racing days!!!!!!!

The only issue with that is I have no idea where I'm going to settle down when I get out of the military. I can always rework the car to make it more of a weekend tracker instead of a daily driver.

Heck, might as well go with the big tank then, no law sez it has to be full!!!!

I'm new here also and I just wanted to extend a welcome from one newbie to another. Yes it does seem like a nice place to hangout and network.
