I was wondering where a person would mount a fuel tank. I guess with your system air flow through the radiator would not be a problem. I have heard some say it is harder to make heat than get rid of it.
Maybe by next year we can make some changes. Now if it would only look as good as what you have.
The front mounted tank has not caused any heating problems from the blocking air from the radiator. In fact I have blocked off the grille too - with no problems. Water temp of 170 to 180 when I get back to the pits.
I have seen a couple cars with a rear mounted tank and a small (2 gal) cell mounted in the front. The small front cell had a Holley float bowl mounted to the side of it. The driver fills the front cell with an elec pump, from the rear cell, just before his run. The float bowl will shut off the fuel when it is full. This way you can mount the small cell above the belt driven pump - no fuel draw problems this way.
I did a search to try to find a cell with the float bowl on it, with no luck.
I am assuming the guy mounted the bowl himself.
As far as making heat - it is pretty easy with the fuel shut off. The shut off actually diverts fuel back to the tank to shut the motor off. If you slowly move the valve the motor will lean out. I can get the motor to 200 deg. with this simple method.
I always heat the motor to 200+ when I shut it off for the last time after the race. I have had NO corrosion - rust problems since I started doing this.
