There are a lot of factors. Fuel pump arrangement, how many pumps, e85 or gas, return system or not and a huge factor is G-force. When Billy is making a run the fuel is probably damn near up against the back wall of the tank. And when I have starved mine I was pulling over a G in the corner.

Running the car with low fuel isn't the best ideer no matter what though.

Not as scary as a triple pump return system on e85.

That car is way to pretty to be that fast. In a good way.

What single pump are you running?

And that supports 680 rwhp?

Okay, I am running twin 465s with a 255 that comes in at 15 psi, I can fill a jug in no time.

Nice pic.. and motivating lol. You using sub-frame connectors? I need something with my vert and thinking bmr weld-in

 

[muztangman93]

Id like to go with twin 465s and id1000 injectors and run some e85 hopefully spring time I can make it happen but now Im a bit worried. Plus my car is running great but my passenger side breather always had alot of vapor coming out and the drivers side had none well now I see just a little coming out of the drivers side as well.

3/4 tank at the track and you are good. That way both sides have fuel.

Yes, I have the BMR weld in. Once the Anti swap bar is there the car will stay strait and stiff.

Don't you have a cage? I'm not thinking frame connectors will do a thing for a car with a cage.

well, just so you don't feel left out.. I just broke my tranny

Now the bad news.

I hurt the motor. Later after those runs above I made a pass with only 3/8 of a tank of fuel in the car (that I think was on the pass. side) and starved the motor on the big end. Car pulled a 1.39 60 ft and a 5.94 1/8 mile at 117 mph and nosed over some on the top end so I backed out of the gas just as my warning lights came on, meaning I was below 39 psi at 24.9 psi of boost. I went back to the pits and fueled the car and all seemed well. I should have pulled the plugs though since I starved the motor for fuel. Next pass out, same 60 ft and 1/8 mile and then just past the 1000' mark the smoke came out the pipes., I need to pull the motor later and see what the damage is for sure though. Since the plugs where melted across the board, 1,2 5,8, I am assuming my diagnoses is correct.

I know this for now. The car was low on fuel, I have 4 melted plugs and oil in several cylinders.

Very stupid mistake since I am the one who is always reminding people about the pass side tank issue on these cars when changing out fuels and running with the tank low at the track. Hell last week at RPR I even pulled the pass side senor and removed the fuel on that side just to be sure of how much fuel was where. I really want to half the tank or add a fuel cell this winter so this can never happen again. For now I will fix it and run no less then 3/4 tank at the track so I know the pump will always have fuel.

Wow, Im sorry for the both of you guys. Truly horrible news. To be honest, I am still gun shy and everytime I go to "Little Mexico" and make a run. I keep my fingers crossed it stays together.

Wow, that sux.

I was always under the impression that with a return system that the DS of the tank filled up first. That is where the fuel returns to and what fills up first when you fill the tank through the filler. What am I missing? I may be playing with fire and not know it.

This is a good point, I guess there is a good side to running 3 pumps at all times. I hopefully keep the drivers side full 100% of the time, even when gauge says I have 1/4 tank I should have 1/2 tank on drivers side. I guess Im lucky cause I always use 1/4 tank as my benchmark for not getting into boost.
