You're talking about a compound boost setup on a 15K+ car and you're worried about MPG? Stock tank is 15.7 gallons. MPG should be pretty danged dismal, especially if you intend to have fun with the car.

You're going to run twins into a whipple? What is it you hope to accomplish? Aside from a very hot intake air charge.

ok first off you are wasting your money going compound boost plain and simple you will have 3500+ in the blower and 7-9k in the twin turbo kit. what is your goal with the compound boost setup? high horsepower or just to say you have a compound boosted car? take the money that you were going to buy the whipple with and put it into a good set of pistons and rods because the twin turbo kit will more than max out your motor if you up the boost. and then take the rest and have the heads ported with a set of cams and a ported intake manifold or custom sheet metal intake made. if you decide to stick with your plans of doing compound boost i would plan on getting atleast a 3.4 whipple or bigger because down low you will start the blower due to the turbos not spooling up restricting it and then in the high rpms the blower will restrict the boost from the turbos with anything smaller than a 3.4. i have looked into this before i twin turboed my car and compound boost is not worth it

He's not a troll. Come on, you guys, he just wants to know what effect a whipple supercharger and twin turbos have on gasoline tank capacity.

I know I lost 1.5 gallons capacity after installing my caster/camber plates and my LCAs knocked off another .5. When you take into account the .8 gallon gain the Mach 1 Shaker adds, I'm currently at 14.5 gallons.

If those twin turbos feed into the fuel tank, he's gonna lose a good three gallons.
