Surge tank in boot?
Surge tank in boot?
Has anyone put a surge tank into the boot of a Starion? I'm keen to see pics etc of what you've done. (ie. where it's mounted, where the lines go etc. Also, has anyone got one engineered?
I have put one in. It is mounted inside the rear hatch on the left hand side right behind the inside wheel arch. The fuel lines run though the holes in the left hand corner of the boot. I have an in tank pre-pump, with the fuel pump being mounted to the fuel tank join on the LHS inside the lower part of the rear 1/4. This leads to a Malpassi fuel pressure regulator. I don't have pics but I will take some next time I have access to a digital camera.
Now, as far as I understand, this set up is not legal as all fuel system components must be seperate from the cabin. This may be possible if the surge tank and lines are sealed when placed in the boot. You would have to speak to a certified Qld engineer about this for clarification of any laws in Qld.
Another alternative would be to place it on the inside of the LHS rear quarter and then seal the pocket with a panel. The metal boot cover will also have to be sealed or remade as a sealed unit. My surge tank is too big to fit in there so I will more than likely do the third method.
The third method would be what most od the RX7 guys do. My old rx7 13BT had the surge tank mounted under the car in front of the fuel tank along with the fuel pump. On the Starion, you could easily do this shortening the fuel lines to the front of the tank and mounting asurge tank and external pump there. I haven'tbeen under the back of my car for a while so I am unsure of exactly how much room is there.
Having said all this, I still think that a sufficiently flowing Bosch pump can be mounted externally without the need for a surge tank. Something like a 910 pump will flow plenty and can be bought for under $200.

Yeah, as far as I know, any fuel lines, tanks etc must be sealed off from the cabin (I think you can put them into a box legally). It's a bit of a problem with the Starion being a hatch.. can't really seal the whole boot area off. The tank I have is pretty tall so I doubt there's any chance of fitting it under the car.
What are you using for a lift pump? I was thinking, at least initally to just use the stock pump to fill the surge tank and then route fuel back from the engine into the surge. Problem here is that the fuel will probably get too hot, but at least the Starion pump will be able to keep up with the big efi pump.

I use a pre-pump (VL Commo I think) to feed the surge tank. Cost is about $80.
If you placed the surge tank on the inside of the rear quarter and made a sealer cover for it, then you could then mount a bigger pump in the factory location with a lift pump in the tank. This would still be legal as the only mod (the surge tank) is sealed off inside the rear quarter in the hatch pocket. Best to check with an engineer though.
You could just use either an external or an intank Bosch pump without the surge tank and lift pump. If I was doing things over again, I wouldn't use a surge tank on a street car. There are even track cars that just use one pump without a surge tank.

if yau are going to plumb the injector return back to the surge tank, make the tank at least 2ltrs, other wise the fuel gets hot.
