Budget racer surge tank

Recommended Posts

Commencing surge tank research.


After some simple insurance for the banger race car. I have a walbro intank and want to add a surge that I can use in hillclimbs etc (cams compliant). Nothing fancy just cheap insurance.


Any advice of what works is appreciated.

Ebay surge tank, Bosch 044 external pump and filter if not running E85.

6mm perspex box if sitting in boot.


If running E85 It's a bit trickier to get the right surge tank.

Pump wise you can run an 044 but they are only rated for 500 hours. Which is a fair bit of time in the car realistically.

Proflow do an 044 knockoff that is apparently E85 compatible.

I'd probably look at something like a deatschwerks or walbro inlines over the proflow though.


Just cost it all up beforehand with fittings etc. You might find you arent all that far off a taarks surge tank with in tank walbros.

I am at the same position as you but can't decide which way to go !
