Anyone know what a Cozmo 20b fuel pump flows? And what kind of horsepower it can support? I've searched but come up short.
Thx in advance for the info...

 

310l from what I remember. People seem to run it around 600hp no problems.

 

I would be extremely surprised if that is correct. The Supra pump outflows the cosmo and would be hard pressed to hit that kind of hp number using a reasonable AFR.

 

Anyone have any first hand experience with it..... I'm asking I'm running it right now because of the previous owner and I'm shooting for 400 or higher in the spring. I need to know if it will flow enough. Thx for the input so far guys.

 

Go to Max Cooper's site (www.maxcooper.com) and use the fuel calculator to determine how much volume you need to move at X pressure. Then use the fuel pump data listed at http://www.stealth316.com/2-fuelpumpguide.htm to determine if the pump is sufficient.

 

1 won't flow the 600 hp mark. On the two three rotor cars I have worked on we used 2 pumps using a dual fuel pump bracket, and paralleled the fuel lines in the tank.

 

wow there is so much misconception surrounding this pump.... hard to decifer the real flow ratings..

 

I have seen a couple of people use two Bosch hi-flow pumps for this application. They seem to work well, but cost a pretty penny.

 

If you do what I suggested above you will get the info you're looking for.

 

The website that CCarlisi posted has alot of useful info on it. It shows the flow rates at different voltages on several fuel pumps.

Alright i did what u told me. The numbers that i need according to the calculations page is a pump that will flow 206L/hr at 74 psi........ The 20b pump supposedly will flow 250L/hr at 43psi and 12V. But according to the flow charts at 74psi it will only flow close to 180L/hr. So i guess i need more flow? or a voltage boost?
