Roush chicane fuel pump& KB boost pump

saleen556 · Oct 5, 2005

Has anyone used the boost pump with the 255lph pump?I just had the KB 1.7 installed and the boost pump is make it run real rich.I know KB sent me the boost pump for the cobra because of the larger than stock pump.I am thinking if I just swap in the cobra tank and pump it will solve the issue.Any thoughts?

I'm running Joe's 255 lph pump and a BAP. The BAP is turned all the way down. Do you have your BAP on all the time or set up for increase in voltage/vacumn?
I have had no fuel issues as yet with this set up but the absolute best thing you can do is go Cobra tank and pumps. That is the best combo yet short of going completely custom.

I believe he has it set up to increase voltage under boost.I am waiting to find out what he came up with yesterday.He was not positive that it was the pump that was the problem.I just picked up a 2 month old cobra tank and pump from a ford mech last night to put in if needed.

Just look at your BAP and if the vacum line is not connected then it's probably constant and you can adjust form the knob.
If you have the 03 Cobra tank and the pumps dont even bother thinking about anything else and install.

I just took the pumps and tank in and he installing them this afternoon.He will try to get it tuned this evening.The KB looks really good under the hood.He was able to swap some fittings and keep my heat exchanger,resevoir and intercooler pump.It looks nice and clean and saved some $$ on the labor.I can't wait to get it back.
