I am currently running a single A1000 pump.
Its rated at 1000 fwhp forced induction.

I am going to turn up the boost so looking to upgrade to a bigger pump or run dual A1000...

Any suggestions?

I was looking at the Aeromotive Eliminator rated at 1400 fwhp f/i.

 

-10an absolute minimum on Eliminator. I know of at least 4 guys running the eliminator on boosted street driven Mustangs with no reliability issues

 

I think your ok with the single a1000

 

I have dual #8 into a Y then to single # 10...
I plan to change it to dual #8 into Y then to single #12

 

Why do you say that?

 

Get something soon so u can tune and be ready. We have a grudge match with Mic.
