Re: Dual HIF4 Carbs

Daniel - thanks for reply.

I am familiar with Vizard's book and airflow numbers with SUs and Webers. 
However, Vizard's comparisons are for HIF6 (1.75") against other SUs, 
including HS4 (1.5") BUT nothing for HIF4 (1.5"). That's why I am wondering 
about use of dual HIFs.

Oh, plus the fact that I already have a pair of rebuilt HIF4s.

Has anyone other than David Vizard done similar airflow tests with SUs?
