Agree w/ Eric. In a 2500 lb. car, you won't sacrifice streetability by running the single-plane. And it is also true that not every SP produces more power than a DP. It matters what other components are mixed, matched to equal the total picture.

I was told I had to run a dual-plane in my Tunnelport because of streetability issues. I have the single-plane, and would not trade it for anything.

You should really look at where you want your power to be and then see what the dyno says.

In general, DPs are maybe an inch, inch and one-half lower than SPs.
