I worked with Gerhard @ Bell to design mine as well. Mine is based on a 4.5" full bay core, but different than David's though (There's a picture of mine in the Turbocharging Performance Handbook ) - Gerhard suggested a left-right core as opposed to front-back.

I am very happy with the performance though weight is the big penalty. I remember weighing mine & its close to 40lb.

I suspect if you only use your car for street, a thinner core would suffice.
