very well actually. To be honest, with a forced induction, low tech 8v headed engine, a lot of the theory is cobblers in practice imho. That manifold with decent mapping (that car also ran emerald ecu mapped by the legendary Dave Walker
) ran really well
it was a laggy setup, but then the Pulsar T3 is known to be laggy when fitted to DETs or SRs as well.
but being a tart i went tubular which was a lot more hassle
but did work well in the end. For up to 250hp i think the runners were too big on mine, should have been 1/4" smaller diameter for improved spool
