Price is certainly a lot better than what 2nd hand trashed Group A ones are pulling.
The standard throttle bodies would flow more than enough for 99.95% of street engines, without having to "upgrade" to the more expensive option - and you probably wouldn't be running this manifold if your motor needed that sort of flow.

The only negative I can see with it, is the runners are very short, which reduces torque at low & mid RPM torque.
The Holden TTBs have trumpet extensions coming up further into the plenum, giving a longer effective length - thus increasing the low to midrange torque output.

Was looking at doing some thing different, It is just only a standard motor at the moment.
