Trumpets or not?

[Mongoose]

I see on e-bay,that it looks like Rob(v8 racing),is selling some tasty induction mods,that come off a Taraka engine.The trumpet base has been radiusd instead of using flared trumpets.I wondered what the difference was in performance terms?Mine has 45mm trumpets,so i was just curious

I've yet to try back to back on a big hp 5litre though so all my findings are 4 litre based only so far...

We could do something about that
