That is some crazy big ports.

A close up would be nice.

I'm not even going to ask if they support the sideseals

Did You bevel ?

 

hey im not sure aye i didnt do the porting, the engine they were in ran so im guessing that they made sure the side seals were supported,



heres a bit of a close up

i was just lookin at doing a port similar to this on an n/a engine



it supossibly made 160kw at the wheels

 

With no better picture, I am guessing that the bridge is far to thin and will crack after short use. The longer the bridge the thicker it needs to be.

cheers for that bit of advice lynn

 

ive got another question which one of you more experianced people might know ,



now increasing the port size out to the side eg bridge/j-port increases you inlet and exhaust over lap/port opening time right. but what if say you had a bp and you moved it up more towards the top of you plate or to the bottom

what i want to know is how would ech one of these ports effect the engines characteristics



would it **** the power band up down etc



any insite would be much appriciated,

 

That looks like a 6 port endplate hogged out to one big super bridgeport. i can't see any good velocity or proper flow happening here.
