Reply With Quoteno.... but that makes perfect sense wops ha ha
that measurement is just from the top
Did you measure both the 'long' and 'short' sides and average them, due to the angle of the manifold adapter?

I figured as much, lol.
If you still have the manifold off, take a piece of wire and form it along the top of the intake port to the valve, and another along the bottom of the port to the valve and average those for port length. Mark or cut them, then straighten and measure.

good idea
but im not really doing any more further development on this so not really bothered
would love to stick one of these motors on an engine dyno and get really fidley with it changing inlet and exhaust around to see the different effects

"my mind demands side pipes out of hear, now to command my hands to make them"
all i do is open the throttles and put a tradys plastic ruler down the port with the cyl that has the inlet valve closed and measurefrom back of valve till it hits the bellmouth ,this should be close
im at 385 mm at the moment and power drops off at 9k with this length
new special ram tubes are now ready will take a pic this afternoon and put up
INTERESTED!!!!
when will you get a chance to dyno it??

1 broke when i was setting these up ,so it wont be for a while ,but i am dyno tuning a new motor new week end with the same length so see if i can get a idea
also have changed diff ratio and gone up to bigger tyres 225 on the back now and also 4,55 ratio. so it was 205 and also 4.3 originally
bumping this up
so say i have a 16v bigport and if i had an ITB adopter plate that was longer in length then the T3 adopter, but this longer adopter had a bend design to them, will this effect air flow/overall performance?
i got my eyes on a set of different adopter that's for sale and never seen this kind of design before..will this act the same as having longer stacks?
will it act like having stock 20v stacks as they also have a bend from factory?
or am i just better off with a more straight setup like most typical ITB setup?
here are pictures of the adopter in question

dose
also interested in this.
this is the 16v head cross sectioned.
as you can see the port come in at 90 degrees then turn down rather harshley.
how would angleing up the inlet manifold affect flow into the chamber? i know there wouldn't be much in it.
