Yes its me again,just want to ASK if the following pp dimensions is right .Will this porting work or not.
exh port is 25mm by46mm big standard
exh port modded is3mm down and 10mm up,width stay the same at 46mm(so modded port is 38mm by 46mm big)
Now
from top of exh(modded one) go up 76mm.Inlet port starts.
Inlet port is a d- shape(upwards).port size is 55mm by 55mm big


(1) how big IDA?
(2)How do you mod the rotor sides(clearances?)
(3)how big exh manifold?
(4)is a 76mm free flo exh big enough or must it go bigger?


ANYONE Please!

(person from who i got dimensions ,cliams 170-180 kw?.True or false!)

 

come on guys,is there no one out there with info?Dont worry about the fla.... club or are they on strike?pm me with any info please!

 

show us pics so we have something to tell u

 

We go by port timing, not port dimensions.

 

i think wider is better for the exhaust port but not too wide cuz of the water jackets u will make it weak

 

peejay
only got dimensions of exh,intake no port timing!

say you must put sleave in intake port so it will not become weak,but intake will be 55mm by 55mm after you finished it off etc.
dont know????
