Re: Cag port timing
So if my working out is correct
Exhaust duration is 160
Transfer duration is 110
Boost port duration is 120
I have got .65 squish so I'll matching .15 off top of the cylinder to get the .5 squish
0.5mm is roughly 20 thousandths of an inch..That would be a compression ratio of about 17:1.Better get a welding glove to pullstart it if you go that route
At .050" squish youll get about 140-150psi......I run my squish mainly at .030"...Ive run them as tight as .024" and got piston to dome interference and had to modify the pistontop on a mini lathe to true the top up..
