My Head porting development

[Turbo4L]

Hey guys we just cracked 217cfm on the exhaust side with 2mm os valves and a 95mm bore and 304.5cfm on the intake with 2mm os and 95mm bore.

I think these are the highest flowing figures for these valve sizes.

Will post up pics once the new 3.5mm os heads are ported.

Cheers

Holy flowbench, batman! Let's see the graphs and some pics of the heads.

Will do. but first I want to get the 3.5mm os heads done.
Once this is done it will be onto the head flanges then full plenum.

Just cracked 317 on the intake with 37mm intake valves.
Digitizing this port job before we go any further.

Cheers
