Here`s some pics of the manifold, as u can see there`s quite a bit of tig welding,grinding and polishing left to do on it..

It`s going on a bridge ported 13b 6port.

Any thoughts?

Looks excellent so far!!! https://www.nopistons.com/forums/pub...IR#>/smile.png

Looks good. You need a plennum though. That is unless its a WOT type of setup. If there is a reason for not having one I am very curious as to why you went without one.



What formulas did you use for your runner length and id?



I have been wanting to do this for quite some time. I cant wait to get my TIG.



Keep us posted

why the stock tb?

stock tb is big, those plenums look slightly long?

dont forget to add injector bossses https://www.nopistons.com/forums/pub...IR#>/smile.png

stock tb usage forces you to have quite a few bends... I prefer straight intakes right to the ports.

It's a BP, thats why the runners look long, It looks nice, looks like you were trying to use dynamic intake effect on it yes?





this guy's aircraft manifold uses vdi too
