- Dave shows you how he goes about porting a OEM Corvette C8 plastic intake manifold. This is going on a head and cam car for our friends at East Coast Supercharging!

I designed OEM intake manifolds for 7 years. It’s always interesting to see how people modify them.
When we tested the manifolds to failure, they would usually burst near the weld flanges. I’d guess that thinning the walls near the runners or TB flange would have little or no impact on the life of the manifold.
Sorry for the steps on the runners. They were usually unavoidable due to cheap manufacturing processes.
The attention to detail on your port work is impeccable. Thank you for showing your porting secrets to us Corvette guys.
Thank you for the kind words!
Thinking about doing this myself for my C8.
The video was short, I love watching you work Dave.
A greeting from Spain
I just ported the extra one I got off eBay. Mine doesn't look as good as yours. But, I think I will be okay.
Have you ever ran some abrasive putty through a plastic manifold before?
no, I would never do that. Unless you have a way of telling the putty what to remove and how to shape it.
Would of hit like button but didn't show before and after HP...
@@tilligetbig sorry to disappoint, it was apart of a build
Aww man not a dynocom dyno. Haha. Love from NZ as always. Damn that intake job was nice.
I like this videos man keep them coming ,by any chance did you record the VR30 head getting ported ? I’ll like to see that
There is a pinch just past that first seam, as you go deeper into the runner is there much material on the sides? The lower part of the intake runner near the head has something to work with(sides), not sure past that first seam toward the plenum
I am not sure, I feel like I showed that on the vid.
@@headgames Im at 1.57 at the port opening, just not sure I can go 1.57 past the pinch ....... I think that transitions to a much thinner runner wall
How do you measure wall thickness? Same way as with cast aluminum?
What were the power gains?
I’m not familiar with a way to do it . But also not trying to make it as big as possible
do you port subaru plastic manifolds?
Sounds like he’s would have 2 customers so far. ✋🏾
Never seen one. I think there’s better options
What was before and after?
