Volvo 1800ES: Barnfind to B230 swap

Hey! Nice work! Love those cylinder head improvement videos! Nice to learn something new and also maybe one day go ahead and port my 16v head for a bit more beneficial and free flowing design!

Keep it up!

Thanks man. I’ve got a bunch of video content I took on these heads . I go into the idea behind this port shape and all that, but I just haven’t had the time or effort to edit them together into a proper YouTube .

I’ve been super lazy and just make quick un-edited IG vids because it’s easy .

I really should put time time into editing these together .

A 16V would be great. That’s such a great flowing head, I’m not sure porting would gain much. With a 16v, really the most important thing is a good cam, and good intake .
 
Thanks!

Well, i have seen some plans that someone has showed me for a 16v head porting that i need to find so i can share with you. There's so much to gain from the head it's unbelievable!!

Even taking 1mm off of the valve seats gives you really big gains in flow.

I'll see if i can find it all

Cheers, Adam

Just be careful opening it up too much.

An engine will only flow what it can flow, putting a 300 CFM port on a 2 liter engine is guaranteed to reduce power . For example, trimming the short side on an LS does increase flow bench numbers , but it reduces power because flow velocity and swirl drop.

Flow velocity and correct intake tuning are what drive flow.

If you can make a silicone casting of the 16V head and mail it to me, I can make a scan and play around with some analysis, let you know what I think .

I’m super busy now, but I’d really like to get back to writing an engine dynamics simulator. One that models transients and pressure waves in the intake . Regular CFD only models steady state flow, like in a flow bench .
 
That is very interesting. I could try making a mold for you, but it will take time, as i live outside of US, plus i have no workshop to use at the moment as i lost my garage and all the car stuff is now locked away in the container in the village where i used to live in the UK.

Cheers, i'll keep it in mind, tho.
