That jet flow pattern takes up space which is why i think it wouldnt be so well suited to an undervalved big block. Turning the flow in suspension is a another problem, Some visual; https://youtu.be/9ynUQls8_gc?feature=shared Screenshot_2023-09-29-11-22-24-67_92460851df6f172a4592fca41cc2d2e6.jpg -ju...

Im not going to mess with the folkrace vw with lava, but spare Mummert this too, as my colleague wants me to look at his Ariel red hunter 350 at some point. [-o< A undersquare hemi-chamber vintage engine that needs to maintain a standard appearance (and only one cam lobe for both intake and exhaust)...

I think Mummert said it well (other factors) and i want to thank that we get to read about these works. Reading about Mummert's experiences years ago made me try to see if i could change the flow in the air cooled vw. I thought that the point where the flow changes (significantly enough) was possibl...

Thanks Stan,

Well for me who only recently started to keep track these things, 3.225 inches sounds like a distance i wouldnt have the patience to test the difference.

Let say we are tuning a engine to peak power and planning to open the intake at 32, closing it 74 and using a symmetrical profile so that it lifts highest somewhere 112 degrees after TDC / past max piston velocity and with the flow going in one direction. How far down the hole would the piston be at...

Is that water with food coloring? Instead of making all the mess with the machinists dye and all that nasty vapor in the air, why wouldn't you use water for visualizing while doing the initial setup of however the fluid is being introduced, nozzle(s) or ? I dont know if the food coloring would add ...

Please excuse me, but what is this a picture of and could you post a link to the interesting reading?

Good questions. I was just finding a way to see rough velocity gradients past the valve and across the chamber so didnt have high expectations for the test, but seeing the water swirling in from the plug side before modifications.. I was impressed and thought maybe i got some fix for a problem by ha...

I found some interesting reading about air cooled vw, then i remembered this thread and finally got something done! I mean the VW guys have an unfair advantage in testing :D If we let the gravity work for us, then there is fluid flow from high pressure to low pressure right? Not to mention how much ...
