Re: the DV Live Now post
What's kind of interesting in this latest EMC and EMC rebuttal is that if I understand it correctly, the 128 "formula" came about from innumerable dyno tests. That is, for a "given combination", (and we've seen that combination is very specific in the grand scheme of things), gr...

Re: the DV Live Now post
No disrespect here, but rather than telling us how good you are i would have thought the best way to prove something was with a comprehensive set of undisputable test data that supports your position. Just how manytimes do I have to show my worth??????? You know I might just have other things to re...

Re: That 128 controversy
David, In the video you talk about the opening and closing rate as being important, I agree. But is it not easier to just say what happens in effect is the overlap specific time area increases and easier to give a number to, rather than increased valve acceleration? After all, keeping the opening a...

That 128 controversy
First a quick note to Mike here. I wish to address the entire ST community not just the ones who read my section so here goes. How many of you have looked at my 128 LCA proof of concept video on my Powertec 10 YouTube channel. Let see what arguments the nathsayers can bring to bare after watching th...

Re: David Vizard's 128 cam selection for small block Chevys
Waste of time. Title "Hyper advanced ProStock-plus, cam tech" for a video about 10:1 SBCs targeted toward complete novices with nothing at all relevant to Pro-Stock. Jon, Only you could misinterpret a video that is about as explicate as it gets. It will predict a ProStock cam right on the...

Re: Big shout out to David Vizard and Terry Walters of TWPS
What did you pay to get the DV specs? lol. Not laughing at you, just the idea of his arrogance. Also, doesn't surprise me with the ethics, it's happened before . Also, whatever you were told it would make, subtract 10%. Not a fan. Big Chief, do you even know DV? Have you ever had any dealings with ...

Re: David Vizard & Terry Walters Sad Issues
Hi, It is with great disappointment I've head trying to solve issues with both these men. I've purchased a engine built by Terry Walters to David Vizard's specifications. I've only had issues paying for things and not receiving them. I've contacted both these people and got the brush off from them ...

Re: High efficiency small engine
I'm looking for a good small engine to use to power a 300 lb car (with driver) to get the highest fuel economy possible. Would a two stroke or 4four stroke have the advantage here? I am thinking maybe a moped engine or maybe something like a new 4 stroke MX bike engine. Any suggestions? Jon, Before...

Re: D V Live now.
More fresh DV on lobe sep angle https://youtu.be/IjfwqgpspnA That's a weird video, it's mostly about overlap and he keeps brining up LSA, then it's about intake closing in relation to compression and he fails to mention that and calls it LSA. Old mate obviously didn't need a low idle speed so he go...

Re: the DV Live Now post
David, none of what you posted validates your 128 gimmick. The fact that the following variables influence the ideal LSA, and that your 128 formula does not take them as input, is all one needs to know to understand that the 128 formula is not comprehensive. Throttle size Intake manifold Port flow ...
