Performance vs Cost

[DrZed]

Supposed to be. But the bio and the posts don't match up on gravitas.
Plus way too much hand waving and so far, no useful or new insights.

Hoping for better to come.

Roger that. Thx.

Understand. But a ballpark figure would be helpful. As would an expose in which sub items of the expenditure were most useful.

I did this project almost 20 years ago and a lot of water has passed under the bridge!

Ok. But you'll be doing very similar work on the 700hp build, yes?

Please post 1 single new idea that you have researched, developed, A/B tested, and that moves this platform forward and you'll surely be welcomed with the fan fair you most certainly feel you deserve.

So far all you've done is promote a YouTube channel and regurgitate how amazing it is that the bolt on improvements people have been doing for decades actually work... but somehow when you do its original and we should all applaud that you're "working your butt off". Its sad, give it up, move on.

Your comment lease post 1 single new idea that you have researched, developed, A/B tested, and that moves this platform forward and you'll surely be welcomed with the fan fair you most certainly feel you deserve.

My answer:- My last Ecoboost video () detailed the results of our 2023 dragstrip testing and resulted in delivering the effectiveness of at least 5 back to back tests as well as a never seen before product test which worked probably better than any such product that came before it.

But having given you an example that contradicts your comment I see no further point of me putting forth my side of the debate here.

It's you making the outlandish claims but you have very obviously failed with a 'due diligence' research effort on the subject. That said it's up to you to make me out as wrong. Best of luck with that. Episode 85 of PowerTec 10 () will prove you massively wrong and that is just one of literally hundreds of examples.
Do the job properly and I think you will find an apology is well within order though I am not holding my breath on that.

That's all been covered repeatedly. Here, and on other YouTube channels. Don't try and hang your hat on your specific combination of modifications, that doesn't matter. Tons of people modify and test their cars, and then share the information. But that's a whole world you seem to be oblivious to.

The word 'all' is totally misplaced - there is at least ONE piece of info that has never previously seen the light of day and a good few points that are rarely discussed. But at the end of the day this is what Andy and I did for 2023 so it is totally new, and previously unpublished material!

If your comment here is referring to my episode 85 then you either don't understand it or are being deliberately misleading. If the misleading is deliberate then there is another word for such and it starts with an 'L'

That video was what we found and did in our 2023 season of A-B drag strip testing.You know that's the stuff you seem to think I never do!


Tons of people modify and test their cars, and then share the information.

What a load of ******** that is. So it's OK for tons of others to modify, test and share the info but for some reason when I do it I get blasted from just a few folks who think for some totally unexplainable reason it is a mortal sin for me to do it. Would you care to be more explicit on your statement here?
And BTW tell me, who on the face of this planet, do you think might have shared more performance auto tech info than me!
I bet, as is the norm, I don't get a straight answer on that one!!!!!!!!!

My counter to this comment:- - But that's a whole world you seem to be oblivious to.

There is an old saying - people in glass houses should not throw stones. Check your fact finding as up to this point you seem totally oblivious to such things as facts.

I just watched your header video. My teacher for headers was Ed Henneman (sp)

Everything he was saying in the 60's about tube size I see you agree with.

So now if I take my Ed designed headers that fit my big block Nova and add 4 inches to the primary of 1, 4 and 6 along with subtracting 4 inches from cylinders 2, 3 and 5 I will make more power? What about cylinder 7?

In your video you used a 572 but did not give final power numbers, unless this was the same engine referenced earlier in the vid.

I hate videos because they always move too slow and I switch my attention elsewhere.

So Vizard, this is just moving the pulse timing this way or that to better combine pulses or otherwise improve scavenging. It's textbook stuff though.

Does this have an application to the headers for the 2.3 EcoBoost in the mustang?

Have you arrived at a superior routing/sizing to materially fix a set of tradeoffs the Ford team made?

your comment:- It's textbook stuff though.
My response:- show me. Knowing where I could have found it would have saved my a good few thousand bucks!

Since at least the 80s when computational fluid dynamics really started to get affordable? These days they just model the wave forms and propagation using computers. Doing it by slide rule takes too long.

I had a discussion with a guy back 30 + years ago discussing the finer points of I4 pulse timing and why he had elected to have a shrouded exhaust port and then a chamber right after followed by more traditional diameter for his Honda 750cc. And he didn't have to rent the university supercomputer to figure it out. FMF has been making "bomb" headers for how long?

Sure back in the 30s thru perhaps 60 this wasn't taught. Hell, it took how long before the 2 smoke guys started to figure out how to use chamber shape to lend a hand? Mid70s?

 

[K4fxd]

I still would like a clarification.Where does cylinder 7 fit? You are using cylinder 1 twice. I doubt 7 and 8 would be nominal.

Next question do you know why these cylinders need differing lengths? Is it because the intake manifold has differing length runners?

All I know is Ed was/is (Not sure if he is still with us,) a pretty smart guy who has been proven correct over the years.

Mr. Shogun32
My apologies here. I was under the impression that we were discussing the unequal length deal not exhausts in general. Just to clarify I have never seen anything on unequal length headers before.

You still won't answer my question.
