How Much Power Can a 1600 Dual Port Make? We’re Finding Out!

[/quote]You're disregarding one of the most knowledgable people here(whom I've learned a ton from over the years) and then you cant even type his name correctly? You should be trying to learn from him. Not getting butthurt because he's pointing out what you've done wrong(and more importantly how you can improve). Goodness gracious you need to learn humility. Did you expect everyone here to just kiss your ass because you've made these video's?

You're not doing[/quote]

Thanks for watching tobi! We appreciate your support!

I have never been called a troll or a narcisist before. But I guess there is a first time for everything

Guys. It took me a while, but it suddenly dawned on me. Most of us, myself included, have been looking at this the wrong way. It actually SAYS in the header "Fun"
I for one took it as educational There is not much educational about it apart from what random parts have been thrown at those engines, results in this behavior.
Apart from that my comments still stand.
And no, BFB I am not embarrased at all except for the fact that it took me so long to realize the intention of these vids. But, maybe you were one of the few who got it right from the beginning. If so, good for you.

Formula Vee, Secrets of the Ancients (revisited)

I made what is turning out to be my bi- annual visit to my Formula Vee buddy. It's turning out to be a nice little cargo cult. I bring old 40 horse parts and swingaxle transmission cores. He trades hi- po parts that aren't SCCA legal.

I'm incredulous but he claims 75hp and a motor that will rev to 7500rpm using largely stock 40 horse parts. I keep tryin' to figure out how he does that must be a trick cam and high compression at least from a brutal flycut. Nope. Rule book says stock cam, 7.0:1 compression.

Most obvious hi- po part is that mid- '60s Indycar wannabe exhaust.

I want to turn this guy loose on an old school high compression desert motor. The formula there is 1600cc (rule book sez 1600 not 1588), single port heads, any cam, any compression ratio, 30PICT1 carb, race gas is legal.

Newer "low compression" formula is 1600cc, "stock" dual port heads, compression is limited to 8.0:1, any cam, single "40mm" two barrel carb w/26mm venturis, stock unported dual port end castings, 91 octane pump gas.

We can throw spaghetti at the wall in this case a 1600 dual port and the spaghetti being random modifications... or wouldn't it be fun to develop a combination that makes real power.

I have been thoroughly enjoying the videos. I did have to edit my expectations as I assumed this would be a "scientific" step by step walk through the typical upgrade paths culminating in a successful..."here is the way" type finale. This seems to be far less rigid as I expected, but fun and interesting to those of us with a LOT less experience and understanding of the finite details of engine building and tuning.

That said, I appreciate Alstrup and the others who have chimed in to help give experience and background and hard learned lessons. I know some of these guys have more DYNO hours logged than I have seat hours in my car!

The only discouraging thing about this thread is the inference that one party or the other is "ruining" the site or the internet or the community. The whole idea of the community is to have MANY voices. Its the MANY voices and discussions that lead to the most beneficial discussions and the most learning to me. I learned a lot about Ignition in this thread that I was not directly searching for...to be honest, I didn't know enough to know that I didn't know things! LOL

Y'all keep making videos! They Rock. Y'all keep replying and dissecting. Its interesting and educational. This whole thing is working as community is intended to work!

Yes the danger is that one party thinks they "know all" when in fact no one "knows all" then the newbies get led down the garden path. Been there, done that but in my day it was the popular VW magazines that I realized much later were not there to help anyone apart from selling their publications and selling parts for their advertisers. It was byer beware!

The same holds true today, it's just that the internet has taken the place of the publications, the turnaround time is measured in minutes instead of several weeks and there is now feedback from the audience. This feedback is not always better than the original but with careful consideration, common sense and a knowelage of the basic laws of physics the kernels can be sorted from the chaff.

I guess my disappointment is that it appeared to me that these fellows were taking the "Something for the everyday guy driving in the real world" approach and I believe in the beginning they were but now it seems to be another of so many other "Reach for the top end" videos. Yes they are still limiting it to 1600cc's but that is all that's left of the original intent.

Perhaps though I was looking for something that was unrealistic. I will continue watching their videos but it will be more for the entertaining banter now rather then the content. But that's just me...

I think the series is very helpful for newbies. The typical newish owner decides they'd like a bit more from the engine, but don't want to rebuild it so they look to bolt on "improvements". Exhaust, carbs, fancy distributer. These things aren't cheap but get bolted on because it's easy and they don't need to tackle the actual engine.

This series is very good for finding out that this approach just burns money with no noticeable improvements. With the knowledge that the only way to make noticeable gains is to build the engine bigger/different, they can save a lot of disappointment.

Granted the improved engine likely wants the bolt on goodies too, but it's so much better to do the engine to begin with.

Anyone asks me, for decades I've advised making the engine itself better as the first step. The bolt on goodies isn't wasted money once you sort the engine, but doing it it the wrong order wastes a lot of time and causes disappointment when it doesn't have noticeable results.

In this episode we get the engine finished and find out if our build plan works!
After this one there's only two more episodes of this series. We take it to the dragstrip in Seward Speed Shop's drag car, then the series ender where we do a complete recap.
We still have to get the engine in a car though. That's going to be series two, coming up right after this one. The car we chose for it is a barn find 1967 Beetle. It's going to become "The Green Sleeper". Stay tuned for that!

Cool, I’ll be watching it shortly.
On your boost control. I’m using a factory waste gate, also. After clocking my turbo to fit my application, I was very concerned with the adjustment on the arm length. The last thing I wanted was a constant boost leak. I just think adjusting the rod length to control boost is not the way to do it. My thought is, it would just adjust how far the gate opens. I have one of those boost control bleed valves for the vacuum/boost hose.

Had to catch up and watch the build and then the first run videos. Always entertaining! Be interesting to see if this motor built for a turbo is reliable over time.

FunwithVDubs, did you guys do anything special with the heads? Good valve job, fluff&buff or mild pocket port? Or are they straight out of the box? 37x32 valve sizes?
