Richard Holdener had a video of a modded TPI intake. I think that it had a extrude honed lower, larger throttle body with the air foil. Can't remember what runners He used. It made good power!
Might be interesting to get Cletus' old pal from Tampa on . The guy with all the golden retrievers . He and or his Dad gave Linkenfelter fits back in the day when this stuff was new . I'll remember his name right after I shutt down ... on edit : his channel is Fastproms . His Dad was very early in modifying stock ECU's when you could not buy stand alone tuners .
the aftermarket bases are a different animal they will be what your ported base is if not bigger and straighter there are two castings the edelbrock 3860 and the ACCEL/Lingenfilter, the edelbrock is bigger flows more and has more material than the ACCEL
Ok so I caught onto something you mentioned…harmonic 🤔. I realize everything has frequencies (vibration), and I’ve heard you talk about noise in the process of some of these modifications-Reynolds number I think you called it; but when you said certain designs of intake were created with a specific harmonic in mind…I had a hard time wrapping my head around that.
Difficult task to make these better. Add in the 180° Turn the upper manifold makes. I rarely seen these used with being extrude honed. I would like to see the comparison between this and the Ford 5.0 intakes. Both used during the same production years. Wasn't the edlebrock pro flow the largest by volume version of these? And the equivalent ford trick flow. What was the Callaway corvette equipped with during this Era? It used twin turbo, but what intake system?
The Callaway used a regular tpi but it was painted or powder coated black. The sledgehammer used a heavily modified tpi where the sides of the plenum were blocked and "runners" ran out the bottom straight into the base like a stealth ram.
Hi Charles! You were mentioning here that the air wants to go to the short side, when it needs to curve. If this is the case, then wouldn't it be justified to grind down the short side of the intake port, as well as it so often tends to curve just before reaching the valve? As a suggestion, you could try to fill in the 1-B area to even out flow there..
No input, I've always removed the tuned port system. I do know there is, or was a company that made LT1/LT4 conversation manifolds to replace the tuned port. TPIS maybe?
I noticed that the outside edge corner speeds were dramatically lower. Wouldnt that indicate either widening the central straight or filling in the outer sides of the turns to even out the speed differentials at the corners?
Very interesting Charlie. Sometimes you have no real option other than to increase the csa. Hopefully, each point will line up with an harmonic point, but you couldn't be that lucky.
Not only is it first harmonic, it's tuned to 4500 rpm peak hp. Now I understand why 340 hp was really good for a TPI. I'm curious how much torque you'll see.
Alot of information Charlie. I dont think anyone has done it. I was wondering how the helmholtz effect works on different intakes. GM did a enormous amount of work on the C8 Corvette and it produced a supercharging effect. NO supercharger.
There was a guy in a forum somewhere that was looking into a higher pressure wave tuning. 3rd wave tuning, I think he called it. He was seeing like a second power peak at like 6,500 on tpi systems and was working to exploit that phenomenon, but I don't know that he ever proved his concept.
@@andysteele4056 we have to remember the effects of every factor in the equation. I think I understand now, it’s what accounts for the anomalies we’ve all witnessed where some guy’s unimpressive combination of parts runs like a beast! The combination of parts that works together in concert outperforms a differing combination where one of the components drastically outflows the others…even if the odd combination has(higher total flow than the matched set. What’s the optimal length of collector pipe to draw a breeze(supersonic pulse) through the front door? How perfectly symmetrical are the other (runners/chambers/tubes) cylinders to the test bed-where the overlapping cylinders essentially create a drafting effect? A perfect combination can create a phenomenon. Way back in the day.. Mopar used a design with super long intake runners called the crossram. That’s what that design was made for-to create a supersonic pulse, and it made boatloads of power for that time.
Just heard that Berzinske sold out to a former employee. I messaged them about your 193 TBI heads and told them how awesome they are. They are sill going to do all the cast iron stuff. CNC program?
Excellent. I averaged everything and it looks like point 1. 264fps 2. 328.5fps 3. 309.75 4. 320fps - average port velocity = 320fps! That actually aint bad. I agree the runners should be more even and maybe we can figure out something. I know I am handing you the real Mission Impossible.

We will find out. Thanks

I have to get more into that myself. Thanks

I have videos on 5.0l Mustang intakes. They max out about 160 cfm! Painful!

For high rpm horsepower that works at the detriment of lower rpm torque!

Miniram. All the rpm! But not on this project. Thanks
I’m guessing tune port injection which is a 80’s technology with the 350-305 Small Block Chevrolet V8 engines from that era correct me if I’m wrong
Correct. Thanks
I'm all for all of it, I have a '90 Corvette, L98, same induction, I'm dying to know what I can do and sneak past the computer.
Guys have done it. Thanks
I noticed that the outside edge corner speeds were dramatically lower. Wouldnt that indicate either widening the central straight or filling in the outer sides of the turns to even out the speed differentials at the corners?
I'm wondering if it would help to add material to the big side of the curve
You would think it would but in a bowl, lowering the roof may boost low and mid lift flows high lift will suffer. Thanks.
Very interesting Charlie. Sometimes you have no real option other than to increase the csa. Hopefully, each point will line up with an harmonic point, but you couldn't be that lucky.
You are right!
Those would make one heck of an induction system for a pickup or rv
I agree! Thanks

Ouch! That makes it much harder. Thanks
I did some work on harmonics. It is tuned to the 2nd harmonic. Thanks
Alot of information Charlie. I dont think anyone has done it. I was wondering how the helmholtz effect works on different intakes. GM did a enormous amount of work on the C8 Corvette and it produced a supercharging effect. NO supercharger.
It can be done. I feel with these long runners to get 6000 rpm may be tough. Thanks
@@servediocylinderheads I think you can do it if anyone can.
@@dondotterer24 Thanks!

In a different way but yes!
nice video i send a message via that linkedin site i hope you get it if not i have no idea how to get a hold of ye .thanks Travis

is it worth all the labor on the intake if the head is the resrition /?
Head flows 277 in this test
@@servediocylinderheads then YA open it up
@@RussellCompton-fh3gr Workin on it!
