Fathouse Ihave one here with your name on it :P

Robert yes the throttle body is on a 15 degree angle towards the front of the car to facilitate intercooler plumbing.

There is no info on my website as of yet, but there will be shortly!

Once again yes it has been dyno'd on many different setups.

 

Divulge a little on your CFD work.

Program used

model type

mesh properties

boundary conditions

You know, just the basics.

Can't wait to see the cut-aways. Can't wait to have my mind blown.

As for being the company with the most experience on a 4 cylinder... I don't know, lots of formula Atlantics, professional teams like Cosworth, Honda, Toyota and Lotus to name a few. That's a pretty tall claim.

 

03white GSR : read it again

"When it comes to aftermarket 4cylinder intake manifold technology: we have the most experience period"

You seem to be fishing for a internet fight, but on the other hand, it also sounds like you know might know what you're talking about. Unfortunately you'll have to wait like everyone else.

 

Sean, what gains did you notice. Please shoot me a PM if you prefer.

Felix (Rochester)

 

Cosworth, Eldelbrock, I'm sure there are others...

They all make 4-cylinder manifolds for the aftermarket. The are stocked with teams of engineers and massive budgets. You made a TALL claim.

I'm not looking for a fight at all. Just not buying into hype.

If your product is what you say it is, these words shouldn't come across too threatening. But then again, if you were threatened by the words, I could see you sending PMs of condescending nature and of poor tack. I expected nothing less...and got what I expected.

 

Cant wait to see this thing in action Marco! I love my Magnus street manifold BTW.

 

very nice looking piece

 

Looks exceptional!

 

I searched through all of your recent posts. I've learned something in life, never underestimate anyone. I also, learned to never ever open my mouth until I 100 percent know the score. I do appreciate that you don't buy into hype like everyone else though, truly I do.

I'm sure this is what you are looking for in this picture.

Without giving everything away about how we do things here, I've shrunk it on purpose. That should answer most of your initial questions. But so as to not underestimate you, I'm expecting there are more questions to come.

Thanks.

 

When is the official release date for your intake manifold?

 

im putting this on the wish list..

 

Marco, you have not underestimated me. I know very little when it comes to real automotive type engineering. Like I said in in the AMS thread, results speak louder then math. There is still plenty of hope to prove your product to myself and other discerning potential buyers.

Looking at that picture though, it was my "best case" judgment of what you were talking about. It looks to be a 3D steady state analysis. I admit, you have disproved my initial thoughts in that I was skeptical of any CFD work actually being done.

Boundary conditions are likely a mass flow inlet with static pressure outlets
All 4 ports flowed simultaneously
No wave propagation was simulated
Mesh looks course, but display properties don't always duplicate mesh properties

In the end, you've got a computer based flowbench with all 4 ports being flowed at once. In that picture anyway.

In case anybody is interested in a trick that can accomplish about the same thing, tape some streamers to the outlets and hook a blower to the inlet. Get the streamers to match in oscillation frequency and you should be pretty damn close to this test. How much it applies to making a good manifold on an engine that is subject to pulse flow is beyond me.

 

"Math" as you call it, is used to prove the concept. This is just one of the engineering principles that we have at our disposal, not to mention others.

You thought I was full of ****, I can assure you we are not. I'm pretty serious, and so is my hairstyle.

It is course, in that one. Mind you that is a screen shot of only one of multiples. But you are not correct in all of your assumptions.

Not exactly what we were looking for in our testing. Also, to assume you can accomplish the same trick with streamers is the kind of misinformation I've been trying to fight on the internet since its inception. For someone who knows as much as you say you do about CFD, because you do know a hair more than the average guy, you should know better that we're not that interested in what the "streamers" look like when they are escaping the ports. And please don't undermine our research by suggesting such things.


More pics to follow!

Thanks

 

If you really wanna go with an old-school F1 style way of checking air flow distribution; spray riboflavin into the air stream entering the intake and you can view the direction of the airflow using a black light

 

I see you escaped from the vortex...welcome...
