this might be offtopic.. but why do random people argue with shops who have personal experience..

 

Because they also have experience and dissagree. now wheres that pic Rob? haha

 

I'm not arguing with a shop. I'm arguing with an opinion. And Rob's opinion isn't backed by fact. I'd love to see a dyno showing something that is backing up his opinion, but it doesn't exist. What might exist is a dyno that shows improvement over stock, but that isn't saying that it is better over the 4g93. Show me two dynos of someone who has put both on.

Oh, and then lets argue about power curves and the benifits of torque at specific rpm points! It never ends, see? It can't be proved either way in a conclusive manner that would satisfy you.

In going along with what N1te has said, the 4g93 has larger ports. Period. If a picture can be shown of a ported 4g94 with larger ports then fine. But this is not the end all of the discussion. The 4g93 is a superior design on the merits of design. It is shorter in length from the opening of the throttle body inlet to the exit of the ports. This produces a better air flow for our engines than the larger 4g94. This better airflow equates into a faster airflow.

Here do this test: Take the 4g93 cover all the runner ports and fill the thing up with water. Ok, now do the same thing for the 94. The 93 will have less water. Why? Because it is smaller.

Now what does that mean, Fox? Well let me break it down for you. It means it's smaller. Does this change the amount of air that is brought into the engine, Fox? No. What this does is act partially like a air accelerator. The volume doesn't change, it just has less space to occupy therefore it moves into the engine more quickly.

Unfortunatly, I'm not sitting in Housten at NASA so my access to my 3d air flow capacity meter and my volume mass gauge aren't at my disposal. However, fluid dynamics from physics and basic engine knowledge of how a lawn mower works support this cracked out therory I have.

Like Rob said though, we can agree to disagree agreeably. I'm not tossing down or throwing names here. Or is it the other way around... I'm not sure what the lingo is these days, anywho... We are being respectful. Again, love to see a pic. It doesn't prove jack but lets see it anyway so the fan boys can be appeased in their golden calf another day longer.

PS- I'm getting a little sick of reading all this blind worship from some of you guys. And I'm pretty sure I'll be either reading a PM from a MOD warning me, or this post will be deleted but come on people. It's just opinions. And who are you to say that I can't argue with an opinion just because it comes from Rob?

PSS- This post follows the rules Mod's, this is discussion concerning the choice Dave has to make concerning his build up. If you disagree with what I am saying then so be it. You have the power to delete just use it wisely. I just hope someone gets to read this... espically the golden calf part... didn't take college level biblical studies for nothing, god nab it.

 

Shingen. I do not have proof and nor do you. Power curve in theory should be better top end on a 4G93 manifold but I THINK YOU GIVE UP LOW END. This is what others have reported. As for the ports, there is not enough material on a 4G93 manifold to port to the size of a 4G94. Believe me I can care less except please do not claim blind worship of us. It is not us vs 4G93. But right now you are ask people to blindly worship 4G93 manifolds. Think about it. Someone should do dynos back to back. Maybe I will utilize a flow bench to illustrate things but I do not have a 4G93 manifold. We had DemisedGabe's ported mani from A2 so we took a picture side by side. I guess you and I will just have to let other's decide for themselves and try each. I sell 4G94 but I could sell 4G93s. I just don't want to cause no one has proved it better yet. I am open to it though!

RRM my friend Paul gives you funny look!




On a side note, thank you nam. When you get back we'll sit back and have a beer. Do you have a girl waiting for you back here?

 

Silens, thanks bro. Appreciate it.

 

N1te anytime bro. I'll PM you and Fox once I firm up the date I'm leaving country. is always good. Looking forward to it. As far as having a girl waiting for me, I've got one here, one in Germany, and two or so in MA . Intercontinental pimping N1te, lol. But strangely enough not one in VA, I've gotta fix that when I get back.

 

Paul give everyone a funny look.

That is a pretty funny looking face, lol.
Did you get my PM ROCK?

 

The 93 is ported?

 

Thats a good point. The 93's I've seen on other posts seem to be alot more open that that. Maybe I'm crazy though.

 

I found this pic in the Lancer/Mirage forum. This IM is ported. It looks like the one in the other photo on this thread isn't. Now, does this IM look like is has larger openings then the RRM one?

 

TO clear that up. That was A2 idea of ported yes. Was it NO!. Regardless having them next to each other and measuring thickness of material and ports with calipers etc showed that 93 runner material is not thick enough in some areas to port to the size shown on the red manifold.

Thanks for clearing that up Rock. I'm sure alot of us that planned to purchase parts from A2 are glad that we didn't. Its the pics I posted, the 93 was pretty heavily ported. Are there any risks of the mani failing due to the thickkness of the metal in the runners?

 

Sure it is possible. We have accidentally ported through a runner before and had to trash the manifold.
