I know it is a late and perhaps pointless response, however...
I'd like to suggest that the operative word is not "attention" but "respect".

 

Now you are twisting my point.

Does anybody have any reviews of the M7 TB? Like does it give quicker response, less noise, more power, etc.? Any differences between 59mm, 60mm, 62mm? Just trying to get this thread back on topic.lol:

 

yes, thanks for pointing that out - i CURRENTLY work for a predominately stereo-minded shop, but i'm the performance division that you don't see online.... i used to own my own business as the 3rd largest RX7 tuner in the country (you know, those twin turbo rotary things :impatient ) and imported Skyline's of all years into the US - owned 5 of them at age 22 - and sold the business in May of 2005....

so thanks for doing some research on me, might want to look more into it before making the statement that i don't know my performance business when it IS my business to know it

niiiiiiiiiice - i bet Peter knows you by name like he knows me, hahaha

yeah, come check me out, wait until its all actually complete first though, can't really do anything in the state its in right now (torn down to NOTHING on the inside - motorwork is done, however!)

 

so is there a core charge... and 60 or 59. Will the 60 throw any lights.... and ofcourse the flat spot.

 

I guess i have to jump in and clear up some confusion regarding the
different sizes of our TB, and why we had to raise the price on the latest version. And of course the core charge.

When we started to design the latest version of our TB, many variables where looked at and considered. We started the process with an extensive CFD study
to learn the actual air flow patterns in the Throttle body. We played with different angles and plunge depths of the velocity bevel, and we changed the thickness of the center rod to see if we could improve air flow and in the same time minimize turbulence in the throat of the TB. All these tests led to the TB we now offer for $399.00 Some of you asked for more testing and we gave it to you big time.

The problem with the 05-06 has been a tendency to throw EML and CEL lights
necessitating a different approach....smaller is better??? Yes the 59mm and in some instances the 60mm will work beautifully on these cars allowing more airflow without tripping any lights. The 60mm has become the defacto standard for us as it does not evoke yo-yo, flat spotting or any other problems. The 62mm unit is for ultimate performance, but does have some flat spotting in certain car/ecu combos.

As for core charge, the TB is an expensive part at almost $200.00 and we need exchange cores to make new TB, and without it, there would be no way to keep the program going.

Please visit our website and take a look at Will's excellent write up of his
CFD study of the TB.

That's all I was wondering dude. Don't get your panties all twisted . There have been a lot of "opinions" floating around with no real background or experience to back them up. I was just trying to get your claims of being a pro clarified.

And by the way, the sarcasm was noted and not appreciated.

Thanks from one "pro" to another.............

 

240 whp - wow.

 

so, i'd like to know.... what OTHER company goes through this much tuning, engineering, designing, fabricating, and then has the energy to communicate their results professionally on the internet with people who are so opinionated that they immediately take sides with the first person who says "THIS WORKS!" or "THIS SUCKS!"

i hadn't seen that chart before, Peter, thanks for that.... thanks for making the point, and keep up the good work!

 

so... are their any dyno numbers?

 

You know as well as I do there aren't any numbers.

 

Edit, oops.. I was going to put a link up to the whole article on the website but it's already there. Nevermind me!

:whistles and walks away:

someone did a test of TB's I'm pretty sure the m7 was in there...wasnt it?

 

Hi Rally...

Yes one NAM member did some testing a while back, this was done on a previous version of our TB. And to be really honest, the test put us in 6th gear
and we found a "Better design" to the TB.

again... don't take this as bashing... im am genuinly asking if their are dyno numbers for the TB yet... thats all...

I see a very fancy flow chart... but sometimes more flow doesn't equate to more power... and i am just genuinly curious if they have seen any power gains.


Seriously best of luck!

 

Thats alot of money to spend if it produces 1 whp.I hope its more than that

 

VERY TRUE... I hope they didn't spend all of that time reengineering the throttle body only to find 1-2hp... that would suck...

so i am hoping seriously serioulsy hoping that they are making more power

 

This is the problem.For 1-2 hp at what hp? 5500? Good mod for racing maybe or bragging rights.

 

So, I guess that's a complete guess? Lemme insert something here, theory-wise:

Given the dual velocity stacks and the shaved butterfly, more air will enter the TB at any given degree open. This means more air in the intake manifold and more power generated, presumably. BUT, this power will be available EVERYWHERE along the powerband, since the resistance to flow is apparently less at every degree of aperture. It may not be the same increase everywhere, but power will rise across the powerband, in whatever quantity it will. I actually believe that more power will be gained lower down with this mod, because the area is relatively more open at lower angles. Hope y'all get me.

 

The question of how many horsepower is very dependent on the car. On a stock vehicle, probably 1-2. More on a modified car. Think of it in terms of another intake component. If you add any intake to a stock car, you get a few HP. If you add the TB to that equation, you get a couple more.

However, take a car that has an SC pulley installed. Well, that intake will produce a few more HP on that car. The TB will produce a few more as well. To really get into what a part does for the car in terms of horsepower, you need to look at the whole system. An AGS with the M7 throttle body will produce more power than with a stock throttle body, but not much more. Add to the demands of the engine by adding a pulley, porting and polishing, etc. etc. and you will see the gains grow as the car demands more air than the stock TB can efficiently allow through.

This is not meant as a power adder for a stock vehicle, though we've seen that it still adds some responsiveness to the throttle even on a stock car as well as some noticable power increase. The throttle response is very noticable on a modified car. It's purpose is to allow for the completion of a modified and efficient intake path when coupled with the M7 AGS. The effectiveness is not limited to the AGS, certainly, but it helps to remove as many obstructions to the intake path as possible.

 

so i guess this is a complete guess... well let me rephrase that... an educated guess... well at least its a well thought out one... but it still ends with guess

 

true... just like any car... its the same as putting a 3 inch exhaust on a stock car vs putting it on a twin charged car... its going to make a big difference on the twin charged car...

I was just wondering if you guys have done any REAL testing... thats all... if it hasn't been done yet... no biggie... just curious... I would imagine that this throttle body will make the same amount of HP as any elses throttle body...

 

Well, real testing again is subjective. I'm not aware of any dyno tests on just a throttle body, as it's typically seen as gravy to a much more extensive meat and potatoes mod program.

I think that to a certain point, you are probably right. At least within measurement uncertainty. However, beyond a certain point, the M7 specific developments will certainly provide an advantage over what anyone else is currently providing. It's all in how hungry your engine is.

 

So the throttle body produces more power but not much more. While the entire purpose of the throttle body is to make a completion of the intake path on an AGS car.

That seems confusing to me. It doesn't make much power but completes the flow path of the AGS. Does anybody remeber what kind of power difference the AGS made....

But then you go on how it works better on a highly moddified car. So unless you have a highly moddified (un-warranty friendly) car the TB is worthless or is the AGS worthless or are they both?

Not trying to "attack" M7 just trying to understand what they are saying.

 

Does the M7 throttle body open perpendicular to the flow like pictured in the flow analysis?

 

their are theories... (which i am admittably inexperianced with) that do state that sometimes it is better to have a little more turbulance on the intake side (before the cylinder head) to ensure proper fuel atomization... just a thought...
