I truly love thought provoking threads like this.
I’m sitting in the arm chair on this one. I truly don’t have the want to go get a few $300-$400 mills to test with. That’s what I run and would want to test in real life if I choose to do so. Ill sit and read what come out in the weeks and months to come before I decide what to do.

My question is:
Who’s running / winning on the national circuits without a pressure line?
I would think if it made a difference, even a little one, the folks with money and mills to test with would have done so by now. Or have they?
 
I bet it would be best in something that uses a consistant rpm, maybe a plane or a boat? Just seems odd to me in offroad where with all the bouncing and shaking it wouldn't work well without a pressure line.

But I'm like Ed...you won't catch me testing this one out.

I think Gil Losi JR was one of the first to use it, Brian Kinwald, Adam Drake, and many others. It has also been used by Chris Tosolini and other on-road guys.

IT changes the power band and may not be better. The article explains it and it makes more power down low, where in some cases you wouldn't want more power (low traction, dirt).


If you care to explain how properly tuned engine could be ruined by this I'd like to hear that. I know, and I'm pretty sure the list of drivers above know, how to tune an engine. :) If my engine is running correctly and at the same temp it's difficult for me to understand how that will ruin an engine.
 
Umm, hasnt anyone had there pressure line fall off on accident? Well, I have and knew it because the engine died. Would riching the mix keep it running? I have a RS4 from a few years ago, had an awfull can muffler and some 3 piece manifold, but it also had a pressure line?.

I never said I could properly tune
The truth comes out..... :D

I held your recent issue with tuning tips up to my forehead and meditated on it last time I ran but it didn’t seem to help.
 
Eddy,

Don't get me wrong I enjoy these kinds of threads to, but I'd also like to know more about the testing, not only about this undisclosed "device" but also the engines being tested, the periods they where tested (5mins, 1hr, 1wk...), and other details such as onroad, off road and so on.

Derek the point I'm trying to make is that you've said just a few years back pressures lines where an option. You and I both know R/C has came a very long way in the last few years every aspect of R/C's. If something that was once an "option" is now a standard how can you explain that? You've said bigger engines do need a pressure line yourself. Since I've started this site I don't recall reading a single thread about someone looking for a smaller engine, they are always wanting a larger one thus the need for that pressure line.

I look forward to reading this article, however I'm going to do what I think alot of others are doing and that's taking the passenager seat on this, with the lack of any "real" proof I see this as nothing more then an theory. Hopefully you or someone else later on can actually prove it.

Most of the time you here the need or want of a larger engine, it’s for off road or bashing. Racing has set engine limits and folks are always looking to improve the performance of the set mill size. On-road racing for example is for the most part set to .12 and off road set to .21

I do agree that a lot has changed in mill design from just a few short years ago. For one the RPMs have close to doubled and the HP as well. Most of this happening in the upper RPM range. Hence the need for a smother power band in the upper range. (Pressure Line)

If there is no need for a pressure line then why is someone spending time developing a “Device” to ?Replace? it?

It changes the characteristic of the power delivery. It IS USED by racers. It was a theory maybe years ago, but since I actually have a tool that shows what all the racers said it changed...is that still a theory?

Also we tested this on a .12 and on the dyno, the drivers and pro's I spoke with about it actually have been doing it for years.

I can't explain why the changed happened, but maybe it had to do with what people wanted or "what everbody" was doing. But I think it has more to do with engines going faster and fast and the desire for PEAK HP and not more useable.

Why do we use standard and turbo plugs?

Assuming one could add something to an engine that took advantage of the increased power down low without a pressure line and they return pressure at a set point to put more fuel in the engine when it really needs it (high RPM) and that device added more power at the top and 7,000 RPM more from 42 up to 49,000 RPM...why wouldn't you want it.

Simple things make big differences.

Absolutely I still think this is a theory - you've provided us with nothing more then an undisclosed test with no other information.

This is no different then the kid claming his t-maxx will pull a full size car, i'm not buying it. Show me all the facts and then I'll change my mind accordingly, until then this nothing more then theory.

I will say this, if anything you've done one thing and that is me keeping an even closer eye on your mag for a while, waiting to see more info about these tests and the new "device".

Assumeing it works......
K.I.S.S.
What would happen if this unit malfunctioned during a race?
How durable it?
How much does it weigh?
Does it change fuel consumption?
Will it decrease the life of a mill?
Does it impede on any other resources such as battery life?

Just like any other product, one needs to weigh the good against the bad and make a decision. There are many other considerations other then more power or smoother band.

Are you serious? The "device" is still off in the distance. The facts are printed in a magazine. Unless you want Jesus himself to post it somewhere I can't help you with any more proof. Me telling you something that a magazine tested is probably a little different that a kid with a T-Maxx that goes 100mph. That's really a bad comparision. What do I have to gain from testing something that people actually use and back that up with data.

If it was tuned for running with no pressure it is near impossible for it to malfunction and cause it to run lean.

Fuel consumption is something that has to be tested since there are so many things that affect that.

Assuming we're talking about the little "device" it will weigh little, shouldn't effect life of an engine, but in racing that isn't always the concern.

If an engine is tuned correctly and not running lean it's life span is up to the user.

You're asking all valid questions, but before you guys keep beating a horse you haven't seen–read the article.
 
Derek - You're not reading my posts. The fact is me, myself, and I have NOT read your article as of this moment. So I have not seen any facts, I promise I'll pick up a copy of your May issue and see what kind of facts were printed. As of right now all we've got is you saying there is no need for a pressure line then saying you can't go into the details of it.

Don't expect people to embrace you with open arms without any more facts then what we have in front of us at this very moment. As for my comparision it hits it right on the mark.... going right back to what I just said both parties are claiming one thing but at this point I have no proof of either being true.

Like I said I'll keep an eye on the magazine, after I've seen the facts I'll reply accordingly.

EXACTLY! Thus why I'm seeing this as simple theory until then.




-Michael
 
The "secret" device and the no pressure line set-up are two different things. Re-read Derekbs first post mentioning the device.

I've read the article but I'm sticking with my pressure line. Why? Because I am happy with the perfomance of my engine as it is. Though the increase in power is easily seen on paper in a graph, as a basher I doubt I would be able to feel the difference.

Alright I've read all of this,What date is the magazine suppose to be on the shelve's,is there any direct links to this "device",Since the device is being printed in a magazine,why not just tell use exactlly what it is,XRC is releasing info,why not just spit it out and give us less of a headache.
 
Got Nitro,

The device has NOT been released. From what I gather the article only makes a claim that the pressure line isn't needed in todays R/C's. From what I can see nothing is being reviewed...yet.


sweetdiesel,

You make a valid point about the two subjects being different, however they are much the same as well. Derek said in this thread that his results included testings from an unknown device, thus bringing the two together. At any rate as I've said I see this all theory with or without a device until I've read the article.
