When are you going to just show the video?



I Am not going to bother showing any video on this forum on this topic... IMHO it will serve no purpose.... no matter what my video shows your going to accuse me of rigging the results, just like you accused me of rigging my dyno readings and like you accused me of falsifying my testimonials..........if you want to see some video keep checking my youtube account like everyone else does....

Maybe the manufactures are not holding tight enough tolerances between the case and the crank

Maybe you're just plugging the thing responsible for keeping the crank shaft properly oiled.

Your 'clocked' engines are the only ones I (as well as other people in this thread) have ever seen get that dirty in that short amount of time.

First, you called them 'vacuum bypass ports', but you where chastised because you obviously didn't know what they were, then you called them 'oil bypass ports', now you're calling them 'oil reclamation ports'? Do you even know what reclamation means? How is the oil being reclaimed? What is it being reclaimed from? Where is it going once it's reclaimed?

LOL

And even if you it still doesnt change what is actually happening to these engines.,....Stock and modified these are taking in dirt thru the bearings, plugging that little hole does help with the issue....

Why would an engine manufacturer build engines with a defect? If the port draws vacuum, and can contaminate the engine, the manufacturer would lose a fortune in warranty claims.

do you own a quality 1/8th machine ? a buggy ? Truggy...do you race nitro ? if so what class and which track....have you ever owned a quality race .21 ? ever own a engine that makes more power then your stock RTR 1/10th machines ?

Warranty claims?  Accelerated wear would be hard to base a claim on.  Unless an engine grenades  right away, you're usually SOL.

Status: offline 		Since none of my engines have required any bearing replacements, and I have an O.S. .12 CV that came stock in my RC10GT Black tub...
Here's a video of that running if you don't believe that my first nitro engine still runs...
http://www.youtube.com/watch?v=VWG9Wc4OgyI

I'll just remove the seal on the 8.0 front bearing, all the parts that contain rubber like the carb etc, and fill the "whatever you want to call it" return, then reinstall the same bearing and try it out.
I don't have a bearing puller so I'll be heating it up and knocking it out.
Never removed a bearing from a nitro engine, but I've done plenty of bearings in 1:1 rear ends, same theory - heat the recieving end, put the installing end in the freezer.

If I find a port, I'll be plugging it with a syringe full of RTV.

Results will be posted.

Status: offline 		Savagecommander (and others)...I really don't understand what the problem is. What exactly do you need proof of? That blocking this port does anything positive? Why? If you don't believe it, fine, if Neal blocks the port on his tuned engines cos it makes them run better in his opinion, or seals them better, then again, fine...

What are you actually driving toward? That Neal doesn't know what he's doing? I can't see that working out for any of you, he has many satisfied customers and clearly is at worst, a 'good engine tuner'.

I just don't see what anyone wins by you or anyone else proving that the little hole is useful under some circumstances or has a different purpose. Who cares? It's clearly not REQUIRED to be open in order for an engine to work properly. Neal's just telling it how he sees it, it works for him, he isn't so stupid as to say something that he hasn't tried. Fine, maybe he doesn't understand exactly WHY he's seeing the behaviour he's seeing, or what the actual purpose or name of this little hole is, but is that really what's important here?

Personally, I learned something. That engines have a little hole that NOBODY seems to really know what it does, and that blocking it may reduce front bearing vaccuum. Am I now going to take my only remaining nitro engine and block that hole? No, of course I'm not, it ran great last time I ran it, but am I worried that Neal is giving terrible advice? No.

One thing's for sure, none of you seem to know the full story...at least Neal's experimenting and sharing the results. I would say the only person who has a right to challenge him on this subject is someone who...

a) Knows EXACTLY what that port does

b) Knows exactly what blocking it does

c) Can explain why Neal is seeing the results he seeing (because let's face it, he isn't lying about his own observations).

Be careful that you don't start arguing simply for the sake of arguing, or are taking part in a good old fashioned witch hunt.

Status: offline 		Just to be clear here.... I know exactly what that little port does......I said it back near my original post............however I do not have a proper name to call that port as I have never seen it ever formally labeled by any of the manufactures.........Even the engineers I deal with also do not have a formal name for the port.........But we all understand what it does and what the purposes of it are.........I called it every name I heard it called...one engineer wanted to call it a Vacuum bypass port, someone on this thread called it a oil reclamation port......myself I could care less what it is called as it has nothing to do with the actual mechanical issue we are seeing......Once that port is plugged we do see more weeping of oil out the front bearing.... makes a little extra mess, but the engines run much more stable and we are no longer seeing dirt get sucked into the bearing

Ha, dude, I pretty much lived at Rain City when I was 16. I was one of the first buyers of the MP6 Kanai, when you had to order them straight from Japan. I have competed in just about every single class, ranging from stock legends to 1/8th scale nitro buggies. Hell, I even remember the super truck classes, with T-Maxxes. I still have the first 'racing' big block engine I ever bought, an OS 21RZ. I've never really raced much SC, and I've never raced anything 5th scale... that's about it. Regardless, resorting to an experience based argument is pretty childish.

I still find it humorous that you think I've only every owned ready to run 1/10th scale model cars.

ok here is the deal, bought a big red dynamite .28 and could not get it to stay running for crap.  ok got on this forum and numerus people said to seal the engine: new engine i thought they were full of crap so i dun it    WOW cranked it up and ran perfect i was amazed if i get a new motor i do that now just because it asures me its double sealed. i do agree with the other statements but if they had the problem i had and sealed it i think they might change their mind.  as for hurtinging the engine well mines 3 years old and still runs fine, just a opinion my friend that i know works cuz ive been there

Robin at ERCM advised me to go with Werks fuel as well. I have a gallon and a half left of OD Race. Once my broken ankle heals I plan on burning that up quick. From what you guys are saying about Werks, I cant wait to order some.

Now this engine debate, there are only a few members here with the credentials to challenge Neal. Ive seen one that I respect more than anybody reply here. If your not a pro with vids to back it up....who are you to say.

Yes Neal runs his engines lean in his vids. Hes in the business of selling performance. Obviously hes going to do whatever he can to get the best performance he can on video.

I have also had heated discussions about Neal pushing his business on forums, many times, but as Foxy mentioned these are posted to back his argument and defeat others.

Now to anybody that may think I'm biased to Neal in any way, look up my old posts. We have had more arguments then I could count, but I believe he knows his sht. Right is right. Prove it or shut it.

I have a Big Red too, and - unsealed - it's about the best-running SH engine I have... I used to seal because people said to. Now I don't bother, and have no issues. Sometimes the whole "you gotta' seal!!" thing seems like a bit of an internet myth... Not saying it is, but IMO if your engine is put together right, and you tank, fuel lines, etc are all in order, there's no reason to have a leak that will miraculously be cured with silicone sealant..

Maybe your unsealed engine just had some loose screws or a badly seated O-ring or something, which fixed itself when you took it apart to seal it....

OD is OK fuel for most engines.......... unless your running a high output high RPM engine you will be perfectly fine..............

But I do want to say that I do not run my engines lean.....I run my engines so they are tuned to provide peak performance as does everyone else who competitively races a 1/8 nitro........If they were tuned lean they would actually lose power and RPM........Not to mention at 42 000 RPM there is no tolerance for a lean tune...the engines will literally self destruct in seconds if they are run lean... some of the fuels we run are below 5% oil...combine 42 000 RPM and 5% oil and there is little margin for error.. And right now I have no issues getting 30 gallons of hard usage from my engines with a proper maintenance schedule ......I just think most people here are just not familiar with how a high RPM modified engines is even supposed to sound..they hear the high pitched scream and assume it has to be lean..........However If a engine is tuned lean it will actually make less power and less RPM then a properly tuned engine............. so if I was wanting to make a engine look good the very last thing I would be doing is tuning it to run lean.........The tune I put on my engines is a proper race tune for the class of engines I am running...They will operate like this for many many gallons and provide an extremely long and reliable service life.......If I ran my engines lean, they wouldn't last a single day doing what I do with them.......Anyways not wanting to start a fight, but I had to clarify that my engines are not lean.they are just a class of engine many here are not to familiar with
