Why don't I ever see dyno's?

masterbator, You claim to be some kind of expert. But your coming across the wrong way. I personally think you have too much time on your hands and you're using your Google search function way too much, to gather information to make it seem like you know what you're talking about. Once you've been in business as long as TNT has and gained some actual knowledge and experience, please come back and post. I for one was there when some tuning on this pipe was done back to back with a power factor pipe, it makes more POWER period. With that being said this will be on my to buy list. O yea they come with a money back performance guarantee, who else offers one of those?
 
On the detonation side. The human ear cannot hear detonation until it exceeds 50%. On a two stroke with a trained ear the above average tuner can't hear it till its in the 80% range.
Bearing damage starts in the 30% range.
Pipe tune becomes affected in the 18-20% range.
Every free ride boat I have data logged with under the plug set sensors has exceeded 70% Det on pump gas with 165psi comp or less.
As almost all PV engines have a 13to1 or greater corrected compression ratio with PV CLOSED.
Oh. Piston etching and some putting doesn't become prominent till you exceed the 65% range for long pulls. Aka racing.
So in free ride you won't see any signs of Det on the Pistons and you could be in the 70% range and never know it until you have a rod or piston failure.


Interesting info.

What would you recommend for, what sounds like most of the freeride guys, to combat this high level of detonation? If we can't hear it, and we can't measure it without $20k worth of data logging equip, and the engine internals won't show signs of it until failure? Is it
Just the nature of the beast and we can't change it, or do we need more fuel, less timing, etc?

Not bashing, not saying your wrong, I'm extremely curious and like to learn if it is info you are willing to share.

It's hard to hear over the intake and exhaust noise. At full power it will sound like a high pitch buzz for about three seconds, then the engine will shut down with a stuck ring.

There was talk at one time about a stand alone ring sensor that installs like a washer under the sparkplug to detect detonation.
I have never followed up to see if it ever made it to market.
It is available as a part of much more complex data loggers but it would be quite valuable all on it's own.
 
swapmeet.. its deff not the end all be all,Et and Wdk and one other all have pipes and custom manifolds coming out for WF,cast and billet mani to take it up a level. The v2 may make more power somewhere over the pfp but not enough to back it up with a factual # apparently,its easy to talk it up and get more guys to sell their pfp than to prove it with a # that is min gain in one area and a loss in another. kevbo theory in this thread coming true.

Its really funny to watch the tpe clan typically rally in defense of any factual requests. The cronies fav reply always is "dude it just rips and makes more power" motor,pipes what ever the case. Really how informative i feel enlightened now.. your masterful knowledge astounds me .. really your rainbow is just taller. Do we need aptitude tests here to make tuning statements or ask a question. IF you read a book to gain knowledge in school to get a degree,is it not your knowledge cause you didnt write the book,you guys are good for a laugh ill give you that.

Seriously laughed @ "Really your rainbow is just taller..."


I kinda thought the same thing about reading to gain knowledge. I mean, the guy who doesn't do research (god forbid Google) to be more informed to discuss something is really the problem right? I mean, how are you gonna rip a guy for educating himself?
 
because in their world if you didnt build the motor or the pipe,or tune 100s of them,you know nothing... Short of tim and phil 99% of them cant tune their way out of a wet paper bag, Thats why they all run to them,helplessness abounds them.lol How many times do you have to tune a 2 stroke ski with 2 carbs and one pipe with water injection to aid you,to have it figured out? 20 50? 100? 1000?

MB, have you ever been tested for Narcissism?

This says you need 5 or more traits and there's at least 6 by my count.

Narcissistic Traits
A pervasive pattern of grandiosity (in fantasy or behavior), need for admiration, and lack of empathy, beginning by early adulthood and present in a variety of contexts, as indicated by five (or more) of the following:

A pervasive pattern of grandiosity (in fantasy or behavior), need for admiration, and lack of empathy, beginning by early adulthood and present in a variety of contexts, as indicated by five (or more) of the following:

  • Lacks empathy: is unwilling to recognize or identify with the feelings and needs of others
  • Has a grandiose sense of self-importance (e.g., exaggerates achievements and talents, expects to be recognized as superior without commensurate achievements)
  • Has a sense of entitlement, i.e., unreasonable expectations of especially favorable treatment or automatic compliance with his or her expectations
  • Is interpersonally exploitative, i.e., takes advantage of others to achieve his or her own ends
  • Is often envious of others or believes others are envious of him or her
  • Requires excessive admiration
  • Shows arrogant, haughty behaviors or attitudes
  • Believes that he or she is "special" and unique and can only be understood by, or should associate with, other special or high-status people (or institutions)
  • Is preoccupied with fantasies of unlimited success, power, brilliance, beauty, or ideal love
 
Everyone bow to masterbater here, he knows all. Dude if you know all that you claim to, why don't you make your own pipe.... Then you can put your motor on a dyno and give everyone these numbers that you have such a hard on for. It's pretty clear that you don't know when to shut your mouth, keep talking, you're just making yourself look dumber. You're the type of person that runs the knowledgeable people off of this forum. For once in your life please shut the fu** up!!

Well I don't have any ties to TPE or anyone else.
I have worked with TPE on one boat for surf slam as a combined effort started by tigercraft.
But that doesn't make them my cronies.
MB. You do seem to have a hard on for any of them and steer towards WD and E tech.
I hope WD comes out with a better pipe then there old one because it was quite bad! Considerably less power then a factory B pipe with mod chamber.
Let's do a pole.

People please state your personal vote.
What do you want a dyno chart that states this pipe makes x much power or graphs it out as the most power of any pipe
Or a money back guarantee it will be the best pipe you buy or return it for refund?
 
This is a motor dyno thread. I have said nothing sideways or not polite until the cronies start in with the same old nonsense

Narcissistic.sounds like the bulk of the X,maybe thats why they named the last ski movie similar to it...lol

the last wdk pipe was not the best in class eh,looks like the new one was developed by someone else on a high end dyno,not a waterbrake. 3 diff size stamped chambers for diff cc motors and custom billet mani that flow more power than pfp mani. Et looks to have their own mani and pipe soon also,I have no preference to either,just think its cool the market is opening up with pipe choices this yr more than ever. really who wouldnt be stoked to hear that?

A money back guarantee is cool, but I can go to walmart and buy 100% cotton underwear and return them dirty,but they come with a label that differentiates them from polyester panties and saves me the trip. Especially since you already have it... Anyone that says they wouldnt like to see the power comparison chart to their current pipe just doesnt care or understand tuning cause they wont be doing it.

Well i personally plan on running a TNT pipe ,not only because my pfp dry pipe inner chamber broke and turned my power band into a turd .i like the works like characteristics of the stainless material used and its heat characteristic not to mention the tunable options and strength,wonder how all that look on the old dyno
 
Quinc..lol they pretend like they dont read all the threads with the most drama first,specially the ones where good tech info comes out in it..

little franny.. Det is goin to happen to some extent in a freeride setup no matter what if your making good power,we all just hope to keep it under where permanent damage takes place. A pfp dry pipe has less bottom end power and response,so the largest majority of them are setup on very high cylinder pressures using oxy race fuels that cause the pipe to act differently at lower rpm high timing settings using tl ign,that have much safer lower final timing. also these high octane fuels contain det reducing additives such as lead.So they make gobs of power. This gets the pipe through the flat zone in the rpm much faster and gets it on its hit or torque peak quicker. The vast majority of wet pipes in our freeride, world run on low cylinder pressures,low oct pump fuel with ethanol. They run simple ign that dont provide high timing in low rpm or safe final timing to resist det or let pipe rev out. While you may not see signs of det on the piston,many guys wonder why these larger cc motors setup like this on a wet pipe go through wrist pin bearings constantly and eventually snap rods in half and see there cylinder near cut in half by broken rod. It would be nice to see #s on these kinda pipes and pfp setup how many end consumers will end up using them...

Where is the dyno chart for WDK old pipe.
PFP pipe? Or E tech new pipe.
Seems to me that you are doing for them exactly what your accusing others of doing with me. L

MB last post cracks me up.
How many people know the RRP pipe is a dead copy of the outer water jacket of a PFP??
One is known for all low end and signs off the other is all top end.
But they are basically the same pipe!!
Same tune dimension different volume. Most have zero clew how volume affects a motor.
How many of you think large volume pipe kills throttle response??
Wet pipes cause rod failure is the biggest stretch of the truth I have heard in 20yrs.

Just to clarify for other readers, what I have said is regarding dyno testing complete packages to show customers what they can expect for the money. I did not talk about one specific component or whatnot. I do however like the tech info that have come out of this discussion, but I feel that the anti dyno crew with the exception of a few have contributed little towards getting that info out. It is only because some people asked the right questions and somebody with knowledge answered them.
