TNT pipes

[Don 79 TA]

thanks for the info...
guess i'm out with the setups we are running... (over 200psi)

The center bleed design adds trapping pressure so it doesn't like high comp
if your port timing is within the peramiters described it will make more bottm then most pipes with 35psi less comp
the motor doesn't care where it gets it's cylinder pressures.
High trapping pressure or from small domes.
But my theory is if you trap same pressure in the cylinder with larger domes you trap more combustibles you make more power.

Factory pipe isnt going to give up dyno time for this but ive heard the riva still has 2 dynos that Tim Judge used there back in the day One was brokin and needed repairs.It would be nice if one of the current large engine builders bought it and made it a proving ground for all others willing as well. Im sure riva hasnt used either in a long time,all their new stuff for racing development is 4 stroke and they are using laptop tuning and data logging on the water.The dust on them is prolly thick.With all these new designs in cases,pipes and billet cylinders with new port designs and cranks up to 16 mill.It would be great to have it at someones shop that was willing to share to prove they have the best out.
what dyno was used to produce the results you posted?

How the TNT pipe came to life!
In 92 I was a racer builder, sponsored by factory pipe.
Ross paid a lot of money in salary for a FPP emoyee to work with me for two weeks at factory pipe to build a pipe for my mod motor.
I won't get into details but I had all but keys to factory pipe to build it.
We built two pipes. They where finished two weeks before 93 world finals.
In winter of 93 I built all new engines with the I intro of 62t motor.
Keep in mind I was sponsored by yamaha soi got pre pro stuff
well the pipe didn't like the 62t 6mm 128 rod setup
so I began the hack and weld for months till I had something that pulled hard on bottom and reved to 8100rpm
well 6mm motors don't live at 8100 so I went to glen at skat trak and ran the guy to the edge of murder(typical racer) but when we where done they had the famous 15/19 thin blade prop!
Now we had 3 times the boat I was capable of riding.
So I had 10 pipes built.
Jeff aimes from splash magazine invited me to blaster pipe shoot out at lake mead.
I gracefully accepted after long talk factory pipe.
Well protec owner Dallas Baker threw quite the fit about tim tynanshowing up with a so called one off pipe that no one could buy.
FFP took my side said it's legal buyable pipe.
Well we installed pipe tested and had pipe off the boat in 2 hours.
To riva and tim judges full day to get there numbers
and won riders choice by all three test riders, one was riva sponsored!

So there is the story of how it was concieved!
In 95 I revamped it again for aftermarket cylinders.
Then the final pipe made in 96 the superstock
now for comment you can scrap factory pipe and there dyno.
I just got off the phone with Ross and he is going to let me use there dyno to do pipe shoot out!
We won't be able to start for few weeks do to Ross and I having heavy work loads and the dyno has not been used in years.

For dyno shoot out we are going to use a duel 44mm carbed 85mm STD stroke 62t motor with mild porting and I will give the complete motor specs when eng is finished.
Or If a well know engine builder wants to supply a complete mild built 85-86 mm STD stroke motor we will use it.

I would LOVE to see an X-Scream SS865 used for this test urr:

Yo X-Scream, you listening???

 

[tntsuperjet]

I want to use a STD cyl STD stroke motor because that's most affordable and popular packages out

 

[masterblaster]

well thats impressive as it is confusing,strange things happen in this field..Actual power ratings on a product will be a nice change,while your dynoing on the common stock cylin 85 mil flat top,great platform imho.afterwards you would catch a ton more attention doing the team scream stock stroke billet pv cylinder and the dasa lamey version. Im sure both will oblige. It will be a good day to see that dyno come out of mothballs, what does one of these dynos cost used anyway considering there seems to be absolutely no market for them at all with todays new skis ?

 

[SkiNaked]

The market is so small for both team screem and lamey motors. i have a Dasa cast motor and love it. But just not much of a market. Much better chance to sell if you target the guys with standard cylinders. IMO.

But the guys who have the Dasa and x metal motor are the most likely to drop $500+ on a pipe if it makes there $5000+ motor hit harder. Not sure the true number of motors like these out there but just my thoughts.

I have an 8mm 132 rod 82mm bore powervalve cyl motor
I will do b mod vs TNT on

 

[SkiNaked]

Lots of people that ride have enough money to purchase $500 chamber. Just don't need the power of a $5000 motor. Unless you are a flat water freestyle guy in search of a flat water backflip those motors are not needed for the majority of riding styles. The average freerider or stand up rider have the money to buy a 500 dollar pipe but have no need for a $5000 motor.

I can't promise we can dyno everything, see how well things go.
Factory pipe is being gracious enough to let us use the dyno, not sure I want to run out my welcome on it.
It's easy to sit back and want everything possible to be tested, but I think I have stepped way out over the edge on doing what no one has done.
I have never seen a race shop print there hp numbers or there porting numbers so people can compair.
If the old TNT pipe isn't good on new motors I will make it good.
The tooling isn't done yet, so the desing isn't done.
If we sell decent amount then I will consider building something for big motors.
I have recieved several offers to let me use there 1200cc GP based engines to build them a pipe.
They won't be cheap, but if I build it they will be good.
Or they won't be built!

If a pipe gets built for a 1200 wdk motor I know of a few guys that would be happy. I know one guy tried to get a custom pipe made for his motor and it cost him a couple grand and the thing was around 50 lbs.

this is the case in point.most guys who already have a ported 701 or BB already have a mod or limited pipe setup and at this pipes price point prolly will pass,not to say that its over priced,thats just the way it is.But you start talking about guys with 3k plus motors and your market share in this arena just went through the roof. stroker cranks are fading fast. There might not be that many out there right now, but with the power and cost factor of big bore billet pv cylinder,there could be especially if someone showed they were x amount more powerful than a stock cylinder on a chart with a certain chamber id think both would sell very well. isnt this how partnerships are started in this business. a few come to mind....lol

the market is new builds, people buying or building there first go at it.
these are the numbers, people who have there boats built are done, until there stuff is wore out.

Just posting info gathered from an old thread to speak to the three different chambers.
Original thread, http://www.x-h2o.com/threads/28540&highlight=tnt&page=6

Not sure if anyone noticed but there are three tnt pipes in this thread and all three are different model chambers.
The one for sale is a limited chamber, you can see the bracket was moved to the bottom, and the grinding marks on top from the removal of the old bracket.
The coated pipe is a stroker chamber, and the polished pipe is the superstock chamber first addition.
The limited pipe has more bottom but will sign off hard at 6600rpm.
good freeride pipe for somone to wants hard hit and doesnt care about RPM, but wont make a good race pipe.
There was only a few limited pipes made.

First 3 pics are the Limited Chamber,
4th pic is a Stroker Chamber,
5th pic is a SuperStock Chamber First Edition.
Last 5 pics are unidentified at this point.
Feel free to correct me on any of this BTW.

Couple more pics for comparisons and identification.

And finally some installed pics...

I stated that Paul at LPW could be helpful because he has had success w/TNT's on motors and Tim says they are NOT desigined for. I also made a comment about using Paul's dyno. (I should have left the dyno comment out due to history).

Paul has built alot of motors that screamed off the bottom all the way to the top w/high comp, alot of timing with Tim's chambers!!! He could very well be instrumental in this project.

Tim-if u would like to talk to Paul about his setup for TNT's, email me and I can get u in touch with him. gilwilliams101@yahoo.com

Several people know that the TNT did not work for me and it is because I did NOT follow Paul's directions completely. If I had-who knows. I know I have ridden some of Pauls setups with TNTs that were awesome-so he DOES know how to make them work!
