Some of you may know me some may not But to clear the Air I am Tim Tynan, the builder of the TNT pipe.
Recently I have been getting beat up about making more of the TNT pipe.
Actually for the Past 3 yrs been asked to build more.

I have put some work into this and have all but pulled the trigger on building more. The draw back is the new pipes will be stamped.
The big question is what pipe to build? I have looked at most the forums and the pictures and see every version ever made and almost no one notice there different.
If you want to see three versions, there is a tnt chamber for sale for 500 on this forum that has been for sale for couple yrs looks like, that is one of the original limited pipes that the bracket was moved to the mag cover.
the polished pipe is a first gen superstock chamber and the coated pipe is a stroker chamber. None are the Gen 4 superstock chamber that is the best pipe for racing. The superstock chamber is smoother power and revs higher then all the other pipes. Still has great low end but its not violent hit like the limited or stroker chambers had.
So the drama is what pipe to build?
Here is our options, if i build the tooling for a limited, we can have both the stroker and the limited pipe, the difference would just be 10mm shorter center section and slightly shorter headpipe.
The superstock chamber has all different cone tapers and will not work for crap made longer as to replicate the limited pipe length, there for it would be one pipe to serve all needs.
The pipes will be sold by two dealers only, Blowsion and Watcon.
Chambers to complete systems.
If you all wonder why pipes are so expensive here is a break down for you.
Tooling is 5,000.00 then you have a setup charge and price per parts.
so to build 25 pipes I am looking at a 10k investment plus my time.
There are less then 200 total tnt pipes ever made, and 30% of them went over seas.
We have to make 100 pipes to make them affordable, with todays market I dont see 100 pipes selling in less then 2yrs.

Plan on setting up a tnt pipe test in antioch CA, where you can install a tnt chamber on your boat and have support by the pipe maker to make sure its installed and tuned properly and see if you like the pipe.
The date of this is TBA, but look for it after WF.
We will have two pipes available, superstock and limited.
There will also be a second pipe test done in central coast of OREGON and same support.
Please keep in mind, we will not have time in a day to install a headpipe and maniforld, so all who plan on testing will need those items installed and there boat ready to go exp for chamber.
TNT pipe uses the stock exhaust hose from water box to OEM exhaust system,
 
tim welcome to the x forum
here you will find the hardcore guys
i think its awesome that you are offering a "demo" for your pipes
i had one of your piped 10 years ago but i dont think i had the motor to pull it so i sold it
also had a tnt water inj system
did you have a shop in havasu in 97?

I have to say it is AWESOME to see you on here. I have seen TNT chambers before, but had no idea there were different versions or that production was so low.

Before you pull the trigger on stroker and limited chambers keep a few things in mind about the market now. From what I see racing is not the primary market. People are spending thousands on "freeride" setups. With no displacement rules engines are getting bigger. We see lots of big-bore stuff. Big bore +5mm strokers are almost common (we have four at our shop and parts to build two more). GP800 swaps are getting more common. At least two people are working on ways to put Superjet B-pipes on GP800 motors. Also Big bores aren't just 85mm anymore, some are 90mm! 845cc stock stroke engines from two (or more) manufacturers.

At the top of the heap we have four manufacturers (DASA, Team Scream, Bun, ADA) making 950-1050cc 62T based billet cylinders.

My point is, let the stock displacement guys have their used B-pipes. Go for the big fish. Make a pipe for the 850-1050cc guys.

Just my .02.

Personally I see no hp gains on anything 62t based with over 85mm bores.
The transfer volume just isn't there.
Well there is always the option of building cone pipe for the big motor guys.
To be honest I don't think there will be more then 50 of these big monster twins build in a yr.
So it's hard to justify all the work to build a pipe for them.

Thanks for the warm welcome.

FYI, i would be happy to design pipes for any of these motors.
But just like most of us, I can't go to work every day for free.

I am getting ready to run a blaster mod chamber on my 85mm SS lamey motor. How would the TNT chamber compare on this set up? Any interest in doing demos at the Daytona freeride in January?

Yep. What he said.

I see people complaining all the time about a new $700 Factory B pipe. They should be happy to be able to even buy a pipe at all for a two stroke.

Most people have no idea what it costs to build, stock and maintain inventory, sometimes taking, like you said, two years to deplete, that is alot of capital to be stagnate.

I think you need to re-visit what DASA is doing with transfers for the big motors.

If you compair the great two strokes to water two strokes you will see what I mean about transfer volume.
Dasa did great job adding as much transfer volume as possible.
But it's still only 30% of what a high powered two stroke should be!

I know what it should be, every design has limitations.

I was specifically talking about your comment of "no hp gains on anything 62t based with over 85mm bores"

"We" and I, beg to differ.

Just wanted to touch on that.

I would love to see some collaboration on a new engine design! I mean why not. If you think about it most guys spend all that money on porting, billet heads, case porting, reed, carbs, stroker cranks ect.. Why not have a new engine designed and built from the ground up without all the limitations you hint on.

If a B pipe works on 701 through 865+ then why wouldn't just one TNT do the job?

And has anyone ever confirmed performance increases with these? The most I ever heard personally was Paul L. say it hits a tiny bit harder on bottom end with a big motor behind it.

A stamped one will look nicer no doubt.

Welcome to the X.

That, in a nutshell, is what happened to PJS in the 80's.

After all the design is done, the bills are so high that you have to sell THOUSANDS of units to break even. If you don't, and you don't have the bankroll to oulive it, if it doesnt sell, then what? Ask the big three how that works out for you.

I have 35K in RE-designing and producing the 62t case to accept a 16MM crank.

It is way easier to be the "second" guy rather than the first. It would take at least DOUBLE that to design a case from the ground up. Just the case.

Hence the price of the ever so rare WDK 1200 and the ever so excellent team scream 865. Billet cylinders from a clean slate, correct?

Imagine a WDK 1200 with a giant TNT pipe!!!!

Why not just grab a 1000cc snowmobile motor complete and make bed plate?
The arctic cat m1000 motor with little porting makes 200hp?
It's fuel injected so throttle response is awsome?
All you need is to make inverted fuel system so it doesn't suck air while doing inverted tricks!
Have turbo version of a arctic cat 1000 with 1200cc big bore kit making over 300hp
