Turbo Dynamics Canada Dyno results

Thanks TD, its all good info, even if nobody agree's what the real baseline is from one dyno to the other, the improvement, and maintaining the HP's through the RPM is the key.. and you seem to be on top of that..keep us informed on your tests.. and yes, the gutting out of stock muffler is pretty much the best way to go in Quebec, but in the off trail crowd, the free flow is the ticket...

Hey rash, we actually don't gut the muffler. We change the piping to 2.5 and we remove a tube and increase the flow. We do keep the sound cancellation of the muffler. Gutting it would make it pretty loud !

Steve cant help himself, his excitement gets in the way of his typing on the key board. LOL
Right buddy??

Hey what the ??? don't tell them my real name now I have to go into the sledder protection plan

Now here's where many of you go wrong. You read peak numbers, the don't mean too much, especially on a track dyno. Clutching can cause peaks to be worse and make it read higher than it should.

For example the stock tune, has a pretty strong peak, but falls off in HP through the run. While the Ecotrail and muffler run maintains HP through the run.
So not only do we have a a 23 peak Track HP gain/46 peak engine HP (or whatever conversion you believe in)/21.6% peak HP gain in power from just a few psi and a muffler.
But that is just the peak. We gained 25 track HP at 90 MPH and 30 track HP at 100mph vs stock.
Gains climb as the run goes through because that's when the clutches stabilize and show the most accurate track HP.

The true gain is much greater than you guys give it credit for. The average gain through the powerband is 26 track HP not 23... and the average gain in power is 25%.

The % of gain is absolutely not constestable. Use that to calculate what you believe is the real baseline HP and multiply by 1.25 to get the average HP gain at the track (real gain) through the run
As for what the real final crank HP is, that will be debated forever.

You refer to peak numbers, even if it dont mean much ??
You use the peak number to tell your customers; if you buy our kit you will have 258 hp.

Alot of people, maybe buying their first turbo-sled, just looking which company will give most hp, and buying from them.

Other company, maybe starting at 185 hp, and then adding 40, will have 225 hp at top.

But in many customers head, your company have delivered over 30 hp more, and thinking you give most hp for the money, even if they are equal.

I have run a turbo sled in many years, and learned alot about yamaha and turbo-power.

So what is the stock boost (psi) on the Sidewinder?

You are not reading my post then.
I'm saying dont look at just the peak but average hp through the run that's where our tunes excel the most.

I also tell guys to always compare against the baseline on the same dyno.
Check the % of gains.

Dyno that read lower will not reach 258hp. We have an average % gain of around 24 to 25 % through the run. Peak gain id 21.6%... But average gain is more important.

Also our yamaha was fully inspected and we had found a 0.8 psi boost leak.
Had we not found it. We would have not dynoed as high for our baseline hp.

The tbs have very small lips and there are many connections. Pretty easy to get a loose clamp or a boot not fully on.

So what is the stock boost (psi) on the Sidewinder?

The first runs we did we had 9.2 psi
After the boost leak fixed we had 9.8 to 9.9 psi once rpm stabilized. Boost varies a little by rpm...

 

[Turbo Dynamics]

The td turboforce leans out the stock map to 12.7 to 13.0 making more power than than td super quiet also raises boost even more as the ecu is struggling to keep boost at the factory 9.9 psi level.

LMAO.. whatever your real name is Gomer.

So if your super quiet muffler is on the lean side, you will have to sell it with a fuel map and that will go again the waranty !

We have a map we call Aftermarket ready that just enrich the stock map. No change to boost control and still all the factory safeties. Also we have a few tricks to enrich the stock map without touching the ECU. We will test that next week.

Ok that's good news can t wait, I will have many guys here in Saguenay waithing for and aftermarket exhaust that is good for the trails (noise), safe, with proper instruction for clutching.

Our td stock modified exhaust stage is close to being ready we have extensive experience working with factory noise cancellation style exhaust and we doubled the flow of the factory exhaust.
We believe it will still be very quiet and will look stock!

We used a similar design as our existing 1100 turbo stock modified muffler they are very close.

Good! Now what will be the hp gain?

Should be in between turbo force and stock.
