Looks very nice, I think it makes a big difference in hp and torque.
Good job 👍

Hey FZ09 org

We are currently testing the new Gen 4 MT09 tracer with our variable intake stacks.

After some decent amount of testing we've come to some conclusions:

The stacks really start working when you make the TPS map leaner in the higher RPMS 7k-10.5k rpms, it sounds strange but it is actually how it should work.

We also found out that the upper air lid box is restricting the air flow to the stacks. The lower part were the ECU is mounted cuts of some air but the most restrcition in airflow comes from the three uneaven intake pipes going into the airbox.
We removed the them and the lid to see what happens, and we gained another 4hp.

We modified the air box even further, this week we are also testing the DNA high performance filter STAGE 2 KIT.

The stacks on the dyno

when the gen 4 ones are finished if you want an independent tester ill volunteer my time

Gen1 gen2 gen3 it’s been proven, it’s working and with a flash and the stacks I have 126 on the wheel…..

I'd still really like to see an independent 3rd party before and after dyno.

Come on guys, for the third time these guys making stacks for the mt 09, 1/2/3th it makes no difference only the model of the airbox ???
So why always be sceptical?

 

[psycoreefer]

I'm not more sceptical now than I was for the Gen1 or Gen2 or Gen3 releases. If you look back through the thread I've been saying the whole time that I'd love to see some 3rd party DATA. A few customers have posted that they are happy, but that isn't enough to convince me to put down $1300 + shipping. Buyers or Customers are always going to be more likely to say they are happy because they spent their own dollars and its hard to admit you spent money on something that isn't as great as you hoped.

Specifically I'd really like to see 2 sets of numbers:
First - Bone stock bike without variable stacks vs Same bike, same day with stacks and the VP tune
Second - Bike with whatever mods VP thinks gives them the most improvement and vcyclenut tune vs Same Bike, same day, only change is the VP Tune and Stacks.

From whats been posted so far it looks like someone could pick up around 5 HP, and I could easily see that being the result of a different/better tune rather than the result of adding the variable stacks.
I personaly am not willing to spend $1300 based on 'maybe' getting 5HP when these don't really provide any other benefit, and I bet a lot of other folks on the forum are in the same boat as me. Some folks are 'power at any price' and maybe that is the only group VP wants to sell to, but seems like if there really is a significant gain to be had here they could open up a lot more market by putting some trusted 3rd party testing behind their product. I'm not saying this is without risk to VP, but if they are as confident as they claim to be in the improvment, then the cost is minimal. Vcyclnut who is also a business owner and a trusted memeber of the forum has offered to test (for free) and report his findings, IMHO VP would be silly not to take him up on that offer.

The stacks are working no doubt about that I had a Woolwich flash with 122 bhp,same day same bike same dyno , just stacks 126 bhp and 4,5 nm over the whole band

so you gained 4HP and 3lb-ft for $1300. Who did your 'before' flash? You say Woolich but (unless I misunderstand) they sell the flashing 'tools' and don't actually do any tuning themselves - whoever applied the flash created the throttle and fuel maps you were using.
How much did you gain when you applied the original ECU flash?

You are totally wrong informed about these guys.
They used Woolich software for tuning equipment, not a flash without a run on the dyno, that’s a amateur flash and hoped you aimed good, takes about 3/4 hours on the dyno for perfect and max performance so yes 1300 for the set and flash.

Whats been going on with the stacks for the new mt09
