Dark Horse Track issue（Temporary loss of power）

[N1T3MRE]

There is a video on YT with a Dark horse doing laps at Phillip Island. Journalist said same thing, believe it was turn 4 and between 50 and 75% tank and it would cough.......Phillip Island is predominantly long mid to high speed corners.



Planning on tracking car soon at new track near Townsville North Queensland, and will report back....taking a 25 litre jerry can with me to track just in case it does need to be above a certain level.

Misha Charoudin was getting fuel starvation on the Zaandvort circuit after they did some suspension mods and put sticky track day rubber on. He hasn't mentioned the problem on the Nordschliefe though.
The tank needs baffleing.

@KPM Fuel Systems
congratulations on the achievement. i have been following this fuel starvation issue from time to time. sad to see this issue with a car marketed as "most track capable". i have one and love it but would love to never see this fuel shortcoming. whats the secret sauce here? more development in the crossover tube setup? i searched for more of a dual module setup but will yours completely prevent this left turn starvation?

Hi
I will try and answer with a cut and paste I did on another thread.


The KPM fuel module is a direct replacement to the OE module and fitted exactly in the same position on the LH side of the fuel tank as OE.
Internally there is a tube connected to the fuel module pot that runs across to the r/h side of the saddle tank. The tube "sucks" the fuel across from the rh side to the lh side continuously. This ensures that the fuel module pot remains full of fuel and cascading at all times.
It does this by utilizing "venturi jets" that work by "sucking" fuel from the bottom of the tank into the module pot , keeping it full.
The OE fuel module has 2 venturi jets. One to keep the pot full by "sucking" fuel from the bottom of the L/H side of the saddle tank and the other to suck fuel across from the R/H side of the saddle tank.
This is fine until the r/h side of the tank becomes empty. This eliminates fuel being sucked by one of the venturi jets, therefore the pot staying full now relies heavily on the 1 venturi jet.
Again this is fine until the vehicle starts to corner heavily, sloshing the fuel around the l/h side of the saddle tank. The 1 venturi jet now struggles to pick up enough fuel to keep the pot full while fuel is passing across it while sloshing.This causes intermittent fuel delivery and surging.
All KPM fuel modules are designed with 4 venturi jets. Regardless of the quanity of fuel on either side of the saddle tank, the venturi jets have more than ample ability to keep the pot fuel even under severe high speed cornerring.
Hope this makes sense.
I have attached a link to one of our tech videos, that touches on a visual explanation of how the KPM fuel module and venturi jet system works.

tire temp is a hidden function, adjusted by software similar to forscan

Love that display, is there a way to turn on those options on my 2025 dark horse? Tire temp ! Awesome
