bouchard & coga ?

I am not sure about the length, maybe about 250 m. Grade about 7 %. They don't take time, first in finish line goes to next round.

 

A drag race prepped M11 would give those piston cracking liner scoring Cats a run of their life. And without cheating, fuel only 1600 hp.

 

I heard some of those guys stack 3 pittsburgh boxes...

 

I don't think those guys are running pitts boxes. Have you heard them idle? They got someone that can open the ecm up and play with everything. Definitely not stock timing

 

Some run boxes but coga and buchard dont, just alot of fuel and aggressive timing, black stallion even had a sticker talking crap about pitts power.

 

A significant person from PP had told me at the MATS last year that Coga had used 2 power boxes togther.The guys at Greatlakes had also claimed doing the engine for that truck.....who knows right! Who ever did it,it made for some good videos and pictures.

 

PP has done some work for those trucks. The idle is coming from the oversized injectors.........you start flowing that much fuel through them.......the ECM can't hold a steady idle.

 

Why stack multiple boxes? They can program those boxes to keep the injectors open as long as you want, theres just a limit how long is beneficial and that is when piston is down enough and the pressure and temperature is too low to keep fuel burning. And also when injector cam is not lifting anymore. I think normal comp box setting +300 hp from stock engine is enough for those engines too.

 

The big fuel gain is from extrude honing the injectors
