hi

i did some nice dyno runs last week.
for me the first time with the BMS Controller for the PI.
before I had the AIC controller, which was by far not so good.

so what to say....it works very very good

.
at the end the small 550cc injectors maxed out, and we had to stop at map6 which results in 968hp. time for bigger injectors

That's awesome stuff! nearly a thousand wheel and under 30 psi too. Have you done head work or stock head?

How much psi and timing for 970 HP with the 6870? Which A/R do you use? seems to fall on its face in high rpms

Not to split hairs, but images say 968ps, which google says is 954.xx. Still amazing numbers.

Cool idea building it into the AC compressor housing. Quite a lot of torque, what's done to the trans?

Some secret upgrades inside ;-)
Last year I had some probs at 1100nm.
Hope this year it will hold the power.

Change out that turbine housing for a larger a/r and I bet you see at least 30 more hp.
