Contour Enthusiasts Group Archives Forums General Dyno and Drag Dyno of 3.0L Duratec Twin Turbo

That's pretty good though I have to point out that at 6psi you are almost identical to my 3L single turbo at 6psi. I set down 300 wHP that day then backed it up with abouty 8 more runs ranging from 295-300 wHP at that same boost level throughout the day.

I am going to be dynoing a 10 and a 12 psi run the next time I get to the dyno but it will be with improved header pipes this time and different tuning software, the SCT Racer package.

What car is this in, a Noble?
What size fuel pump? I ran the stock pump at 300 HP and it was just barely enough fuel then switched to a walbro 255lph pump when I latered dyno'd 326 wHP on around 8.5psi.
I would say it is probably a fuel pump issue and/or injectors, or MAF flow capacity.

What does the stock MAF transfer function look like BTW? What size injectors.
If you give me a little information I can probably help you out.
