Who did your work? I'm in the Denver area.

1st Dyno Run - Stillen SC

2010 Manual Roadster
Stillen SC setup
Stillen Base Tune

This was on a Dynojet with Load Controller (?)

Not quite what I was expecting to hit, but I imagine it would be higher if I were to get it Dyno tuned in the future.

*Had the Coolant Reservoir 90-'arm' on the Reservoir Cap break during one of the runs as well :-/

That's got to be E85!

Yup it is...

My final E85 tune, I can't get anymore than 21 PSI out of the Borgwarner EFR6758s with the medium actuators.

Have you maxed out the turbos or would you need to change the actuators? I'm new to the internally gated turbos.

( Click to show/hide )

Is your motor built and 11.1 CR ???
I notice that the power/torque starts to fall off at 5000 RPM.

Is this the AAM kit ???
They use the EFR6758 but with the 0.64 housings in their kit...
These housings offer a more snappy response in the low/medium end [less turbo lag] but power drops off up top.
The 6758's are also available with 0.80 AR and 0.85 AR housings that give you more power at the top [better for racing] but you do get more turbo lag.

Mine's down there for the TT install and this is something I need to seriously consider at this point.
Thanks,

The motor is built with 10:1 compression. I always thought that torque starts to fall off when HP takes over - is this not true?

I have the AAM kit with the EFR6758s in their default configuration.

LMAO with that much power who cares :stirthepot:...nice build man!!!!

Yes this I have the AAM kit with the EFR6758s in their default configuration.

Good to know. Ill be shooting for 700whp and want to make sure that I won't be choked out right under 700 lol. The turbo upgrade for the AAM kit def isn't cheap. Im still on the fence about it, but I'm leaning towards no upgrade and just maxing out the regular turbos.
