Forced Induction Finished Builds

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 actuators would need to change to be able to get more PSI. But because of the cramped spaces the motor would have to be dropped to change the actuators out. Because of the this, *IF* that ever happens I'm sure the turbos would probably be changed as well.

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.

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.

I'm in the same situation ... what price did they give you for the upgrade?
When the car was shipped down there they didn't have that option - or they just didn't mention it to me.
Thanks,

Thanks for your reply...
Yes ... torque falls off [affecting the rate of acceleration] when HP takes over.
Just realized that you have a G35 ... different motor than the 370.

I have been down to AAM to 'visit' my car ... and there is no room to fiddle around in that cramped motor compartment at all!
They would have to pull the motor to do any work on the Turbos.
I did speak with them and they are aware of my concerns regarding the/my need for power up top since I do plan to run the 1/4 with it.
I am running 9.5:1 CR with 1300 Injectors so I'll be needing a lot of air to keep up.
The stock Turbo's are in the car and we are waiting on a few more parts to come in before the Dyno Day arrives to see how it all works together before finalizing the decision to change the Turbos.
Probably will speak with them again regarding all this beforehand to see what is involved cost wise to do this.
In the meantime I will still be fishing for more info!
Thanks,

LMAO with that much power who cares

...nice build man!!!!

zguynate · 12-09-2015, 02:43 PM

As far as I know, Alterception is the first and only person who has purchased the upgrade so far. My knowledge on it is very limited, but I'm not sure if it is a direct turbo swap, or if something inside the turbo is swapped out, still using the original housing.
