Yup it is...

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

That's stupid power. Nice job bro!

awesome! congrats!

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

Nice #'s

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.

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

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.

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,

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,

You changing kits?

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.

Yeah. To reach my power goals I was going to have to buy a new turbo, get the larger 3 inch charge piping, and possibly modify the downpipe to allow more flow. I was given a pretty incredible deal (sponsorship) through AAM, so I decided to make the switch to their kit. It was a pretty unique opportunity that came at a perfect time.

Nice. If I end up with a built motor I'll likely be disappointed I didn't go TT too. Of course there wasn't a TT option for a G when I took the plunge so nothing to really regret.

You might just have to pioneer another solution like you did with BP :driving:

I have no issues with the BP kit by any means. After some thought and number crunching, it was actually a tad bit cheaper to switch kits believe it or not. Modifying the downpipe would have been pretty expensive, the turbo, and the new charge pipes.... after adding all of that and what I could sell the BP kit for, it was cheaper to get the AAM kit.

As part of my contract, Ill be giving my review of the AAM kit, and my experiences with both kits and how they fare against each other. It won't be apples and apples because of the different power levels, but another bit of research to help other forum members in their searches.

AAM just called me and told me my baby made 680WHP on 93 octane pump gas!!! will post more after the weekend

Built motor ?
EcuTek Tune ?
I got's to know :tiphat:
Mines goin' to the Dyno down there ~ hopefully before years end ...

build motor, ecutek as well! good luck buddy!!!

How much boost? Did you get a torque number?

17 psi, no I didn't yet

Wow, e85 and about 6 more psi and you be looking 800 in the face. Nice numbers...

thanks man. Actually, they telling me if I decide to go E85, they think it will make 775-800WHP without increasing boost.

Awesome congrats!

Wow, I don't think so but I'm not a tuner and most everyone I know that has gone e85 added another 4 to 6 psi to achieve 100 more whp

Didn't phunk hit extra 100hp with his switch from 93 to e85 on his turbos at 12.5 psi?

Sent from my Nexus 6 using Tapatalk

I'm not sure and phunk is a rear cat...if what he did was easily reproducible then why hasn't it be done?

Sent from my SM-N910P using Tapatalk

That's awesome bro. Congrats.

Just saw on Facebook that someone hit 768whp on stock internals. Is that anyone on here? It's from T1 Race Development.

Of course it's a Fast Intentions kit!

This is going to be better than Star Wars lol. I got call bull$hit on that...

Anybody can number chase but it doesn't mean it'll hold together.

Right, and then there is that thing about how the dyno is set up. Not sure I know of many V8's that can hold up to that all stock motor.

any link/ info ?

Here is the link.

Has Tony confirmed this yet?

I haven't heard from him or Kevin...

I do think they can make over 700whp with a stage two kit pretty easily, and that stock internals could hold up for a run or two maybe, but time will tell on how long that engine will last after those pulls. There is a reason that even with built engines those serious dragsters rebuild and replace things after single run or two. That's just a lot of stress on the rods and pistons.

The owner of that car does realize that the motor can/will blow at any given time and is ready to build it when it does. I'm not impressed. Anyone can throw a car on the dyno and let it fly like that. Doesn't mean it will hold.

A rather "small" update to all the lists, if you do not see your name on this list or on the 1st page and have a finished FI build please post up your details.
