Yeah that would be insane. I think pairing with a centrifugal charger though would give you the nice peak top end of a CC but the ESC give you the low end of a PD best of both worlds.

An ESC and PD would be nuts but probably just spin tires and bend rods.

You might have space to run this instead of the 90degree elbow after the Y pipe before MAF housing.

Get a water pump wired to a tap a fuse in cabin fusebox lots of ign on ootions.

A small reservoir you can mount anywhere as long as its the highest point

And a water to air radiator in place of your air to air intercooler would be oretty easy to setup and provide good cooling even when cruising ad it sill have both air sources going through it.

Did a quick boost comparison between my last data log when I had single ESC and now with twin ESC

Rpm. Single. Twin
3k. 3.2psi. 4.3psi

Peak boost 4.2psi. @3200 7.1psi @3400

4k. 3.7psi. 5.9psi

5k. 3.2psi. 4.6psi

6k. 2.3psi. 3.4psi

7k. 1.3psi. 1.6psi

7.5k. 1.1psi. 1.3psi

Have a battery voltage at those rpm/psi lvls before/after?

What do you mean? Like phantom meter voltage?

Yeah, just curious if boost is falling off faster because of double draw. Or if you start WOT at 5500rpm instead of 3500rpm do you make more boost at 6000rpm?

Each charger has its own set of batteries. And i started with wot both at the same time. But boost kinda fell the same for both roughly 1psi by each 1000rpm up till 7k when it was almost the same but I think that doe to the engine sucking much more air. Either way on a single phantom peak boost was at 3200rpm 4.2psi on the twin set up I was still hitting 4.6psi at 5000rpm

Seems like a cool project but you seem to have the skills to install a more standard FI kit. SBD kits come to mind.

Lol yes I probably could've just installed an actual kit myself. Especially if it came with instructions. I pretty much built this whole setup from scratch aside from the phantoms kits themselves. But everything else I pretty much had to analyze every step beforehand everything seeing if a 4in filter would fit in the bumper to figuring out how mount the 2nd set of batteries.

So as we get closer to finalizing the tune on the twin phantoms I thought I'd post these Vdyno runs.
So here is a quick comparison (first image) between the 6th and 7th revisions of the tune. @steve99 is pretty happy with the tune. He thinks he can squeez out another another 5 ponies we just gotta make sure fuel trims are pretty stable when the turbskies are off, this way the tune is happy with and without boost. Anyways I'm pretty happy with it. I was really hoping to hit 250whp but how it is I love it cuz the tq feels amazing. This runs were done in 90-95 degree weather. So compared to my last vdyno from when I only had one phantom (second image) makes me believe I'll hit 250whp once winter comes around.

What were you making with just the single? Looks pretty damn good and a pretty cool setup

Single is the second image 229whp/206wtq but that run was done in 60 degree weather. That's why It doesn't seem like a huge bump in hp. But I'm sure if I do runs how the car is right now in 60 degree weather I think I'll see another 10hp

Yeah
I noticed with just the single ESC there is a major power increase with cooler temps. The difference between running at 90F and 50F is like the difference between 91 octane and E85.

are you talking difference in ambient temps pre blower, like stock MAF location on traditional ESC setup? or have you relocated the MAF to post blower and compared dyno runs or pull times between post 90F and 50F post blower temps?

ambient temps going into the blower will be much more of an impact to power compared to post blower temps.

Every 5.4F is about 1% less air density. but this would only apply to pre blower.
