AFRs are still a bit scary but I'm thinking with more fuel i should be making more power.

Let me know if you have any questions. I'm planning to hit the dyno again once i get my 1.5 dump pack and will likely ask Shiv for an e-tune to clean-up my AFRs.

Results look right in line with the TQ250 with standard dump pack.

This is exactly why the 1.5 dump addition exists. It helps that fall off on the top. You should hit over 210 just by adding the 1.5 conversion. As shiv said the other day, the AFR spike down low could very well be contamination.

Thanks for posting all the results and your thoughts

In the pics fenton posted, there appear to be 4 batteries on the tray. Is there a different tray to fit the 5th battery?

The 2 smaller 9 AH batteries are placed on their side with the bottom of each towards each other. By doing this the batteries are almost the same size as 1 of the regular dump pack batteries.

Edit finding or making a picture really quickly.

Hey guys. The picture that i posted with the phantom conversion adapter has two batteries butted up against each other.

All 5 batteries fit in the new battery tray.

Yeah using this picture you can see that the two smaller batteries are on their sides. These two batteries are taped together. And the plastic piece on top puts them in series.

Underneath the Phantom sticker?

It is a noticeable difference. It just keeps pulling. Both Bu-tang and Rob noticed a difference in my car.

Shiv noticed a difference as well when he did his dual dump conversion.

BTW, thanks to everyone for being so helpful and not flaming obvious ignorance.

This is the first time I've ever done any significant engine mods to a car, so...

No worries it's what we do. Hopefully between Fenton and myself it was cleared up.

Btw- I highly recommend the 1.5 pack.

First things first, ESC vs. stock + stock map (both with front pipe/CBE/intake filter)


LOVE the 50% torque gain in the dip


Hate the drop off towards 7K rpm, really rewards you for keeping it between 3-5K

u
The Phantom ESC was hitting about 4.5psi peak boost, then dropping to 0.5-1psi higher in the rpm range.

Next up i tested SPM (Super Pursuit Mode turns off throttle switch) vs. stock to see if I'd actually gain/lose anything with drag reduction only. I did.

ESC Super Pursuit Mode (red) vs. stock + stock map (both with front pipe/CBE/intake filter)
Was surprised to see peak numbers were pretty much the exact same with SPM actually producing less low end torque until 4K.



Next i wanted to see how the ESC would perform with an aftermarket intake filter

ESC vs. ESC w/K&N Filter (both with front pipe/CBE)
Nice gains! almost 10hp and 10tq higher in the rpm range.


Although my AFRs started to get a bit scary with the filter. Although this was with the dynojet exhaust sniffer, not OFT data logging.

What is stock map ? Shiv's or the factory map?

I considered just going single dump pack and getting an OFH sooner... but I think I'll go 1.5.

Any thoughts on whether the gains are better/worse with 1.5 and no OFH vs. 1.0 and OFH?

Got it. Yea - I looked at the pic several times and only saw 4 batteries... LOL.

I see now that the thing with the sticker on it is actually connected to the side (actually the top) of the smaller batteries.

Loaded question. I would recommend both. I guess the person that would be best to answer this @nlowell when he gets the 1.5 pack or he and I can do a side by side drag race again. Since he has the ofh and I have the 1.5 pack currently.
