There are zero tuners around here that I would trust with this car. Will base maps be available for someone like me? If so, how far off from these would they be?
That 8 psi map is spot on what I'd like but I can only get 91 octane. Awesome work guys! |

Very promising! Have you guys ween any exhaust limitations for the power levels you're on by now? AFAIK you have full 2,5" piping with a Hi-Flow Cat in the frontpipe, right? ( same as my current setup) I wonder when would one benefit from going wider piping, as it is considered that the wider =the better for turbo applications What EGT you see on top and what's the critical figures you should be careful of? |

Truth be told, the conservative and cautious side of me would have anyone going past Stg 1 to get upgraded injectors and a fuel pump. This applies to both MT and AT models. This is especially true for the AT models because of the drivetrain loss; the engine has to work harder to get to the same power levels as their MT counterparts. I am however, not a big fan of the DW 265s that are currently out there and truth be told, is probably the only factor holding me back on pushing forward with more boost, and aggression to boot. At some point, the OE sensors are also going to hit a physical limit, and the discussion of what "works" as opposed to what's "professionally correct" is going to come into the picture, and that's a whole nuther' can of worms altogether. But it's coming to be sure. For now, since everyone has been harping on this "300whp" number, AVO figured it was time to share that portion of the development to show what this setup is capable of, and understand that the AVO car itself has been running this way for some time now as well. On a side note, I'm not sure if any of the FI contenders have done longevity testing, in that the AVO car has already traveled some 7000 miles across various states with a different diet of fuel ranging from 91 - 93 and still has no issues as of today when I saw it, and this after six (6) Gymkhana sessions.

Bob- Great result. Can you confirm if the fuel system is return-less and if yes, whether or not any re-calibration is required in the tables when upgrading fuel pump?

@Drift-Office
your detailed approach is the reason why I'm with you, AVO mafia ) I've prepared for 10+psi by purchasing 700cc injectors and HKS LA Clutch only thing which puzzles me as you is the fuel pump pls advise some trustful item to swap the stock pump with ease I know Ross is doing some research on that, but has anyone the proper solution yet to feed this beast? walbro? avo? else? |

AEM has a high flow in tank fuel pump (presumably a Denso unit made to AEM specs) that might be a good solution,

Why are you suggesting this? I'm running 10psi so far on oe injection and pump,sure its a whole different can of worms,but are you finding fuel delivery to be an issue past 8psi? just asking you to clarify the quoted statement, thx, perhaps you know something I have yet to learn, and can save myself some learning curve?

@ MSTiFK8 ~ DW pumps are drop in, but having had personal experience with their 300lph walbro replacements and injectors, I'm more inclined to stay away. Again, that's just IMHO and my direct experience. I will be testing out the DW pump(s) and another brand of injectors on the AVO and my personal car, and pending the results of that, we'll have to see. Until then, I won't be making any specific brand recommendations as of yet. Regards, Bob @ Drift-Office, LLC |

Took alittle work to fit in the stock hanger but that might be the case with the other pumps too (AEM is all i have experience with though..) It also needed a rewire and relay after ~370whp on my car (e85 and no DI).

I think at issue here is all the different measurement systems being used to express the power of the various kits. If we were to take the general view that a hub dyno will show about 10-15% more power than, say, Drift Office's dyno, then conservatively, in relation to the hub dyno plots, we've been running in the 325whp range at 10psi, and the 298whp range at 8psi. Also, whp changes purely on where the torque is made, and may not be based on how much peak torque there is. |

Convention would dictate that if commanded & target AFRs meet, you've got enough. However, this being a combination DI fuel system, convention doesn't apply here as much and you're right, it's a whole different can of worms that doesn't belong here. Cheers! Bob @ Drift-Office, LLC |
