Was there a power loss or insufficient increase in power/torque for the price point of an aftermarket front pipe? |

If you add a front pipe to both setups, the Ace still makes more power. It was most to just illustrate the different setups that are possible with a similar budget, utilizing a less expensive header and flex fuel. Both of the illustrated examples cost about $2000 (750 + 600 + 750, vs 1530 + 450)

Please let me know if I'm not making sense; this isn't the normal type of discussion I usually post online. It's usually more geared toward engineers.

It's perfectly clear and easily understandable. It's nice to have you sharing important informations like this. That's the kind of posts I hope (and fail) to find most of the time.

The disclaimer is they're using an off the shelf Stage 2 tune from Delicious Tuning meant for a different header. In other words, their dynos showed what would happen with the ACE header when using a tune meant for a different header.

Thanks David. I was aware of them using a tune for a different header. Just for clarity, can you confirm that the loss doesn't exist with a proper tune? Edit, I just reread the first post. Nevermind. |

We actually thought we were going to get some dip in power. To our surprise, the power is absolutely linear with no dips. The front pipe added a substantial amount of power in the NA configuration which was actually more of a surprise to us since generally front pipes yield a mild gain. Response is substantial and power is very different from the other systems we've played with.

That's awesome. Thanks. Any chance you have a dyno showing this, please? Also, are you guys moving toward offering e tunes for this setup? Or do you have any specific tuners you would recommend? |

with E85 we see virtually same gains from cheap headers like these (that look like they were designed on Friday afternoon over a few beers and welded by people who have never seen a welder before) or high end headers http://www.ebay.com.au/itm/TOYOTA-86...-/151383079811 the one thing we have here is good E85 (our petrol is crap worse than your 91) Guaranteed E85 at 85% ethanol and 107 octane available at the pump. |

Note that the "dip" is a phantom dip, from additional tuning done to maximize the potential of the chambered front pipe. We can place the dip precisely within the 2500-4500 RPM window, by altering ramp time; in other words, it is an artifact, and not actually there. |

Or in other words normal customers with normal front pipes with normal tunes for this header wishing linear delivery won't have dip in low rpm-s more common @ daily driving / cruising.
I still wonder how Ace managed to got all three checkboxes checked, top power, middle rpm power, dip elimination, when most of other had to choose between. Especially Nameless, whose EL also has long runner lengths, just shaped different way. |
