However, I switched to it a few weeks ago kept it for sometime and logged. Had some knocks at no/low load (which can be normal) and can also be because the HPFP is not properly tuned, as the car even has the "hiccup" feels from time to time when using the OTS map. I spoke to TTFS at the time about it (noise & hiccups) and they said its normal, it just needs to be properly tuned, which was done on my custom map. |

Does TTFS have any input on the knocks? They’re going for pretty high boost in their tune. Have you ever done a dyno run just to see what relative numbers you’re putting down, which may also point to the custom tune? I’ll be going thru all this soon when I install a Dorch HPFP and begin running half 93/half E85 and do a custom tune with Halim. So, just throwing out questions. |

Yes it was dyno tuned, however, the numbers can be irrelevant as it was a Mustang Dyno and I don't think any M2 has been on that dyno. + I don't have a 'before' figures. Apart from the knocks, the car pulls really well. I'm satisfied with the performance but I'm worried about the knocks because I care equally about reliability. A negative point from the boost is the fast build-up of IATs. |

While a different IC will help with IATs, they’re not high enough in your logs to cause concern unless you have really crappy gas. Try some Boostane and see if that works better than the Liqui Moly. |

Just need to sort out this knock issue, might end up switching to another tuner. And yes I believe our fuel is crappy here, I get timing pulled as soon as IATs are close to 100F |

Goodness guys... if you need that much cooling for IATs, surely WMI is the way to go. I’m running CSF FMIC, but considering going down to a smaller FMIC to reduce turbo lag since going WMI.
WMI gives you cooling, octane and fueling, and really isn’t as difficult as is sounds. I’ve just done the M2C / M3 / M4 strut brace retrofit, and can say that our cars benefit a lot from more front end bracing. I really wouldn’t want to be removing bracing when there are other options out there. |

WMI doesn’t improve throttle response; its primary purpose is to reduce IATs. I thought that’s what this most recent discussion was about since you’re talking about FMIC upgrades which also improve IATs, at the cost of turbo lag (which isn’t fixed with a DV upgrade by the way). |

The DV+ and the Turbosmart Valve DO help throttle response, per other members reports. Most people also don’t report turbo lag with their intercooler choices. |

WMI could allow you to run more boost and make more power, OR... you could run the same boost and not need a larger FMIC. My point was simply that once you get to the point of needing the IAT cooling offered by huge FMICs that need bracing reduction in order to fit, it might be worth looking at WMI. I'm all for upgrading the pathetic stock FMIC, but the huge FMICs now being offered seem illogical IMHO. Quote:

And, I don’t know that switching from the Evo 2 Comp to the CSF is going to give me that much change in the IATs. And when running E30-45, that IAT difference won’t have much impact on power. It would be more about helping to keep the overall engine system cooler, which WMI would help some as long as I didn’t tune for additional power from the WMI. But, WMI would be a large amount of additional consumables for my needs at an open track day. So, if I could try the Evo 3 and if it fits and if it has a big impact, that’s preferable to me. That’s a lot of if’s, tho. Last edited by ZM2; 03-19-2020 at 01:18 PM.. |

I do think WMI isn't as big of a burden as people think. If you're only using it for cooling, you only need distilled water. As I think you know, I'm using the washer reservoir for my system and everything is mounted in the front of the car; nothing in the trunk. If you use it for the purpose you're suggesting, you don't even need a fail safe. You know that your tune is safe already, you're just using water injection to keep it safer still and avoid timing pull.

I’ll complete my HPFP and E45 mix/tune first to see how IATs are doing and then make a decision. |

My next mod will likely be upgraded turbo and / or HPFP, so your findings are interesting.
