I’m so tempted to just full send and buy it now, along with the Turbosmart and inlet. I just can’t see how the Wagner Evo 3 would be any better than a bigger denser core. And it’s $800 more expensive.
This quarantine has me saving, but...now I’m getting cold feet! |

And, I have data from one of our pioneering forum members who figured out how to fit this beast to their Stage 2 M2 that shows IAT temp drops in gears 3-4, and only a couple degree rise in 5-6 on 90-95F days. That’s better than the data that CSF, VRSF, or any of the other IC manufacturers have posted. I wasn’t going to post anything until I get mine on in a cpl weeks and get some data, so we’ll see! I’m hopeful that this has a big impact on engine temps by pushing much cooler air into the inlet and across the radiator vs the Evo2 Comp. I won’t have on track data for a cpl months, but will get some good street pull data beforehand. |

Lies about tube and fin construction (it’s cheaper and less dense) And literally the only thing positive I believe is the it has less pressure loss due to less density. I’ll wait for the logs, but I’m not a fan of Wagner as a brand at all |

You’re not reading the data correctly and in the way that really matters. In VRSF’s own chart it shows about a 5F rise in IAT in 3-4 on a 75F day. Plus, their pull is 2-3-4. Frankly, that’s lame. 4-5-6 creates much more heat than 2-3-4. Their data does not bode well for hot track days when you’re never in 2nd, hardly in 3rd, and mostly in 4-5-6. Whereas, I have data from the Evo3 on 90-95F days showing IAT drop in 3, stable in 4, and a cpl degree increase in 5-6. This is even with hard braking events between pulls, something none of these IC manufactures ever show! I’m not brand faithful, I’m solution faithful. From what I’ve seen the VRSF Race won’t hold up compared to the Evo3, but like I said bolt one up and let’s compare some logs! I could care less if an IC is bar/plate, tube/fin, made of wood, or is a time machine. Whatever cools best without other major sacrifices is what I’m going for. I’m just happy that a fellow forum member had the balls to get one, fit it to his M2, and collect some great data! Last edited by ZM2; 05-22-2020 at 11:12 PM.. |

But compared to how you were arguing a month ago that hitting 140* in every gear was ok, it seems that you have changed your tune. The temp increase is not linear, and it doesn’t mean it will increase by x amount over X time. Quote:

All false. I prefer to review the data myself if you don’t mind, I just don’t trust you to be unbiased. |

The Evo3 data I have is not mine, I was helping a forum member. It’s his call to post. I’ll post my own soon. Bring your data, and then we’ll see what’s what. |

I have no idea WHY your so stuck on this WE3, (which, 2 months ago you had already admitted that you wanted to buy it over other proven products- because reasons) but to each their own. I’m not going to just let you fabricate nonsense and confuse new members. |

Quit polluting this thread until you have your own data to contribute. Come with your own numbers to contribute for everyone else, not a bunch of behind the keyboard analysis. I’ve given a ton of real world data from trying and logging. Show us the VRSF or something else is better by putting it on your car! None of the IC manu’s are providing heads up track data for comparison. It’s up to us to vet. Last edited by ZM2; 05-23-2020 at 12:05 AM.. |

And, the fact that it bolts to the bumper makes it a much more attractive option to me for the track, vs other heavier FMIC’s that just kind of sit there upfront with a couple bolts. We’re doing several other things (Pure inlet, Turbosmart BOV, Dorch HPFP, NGK plugs, aFe filter, and 300V oil), so my mechanic is taking his time and I’m hoping it will all be buttoned up tomorrow! |

Thanks again for your install notes, and I'll post up my data in your thread and here to see how the reduction in IATs impacts engine temps. |

Did you ever solve you high coolant temps? Because I was thinking about your situation recently compared to other m2 owners (reasonably capable track drivers) who are on the stock radiator with a tune and turbo upgrade and had no real heat issues, and I wondered how did you bleed your CSF radiator? Did you bleed it with the standard low beams on, max heater temp, and pedal to the floor for a couple of seconds until the coolant pump activated? Or did you bleed with a pneumatic bleeder that bmw recommends. Because if you did the former then you may have bubbles trapped in the CSF radiator which may have inhibited the full potential of the CSF radiator. If not then I suppose the CSF radiator is really not up to the task of cooling a modded m2, and the race spec version is probably needed. I'm just bringing this up because I wanted to do a coolant bleed myself this summer and when I looked through the TIS I noticed a pneumatic vacumn bleeder was required and due to the pandemic these things are hard to get right now locally so I am postponing this whole coolant bleeding thing until next year.

That’s a good question. I’ve had multiple shops do the coolant flushes. I’ll ask my last shop how they did it.
I will say my latest tune, half E85, Evo3, and distilled water + wetter seems to be helping. I still hit 250F coolant but it took 13 back to back 3-4, 3-4-5 pulls with hard braking in between on a 95F day to get it there. It seemed like the ECU was keeping it under control, whereas before I could blow right past the first temp warning. Last edited by ZM2; 08-08-2020 at 07:09 AM.. |
