I'm not doing that track night event but I have been thinking about trying an SCCA event. I've only done NASA events, but that's just because the people that got me into tracking the car were NASA folks.

I'm a M235i, so fitment to me isn't the exact same for you - but people have installed both the ER and Evo3 on these (M2) cars, so it can be done.

I've only run the SCCA event, and I loved it, but I won't be making the this tracknight event. I've only heard good things about NASA, I may give it a shot sometime soon.

Do you have a video of the install? We always get questions regarding fitment of the larger intercooler on the M2 and M235

I'll try to do a video when I get VRSF Race.

last week i ordered a ftp chargepipe and CSF intercooler for my OG M2.
At the moment i'm running BM3 stage 2 with a catless downpipe so i wonder what to expect from powergain from the intercooler.

[vrooooom]

If you’re on stock chargepipe, I would strongly recommend you don’t run BM3 until the ftp is installed.

I was just on stage 1 93 oct for a day or two and it blew in 2 locations. I’m assuming stage 2 runs even higher boost. So anyone who knows for sure can correct this. Save yourself any possible damage and headache and hold off on the BM3. My car has very low mileage FYI.

I have read about this blowing chargepipe a million times and ignored it. I should have expected it when it happened. Lesson learned. Mine happened just 500m away from my house so i immediately took it back to the garage. If it had happened 2 hrs away, would have been a headache. I hope it doesn’t happen to you.

I also got the CSF and a downpipe. still waiting for it.

[Rub1con76]

Tnx for your tip, but i really can say that i don't push my car until the parts are not installed.
I don't register for car events or driftday until my parts arrive

Stock tune on 93 pump gas with new MAD 5” intercooler. Single gear pull in 3rd gear as I don’t have many places locally to run past 90mph. 75F ambient. IAT climbs from 90F to 103F from ~3k to ~6500k RPM. Maxes out at 106F a couple seconds after getting off throttle. Off the gas for a several seconds, IAT drops back to 96F.

Just flashed to bootmod3 Stage 1 93 this afternoon so will try to get a log of that sometime as well.

Thank you for sharing, looking forward to the stage 1 logs.

I’ve been pleasantly surprised by stage 1... just monstrous torque. Just spent about a half hour blasting around town in second gear, full throttle pulls to 60 or so probably a dozen times, and came home with the same IAT I left with. Once I get a chance to get to an on-ramp I’ll share more. So far so good.

That's seems very…. Not good.

Reserving judgment until I can run a few more logs, but as of now, not crazy impressive. I didn’t get a chance to log the stock intercooler but it would seem it rises 32 degrees on just a third gear pull per the below. Not sure what others have seen in that regard. If true, it’s still a significant improvement over stock and for my spirited driving only/trackless purposes may be sufficient. The most difficult thing to tell is how much less (or more) it heatsoaks at idle compared to its competitors. That is as much of a factor for me as the IAT delta at WOT, since it’s my daily driver.

it went from 88 to 102 on WOT, that's 14, not 32 ... It's decent but then again you are on stock boost.

Let's see a log on map 1, if it stays within that range you're good for a daily driver.

In order to compare it to other intercoolers, you need to also compare weight, pressure airdrop, and recovery. As the higher the fin density the better the cooling (the only thing you are measuring) but the worse the other factors (which you are not measuring).


As mentioned above, these are all assumptions without a datalog. Post one with map 1 , measure the rise on WOT and we will know how it performs for a daily driver

I meant it would seem the stock IC rises 32 degrees, not the MAD. The MAD had a delta of about 13 degrees through the pull, so if that number is accurate it’s still a solid improvement. And yes, totally agree with your second point- kind of what I was getting at with my heatsoak comment. There’s more to it than a flat IAT graph at WOT. I am very rarely going to rip the car more than 2-3 pulls... just want to stay below the 120F mark where timing seems to pull. If I can achieve that the results will be satisfactory.

Generally mine would see lower IAT or no change after just one 3rd gear pull.

If you are using a larger intercooler or one with a better core density it's normal for the IAT to be better. But on the other hand, it's going to weigh more, has more of a turbo lag, and takes more time to recover.

Not saying one is better than the other, but for a daily driver, a 14-degree increase is decent and won't make any difference. Still a big improvement over stock

[Dasnub]

MAD 5” intercooler and chargepipe, Stage 1 93 Bootmod3 logs in Sport+. 69F ambient. IATs still rise similarly to stock tune logs I posted but recovery time is excellent. I ran the logs a bit longer so people can see the return back to starting IAT. Generally temps were back down to original IATs within a minute or so on the freeway and about 10 degrees over ambient.

Overall I think it’s a solid choice for a stage 1 DD in a cool to moderate climate. I am satisfied with the results given my driving style and climate. The 20ish degree rise in IATs during the pull is probably not what you want if it’s consistently 90+ degrees outside. Same thing if you’re running on track- the increasing temps on throttle are probably more than you’d want. However, If you’re juicing it every couple minutes through a gear or two, it brings you back to an almost even starting point after a short period. I’m not sure what the recovery looks like on larger ICs or those with higher fin density, but my guess based on sheer physics is that the MAD unit is probably recovering more quickly than them, making it a better DD option. Additional lag over the stock IC is not noticeable.

Run 4
https://www.bootmod3.net/log?id=60b7...90c60fd5b8e4cd

IAT rises from 80 to 103. Recovers to 91 within seconds. Recovers to 80 within a minute.

[mike@x-ph.com]

Thank you for taking the time to post your logs, it looks like a 50-60% improvement over stock without turbo lag

In my opinion, it's a good choice for stage 1 drivers.

More advanced applications will need a larger intercooler

[Dasnub]

If anyone is willing to take a look at how the car is performing overall on the stage 1 tune, it would be much appreciated. I believe the only run with DSC OFF was the 4th one.

Nice. Seems quite similar to what I see with my Wagner EVO Comp I and Dinantronics Stage 2 and catted DP.

I'll review in a bit - but you can post them on the F30 side and thejeremyman9 will typically review them, he's a wealth of knowledge.
