We’re all impatiently waiting Shiv.

Any luck with logs?

I was at The Ridge again this weekend and the weather got a little warm 77-80°F ambient, and track surface was likely hotter. On the front straight, I was now in the IAT range of 125°F to 162°F - WOT, shifts close to 7K rpm, get onto the straight in 3rd gear and am in 5th before braking zone (131-134mph). Stock tune, stock IC - didn't feel any power drop and top speeds were the same as the last time I was here in much cooler temps.

Actually yes, but I stopped logging when my car had to go in for maintenance (I don't have to commute, so I don't have to drive)

But you won't "feel" timing pull, your car is just slower. but at 125-162 you're absolutely pulling timing.

I have a BMW track meet tonight, so I should be able to get some logging done as well.

You're right. A buddy with a CSF intercooler and Fabspeed hi-flow downpipe, on stock tune, was running about 3mph more on the front straight and I believe his peak IATs were under 110.

If life doesn't get in the way, I'll try and install the ER unit this weekend.

As requested - 3rd Gear pull
https://datazap.me/u/amuroray/log-16...g=0&data=15-24

I'm about to take a quick run, I'll do another 3rd gear run. I don't feel safe doing a 4th gear run yet.

Toasty!

[AmuroRay]

I got a really good 3rd gear run and It didn't log. I'll give it another go tonight when there is less traffic. I found a really good back road that will give me a chance to stretch it out a bit.

Not if his runs were in 75+ degree weather. Those IATs look pretty dang stable across the 3rd gear run assuming a warmed up motor and warm/humid May air in Florida. Many underestimate the effect that humidity plays in cooling and oxygen availability.

Apparently you haven’t seen some of my 95F+ logs focused on IATs? I probably have more logs posted here throughout various threads than anyone else.

I’m seeing >10F rise vs pre-pull IATs & almost 20F rise from the beginning to the end of a single gear pull.

Btw, I think he knows this and is still waiting to upgrade his IC.

105.8 max to be exact

He already has a unknown aftermarket IC.

He went from approximately 95 degrees to 110 degrees over the course of a third gear run. I believe he's a 6MT. The 6MT has a very long 3rd gear which runs out to around 108mph at 7000rpms. So over the span of his run ~2,500-6,500rpms, his IATs went up 15 degrees.

Being in FL, he's going to be near or in that timing reduction threshold a majority of the time because the daily driving will heat up any IC fairly quickly, especially in normal driving. Sure, glory runs on a cold motor and cold IC may show slightly less increase in IAT over the run, but is that really representative of the real world or real track driving?

I think some folks believe that a "good" IC should maintain ambient IATs all the time. Good luck with that.

You’re missing the point. A good IC is all about the reduction of IAT rise in each gear. 10-15F is one gear is not good regardless of ambient temps. Take a look at some of the IC/IAT logs I’ve posted.

Even if timing isn’t being pulled from IATs <110F, the cooler your charge air, the more power you make.

He already knows this and is why he’s switching to a larger IC soon.

[AmuroRay]

You're both right.
This IC is garbage. I wish this autologging feature worked better, but that's on me. Like an idiot, I had the display set to go to sleep after 10 seconds, so I was constantly trying to keep the display active while I log.

Why didn't I change it sooner - who knows.

But as for the intercooler and IAT control - it's pure garbage. Temps were about 73-74 degrees ambient according to the cluster, the car registered around 95 degrees during cruising. On a pull it immediately jumps up to 100+ and typically topped out just under 108-112 degrees. I tried to manage the temps so I could get a clean run off - I don't think I can do a full 4th gear run, which is unfortunate.

I think I can get full engine load, giving me the best look at how well the tune is working out.

Absolutely this. I've been wishy washy between the Evo3 and the VRSF Race. I sold my brand new VRSF Competition after taking it of the box and thinking "I should have gone bigger"

If you’re not going to track much, I say get the cheaper VRSF Race and let’s see what that baby can do!

Either of them will be a PITA to install, so no real advantages there.

Car is on jack stands, front wheels removed, fender liners removed. I'll pull the bumper tomorrow morning and work on installing the ER intercooler. I'll take pictures and do an install post once I am done.

ER intercooler and charge pipes are installed. Thanks to bentom2 for the help. Still need to put the bumper and trim bits put back together. I'll do that tomorrow and try and get an install post done.

Just got back from a 25 minute test drive. Was able to get some brief pulls in 3rd and 4th. Car builds boost and IATs start to drop quickly with pace and seemingly boost. Low speed and under vacuum, IATs climb up but will start dropping quickly as you give some throttle and pick up pace. Throttle feels a touch softer than before, which I was expecting from the pressure drop across a larger intercooler anyway.

You noticed lag? Do you have any before and after logs to share?

I drove down from Seattle to Thunderhill Raceway Park on Friday (679'ish miles). The last couple hundred miles in California were 85-105°F ambient. A few 5th and 6th gear pulls for about +20-30mph would end in IATs in the 7-10° over ambient. The interesting bit was how quickly the IATs drop as soon as I start to roll into the throttle.

Yesterday was about 90'ish miles on track with the afternoon ambient temps in the 90-100°F range. The Evolution Racewerks Intercooler worked well. In the afternoon when ambient was reading in 98-100°F range, my IAT for the entire session stayed in the 120-131°F range. If the ambient dropped by 1-2°, peak IAT would drop by 3-5°F. A buddy in a F80 M3 (competition pack) was in the 122-125°F range for his IATs on the stock air/water S55 intercooler for comparison. He's a bit more conservative as a driver than I am. Overall, I am pretty happy with the ER. And I shudder to think what the stock IC would do …

Have you had a chance to compare it against the CSF unit your friend is running? I can't imagine that it can out cool the ER - but it does weigh more so it might take longer to max out it's capacity.

And double check the CP connections - ERs internal volume is about the same as a 5" core, I don't understand why you had lag...You should wrap the chargepipe in reflective tape - It's going to be my recommendation moving forward.

I had a similar experience on my 2013 TT RS when I installed the large Forge Race intercooler. I think it's simply a function of the small pressure drop from a large I/C.

On the M2, I Installed an Akra 300 cell dp on the car a couple weeks ago. It seems to have mostly solved the slightly soft throttle response from the intercooler.
