I think it'd be helpful / nice to show an example of an ideal log. What kind of temperature increase is normal, acceptable? Obviously a ton of variables. This is nice but it'd be awesome if someone did an intercooler shootout on the same car / climate to keep consistency.

This is only for those with upgraded FMIC, not stock FMIC. NO METH

• Logging Parameters

Boost

1) FMIC
2) DCI or CAI type, model
3) Stock inlets or upgraded inlets (1.75" or 2.0")

So here is mine to start with, ambient temps were 79°f forgot to log it a few days ago when I was doing 100-200 kph comparison with other groups

This log made me notice I have a "hitch" in my power delivery. Boot jumps at 4,300 RPMs as does load, etc... I had this once before and cleaning DVs eliminated the issue. But, I recently servcied the DVs... ARGH!

Any atm logs? My old atm held pretty flat iats through 3rd.

Would love to keep this thread alive.... An "ideal" datalog would still be helpful for those trying to make some sense of what is good and what is not so good.

[Jeff@TopGearSolutions]

It's hard to say what is ideal as there is never an apples to apples comparison with different cars, with different mods in different areas doing different pulls with different heat soak.

But the general rule of thumb for a 3rd gear pull is about 15 degrees above ambient.

The only way to know if YOUR car is going to be better with a different FMIC is to actually conduct the test on YOUR car and keep the data as controlled as possible.

Interesting comparison

Stepped VRSF
http://datazap.me/u/puppydax/fbo-v4-...a=1-4-15-16-23

Stock FMIC (my log)
http://www.datazap.me/u/mwahlert/log...data=1-4-17-24

Similar ambient temps, similar jump in IAT over a 3rd gear pull 25-27 degrees F rise... although the VRSF car is running several more PSI of boost through the pull...

Nice looking log. Not a good comparison, as MAPs/fuel/psi were different.

[Tiago@VRSF]

The comparison has to be done on the same car at least in order to find an accurate delta. Here's a couple independent logs from customers:

[LMB335IS]

Don't any of you guys do multi gear pulls? I want to compare my #'s with other 3rd-5th gear pulls. I don't think I've done a one gear log in years. It's the 4th, 5th, 6th gears in a multi gear pull that matter as far as IC temps go. Just about any IC will work for one gear, but it's the multi gear pulls at the strip or 1/2 mile events where the IC can make the difference between clean timing or pulled timing.

Are these logs from two different customers/two different cars..... not to mention with different psi/tunes, and different air temps???

Here's a multi gear pull, with warner's 8 inch FMIC
It is nice to see how high and how fast these IAT's will climb. Also how fast they will recover.

To most people it doesn't matter. Even a 3rd gear pull is straight to jail speed if caught and rarely does a street encounter on the highway involve more than one shift into 4th and a shut down. People who do half mile events need an intercooler better than the 99.5% of people who do not do 1/2 mile events.

Nice pull Nick. 3rd-6th? Exactly what I was looking for, a forty degree rise over 4 gears whereas I'm seeing a 40 degree rise over 3 gears here. We'll need to run once you get back home

Perhaps you speak for most people in Va, certainly not here. As a matter of fact, I find it to be quite the opposite where I live. One gear pulls are a abnomaly, two plus the norm.

The two logs I posted aren't intended to be directly compared to each other.

Also Wagner doesn't have a 8" FMIC.

5th and 6th pulls?! LOL

I'm not a grandma, trust me I've been upwards of 190 but asking for 6th gear pulls is a bit over the top!

I have trouble completing 4th gear where I am.

I have a 3-4 though for arguements sake.

Stock Inlets
ETS DCI
ETS 5" FMIC

Start 84
End 109 Top of 4th

Ambient were about 80F with plenty of heat soak. I can't complain about 25 degree rise in 2 gears but I'm sure it could be better if it was an ETS 7", ER 6" or even Wagner Evo II Comp.

DCT cars have shorter gears, so its very easy to go through 6 gears in which others would end in 4th or 5th

Shit, I'm old enough to be a grandpa. I guess I'm just fortunate enough to have to 3 mile long, straight as a arrow road available in a industrial area so nights and weekends are wide open for runs. Pretty much every log I do is a 30-130+ run. I use a VBOX as well so I can really quantify tuning changes or upgrades.

Appreciate your post and log though. Two gears is certainly better than one. I'll PM you for any further IC inquiries since I'm thinking of changing things up

I have the straights, just not without 1000 other cars at any time of the day LOL

Feel free to reach out. I may be changing the FMIC up to a Wagner Evo 2 comp. I'm currently fixing up the suspension since I'm an Xi and it handles like a turd on ice.

I agree, it seems like 99.5% of the modded N54 FL community do more than a single gear pull.

Although our gears are shorter, our final drive is longer, when i've ran a AT is seems like our shifts are pretty much at the same speed... I suggest we add MPH to compare this... New thread?... lol
