Awesome! Now the community can get together and compare hard data. It was tough for me switching to a new platform(been a Mustang guy). Hopefully we can all pull together and start comparing real-time numbers with the data logging capabilities of this car.

 

We need to see some logs from guys running the DIY set ups too.

ATP FMIC: Cobb Stage 2, Cobb Intake

datazap.me | stainlineho | ATP FMIC 3-4 Shift Cobb Stage 2

~20* RISE in charge temps over 3rd gear pull and shift to 4th. I need to get a full 4th gear pull log.

This pull was made at 63F day according to ST temp. I also logged IAT and it starts around 71F and go down to ambiet during the pull. You guys think a FRPP intake snorkel would would improve that?

 

I'll throw my $128 intercooler in the mix, from my CXR DIY project. This one is close to the starting temp that you guys were running.

CXR DIY- log starting temp 37.2, 6015 RPM in third gear temp:40.3... 3.1* RISE over a third gear pull

And the OP can feel free to add it to the OP, it's not copyrighted

It's a cool comparison and all, but there are a lot of other variables not accounted for. I'm running 24psi down low.

 

I've been stalking for a while and originally decided on Moutnunes MP275(whenever they get CARB approval), or piecing together my own with FSWERKS intake pipe, Levels/or ATP FMIC, and Randys tuning. However, seeing the datalogs from how CPEs FMIC performs I'm curious, just want to verify pressure drop.

 

Great data. Need some more upgraded ic cars to post logs.

 

The problem with those is the start temp. That 20* in start temp is going to have a huge effect temperature drop. Would be better if they where all at the same temp. I can't rember the formula off hand but. There's a formula that will show the effective change over 2 diff temps. Simply 40 over 200 deg is going to have a greater cooling effect then 60 to 200.

 

All those start temps in the OP are within 5* of each other.....

Wouldn't different density altitude's skew results?

 

39 vs 42 vs 59. ? Um. That's not 5

Sorry I miss read that I see it

 

Had anyone pulled a log with a stock intercooler? I've been watching charge temp (although I am not experienced with tuning and trying to learn) today it was around 50* ambient. Just riding around with spirited driving it stayed around 10*-15* above ambient putting the hammer down I saw a spike to 101* but it shot right back down to 10*-20*. Should I be looking at the spike?

 

You have to make a full pull like you would on a dyno to see how poor it is. Start at 2500RPM and make a full pull to the limiter.

 

I've got a few give me a seconz

stock run on the levels car added to OP

 

stage 1 cobb map, on the dyno 4th gear pull 6,000' in elevation (makes a difference)

start 77*, end 156*

datazap.me | cnstman | Cobb Stage 1 Focus ST

 

Can we get this? McLaren P1 Supercar Tested in Extreme Desert Heat [Video][Photo Gallery]

Lol, I know the heatsoak of a stock ST is borderline, but what can the Vendors provide?

 

Thanks for putting this comparison up. Hopefully we can get some more people to contribute.

 

Definitely want to see the CXR and Godspeed here.

 

I'm not alone....I cant decide and probably wont until I decide to do the turbo upgrade. I'm worried with a bigger FMIC the pressure will drop and my little tiny turbo will have to work harder to flow the same amount of air. I want the upgraded FMIC when I purchase a bigger turbo. PM if you guys have any input on that.

 

This is from a previous post in my Treadstone TR8 diy thread:

I ran my first datalogs tonight. I drove around for approximately 30 minutes to ensure the car was thoroughly warm and then I ran five back to back logs. I never turned the engine off and I only stopped to save each log and then I immediately started the next.

Ambient air temp: 48f Engine temp: 195f

Over the five runs here are the average charge air temps: Low Temp- 47.6f High Temp- 66.1f

Average temp increase: 18.5f

Lowest temp increase: 15.86f

Highest temp increase: 22.36f

These runs were ran in 4th gear from 2500-6100 on 23psi.

Here is one of the logs: http://www.datazap.me/u/14stred/7?log=0&data=1-2-12-14

Which core was this?

Treadstone

 

If you want to see logs from a DIY fmic I've posted 25 of them on the spark plug option thread. FSW tune, Cobb tune, stock plugs, NGK plugs, 3rd gear pulls, and 2-3-4 gear pulls.

 

Treadstone TR8 intercooler on my GTX2867R ( 339 whp pull ) This was in 4th gear, on a dyno with fan about 3 feet away. Not the best conditions for testing the intercooler.

Started at 1546 RPM @ 64.6 and ended at RPM 6714 @ 85.8 This was a 4th gear pull. Boost 25/26psi midrange, 27 at redline.

Overall rise.... 21.2

Need a datalog to go with that. CATs are dependent upon a number of variables, boost being a big one.

 

I added a link in my post for a log.

 

View attachment 3rdpull1015.zip

here's a pull of mine with a Buschur Racing FMIC, stock piping. around 3k rpm in 3rd gear, started at 18*C, ended at 6900 rpm and 23*C.

 

So is cobb fmic and cpe the best?

 

They are the top 2 yeah... Both are damn good

I have the CP-E so I am bias but of course it is the best lol
