Ah, sorry about that. I must have glossed over it.

No worries!

So I just learned something interesting. I was trying to find out more about the Forge intercooler/silicone pipes, and they emailed me back saying they haven't confirmed fitment on the US model...

The crashbar is different on the us model vs the euro spec.

Forge is in Florida though, slightly confusing. From the pics their intercooler looks similar to COBB in design, though I can't find specs anywhere. Was mainly looking into it as another option.

 

[redsilvy]

Oh weird.. that is interesting then.

 

[Etyrnus]

If I was closer, I'd be willing to be a test car, but I'm in NC.

I would go with the Cobb or DHM

Why would you suggest the DHM for a car that doesn't have a big turbo?

That thing has so much more volume it has to affect infill time negatively. I know I can feel it a bit with my J-Line already.

We have already talk about the math time and time again. Fill time .02sec diff. Cobb doesn't even log that fast lol. Also our intercooler has logs that show it keeps the stock turbo cooler than anything else out there. Yet to see logs for the Jline.

I agree with Russ theres no way you would notice a difference in spool/fill time with the tiny stock turbo. What do you want logged on the jline? I have tons of logs with charge ambient and compressor outlet Temps logged.

I'll throw my logs into the data pool for others to look over.

Here's a log showing a 2.7 degree rise over a full 3rd gear pull. This is my car with the J-Line and I don't have any part of my bumper cut out yet. A full 30% of the IC is obstructed right now.

http://datazap.me/u/iso100/randy-custom-base-map-log-2?log=0&data=1-4-5-8&zoom=75-138

Here's one showing a 4 degree rise:
http://datazap.me/u/iso100/randy-cu...t-1-wot-log-1?log=0&data=1-4-5-8&zoom=112-172

Here's a log showing from a dead stop through 3rd gear. This is a 1.8 degree rise:
http://datazap.me/u/iso100/revision-15s-stop-through-3rd?log=0&data=4-5-8-21&zoom=0-67

In terms of fill time I looked at ETC Angle Actual for two of my logs and looked at the time to peak boost.

Stock: 1.09s from 1.87psi to 21.57psi
J-Line: 1.12s from 1.49psi to 23.78psi

That's a 0.11s difference versus stock but it's rising 22.29psi instead of the stock 19.7psi rise. Most importantly the charge temp rise is 3 degrees while the stock FMIC rose 21 degrees.

I'm not saying the DHM IC is not a great product... I just don't see it as the best option out of all the options for people with stock turbos.

Rpm, accel, boost, intake air temp, charge air temp, ect, vehicle speed, ect, and airmass

I this is prob just me... But when you guys are running almost stock boost levels, this "4 degrees of change" stuff isn't very telling. Maybe try some 27psi falling to 20-22psi at redline results. If your turbo isn't really challenging the coolers, than its not really showing anything other than the fact that its properly sized for what your asking of it. My panda cooler may show a 20degree change, but... Its also being overly challenged as well.

Not saying that to show or prove any cooler vs another, just simply stating that other than the stock cooler, none of these coolers are being challenged at stock or 1-2psi above stock with boost that falls below 20psi above 6200rpm. Take that for what it is... Other wise, every cooler available right now works GREAT at stock boost levels.

True to a degree (get it), what we also need is compressor outlet temps (not inferred) if you want to calculate IC thermal efficiency.
Also running a larger turbo with a higher VE you may well see lower COTs depending how hard your pushing it. The few actual COTs I have see running the OEM turbo at stock boost levels peak at around 150c (300f).

I'm just wondering, instead of cranking up the boost so much have you considered increasing timing more instead?

I have over 1200 datalog pulls
I've tried low timing, high boost. High timing, low boost. But so far, what makes the best power for me is high boost and high timing, lol. 24psi at redline with 17.5-18degrees of timing above 6,000rpm works the best, lol.

Iso I agree. That iffered Temp or whatever is very pointless for me. And Russ's big turbo numbers don't tell us much because those big compressors don't get in the same ball park as the stock turbo at the same boost levels. Luckly, Russ also has stock turbo logs too with the big cooler.

Before I reallized that the car had no REAL compressor outlet temp sensor, I was very confused in what I was seeing in logs, lol. 350+ degrees was not un-common, but thats because if I was running the stock turbo, that's close to what they would have been. A fat compressor wheel helps a lot with that though

Well damn, if high boost and high timing doesn't result in negative corrections then that's the way to go! Jealous.

 

[iso100]

Did you know that ambient temp is inferred too? I don't even bother logging it anymore and just make note of the cluster temp for outside temperature.

"Why would you suggest the DHM for a car that doesn't have a big turbo?"

My perspective is always from a road race course on a hot day aspect and from max power from whatever turbo is on the car which to me means at least a Cyborg if not bigger, more power, etc....

The J-Line worked very well in 70 degree weather, Cyborg, etc.....

 

[iso100]

For a track vehicle that makes sense. For a daily, not so much. Mishimoto is already bigger than needed...
