It's 3 mph at the 1/8th too, but the times are damn near dead on. Hell, my speedo is off 2-3 mph too so maybe it's reading that output instead of the actual speed.

I think the times are more than accurate enough.

Also a couple days ago I noticed alot of people are wondering about the negative boost readings.

About 3 years ago when I started playing with the n54 I realized there are two map sensors:

1. In the charge pipe that reads up to roughly 23 psi and picks up unrealistic spikes due to the throttle body. This sensor also does not read vac.

2. On top of the manifold, this sensor reads vac, but if my memeory serves me right is only accurate to something silly like 3psi.

I am assuming cobb is flipping back and forth btwn the two depending on throttle angle

Running 235/35/19 front and 275/30/19 rear.

Stock was 225/45/17

So, roughly 2% off stock diameter.

I don't really care for intercoolers as I've been running meth for 50k the ets was used and cheap so I pretty much went why not.

Fmic performance data is provided by the vendor, not an independent third party. I would take the advertised pressure drop or heatsoak suppression data with a grain of salt.

Btw, I have the same fmic as clap.

Cool. It makes sense if you got a good deal on a used unit and you are running methanol injection! I was just curious. That's all.

Anything instead of the stock crap will perform well especially with meth.

Just curious...why would you say you don't care for intercoolers, even with meth?

...because you can dump enough methanol in the system to lower the IATs below ambient...

If one is relying heavily on methanol injection to reduce IAT's then the only important characteristic of an intercooler would be the pressure drop. You'll want to have an intercooler with minimal restriction of flow.

In my opinion, you're not going to be running meth all the time, so why not get a decent intercooler?

Just my thoughts.

When people are comparing aftermarket intercoolers they mainly focus on pressure drop and cooling. All the fmics out there are close enough to one another as is. When you add meth it really doesn't matter when it comes to IATs cause from a 60 to 140 run if I'm 8 degrees over ambient it was a hot run. As far as pressure drop...you guys need to stop believing bs claims made by manufactures.

IIRC cp-e measured the stock FMIC pressure drop at btw 2-3 psi - which is why it's as effective as it is, i.e. the air stays in there longer and has more contact with the cooling surfaces. That 2-3 psi over manifold pressure measured at say 15 psi means you're turbos are pushing 17-18 psi. A bigger unit with more surface area can achieve the same cooling efficiency with less residence time, i.e. less pressure drop. I don't know the numbers of the ets unit but if it's say a 1 psi drop your turbos aren't working as hard. In that case, the FMIC doesn't need to be as efficient as the stocker as your turbos aren't working as hard and your preFMIC temps will be lower to begin with.

Hi Clap

As far as FMICs go ETS is very similar to stock in pressure drop. you can see this in there data with IC inlet temps the same as stock suggesting similar inlet psi. ETS also confirmed that flow is similar. This makes an efficient cooling unit, but not so good pushing high boost as others have stated. BUT the other manfuacturers don't really give much info anyway, so all the options maybe similar to stock... they are much larger of course. A couple of the largest options may have higher drop though... like the big tom option. just speculation.

Clap welcome back;

Are we talking about the 5" or 7 ETS FMIC?
Im currently looking into buying one getting ready for stage 2, however its either AMS or ETS 5". I know AMS is a 100$ more but what do you guys think would be best for the COBB stage 2?

THanks,

THanks,
I have the AMS FMIC, have had it for well over a year (maybe 1.5?) but I live it. I have COBB as well and I am waiting for stage 2. You can't beat the end tanks, and I can tell a HUGE difference at high RPM's with being able to sustain power as compared to the stock FMIC (testing done on a SSTT a while back). I feel like AMS probably has the best combination of flow, light weight, low pressure drop, great cooling, and efficient use of the "hole" in the front bumper.

The AMS and HPF end tanks are almost identical. As a matter of fact the two intercoolers are almost identical as well. Both are great choices!

I would go with HPF if I felt I needed a "bigger" FMIC but I was hoping it weighed less (big HPF fan in general). Even if you wanted to dump enough methanol into your manifold to run consistent 50 degree F intake temps, I still would have to change out the stock FMIC connection... that baffled connection on the charge side which is at a right angle and drops to like 2 inches in diameter is such a crappy flow design.

Thread Jacked!

I also use the ETS FMIC and think it's great.

As for Stage 2... since when does summer end in September?
