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 |

I understand that. I mean't the stage 2 map that he is currently running.

..interesting choice! I am surprised that you picked an intercooler with a relatively high pressure drop.

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.

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.

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.

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, |

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.
