To the OP, a ton of people in here are passing along bad info. Cooling IATs is only one part of a the role of an intercooler. Therefore, methanol or nitrous should have zero effect on your choice to upgrade your stock intercooler. The pressure drop across the stock intercooler is the second enormous reason to upgrade that intercooler. I think most tests show a 2 psi pressure loss across the stock core. The aftermarket ICs are under 1 psi normally. That means your turbos don't need to work as hard to create the same boost.

To the OP the god has spoken and you should listen to him since he is NEVER wrong and always passes on the definitive answers. Bow to the god people!!

For all the help I have offered you, I am not sure why you have taken on a rude tone to me now. Oh well. Thanks.

If I am wrong, please show me. I am open to learning something new. I just find it rather frustrating when people pass along bad info. This is like the old days when people said you would blow up your engine if you run more than 14 psi.

From the Snow Permance FAQ:

11. Do I need an intercooler with Water/Methanol Injection?
Up to approximately 30 psig of boost, water/methanol injection (using 50% methanol) will provide all the density increase/detonation control needed in most applications. Of course, intercooling and water/methanol injection would provide even greater benefits, especially beyond 30 psig of boost. Most air-to-air intercoolers are only 50-65% efficient. For example, with 11 psi of boost and the resulting 120°f air charge temperature increase, an intercooler reduces the air charge temperature only 60 degrees. Also, an intercooler will reduce boost 2 - 4 psig. on average.

A bigger/better FMIC will certainly help, but given that you're not starting with no intercooler, personally I'd add meth first and then squeeze the last bit of performance out with an upgraded FMIC.

I have to agree. That is good advise!

From an IAT stand point, you will gain on longer gear pulls with an upgraded intercooler and on this car gain about 1.5 psi with no extra stress on the turbos since the lower pressure drop.

Or you could still get the FMIC simply because it's good for when you don't want to run meth / because it looks menacing behind the front

Not being rude...every sentence you start off with lately has been people spreading false information, and that my information is the correct one....take a look at lately at your post...I am just saying there are better to relay your message than saying information is wrong, and my info is the correct info! Thats why there is such a phrase as IMO!

If I came across as harsh, then I do apologize. With respect to what I said, it is not an opinion though cn555ic. This is a fact. I am running about as much nitrous and methanol as anyone in an N54 and I really do speak with experience on the subject. I can tell you that I would not run it on a stock intercooler period. Methanol and nitrous IAT cooling does not solve the problem of very high compressor rpms. Sure the cooler air will allow the car to hit slightly lower boost targets for the same horsepower, but they simply mask the real problem... the heat generated by turbos spinning way beyond their efficiency range. By putting a more efficient core with a lower pressure drop, you are gaining a free boost with no extra effort from the turbos at all. Why wouldn't you want to run an extra 1.5 psi with no extra effort?

What hotrod did should not be condoned as a good idea. He ran what he wanted to run. His times have never been repeated. No one knows what was going on with that guys car. No one knows what the condition of his turbos were. It is a real anomoly.

This.

Steven you need to take the hit for this one, Hes on the money.

Thank you. Increased flow through a larger more efficient core, less pressure drop compared to the stock unit makes for consistent power under an extended, high load run.

IATs aren't the entire picture that many are led to believe.

Bear in mind, hotrod ran at Sac Raceway, again known for their inflated traps. If he trapped 119 at Sac tune only, it would be closer to a 116mph run at a fair track.

Take a hit for what Matt? I am not disagreeing with him...The only thing I find wrong in his setup period is running nitrous and methanol and having a tune with no timing control whatsover, and that surprises me...It also surprises me with all your knowledge of tuning why do you promote a tune that has no timing control whatsover?? I am very puzzled....
Someone stated that hotrod didn't have an upgraded intercooler when he made his record run, all I said was with nitrous the IATs are out the door, I guess I left out the part about boost pressure drop, but then again when running nitrous there is no need to be running anywhere near 17-18psi and 13-14psi IMO is efficient enough.

18psi + meth + nitrous, 10 second run easy; provided you don't grenade your motor. I want to know how THAT feels

I am running 16 psi + meth + nitrous. On pump I put down a delta of 235 rwhp before destroying my clutch. It is very fast.

[cn555ic]

When I finally get nitrous integrated with the Procede I plan to only boost around 14 at max....I am sure 16-18 is crazy fast!

for nitrous applications, I'd go manual over auto. You'll likely fry a clutch instead of the whole transmission. At least until Shiv gives us full nitrous safety. Then I might consider going on the bottle!

[M3 Eater]

stock ic is restrictive... any change there may allow more boost to reach the throttle body. I hear people who's car has come alive after the fmic upgrade. Even folks that are using meth. It will be my next mod for sure. Yes it will reduce heat soak for back to back runs but there is more to an fmic than just cooling IAT as former boosted said earlier. I believe the myst added his fmic after meth. He should have a good testamonial as what can be expected. I too wanted to use meth as an alternative for the fmic and even though it does add some octane to the mix, the upgrade will give you noticable gains. Everyone running the big tom fmic is saying that they have taken off an upgraded fmic and replaced with the big tom out of curiosity and are finding their car is running stronger than ever.

Any fmic is an improvement when takeing out the stocker.

can't wait to do mine! I hate the thought of taking off the front bumper. I have been reading how the helix will let you swap with no bumper removal.

I will say I did have to jump through hoops to get my nitrous safety to a level I was comfortable with. I had to find a TPS tap, RPM tap, install a wideband 02 sensor, etc. I still firmly believe an aftermarket wideband safety setup is critical to nitrous safety, but nonetheless, I do agree that safety is key.

The 6MT is going to hold a lot of power IMO. I have run a lot of high horsepower cars and the this tranny feels incredibly strong. I am sure this is why BMW shares the 6MT (ZF Type G) with the M5 and M6.

Hotrod sprayed through gear change and yeah that would definitely not a good setup, but the way Shiv has it to be setup, it will be rpm dependent and gear dependent with all the other safety parameter before nitrous is even triggered, so even if AT I am confident that the tranny will be protected as much as possible..
