Updated FMIC info

There are some variables in ambient temp but the results are pretty good for comparison.

Maybe because the guys testing are interesting in performance over marketing & did not think "Dinan's" still unnamed secret modifications to the Spearco made any difference to the end result More then likely they simply did not have one available.

Top secret always means awesome. Like stealth technology, or hover tanks

From the Dinan web site;

"The Dinan intercooler provides a 93% increase in total volume, substantially reducing the pressure drop by 0.7 psi. The intercooler also features larger connector tubing and custom shrouding for maximum efficiency.

"Cool down" time is also reduced, enabling the cars to produce full power under varying driving conditions such as stop and go traffic(or track*). The system has been engineered as a direct replacement for the stock unit, requiring only minor modifications for a clean, factory-like installation."

*(as fellow brother BQ will attest to as he has had longer staying power out on the track than most his fellow brethren, as he uses a Dinan IC).

So, what more could one ask for? More numbers on the theoretical, or plain old track results?

First, the numbers above are not theoretical but actual test runs with all kinds of supporting logs behind them. Second, no one has said the Spearco/Dinan is a crappy unit, just that its middle of the pack & not worth twice what some of the others cost. Of the group I can see premium pricing only for the Helix. BTW the test showed the Spearco pressure drop to be .5 while Dinan advertises .7 - Better to go with the Spearco number

Again, I'll go with proven track results. You can carry around all the logs you want.

Its only worth twice as much if you can install it yourself

Labor does seem to be quoted a bit on the generous side for dealer installed so if you can DIY even better of a deal!

If I could DIY I'd honestly don't think I'd get a single dinan part. If I keep the car through graduation, I'm debating on keeping it as a second car and really see if I can learn on it. As it stands now I have no desire to start pulling things apart especially over the weekend when I'll need it for busy weekdays. Plus I get pissed and I'd probably throw a wrench at the car if it pissed me off. Me and princess have a wonderful relationship right now and I'd hate to have the cops called on me for domestic violence

I really can't wait to try the suspension and see how the car runs with an FMIC.

You are making a bad assumption that the others are not successfully used in competition or track days.

I was not in the SEALS so I don't carry logs much.

Its ok to be jealous I'll have the most experienced techs in the automotive industry working on my FMIC. It will be the greatest automotive accomplishment since Karl Benz.

The thing I noticed was when I slammed on it to intially catch him where I would have had a harder time then reaccelerating, it was basically like a first time WOT at like 80 now I don't want to think with DCI, Exhaust and DP's what it would be like


It seems like any temp savings I may have gained from the FMIC (I'm aware it doesn't cool oil ) I erased with the stock 1 fmic aggressive map.

I read its quite a difference going from stage 1+fmic to stage 2+fmic but you will need the DP and intake. Intake is ok but with DP you will run into problems going to the dealership with the check engine light on...again this is what I've read

I'll do an oil cooler before I do DP's. From what I've read the jump I'm impressed with right now won't be as noticeable going to stage 2, but it'll still be good.

I too think stage1+fmic is plenty for having fun on the streets and its not worth the DP unless you are tracking ur car often.

Awesome compilation in the OP of upgraded intercoolers available for the N54. However, there is a need to clear up some confusion between the Dinan vs the Spearco




^ The N54 Spearco Intercooler here represented in the OP is a different design/specs/size from the Dinan version



Even though the difference between them can be seen, this picture from Dinan's website is a poor representation as the "end tank connections" are not the connections you will see on the actual product for the N54. Below is a clear example of the Dinan Spearco Intercooler with the exact same end connection as the OEM for easy installation



The Dinan version of the Spearco is larger than the original Spearco Code 3. Dinan's claim is a 93% increase in volume over the stock intercooler

What Dinan did is used the Spearco Core to their size specifications that comes in various sizes http://www.turboneticsinc.com/node/84


http://www.turboneticsinc.com/node/86

As everyone can see and it has been made very clear, the Spearco Code 3 and the Dinan Spearco are:

Difference sizes
Difference design

The only relation is they use the same "CORE" technology, that's its

Another thing to look at in their data specs is that:

The rule of thumb for "coefficient heat exchange" for an intercooler is that it should have "less than" 1.00 PSI reduction

All the FMIC mentioned all meet this rule. PSI reduction range of .20 - .90 the less number does not mean better nor does the higher number

The lower the number means higher flow with less "coefficient" and the higher the psi reduction means lower flow with better "coefficient" as the slow down allows the air to cool more becoming more dense before reaching the intake manifold

I don't want to get into what intercooler is better, I will leave that to the individual. I just wanted to clear up the mistake of the Spearco Code 3 intercooler representing the Dinan version.
