Having had the stock fmic, spearco dfmic and an mpx fmic on stock turbo, i'd just get a bigger fmic honestly if your going to run pump 91-93oct. If you plan on running e85 or water/meth all the time, then the stock fmic will be plenty fine as the e85 will keep combustion temps cooler than pump gas and the water/meth will cool the air right before it reaches the throttle body
During 3rd and 4th gear pulls the air charge temps would go WAY above ambient on stock fmic.
On spearco dfmic, they would still heat up about 35-45* above ambient, much better than the stock fmic though
And on the mpx, temps stay pretty close to ambient, maybe 10* more on very hot days.

Seriously through, I see that it isn't a "useless" mod on a stock turbo car. To each their own. I personally would do many other things first.

Fucking THIS!!!!!!!

Well I am still on stock turbo and other than going E85 or meth i think ive done just about all I can do on stock without going big turbo which I dont have the budget for right now .

Tuned DSP
Bigger injectors
straight pipe exhaust
blablablabla those are the main performance mods , im working on getting a return line set up and look into E85 since it seems like a better option over meth .

As far as the IC goes seems everyone has had different results with BFMIC on stock turbos >__<

Sorry, Jay, but you are wrong. The crash bar has a very important roll in the overall performance of the front crumple zone, and replacing it some welded up bar stock is nothing but using a piece of toilet paper on a machete cut.

That thing is a seriously engineered piece of HSS whole purpose is twofold. One is to crush and absorb crash forces directly, lengthening the time the impact takes, but more importantly, it redirects that crash energy into the front subframes, who's job it is to stretch out that impact time and change sharp impacts over a short time into less peaky forces over more milliseconds, reducing injury overall and helping the airbags keep your ass alive.

Why a crash beam is a good thing.

Testing intercoolers objectively requires a four-groups design: before and after with the old intercooler, and before and after with the new intercooler. Without looking at all four data values, you either miss out on establishing a baseline for comparison, or you miss any performance changes. Either way, you'll have no way of telling how the new intercooler affects the way your setup runs. For $180 shipped, the CXRacing Direct Fit is probably the best value for the dollar - performance gains may be minimal (although in most pump gas applications, heat soak will be reduced enough to justify the expense), but at least you won't be out $600, nor will you experience a 5psi pressure drop, as you would in the event you had invested in a BFMIC that doesn't measure up. For big turbo pump gas applications, the CXRacing DF will probably not be satisfactory. I'm buying this intercooler for my bolt-on stock turbo and putting it in next month.

It's been years since I've seen it, but someone did an amazingly good flow vs efficiency test on all sorts of intercoolers. eBay crap ones, Spearco, stock, the gamut.

You boys need to find it. It's somewhere. I've read it and heed it because it is real bench flow numbers, and those don't lie.

If you want an intercooler, get one. Not a crappy one, a good one and do it one time. It's been shown that you can do without or with just fine with the stock turbo. If you even think you will come close to maxing out the stock turbo or switching to a big turbo, get the BFMIC (a good one). If you are a chicken liver or feel the need to track your car, get one of the crash bar replacement thingys. Do not waste your money on a direct fit. Go big or forget it.

By the way, don't misconstrue my input as hating on BFMICs - they're a great investment for big turbo pump gas cars or cars running very high boost in general. All I'm saying is that they're generally overkill for a stock turbo car that isn't maxed out, and not worth removing the crash bar for when perfectly adequate direct fit intercoolers are out there.

There was another thread where _Nick_ did a comparison on his stage 3 car with a stock and the AGP DFFMIC. While the AGP was better, the stock IC was ok. He wanted to keep the crash bar and some money, so he sold the DFFMIC.

Yea but wasn't he heat soaking like crazy at the track?

When he did that datalog he was also pushing the turbo pretty hard and he even said in his thread that the test he performed was probly harder then what most people would push the DFMIC.
