The S55 turbo engine that powers the BMW M2C / M3 / M4 F8X uses a Top mounted water-cooled intercooler instead of an “regular” air-cooled intercooler. This OE intercooler has a tube and fin core with clamped plastic end tanks. This construction has its drawbacks since it is prone to crack and start leaking coolant into engine or leaking boost pressure out of the tank sealings.

Our mission when starting this development of a new performance intercooler was to eliminate the OE intercoolers weaknesses and of course offer a great performance increase. During all test we have carried out during the development of our entire BMW F8X M2C/M3/M4 product range we see clearly how the peak power is directly equated with the IAT (Intake Air Temperature).
To get an exact 3D-model of the available space to design our intercooler in we did a detailed 3D-scan of our M3 Competition engine bay. In our Solidworks CAD-software we tried out several design concepts for our charge air cooler using the 3D-scan generated model.

The final design concept was decided after several CFD simulations in our Solidworks Flow Simulation software. In this software we can simulate air flow and measure pressure drop and air distribution over the core. We decided not to include internal air guides since several of our simulations showed they did more harm than good. The air flow is distributed perfectly over the core with our tank design without internal air guides as many claims is good. But in many cases, these causes turbulence and disruptions in the airflow.

Our final design resulted in a bar-and-plate core with TIG-welded aluminium casting end tanks. This offers a peace of mind for any High boost tune. We have managed to utilize a massive core 85% lager than OEM and decrease (16% lower) the charge air pressure drop and maintain drop-in installation without modifications. Decreasing the charge pressure drop over the intercooler has several benefits such as the turbos needs to work less to achieve target boost / lower temperature / improves throttle response. We have the equipment to calculate the pressure drop in our CFD calculation software and also real-world tests in our Superflow SF-1020 flow bench. On the water coolant side, we changed to a dual pass flow structure which allows the coolant to flow across the core two times before exiting the intercooler instead of the OE single pass structure.

We use a high density offset cooling fin on both the air and water side. Several tests were performed to find optimum balance in-between the air and water fins to get the maximum heat transfer. This gives our intercooler a huge increase in active cooling area compared to OE.

Naturally, this being a do88 performance product, we have executed thorough, severe, and continuous tests developing this product to ensure best performance. Not one compromise has been made.

All this hard work result in a product that in one way or another really will enhance the performance of your vehicle no matter if it is a standard car or a heavily modified monster! On track, on street, on strip, this charge air cooler will be your true companion!

Good but not Wages of Fear
The much maligned Sorcerer is in fact a good well crafted thriller that if seen without refrence to the Original Wages of Fear would have faired far better at the hands of the critics. That's not to say the film is perfect. The opening scenes that fill the viewer in on the charecters back stories, are pointless and actually work against the tension that is built up later in the film. Knowing exactly why the characters are desperate makes their reasons for taking on the deadly task seem a bit lame and looses the exestential angst that creates such a hopeless atmosphere. Once in South America the oppresive nature of their stay in the village is also diminshed by knowing too much about them. Having said all that there is still an air of desperation and mounting frustration, it's just not as clausterphobic as it could have been. Once the journey begins the tension is turned on, the only problem is that by knowing the original so well there is not quite the frisson of that classic. This is an unfortunate by-product of re-making any well respected film. Friedkin however has a fair go and if this is the film you see first you will wonder why it was so slated on original release. The film moves at a well constructed pace that is aided by a cracking score from Tangerine Dream. The cast perform well and Roy Scheider is reasonably well cast but does not deliver the subtly nuanced performance he is capable of, for this you need to look towards (obviously) Jaws and to a lesser extent the minor role he playes in Naked Lunch. All in all a good film, though not great, and as the review starts by saying, not Wages Of Fear, but it deserves a better reputation than it so unfortunatly has and will be a good addition to anyones collection of interesting 70's films (the best decade for American Filmaking by a long long way).

Harrowing Cult Classic!
If you are considering this film, no doubt you know that it is a remake (or hommage to) the classic French thriller Wages of Fear. Chances are everyone is also familiar with the outlines of the plot--a group desparate men agree to transport cargoes of unstable dynamite through 200 miles of South American jungle to put out an oilfield fire. Of course the drivers know they have voluneered for a suicidal job and the odds are against the survival of any of the truck drivers. That alone puts Sorcerer (along with Runaway Train & Sam Peckinpaw's The Wild Bunch) into the rarest category of films: the big-budget Hollywood existential! My view, a distinct minority view, is that William Friedkin's remake surpasses the orginal as an exercise in suspense and harrowing, relentless action. Like many other fans of this movie, my introduction came during the 1980s on cable movie channels. Few people saw Sorcerer on the big screen. The film was initally panned by critics and cited as a prime example of a young director with too much ego, power and money creating yet another Hollywood box-office disaster. Gradually, the film acquired an audience and a legacy through word of mouth. Today many critics see Sorcerer as the last great product of the seventies generation of young Hollywood film-makers. It is no accident that Sorcerer and Star Wars opened the same day!In many ways, the film marks the transition from the courageous experimental Hollywood of the seventies to the family blockbusters and action franchises of today. Fans of Sorceror appreciate the director's commitment to the story of desperate men risking everything to escape a very realistic, modern version of hell on earth. The opening backstory sequences show us how a small-time New Jersey criminal, a disgraced French banker, a Mexican assassin, and an Arab terrorist find themselves driving old trucks that can (and will) explode at any moment. The film has a hypnotic, dreamlike feel and the viewer will be drawn into a dark journey that can only end one way. The score by the German band Tangerine Dream is at once seductive and chilling and contributes to the growing atmosphere of susense and dread. If you like stylish action and relentless story-telling, you should not miss this film. The DVD quality is OK but perhaps we might hope for a remastered director's cut with better special features at some point.

My teeth look 20 years younger!
Wow, this is the first toothpaste that has actually worked in whitening my teeth. For reference, they were mildly yellow, I'm a daily coffee with creamer drinker. I feel like this toothpaste has taken the color of my teeth back to how they were in my 20s. I like the fresh taste and smooth texture. The tube is smaller than regular toothpaste, but I believe in quality over quantity. I'd rather pay a little more for a quality product with better end results!

You need to read this....A+ stuff!
Ok, I have to give my honest opinion here.... I had (yes past tense) two teeth that had small stains on them and the last time I had my teeth cleaned at my Dentists office he stated he could not remove the stains... So, I read the reviews on this toothpaste, did some more research on Google and got it today. After lunch, I brushed my teeth and looked and the stains and they seemed to look lighter. I thought hummm.? Really? Then after dinner, I brushed my teeth again and just looked into the mirror out of curiosity (been a few hours) and I don't see either stain at all ... completely GONE! I am being very honest and so surprised that both stains were gone... Yeah, I know what you're thinking when you are reading this...B.S. right? Well, I am so surprised myself that I ordered two more tubes since they're on sale and I plan on giving one of them to a friend that has some coffee stains on her teeth and see if it works for her too... So, I would have to say that by purchasing the two tubes that I did, was way cheaper than going to my Dentist that stated they couldn't get rid of the stains. I'm totally 100% impressed with this Crest 3D White .. my new go toooooo forever! P.S. I am a ice tea drinker by heart and sometimes coffee too. Signed: So impressed by this stuff and it actually taste good and made my mouth feel fresh and my breath was fresh for a long time too....A+++++ toothpaste! Quick Shipping as well.....

Beautiful white teeth
This works great. I always keep my teeth, nice and clean and bright and white and usually I have to buy Dental whitening, but this is the first time I found a product that you can just brush your teeth a few times a week and it keeps your teeth, nice and white.
