Paul, I dont understand, why do you say that there can not be an intercooler in place between the turbo and the intake? If the piping was cut and made round, then everyting can be made simply.

Are you saying that any draw through system will not effectively accept an intercooler?



Good day Andrew,

Any system can be mad to work in just about any configuration you choose, but it will take considerable time, effort and $$$. That being said, trust me, do your self a favor and stay away from the draw through systems. I am no expert, but here is what I know. In the draw through systems both the air and fuel are mixed and sent through the turbo where they are both pressurized and then sent to the engine for combustion. Problems with the draw through system are numerous. My number one problem is that the addition of an intercooler leads to an almost impossible control of the air fuel mixture through these types of systems. The intercoolers are designed to cool air not fuel as a result the fuel tends to fall out of the air mixture and puddle inside the intercooler. You have no control over the air fuel mixture when random puddles from inside the intercooler enter the combustion chamber. Another problem is lag. The draw through systems is responsible for turbo charged engines getting a bad rep for lag. Again because both the air and fuel travel through the turbo the fuel atomized in the air moves slower and contributes to lag. There are numerous other problems associated with the draw through system, but my main problems center around the ones aforementioned.

The draw through systems are by far cheaper than the blow through system. Its just logistics. Fewer parts, less boost, less power output. But my question has always been why let the system limit you. With a complete blow through system the sky is the limit. Want more power turn up the boost, not enough boost change the turbo. I am not afraid to say it. "I am greedy". I want the power. If something close to 500 HP is good enough for you then by all means build yourself a draw through turbo system. But I would have to ask why when you can easily buy a create motor that puts out 500 hp normally aspirated, so why bother with the hassles of turbo charging. Want to exceed 500 hp, believe me you will. Then a blow through system is for you. I have built blow through systems from junk on a shoestring budget trust me they all kick ass for what they cost. I have nothing to gain weather you go draw through or blow through, but I just thought I would share with you and hopefully save you some of the time, money and aggravation that I had to endure in these past few years building turbo charged cars.

Trust me I am crazy, I even turbo charged my shifter go cart. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
