With the Temperature at about 77F, the Best G-Tech run I could get was 14.8 sec for 1/4.<br>Also immediate repeat runs with out cooldown period produces slower results again into the 15's.<br>This highlights a few problems to me with the A4 1.8T.<br>1. Intercooler Problem. This may be solved with either or both a larger intercooler and better air flow to intercooler.<br>2. Turbo heat affecting intake charge. This may be a bit more difficult to solve.<br>I have noticed with just normal driving, the Intake ducting is quite warm. With some hard driving<br>it is very warm. One Idea is to install a extra heat sheild between turbo and the complete run of intake duct.<br>The intake duct must in my opinion must radiate some heat into the fresh air.<br>Another Idea is the installation of a cone filter with a Heat sheid. This would be of no benefit to norml driving, just produce more noise, at spirited driving should help with fresher(cooler) air.<br>A improvemnt would be to design a new duct that is sheilded that has a larger scoop positioned in a different place. A word of warning here, The currect opening of the duct is positioned so i does not have a direct run through the front Grill so as not to pickup water/rain.<br>The More I look at these issues the more complicated it becomes to come up with a reliable solution.<br>A expensive way to go is to get a S4 frot bumber whick has more room for intercoolers and<br>intake positioning.<br>One suggestion was given to me was to use a SAAB intercooler positioned infront of radiator,<br>this would also reduce some ofthe distance in turbo piping. The A4 has some of the longest piping I have seen in any car.<br>Any thoughts on the above anyone?

Contact Christian Long for a pic. He cut vents behind the intercooler into the wheel well. I can't make myself cutting the sheetmetal:(<p>Another thing you are probably familiar with is that an additional air intake duct could be run from the lower passenger side front grille directly into the air box if only one of the horns (or what the heck it is) is moved just a bit. But then you run into the water/rain problem. This, however, I believe can be solved.<p>

Lucas, I may have mentioned this before but Denlo up here here in Sydney have developed a scoop to mount around/ behind the intercooler which flows more air from around walking speed upwards.<p>On a test car they had with the VAG hooked up the intake charge was consierably lower, I cannot remember the figures but it made the difference between the engine retarding due to excessive intake charge heat and not retarding.<p>That should go a long way to helping.<p>Graham

<br>MTM makes a air scoop that fits into the front bumber, replacing the grill work on the intercooler corner. It will increase the flow almost 100%. I aso louvered the inner well. You can buy louvers prestamped. I got mine from Land& Sea, which are made for outboard racing motors. Just use a 3" hole saw and pop rivet the louvers on. Sportwheels sells the air scoop...ask for Dave Petersen...tell him Scott sent ya. I need the points!!

I'm currently using an ABT front mount intercooler along with the stock unit in my TAP stg 7 A4. This intercooler is almost a perfect fit inside the stock bumper. I just have to be careful not to park the car too close to the curbs! I'm also considering modifying the intake. Right now, I'm using the Jamex filter that came with the kit but it is positioned at THE WORST possible location: right above the turbo and next to the external wastegate! I already have a heat shield fabricated to shield the turbo but this isn't enough. I'm looking into fabricating an intake tube which routes the filter to the lower front bumper area though I haven't thought of a solution for blocking rain and snow yet.
