Description

Do88 high performance intercooler designed for easy installation in your Toyota Yaris GR!

Advantages with the do88 high-performance intercooler:
– Greater volume of the nucleus: 13,971 cm3 versus 7,320 cm3, 91% larger!
– Larger active cooling area, 2451 cm2 versus 913 cm2, 168% larger!
– Larger input/output connections: 63 mm (2 ½”) versus 45 mm (1 ¾”), 95% larger area!
– Air flow at 0.175 bar/2.54 psi pressure drop: 300 CFM (226 CFM), 33% more!
– 26 HP peak power gain along with do88 turbo input! Measured on cars with TTE400 turbo, Syvecs ECU etc.
– Post intercooler air temperature lower under the same conditions: 25°C (50°C), 25°C lower!

This intercooler is built to offer the best cooling efficiency in difficult conditions. When developing this intercooler, we were determined to increase the front cooling area of ​​the core. A larger front cooling area significantly improves cooling across the entire speed range along with a properly designed center and end tank. A thin/thick intercooler, which is a much simpler aftermarket design for this car, usually just offers better cooling at high speeds (high air velocity is needed to be able to push cooling air through a thick core). We considered our route as the obligatory choice for this car since it will also be used on technical tracks with lower average speeds.

In order to increase the front cooling area of ​​the intercooler, the bumper beam must be moved forward otherwise the intercooler will not fit behind it. Therefore, we designed two special spacers that move the bumper beam forward; these spacers have also become an optimal position to use as fixing points for our intercooler.

What many unfortunately overlook when developing a new intercooler is the need for ambient air guides. The air passages around the intercooler should not be left open as much of the cooling air will flow there instead of going through the core. We include two overhead guides that close these overhead passages.

To improve charge air flow (reduce pressure drop) we increased the size of the inlet/outlet pipe connection on our intercooler from 45mm (1 ¾”) to 63mm (2 ½”) as the stock connections are very restrictive. In order for our intercooler to fit the original intercooler hoses, we include two specially designed silicone hoses.

The central volume increased by 91% and the frontal area larger by 168% are a result we are proud of (Tube&Fin Core 57 mm thick). It""s a notable difference. Noticeable, to put it mildly. The engine pulls better at all speeds and tolerates repeated full throttle revs without accumulating heat. The perception that an intercooler is something to be upgraded only after a major engine tune-up is false, but widely held among customers and drivers. During hot Swedish summer days, during repeated pushing, inspired driving, or even ordinary driving in a warmer climate zone, it does not take excessive effort on the part of the engine to generate dangerously high inlet temperatures, even on a standard, untuned, car engine. The cooling capacity with an OEM intercooler is in many cases less, which will affect the power consumption. The heat must be removed or the promised production will be reduced when you start administering gas. With our intercooler you can rest assured that the power is always there.

Some of the original plastic air guides need to be trimmed (see installation instructions) to make it possible to install our intercooler, which is significantly larger. The polystyrene located on the bumper beam is removed during assembly. Styrofoam does not adapt when the bumper beam is moved forward.

This product comes with everything needed for easy installation. Obviously, bolts, washers and assembly instructions are included.
