Description

do88 high performance intercooler designed for easy fitment in your Toyota Yaris GR!

Benefits with the do88 high performance intercooler:
– Larger core volume: 13,971 cm3 vs. 7,320 cm3, 91% larger!
– Larger active cooling area, 2451 cm2 vs. 913 cm2, 168% larger!
– Larger inlet/outlet connections: 63 mm (2 1/2”) vs. 45 mm (1 1/4”), 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 the DO88 turbo input! Measured on cars with TTE400 turbos, Syvecs ECUs, etc.
– Lower post-intercooler air temperature under the same conditions: 25°C (50°F), 25°C lower!

This intercooler is built to offer the best cooling efficiency under severe conditions. When developing this intercooler, we were determined to increase the frontal cooling area of ​​the core. A larger frontal cooling area significantly improves cooling across the entire speed range along with a properly designed center and end tank. A shallow/thick intercooler, which is a much simpler aftermarket design for this car, usually only 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 the obvious choice for this car, as it will also be used on technical tracks with lower average speeds.

To increase the frontal 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 also became an optimal position to use as mounting 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 passing through the core. We include two air guides that close these air passages.

To improve charge air flow (reduce pressure drop), we increased the inlet/outlet hose connection size on our intercooler from 45 mm (1 3/4”) to 63 mm (2 1/2”) as the original connections are very restrictive. To ensure our intercooler fits the original intercooler hoses, we include two specially designed silicone hoses.

The 91% increased center volume and 168% larger frontal area are an achievement we are proud of (Tube & Fin Core 57 mm thick). It's a noticeable difference. Noticeable, to say the least. The engine pulls better throughout the rev range and can handle repeated full-throttle revs without building up heat. The perception that an intercooler is something to be upgraded only after a major engine tune-up is false, but widespread among customers and drivers. During hot Swedish summer days, during repeated revving, inspired driving, or even ordinary driving in a warmer climate, it doesn't take excessive engine effort to generate dangerously high intake temperatures, even on a standard, untuned car. The cooling capacity of an OEM intercooler is in many cases lower, which will affect the power draw. Heat must be dissipated, or the promised output will be reduced when you start applying gas. With our intercooler, you can rest assured that the power is always there.

Some of the original plastic air guides must be trimmed (see installation instructions) to accommodate our significantly larger intercooler. The polystyrene on the bumper beam is removed during installation. The styrofoam will not fit when the bumper beam is moved forward.

This product comes with everything needed for easy installation. Bolts, washers, and assembly instructions are included, of course.
