Intercooler DO88 for Toyota Yaris GR

Description

Description
do88 performance intercooler designed for easy installation in your Toyota Yaris GR!

Advantages of the do88 performance intercooler:
– Larger core volume: 13,971 cm3 vs 7,320 cm3, 91% larger!
– Larger active cooling surface area, 2451 cm2 vs 913 cm2, 168% larger!
– Larger input/output connections: 63mm (2 1/2”) vs 45mm (1 3/4”), 95% larger surface area!
– Air flow at 0,175 bar/2,54 psi pressure loss: 300 CFM (226 CFM), 33% higher!
– Maximum power gain of 26 whp with do88 turbo inlet piping! Measured on a car with a TTE400 turbo, a Syvecs ECU, etc.
– Lower air temperature after intercooler under the same conditions: 25°C (50°C), 25°C lower!

This intercooler is designed to deliver the best cooling efficiency under demanding conditions. During the design process, we decided to increase the frontal cooling area of ​​the core. A larger frontal cooling area significantly improves cooling across the entire speed range, provided the core and end tanks are properly designed. A low-profile/thick intercooler, which is a much easier aftermarket design for this car, will generally only offer better cooling at high speeds (high air velocity is required to force cooling air through a thick core). We saw our design as the obvious choice for this car, as it will also be used on technical circuits with lower average speeds.

To increase the intercooler's frontal cooling surface area, the bumper bar must be moved forward; otherwise, the intercooler won't fit behind it. Therefore, we designed two special spacers that move the bumper bar forward. These spacers also provide an optimal mounting point for our intercooler.

What many unfortunately overlook when designing 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 through them instead of passing through the core. We include two air guides that close these air passages.

To improve charge airflow (reduce pressure loss), we increased the size of the intercooler pipe connection on our intercooler from 45mm (1 ¾”) to 63mm (2 ½”) because the original connections are very restrictive. To ensure our intercooler fits with the original intercooler pipes, we include two specially designed silicone hoses.

The 91% increase in core volume and 168% increase in frontal area is an achievement we're proud of (57mm thick Tube & Fin Core). It's a remarkable difference. Noticeable, to say the least. The engine pulls better across the entire rev range and withstands repeated full-throttle acceleration without generating heat. The idea that an intercooler is something to upgrade only after a major engine modification is false, but widespread among customers and car enthusiasts. On hot Swedish summer days, during repeated pull-ups, spirited driving, or even ordinary driving in a warmer climate, it doesn't take much effort for the engine to generate dangerously high intake temperatures – even on a standard, unmodified car. The cooling capacity with an OEM intercooler is often lower, which will affect usable power. Heat must be eliminated, otherwise the promised power will be diminished as soon as you start to open the throttle. With our intercooler, you can be sure that the power is there, at all times.

Some of the original plastic air guides need to be trimmed (see installation instructions) to accommodate our significantly larger intercooler. The polystyrene on the bumper bar is removed during assembly. The polystyrene is not suitable when the bumper bar is moved forward.

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