The stock intercooler on the 208 GTi is the same compromised side mount intercooler used on the 207 GTi so we know its not up to the job even on a stock car. On a remapped engine with the stock intercooler we were seeing inlet temperatures of 105°C (215°F) – the highest we have recorded on any car ever! This has a huge detrimental effect on power and torque.
Our intercooler is a full replacement single pass (left to right) core which mounts to the stock crash bar in the car. The pipework supplied with our intercooler joins to the pipes that connect to the stock intercooler so installation is easy. The only cutting needed is to the ducting on the radiator to allow the pipework to pass through. All the silicon hoses, hard pipes, clips, bolts, nuts and jubilee clips needed to install the intercooler are included, along with full colour installation instructions.
Performance wise, the car we used had a Superchips remap. We tested the stock intercooler and the Forge intercooler back to back on the same day and the increases were dramatic
- Intake temperature dropped form 105°C to 45°C - a drop of 60°C
- Power went from 190bhp to 224 bhp – an increase of 34bhp
- Torque went from 222 lbft to 244 lbft – an increase of 22 lbft
You can look at the dyno graph comparison of the intercooler showing the increase in performance, but PLEASE REMEMBER this was specific to the car we had in for testing, and you may not get the same results from a stock or mildly tuned car.
