Anyone ever thrown on an Intercooler for the 24* series Turbo. I am told this is at least a 20+ HP boost but am wondering if it is worth my time. I have the original 244 Turbo (Oil Cooled).
Adding the intercooler is definitly worth your while. It provides several advantages:
1) cools the intake air considerably which creates a denser air mass which increases power.
2) the reduced intake air temperate does not promote detonation which can seriously damage the engine
3) you will be able to increase the boost which provides even further increases in HP.
Most Turbo Volvo enthusiasts look at installing the intercooler as the first mandatory modification.
