We have recently revised our Astra and Zafria VXR intercooler pipework, after requests from customers, to improve upon an already excellent design. From its existing design, the complete kit has been tested and proven to in excess of 420bhp (the intercooler core is good for 600bhp) with the intercooler utilising 60mm pipework from the turbo (the moment we can step it up from the OE 50mm turbo outlet we do) to the intercooler 60mm inlet. The intercooler outlet was 50mm, and stepped up to 60mm by the start of the OE map sensor pipe which we made use of in our original kit.
