We have a single web page for our R32 MKV development & products:

http://www.hp.net.au/hpgolfr32m5.html

There are also individual dyno graphs of each stage of modification. The initial product development was carried out over 3 separate cars in a 9 week period.

We chose to build headers for this vehicle to pick up where other manufacturers actually lost HP & Torque from more conventional header design. We also tested 2 cars back to back, one with a catback exhaust, the other with a stock exhaust - the only difference was less than 3 wkw, so we decided to not persue a cat back system. Headers are available in either mild steel or full stainless steel. 100% Australian made.



The headers work best when coupled with a high flow airbox, the BMC CDA is the best we have tested for this application. The combination of the two will see gains of ~15 - 20 grams / sec of mass air flow.



The software was done in conjunction with DMS automotive from the UK, good results by itself and even better when coupled with our headers & airbox.

Software alone:



Software / headers / airbox (Note the torque increase).



We have now upgraded in excess of 20 new R32's around the country, with very positive results.

Also don't forget your Haldex upgrades, including the official Haldex switch & cable for the R32 too!
