The rallye engine is a stock AGU with a superchip, downpipe and fmic
I haven't dyno'd but around the 180 mark???
The airbox in the mk1 was a piece of foam I pushed over the itb's cut out the holes and then I used cardboard tube to make the shape. wrapped in sign vinyl and then I just fiberglass'd over all of that and soaked it in water and picked out the card and foam;
pretty rough as It was all done in a hurry. I'm going to make a gucci carbon version next.
