Here is a comparison of the exhaust housings (18P v 20P) You can see how the 18P cartridge height is different with the 20P being much shallower. We machine this out to take the same height VF48 18P cartridge and also modily the internal vane of the housing some. Checking the photo will give you a good idea what needs to be done

Ok South Australian Time Attack State Champs Round 2 run and won on Sunday.

Once more Betty White victorious in Club Class up against 15 or so other cars, but a lot tighter at the top this time with Betty running a 1:17.126 to take P1 over a seriously modified EVO 9 with 1:17.138
Pics and official results to follow!

Congrates Martin.
The new p20 housing is working then?

It must be....although it showed only maybe 10awkw in the midrange on the dyno and nothing at the top end (compressor too small by the seems) Made some minor aero tweaks though that gave some great results

Note the new sticker on Bettys front guards (one on each side) which got the EVO crew a little worried...

Well done Martin

Group buy on those stickers?
