Just ordered the Trask performance check-mate ventilated transmission cover, just a preventative measure to reduce any pressure build up and gets rid of another peace of plastic (not sure about freeing up some hp as stated though)- https://rolliesspeedshop.com/shop/transmission-final-drive/transmission-bt-6-spd-era/transmission-externals-bt-6-spd-era/trask-performance-checkm8-vented-transmission-top-cover-black
Rode it, pub on way home, $6 VB schooners still, by god there is nothing that is more fun than riding these fuckers, makes shit disappear.
So you drink schooners of VB ?
