Dave, I have your setup and love it however I have just added a Night Fury cam and an OD Cog rear drive on my maggie to keep my boost around 11psi. Due to the new blower speed I am now seeing IAT's around ambient to 10 under compared to 20-30 below ambient before latest upgrade. How would the 30% larger core help and what is involved in the upgrade? thanks again for all of your support in the past..
