Looking to upgrade me 03 cobra from a ported eaton to a whipple 2.9 or kb 2.8 or possibly 2.8 mammoth. Any recommendations out there?
Also anyone have any issues buying a used one?

Based on the OPs power goals, and pump gas limitation...I second this.You'll run out of octane before you run out of blower. I definitely say tvs now.
I spun my 2.9 whipple crusher to 30 PSI with a 4 lb lower and 3.0 upper. Mid range torque on the hit finally felt good.
I then put a 2.3 TVS on with a 4 lb lower and a 2.8 upper and loan behold I had no idea what I was missing out on. Instant mid range torque just went up to a whole new level of fun.
To me it seems if instant hardcore torque is what you're after on the hit the biggest twin screw you can find is not the way to do it.
Not to mention my 2.9 setup broke about 5 or 6 lower pulley assemblies and custom welded up locking plates before I ditched it in fear of it finally taking my crank snout with it.
Here my 2.9 collection was just getting started
Notice one on the left got the threads snapped right off
The 2.8 is a powerhouse as well! If you are going to go that route I would get the liquid cooled. I know a guy in Morgantown West Virginia that has one of those and he's in the mid 600s on pump with plenty of room to grow...What about the kenne bells? A lot of whipple info so far but before I lean towards the tvs should I even consider the kennebells? Or same boat as whipple 2.9
