The time has finally come! We are officially able to announce the highly anticipated 6870 CEA GEN2 from Precision Turbo & Engine and release our test data. I will tell you upfront, it's exactly what we were promised and everything that we hoped for. I had the privilege of enjoying the 6870 CEA over a weekend's time and can personally attest to how much fun it is having a turbo this size making this much power!
I apologize for the dirty turbo pictures. We were so excited to start doing the testing that I didn't get a chance to snap and pictures of it out-of-the-box.
SP Built 3.0L Motor w/ SP-spec Wiseco 10:1 pistons, Manley Turbo Tuff 625+ rods, Titan Billet Mains, ACL-X Bearings
SP Built Head (stock ports, performance radius valve job, standard size valves)
GSC S2 cams w/ Supertech valvetrain
SP Racing F1 Manifold (OG single-wastegate prototype design)
No QSV used during testing
4" Trucker Flapper Exhaust (no Cheetah pipe this time )
GReddy 3-Row FMIC
SP 3" Cold-Side & 4" Hot-Side Intercooler Piping
ProEFI 4" Throttle Body
ProEFI Pro128 Standalone EMS
Test Fuel: Ethanol
We have 4 different setups to present data for. They are as follows:
#1 - PTE 6870 CEA GEN2 .81 A/R (undivided)
#2 - PTE 6870 CEA GEN2 .96 A/R (undivided)
#3 - PTE GT42-7275R CEA .98 A/R (divided)
#4 - PTE 6766 CEA GEN1 .81 A/R (undivided)
As you can see, this collection of turbos will allow us to present a very diverse "best case" scenario for power output of three different turbo sizes, two of which being the 6870 CEA with two different turbine housing sizes. It should also be noted that the PT6870 is the only CEA GEN2 turbo in the bunch. There will be a few additional variables to discuss but for now, let's get to the pictures, videos, and dyno graphs.
