CBRD bbk full, 25.9 peak, 409whp/329wtq
This is a nice build we did for a client of ours-
The car has the following:
CBRD Street Cylinder head, CBRD FMIC, CBRD 1.5" Radiator, CBRD LICP, PTE 1000cc Injectors, Pierburg boost solend, Synapse diverter valve, Invidia O2 Housing, Perrin intake, ETS UICP, turboback no cat- JMF/CBRD tubular manifold, S2 cams
93 octane fuel, 80 degrees in dyno room, 41% humidity- nice humid PA day LOL!
Nice flat curve- conservative ign advance (2 degrees at 3800 up to 13 degrees at redline).. AFR in the mid 11's
Car makes a nice broad torque curve and excellent peak power- typically I run these cars at 28 or so psi, but this car is making such good power below 26 psi (24.2 at redline) that I left it as is-
Here you go:
Cheers

MOST of our road race and street builds use a built cylinder head on stock block-
makes it easy to achieve another 20whp typically at lower boost and extends the torque curve so we can run lower flat boost-
I can get some pics up sometime next week!
Thanks for the kind words guys!

Just noticed this thread and I am amazed at the broad flat torque curve you were able to produce, great job!!
Do you feel it is the CBRD cylinder head work that allows for this in combination with the BBk turbo, good tuning, or a combination of both?
