Moto East Crawford Power Blocks Testing & Dyno! - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

What is really telling is if you look at the area under the curve on the HP plot of the darker line (CPB). You can see there's more power just about everywhere. Past 7500 there's more on the non-CPB, but only because that car has the rev limit raised that high...nationals level auto-x car there vs street car for the CPB.

I actually pretty much dismissed the CPBs as in theory all they do is move the torque down a bit lower with longer runner lengths, but clearly they did their homework and it places the VE in the efficiency range of the stock cams. So with some cam timing tweaks and ignition fine tuning, we really didn't lose any power, but just gained a bunch right where it matters.

My dyno chart with CPB, crawford's e85 tune, revworks uel, nameless catted front pipe/over pipe, and q300 cat back looks nearly identical to yours. My dyno was also done on a dynojet. I made a 21whp increase at about 6200 by adding the CPB and tune.

Looks good. I am looking at picking up a set.

question. Have to had the chance to try the cpb with and without a f/I application back to back just to see if there is any gain to be had?

No point at all in running the blocks with boost.
