Well, back to Proven Power to dyno the new Zed
The weather was perfecto (SAE CF was 1.0) -- so conditions were ideal for a "true" set of measurements (by comparison, my old Z's baselines were taken at temps over 100* F, and all measured values were a good bit lower across the board, even with a more generous CF that attempted to account for the hotter temps).
Below are the best runs, all taken in 4th gear with oil temps between 180* - 195* F. Other runs hovered within 2-4 whp of the highest runs, but I can post them as well if folks wish to compare and contrast in obsessive detail.
First, bone stock vs. Cobb smooth tubes and humble K&N panel filters. Excellent gains for such an inespensive and easy to install mod.
Behold the detailed comparison to see where big vs. small gains were picked up throughout the rev range. No tuning as yet. Just the tubes and filters.
Last, my "bragging rights" dyno, so called because it uses STD correction, which invariably overestimates gains on NA cars (it is more appropriate for FI cars given that no CF takes changes in air temperature due to compression into account...).
Qualitatively, I'm a pretty liberal guy by nature, but when it comes to quantitative measurement, I lean conservative -- thus, I prefer SAE estimates (a bit stingy) for NA cars over STD (a bit overly generous), but here they are anyway as legitimate (if overly optimistic) numbers for consideration.
Headers, CBE, and tune coming soon
