Nice mods! The car looks beautiful. The aggressive front bumper, Techart wheels, and blacked out tail lights look good together!

As for the pulley, I heard Ernie only got about 4-5 HP out of it. Not the 12 you were originally adding. I don't mean to push any buttons, but 60 HP in a N/A car with Stock internals is pretty hard to do.... hence my questions...
I was told the drive loss calculation for the Cayman S is WHP X 1.18 = BHP. This is from an expert source on the Cayman S as well as PCA techs. And its 297RWHP not 296 I havent dynoed it after the pulley, the current numbers are without it.

The drive train loss is 12% or 1.12 on a wheel dyno and most of the loss is from the tire interaction to the rollers with a standard trans. Direct drive line dyno's or engine dyno's are more accurate for HP and Torque and either eliminate the tires or drive line completely.

I really like the front. I was never a fan of the small round fog lights, looks tough. I also like the Tech Art 20s (right?)

I thought LSD, different dynos and wheel size/weight played a part as well. Someone with a heavily modded Cayman (more than mine) uses HP x 1.18.

trap speeds are a very good indicator of HP. if you really think you are making that kind of power take it to the strip. stock 997s trap around 114, 996 GT3 a little more. considering the highest trap i've ever seen for a CS is Kman-S car at 111 (similar mods to yours) i don't think you make as much power as you think. not flaming you, just being realistic. trying to extrapolate FWHP is from WHP is theory at best. it seems to be in vogue at the cayman club (i see it in a lot of signatures) but i chalk that up to ignorance. you never see anybody talking flywheel HP on modded cars on forums (evo, sti, corvette, mustang, f-body)where there is a large knowlegebase of tuning, built motors, dragracing...

Well then that person is mistaken. Non roller dyno's such as Dyna Pack also only read 3-5% different than BHP compared to roller dyno's.

that difference can also be between a manual and auto... those are generally the percents i've seen commonly seen - 12% for manual, 15-18% for auto...

the amount you mod it really shouldn't make a difference

Love that vent in the front. Very nice. In my opinion there seems to be a bit too much black on the tailights though.
