Yeah for sure there are pricey options but you have resale and warranty to consider. Anyway I'll leave it at that. I also think the gt3 is plenty fast out of the box and I won't disparage anyone looking for more performance.

It's good that we have options

It's a fully built stroker engine with supporting exhaust and tune, not some cold air intake from JC Whitnety.

Based on the way my car decimates a 991.2 GT3, I’d say the number is pretty accurate.

The most I've ever seen from on-track footage is that it's about equal. But feel free to post something better of course, there is a serious deficit of proper 4.5L footage out there.

Surely you have some willing family members to help out

Butt dyno is not a reliable tool in this instance

Is there serious doubt that a 4.5 stroker Deman Cayman running 98 octane with supporting mods isn't noticeably faster in a straight line than a stock 992.2 gt3?

There is skepticism, then there is just being silly.

Expectation is that it's a bit quicker on the street and a bit slower on track due to intake temp issues inherent to 981 side intakes.. But wouldn't it be nice for at least someone, after dozens and dozens of these have been built, to finally let us find out how quick it actually is? Why is this as big of a taboo as placing a "find out if God exists for real" button in a church?
