Type 1 2021cc HP?

Post by col72bug »

Hi Guys 'n' Girls, I built a 2021 for my bug (76mm 4130 crank, 92 thick wall barrels and pistons, W110 Cam, ported stock heads, 1.25:1 rockers, 5.4" H beam rods, dual 34mm Webers, lightened 8 dowel flywheel) and it goes really well, and I'm very happy with it, but I was just wondering what sort of HP should it be putting out? I may put it on a dyno some day but for now I thought I'd ask you.

The PerfExpert app gives a decent estimate in my experience. Uses the phones G meter and other sensors. You need to fill in the car details quite accurately. Weight, fuel rank capacity, % of tank filled, aero drag (find that online), tyre size, gear ratios, passenger weight, etc
