formula 382 sr-1

How fast should a nonstep 382 with hp500's (carbs) run and with what prop ?

Only a geuss, but around 72 with 26 Bravos (?).

formula 382 sr-1

going to try a set of 26's the 23 had 19% slip at 63 mph @ 5300 rpm we will see in the AM.

Here is a chart that another OSO member put together for the 382 fastech. I have used it and seems to work well. For and SR1 straight hull I would subtract 5 mph. So with that said a 382 SR1 with 500's and a light load would run around 68 to 69 mph.

382 with 500's ---- 382 with 525's

light -- heavy ---------- light -- heavy

74 ---- 70 --------------- 78 ---- 74

Were the 23's Mirages? If they were, I would go with 24 Bravos. Should improve slip and pull your rpm down slightly.

Yes 23 Mirages I a friend that had the 26's I may be able to get 24's and may be 26 labbed. Let you how it does.
