Hi guys I finished testing my 419 here are the stats.

before procharging.....................5% m1 procharger x 3
502 x 3 mpi................................502 x 3 procharged mpi
5200 rpm= 66 mph.....................5200 rpm= 81 mph
25p mirage.................................28p bravo props X 3
1.5 gear.....................................1.5 gear

The problem is i am still bouncing of my rev limiters. there is 100 hrs on the motors. do i repitch my 28 to 30 and lab them, knowing each pitch is 200 rpm drop.this will increase the load on the bravo drives. But there are 3 of them. or do i change the limiters to 5800 rpm and increase both boost and working rpm on 100 hr motors. thx

only 66 mph before procharging?

go to labbed bravo 30's and raise the rev limiters to 5400 and go boating.

If i put the 25p 4 blade bravos on and opened it up on water with a 2 foot chop I could get a 71 mph on gps. with 2 people aboard. but i lost alot of mid range due to lack of chop on my lake. Most of my boating is on a small lake and river. Its an sr1 non stepped hull so it needs the chop. boat is comfie and well built. In other words heavy !

Try some stock Bravo 1 30's to get a baseline and go from there.
