We are heading to Lake Don Pedro this weekend. Its a summer kick off with a bunch of family friends, but we will have to meet up sometime for sure.

tnothin, What kind of speeds are you getting out of thr 29 with the 575?

Right now Im seein about 81-82 on gps. Last weekend we were doin 80 with about 80 gallons of fuel, 4 people and a lot of beer in the cooler. But Im having the prop re labed this week, hopefully we will go a little faster.

what size prop are you thinking, A friend of mine has one also .He runs about the same speed, But I think he is running the smaller blower pully.

Im keeping the 30 B1. Its spinning to the right, I know my buddy has one and does 3 mph faster with a left, but it is easier to break the drive by spinning to the left. Our boat is still bone stock. In another 4 months when the warranty is up I will probably do the Chiller and the pulley.

tnothin --

carney mentioned my boat -- i freshened my 575 this past january and banged the rev limiter on the first run with full tank of fuel on flat water

i installed a smaller pulley (old 525 SC pulley) -- making 7 psi boost on a 50 degree evening -

so i ended up getting a lab'd 32 Bravo 1 which put me at 5300 rpm and 86.5 mph GPS --

just installed water injection to get the high boost temps under control -- seems to be working nicely but the weather has been 85+ and humid = 84mph -- waitng for another cool nite

Do you have the chiller on there? What drive are you running, are you getting away with runnin the stock XR? I am only seein about 80-81 on gps right now thats not in the right conditions, thats with about 1/2-3/4 tank and 2-4 people. I just got my 30B1 labbed and it made a big difference in mid range and getting on plane but havent really tryed the top end yet. I can tell it is more efficent though.(80mph, 4 people 70 gallons fuel, 90deg. out) Are you spinning a LH or a RH? And what speeds were you seein why it was stock?

Would appreciate any advice.

Thanks, Chambersgc.

tnothin,

no chiller - went with water injection instead - had to do some milling and drilling, etc to install nozzles under throttle bodies.

running a stock 1.5 XR drive and a 32 lab'd RH Bravo1 prop - nothing special

extra power came from freshening motor and having to shave heads and deck block .010" each - produced a little more squeeze -- plus the smaller blower (top) pulley

I have a thread on the Prop forum -- "TMI - 4 or 5 blade"
My drive is definitely high but i am not sure if i want to lower it or not (using spacers) -- it slips more for sure getting on plane but it worked perfectly to get my rpm's down off the rev limiter -

only thing i am waiting for now is cooler weather to compare my baseline 86.5 mph to the water injection set-up --

it looks like my oil temp has dropped 20 degrees under long pulls, so i assume it is doing its job

If you know how to drive the 35 its a safe as can be.
Dont pay attention and just as Reggieraft says, God will pay you a little visit! BUt man its a rush!
The 35 canopy boat at a 119MPH is a handfull!!!!!
