New top speed!
 

Ran my 99 35' Sunday and hit 98.2 gps!

Wow, what size engines?

500 efi's with Whipples making about 700 hp.

Lookin 4 that 100 mark!

Congrats - that's moving. What are you running for props? How many rpms?

put some small pulleys on it! Was that with the -2's?

Props are 32 Bravos out of the box, 1.36 Bravo 1 drives with standard length lowers and nosecones. Rpm's were 53-5400.

Did you up the boost?

I really don't want to mention this because I'll never catch you. But are you considering -2 shorties? Labbing the prop? I wonder where you should be propped, rpm wise?

Nevertheless, congrats again.

Boost is still @ 6lbs and I did pick up a pair of Imco -2 shortys from someone here on the board but one has bad bearings which I am in the process of getting replaced, of course the guy forgot to mention that before I bought them but told me after the fact that he did feel something but they ran fine for him! Now tells me sorry but you bought them used "as is"! :mad:

Nice job, Indy!

Try herring props, i believe they are like 600 bucks but that will up your ante by like 2-4+ mph

WOW, you are moving ! Let us know when you hit the magic mark, I'll bet it won't be long.
Congrats to you.:cool:

In your dreams!! 100 shouldn't be too hard at all running that power!!

congrats

True
Did you try it with the shorties?

Not yet, been too busy with work, holidays, etc....

Congrats on that ! Next time give us a call and well come out and get some pics of that 100+? if ya keep knock'n on her door she'll let you in!

Will do, tell us about your magazine.......

New offshore racing mag that covers nothing but High
Performance boating!
(Races, Poker runs, kilo runs, ect.) If Its fast as hell and on the water it will be covered in the magazine.
The first issue goes out tomorrow and our web site should be up in a week or 2

I finally installed the shortys and ran a pair of Hydro P5 29's last weekend, the boat ran 97.4 @5500 in flat water. It handled great, planed off perfect, great acceleration did not blow out through turns. Yesterday I tested the Bravo 32's and the boat ran 96.8 in good choppy water. Boat did not plane off well and the props blew out pretty bad through turns. I have a pair of Hydro Q4 30's to test also but so far the best bang for the buck is the stock lowers and Bravo 32's which handled good but not as good as the P5 shorty combo, I feel like the Bravo 32's could be labbed to get my rpm's up and get me to 100 with the stock lowers. I will test the P5 29's again in some chop to see if I pick up a few mph. Any input from you guys that have been through all this would be appreciated.

Wow! Those are great looking props, Lee! Are you at the rev limiter @ 5500? if not, consider labbing the P5's so you get the best of all worlds, handling and speed. How's the mid range with the 5's vs. the b1s?

Carder,
The mid range is best with the Bravo's and standard lowers, also the boat planed off well and I dont remember it blowing out in turns, mid range is very close with the P5 shorty combo though. I need to run the P5s again in some decent chop to see how much speed it picks up before I make a decision to keep the shorty's and P5's or go back with the Bravo 32 and standard lower combo and put some cash back in the bank. :D

No No - the new Herrings are going for 50 cents a piece - really.

You have an awsome rig - engines/drives looks beautiful - what does the boat look like - congrats.

Thanks! The boat has the classic signature graphics but have I have a local painter that has been working with me on a custom cyclone paint job.

sounds like some one has been playing. congrats. i might expect to see a little more speed. it seems that you didnt pick up much speed by going to shorties. 104 or 106 should be around the mark. i would guess anyways. 33x15 1/4 hydro p5's labed and maybe15 thou of cup and trim the diffuser ring.
this prop on a 1:36 shortie behing an its gimbal an messaged 575's( bouit 700 h.p) runs 109.
check your slip numbers.

good luck

Thanks for the advice, I am a little dissapointed with results so far, considering going back to the standard lowers and Bravo 32's and putting my smaller pulley's on the Whipples, that would have to get me over 100 and put some money back in the bank at the same time! :D

the standard case for height may be feasable but it will blow out the prop so maybe try a set of surface piercing lowers standard length not shorties.
also what rpm does the boost come in?
i know on our set up with whipples we come in around 3800 and we make around 13-14 psi of boost.

the boat ran 98+ with standard length lowers, side water pick ups, nosecones and stock bravo 32,s. I am running thru transom water pickups. have not run the hydro q4 30's yet with either set up. Boost comes in around 4000 and makes 6lbs max. The motors are stock 500 efi's with 160 hrs and maybe 50 with the whipples, I have a pair of smaller pulleys but really dont feel comfortable running them without going through the heads first. where should I go from here?
Thanks!

Did you lose speed going to shorties?

I did with the Bravo 32's...top end and cruise but still have more prop testing to do.

you may have an agressive x dimension from the factory. maybe try standard length imco or merc lowers. with the 32 bravos or a maximus or hydr p5 with the shorties.
this is where you will understand why a true performance facility charges what they charge for dialing in a boat. however being just as analitical yourself in this process will yield similiar if not the same results. keep at it.
also what is the diameter of the 32's?

32's are stock

I can't imagine that your drive height from that period would be too aggressive. I know mine wasn't. I did benefit quite a bit from the -2" Imcos.

call julie at throttle up and give her your numbers as for speed and rpm with the shortie and without.
also you will need a bigger wheel with the shorts and i personally like the hydro p5 for speed and decent planing.

Hey Bo,

What's the difference between the p5 and p5x?

the x's are designed to give the boat more bow lift.
in my experiences at least with fountains, the p5x's and p6's added chine walk and some instability in the high numbers during calm water runing.
