Ill get some more

Wow....much different setup than ours. Install looks clean as hell...very nice. What drives you using?

the scx uppers and sportmaster lowers , might go to the sc lowers this winter.

Bravo style lowers? Wow....risky. May want to look into the SCX lowers and consider calling Wilson Performance....they blueprinted ours...HUGE difference. I also understand IMCO is working on a new SCT drive...that is supposed to have a much faster lower...and same gear set as SCX???

What speed are you getting out of that bytch?

so far 115 w stock maximus props , waiting on 7 blade 33 props, here are more pics .

There's some more speed in yours that pickup is hurting the speed quite a bit.

Oh I bet there is more to be had for sure....RF's pickup design is trick as hell.

Very clean and sweet setup...thank you for sharing pics. We are hoping for similar speeds...should know more in a couple weeks.

The lowers are the big limitation. There's 6 mph left on the table just with the lowers. A set of sixes & it would scare the HELL out of 130 mph.

Reggie I was concerned about the pickup I have what does yours look like and where does it go ? I am going to get some body work done in about a month now would be the time to change . do you think going to sc lowers or sct lowers would make that much difference

Not on your boat but going to the sc lowers on the one I have here would. The new style pickup we make would definitely improve the speed & handling on your boat.

do you have any pics of the pickups and where would they be mounted ?

Message me your email & I will send you some pics of the pickup.

I dont have the balls to go with SC's. Besides, didnt you tell me NOT to go with SC's Reggie?? :lolhit:

I said you would definitely have more issues with them but they would be faster. I thought I had you talked into it but if I remember imco talked you out of them.

Im just bustin your ballz buddy.

What is supposed to be the problem with the sc lowers?
Allen

The sc lowers are really good. The 42 I'm working has the scx lowers. The scx lower is massive, robs a lot of power but it doesn't break.

From my experience, they are perfect. I have used -2 and presently -3. Never had a failure with a lower sc. Although, I 've had a failure with an upper not with the gears or bearings, but with the upper cone clutch shaft where i have sheared one right off..not damaging any of the gears or bearing, but i am running 750 ft lb of torque..800hp, but that is probably their limitations. if you're trying to run 1000 hp and 900 ft lbs plus, they will probably not hold it, but still will be the fastest bravo setup...other than a #6...

How big of diameter prop can you run with the -3?
Allen

That rules me out, we are over that on HP and TQ. And you cant run big 6 blade Hering wheels on a SC setup....which adds to the coolness factor...:drink:

I dont disagree that they are fast..but after we shelled 3 of them with the old 850HP motors..it was time for a change.

so you shelled 3 imco lowers. What did you break?
Allen

On a -3, the upper if it is a bravo has to be cut and modified like i did my xr's before I ordered imco sc uppers..imco sc uppers are stepped up 1 inch on the cavitation plate therefore putting you right where your -2's would be, so prop diameter will be exactly the same as a
-2...probably 16 inch max. But, my 47 has -3's ...i am raising it 3 inches on the x dimension..therefore allowing me to space down to allow more prop dimension.

I can't wait to get yours back together as well. Your 47 is going to fly with the new stringers,transom,bottom blueprint & the raised x-dimension.

Lots of things....lol. We also went through a couple XR uppers too...

Its my brothers fault....:lolhit:

29 Scarab10...it looks to me like i should be asking you how your set up is holding out..if not mistaken you were the one that won the loto in your class..what is your x dimension and what are you running for props if you don't mind telling me? i am in the process of a major refit on my boat..now running 31 pitch 6 blade hering at about 2 inches below running surface to about 1 inch above running surface with sc uppers and lowers.. any input would be appreciated..

Wow... great looking set up!! Maybe one day we can meet up down in Table Rock to see her in person!!

The motors started life as 500 efi's.The motors are now 555 cubic inchs, have afr 357 cnc heads with Vortech Superchargers, and make a little more power than the 850 (that I call them)however when someone looks in hatch and sees the stock 500 efi intake they do not believe the power they make. They actually made a little more than 1000 in both horsepower and torque. However I am unable to turn them to 5800 rpm in the boat regardless of the prop used which is were it made over 1000. I really believe the 500 efi intake are not able to flow enough volume to support the rpms I would like. I can put on a pair of 31's and spin 5700 or I can spin 34's 5600. My engine builder warned me about this and it will likely get changed before next year

My x dimnesion is 18" and I am running SCX uppers with -2 sc lowers with 1.3? gears ( the scx uppers are geared a little different so I do not now the exact number). Prop is Mercury labbed 34 maximus with 15 1/4" diamater.

The only problem I have had with drives is during the middle of this summer one drive developed a shifting problem. We tore the upper apart and the gears looked brand new (encouraging). The shifting problem turned out to be Imco puts a rubber plug in the hole above the shift shaft. The plug is to long and after a little wear on the cone clutch it would no longer shift. I cut the plug in half and it has been problem free since. The drives are 2 seasons old and have about 180 hours and close to 7000 miles on them. The first season of these drives they had 850 horsepower and 800 foot pounds of torque (about 100 hours and 4000 miles). i guess with all this talk about breaking these lowers we will tear them down over the winter and have a look.

I should also mention that i really believe in Torco #6 drive fluid in these drives. I believe when you use like mercury High performance gear oil that it is so thick that it get slung away from the gears and flows slowly and can not get back into contact with gears (kind of forms an airpocket around the gears) where as the torco flows very similar to water even cold. I have no proof of this but have had great results after changing.

The boat has been 117.9 MPH and this was during August. When the water and air temp cools down I really expect this number to grow.

If you have any more questions I will try my best to answere them.
Allen

good running boat... you should sell it to me for 50k!

29 Scarab..thanks for the comeback..i have also experienced the same problem with my motors..i had them done by MRD in L Island and dynoed by Richy Zul and they have solid lifter cam shafts ..they pulled them to 7000 rpm and made 900 hp, but once put in the boat with cmi elbow tops...tried different props and could only get 6000 rpm without rev limiters installed..i also tried a set of 32 maximus and didn't like them at all..lost about 3 mph. Hering is the only prop i will run right now. i am in the process of ordering 3 7-blade herings for my application. should have my boat complete for the key west poker run...

Id love to man!!!! Get that 26 dialed in and lets do it!!

Its not conducive to chatting...too much for you. :party-smiley-048:

I don't care about that now. I will have intercoms for everyone so we can all wear headsets, and idle, and be able to chat. I will radio you from my CB and ask if you still have the hatch off and the pogo sticks extended.

U will name it Death Bed....and your CB handle will be The Grim Reaper.:evilb:

:greenchainsaw: (MS170)


back on topic:

what is the latest with the boat?

Tyler picked up new piston last night. He has the Stbd motor torn down to bare block and has the #4 hole honed. He will put back together MON/TUE...and ship back to RF...fingers crosssed. I talked with Lil R...he spoke to Dave @ CMI and headers will be shipped back to RF on Tues. As of now it looks like we are still on pace for another trip to Reggies Casa this coming weekend. OH...and truck should be ready on Monday. Please dont blow it up this time. :op:

So what really went wrong with the engine and the header for that matter ?
