RE: Rookie needs advise ...HELP
 

:cool-smiley-027::D Quesyion ...! ! What would be the real actual speed ...

For a Cigarette 35 Cafe Racer weighing 5511 Lbs , less engines and drives ,

Now with a pair of 502ci / 415bhp year 2000.. with Bravo 1 drives , i guess they weigh 2600 Lbs both of them ,


Total weigh of both & fuel being 8500 Lbs :(


what propellers would you take in consideration ???

to have a good speed .... with this set up . !

is it possible to reach 70mph ???..: with this set up or perhaps if i install extension boxes to lift the X-Dimension 1 inch ....can i reach my target

Whatever:

Thanks

Clyde

I replied in your General thread but I will here too. You aren't going to come close to 70 with 415's. I am surprised at the weight figures you came up with. Sounds LOW....

Someone else with more knowledge of props will have to comment on the props but I would guess a Bravo 24 would be a lot of prop for that setup - maybe even too much??

Also, are you suggesting that with full tanks and everything back together that boat will only weigh 8500 pounds?? Fuel itself will weigh upwards of 1500 pounds.

SFG, I'm sure that published weight is a dry weight also, right? So, 9400 plus 1400lbs fuel, coolers, gear, people.....

Many thanks .for your information...

What i cant understand is how come i was there and saw myself the weighing of the boat and saw it marked at 5511Lbs

will see ..when i rig it ....

But thanks once again :p

No way on the 70mph with 415s.. Props would by 23 pitch depending on the max rpm you want to run.

That's the only way it makes sense to me. I can't imagine a manufacturer posting anything other than a dry weight. Curious about the 5511....

I can tell you this - behind the truck it sure as hell feels like 9400 PLUS fuel, gear, etc.....

23 P - yeah that probably makes more sense.

Either way I love my CAFE....you will too!

I'm sure the approximate weight posted above is including engines and drives. The 5511 is without. Not sure what kind of weight the engines and drives are though.

Certainly. Would be interesting to know if that was with TRS or Bravo?

When did the Bravo's become the standard in Cafe's? That spec sheet if from at least a 1990 or newer.

My Cafe with 500's and Bravo's tops out right at 70. With the 415's I doubt you are going to see 70, maybe 65 or so but not 70.

I has 2 sets of 24pitch 4 blade props if you are interested
bravo
hydromotive

Bolt on a set of pro chargers set at a modest 6lbs of boost and you'll run low 70's all day with any standard prop setup. Speaking from experience..I have the 95' Cafe for sale here with the flag paint job and procharger setup.

They are also very reliable. Never had a problem!

So many thanks for your replies...........

to u all Cigarette lovers :evilb:

I really appreciate the fact and especially your replies ...


Today i woke up with a new set up in mind ...and thats what i am goin to rig ... Thats a lot better than the 502 s 415HP i had in mind ..YEP :grinser010:

To rig my Cafe Racer 35 with twin 525 s ...and XR Drives with extension boxes ! and with Latham Hydraulic steering ...

.because i confirmed with my mechanic and you were all right regarding the weight of the engines plus boat ..that will be 9400Lbs .fully rigged .....

What i am now sure once again is that i managed to weigh the boat once again and the scale went 5515Lbs .obviously without engines drives and dry from fuel...Beleive me guys ...

What would you expect as top speed now ??? with 525 s with less than 150 hours on them with XR Drives with extension ???

and what props would match this set up....

Thanks Clyde ...

The Cafe I had a ways back had 415 HP Mag MPI502's in it.

The best result i got was running labbed 4 blade Spinelli Props (BTW they are not made anymore) If i recall they were 24".

I also had Merc 3 Blade 23" but those were slower and did not get on plane as well.

Boat ran 68 mph at the fastest.

If your boat is originally a TRS boat, I'd look at Konrads before going to the major surgery of re-rigging to Bravos.

On extension boxes, I'd want to talk to at least a person or two before putting them on any boat. They may or may not give you speed increases but they may also give you some negative ride and handling traits. I've heard tell of guys picking up incurable porpoising. It's also going to drastically narrow your knowledge base on prop selection.

The Cafe is a fairly common boat- most of the prop people will be able to ballpark you with a set of props, then swap you into what works best from there.

I figure the cafe with 525 will do 74mph. Not sure if the extention boxs will be a plus or minus to the application. Without the boxs you will probably need a 26 bravo one prop. Just my .02

525sc? or 525efi?
bravo boat or trs?
if bravo leave it
trs>>>konrad
carefull u dont end up with a 110k in a 70k boat

Hi guys .......many thanks for your massive help....

I am learning so much with your replies ...

All my sincere compliments to your 35 cafe racer .......my friend ... GLH ! ! !

hope i will send you my 35 photos soon when ready .

Now In fact i have to answer DREAMER . yes the engines are 525EFIs with XR Transom Assemlies and with XR upper & Lowers ..

Do you think a 76 to 78 MPH would be in reach for a 35 cafe racer ...with those engines... and set up.

I would say that having a ratio of 1.5 in d drives turning 26 Pitch at 5200rpm ...77mph......why NOT?????

Any guess???

and by the way....... if you have any questions regarding Composites , dont hesitate to ask me , Perhaps i could answer your Quests...

ITS my job and life, I am an importer and wholesaler for the fibreglass industry , from boatbuilders to anyone that uses Composites. ( Resin , Fibreglass etc.etc...)

Thanks

prop slip and hull efficiency... the faster u go the more power it takes to go faster...

id gues 75 light load and light chop... labbed props turning in

Hej Dreamer......

Why props turning in and not out.whats the benefit of it..!!!!!!!!!!!!

io thought that tunnel boats benefit y turning the props out......and not mono hulls...


Do you lift the bow or the stern by turning in ????

all generalizations.... each application and boat setup varies...
so learn from what others have done...

but props in can give bow lift... adding blades to a prop gives stern lift.... 3 to 4... 4 to 5... 5 to 6 but then there r different types of props too stern lifting bow lifting...

then ur hull... c.g. .... x demension... notch transom or not... then what type of dives and lowers.....

AND ANY COMBINATION OF THE ABOVE!!!!!


ask around find a tried and true set up... dont worry about that xtra 1-2mph and go boating:drink:

unless u LIKE and ENJOY the testing fiddleing aspect:p

Rookie needs advice?.......stay away from Stecz. :D

GREAT ADVISE - and consistant with Tim @ Cigarette Racing! Cafes. need some stern lift and 4 blades - 525 EFI would be a 26P for starters

Not to hijack the thread, but i have an '88 Bullet, im running three blade cruising props, running rebuilt 454's [450 hp a side approx], bravo 1's, 9800 lbs dry, oh and i dont have a notched transom. wondering what i would prop setup i would get the best top end performance from. I have a decent hole shot, and i could lose a little of that if i got it back in top end. would some stern lift increase the top end? and take it easy on me, i have about 15 hours of seat time in the boat.
I do think the four blade cleavers are kinda sexy, but i dont know if they would help, [could lessen the weight of my wallet though]
Any suggestions??

I too am curious on the best combo for a Bullet. Have seen a couple of threads on this before and what it looks like, the Bullets also like the 4 blade props (I currently run Mirage 27P 3 blade). I run about 550-575HP.
