100 MPH PULSARE?

ttt. I am taking mine in to have it looked at for a price on a wider pad. He has a lift so when it is worked on i can modify my trailer. Any opinions on how far up from the transom the wider pad should go and how wide? min of 10 inches i am thinking. Probabally the last 5 ft of boat for the wider pad and how agressive can the blend from the 6 inch part to the wider area be?
 
Good to see ya KCT...

When I first joined the forum there was a guy that had a wider pad. Do a search, and I bet it would come up. I think his screen name was TCAT or something...
 
Yeah, the guys name was TCAT.

I haven't seen around lately. The guy who did the work to his pad did it so you could hardly tell. He didn't really mess with anything much, just widened the pad and blended it in from what I remember. Unfortunately, the pics were hosted elsewhere and now are gone.

Here's a link to the thread where TCAT actually figured out that his pad had been modified.

Hope it helps... :)

I have just found this thread and wish i would have found it sooner i have a 2005 2100 BR with a completely simonized 2004 300x motor hanging on the back i have been trying to get to the 100 mark for month and half now 14 inches of set back boat is completely stripped of all uneeded items and a bow cover has been installed i have been on three trips to the Sacramento river this year trying to achieve this feat best so far is 94.6 GPS spinning a 29 pitch mazco re4 I think it is going to take more ponys to get to the holy land of 100 MPH so for now i am just going to settle for this speed and as soon as simon gets the 3.3 dialed it will be getting done to my 3.1 will let you all know when it is done.

bravo 1 ,

I spoke with Eric multiple times. He told me of your setup. Could you elaborate on some of your modifications ?! Do you run an adjustable fuel pressure regulator ? if so, what fuel pressure are you running ? Do you know your current compression ratio ? is that with stock heads ? or are you running Simon heads ? if so, what cc domes ? what kind of lower are you running ? where's your propshaft in relation to pad ?

I'm sure I'll have more ???'s bear with me I'm trying to dial in my setup.

Thanks,

Paul
 
Bravo,

You have nothing to be ashamed of! Congrats on the speed.

Have you tried any 3 blade props....I have this pipe dream that there is some magic 3 blade out there for this hull.

Hotbeek thinks I am nuts, and he is probably right.

HD
 
I think the ultimate topspeed prop will be a three blade !!! My experience with three blades has been that they are about 2-3 mph faster than most 4 bladers. The overall performance of a 4 blader is hard to beat.



Yeah hotdaddy is nuts that's a whole new thread !!:poke:
 
Hey Hotdaddy,
I am running a adjustable regulator (at 48 psi at 4200 foot above sea level and 51 psi at seal level on the Sac River and still raising) that i got from summit it was for a honda car eric should have the part number and i will see if i can find it for you , my heads are from Eric as well they are 48 cc heads (150PSI) i tried some 46 cc heads but i had to run race gas at sea level and it is not to readily available on the river. My Lower unit is a TM that Titus coned for me and added a little bigger Cav plate for a little better hole shot and it also helps with the low speed porpusing ( i can cruise at 20MPH with out it bouncing all the time) motor has a 14inch set back and is any where from 1 inch above the pad to even with the pad depending on conditions.
Hotbeek, i do agree that a 3 blade prop is faster but the Mazco re4 is so darn easy to drive very very very little chine if at all, all the way through the RPM range also carries the boat very well loaded or not my only compalint with this prop is at elevation it is very slow to plane. might poosibly try some 1 inch spacers on extensions to move it back just a little further. Also am thinking of trying a 29 MAzco Re3 to see if i can get a little closer to that magic number. one other thing i need to do is to Fab up a cover for the bottom of the jackplate extention should help it get on plane a little easier.

Hotdaddy,
any questions you have i will try my best to help with i am also still working with this thing as well. I had a blow out 2 weeks ago on the Sac river that scared the crap out of me a little 2 much motor height but it just kept gaining speed so i kept raising and at 94.6 she got really lose on me. next time i am going to try that more height and less trim once i get my bells back where they belong.

one more thing about this 100 MPH quest for the 2100 Pulsare i dont think that the money needs to put into the hulls of these boats but rather the horsepower of the engine these boats could and will get to the magic number with just a good motor and setup alone just my 2 cents and just my goal

Jupiter Pulsare and I were talking about some Pulsares running in the low 90s now with stock set-up. What do you guys think it would take to get a Pulsare over the century mark? Could it be stock or would you have to modify it?

I had a 2100BR w/ a 300X and SM gearcase that would run 90-91ish (gps) w/ a Mec ET. I always thought there might have been 2-3 more mph left in the rig but I sold it.

-How much weight do you think the boat would need to shed to run 100?

-Could the hull do it on the current (6", I think) pad? Or would you have to widen it?

-Of course the hull would need to be blue printed.

-Hydraulic steering would be a MUST.

-Could the boat break a 100 w/ a stock 300X or 300XS? Or would you have to have someone massage an engine?

I wish I had the money to custom order from the factory a real light weight Pulsare 2100. It would have a smaller gas tank, balsa floor and stringers, and maybe a composite transom. No interior except for two cut down race bucket seats.

What do you guys think?

Simon motor (300x) and a stipped down hull 24 inch wheel. Maybe 95 but a 100 never> thats my .02 cents. the #'s just dont pan up.
 
Thanks for the info Bravo....

One more question, are you running 1.75's. You may have disclosed that and I just missed it...

BLOWOUT AT 95MPH:eyecrazy::eyecrazy::eyecrazy:

Glad you are OK!!!!!;)

A Simonized 300X (even with a 1.62 l/u) will be all over the rev limiter (6800) with a "24 in wheel". On top of which it will only net you around 85MPH.

So you are right, with that set up 100MPH = never.
 
bravo 1,

Thanks for all the info. I too believe the Pulsare could reach 100 with correct amount of HP. Would it get there easier with some hull modifications probably but I'm not a fan nor am I skilled in hull modifications so I'll stick to the engines. I know with the new 3.3 stroker that has surfaced it definitely has the potential to get there. I wouldn't be surprised to see HP nearing the 400 range. Just like anything speed related as you reach toward the milestones it gets infinitely tougher.

Keep up the good work !!

Keep us posted ! :bounce:

A 24" wheel wouldn't work on a 3.0L. Maybe if you had a SUPER HOT 280 and could spin it 7800 rpms with 1.62 gears with 8% slip would get you 100. :confused:

Bravo, You need to bring your boat to Florida. Sea Level and Salt water will help quite a bit with hitting that majic number!!! I think you guys need a DAH lab finished Chopper 29 to get there!!:thumb:

Hey Jupiter,
would love to come to florida with it to bad it is on the other side of the country, guess i will just have to keep settling for the Sac river which is at sea level only a 2 hour boat ride from the golden gate bridge. Does the salt water really help that much with the performance of the boats never have been in it before (except for a couple of fishing trips in mexico)

I have waterskied in the salt water and it definitely felt more "buoyant". I would imagine that the added buoyancy would translate to an extra MPH or so???:confused:

I wonder if there is enough boat left in the water to make a difference at those speeds???
