Wouldn't it depend how much boost you are running?

[SHAKEN Not Stirred]

Well.......
Ask Dustin !!!!!
dustin@whipplesuperchargers.com
I would say.......680 would be close, with about 6-7 lbs boost.....
You would need quite a bit of boost to make 750....and a few more cubic inches.

hey badass do you know the difference between a 500hp non blown big block and a 650hp non blown big block.answer nothing but some cubic inches.do you know the difference between a 650hp big block non blown and a 650hp blown big block answer a shit load of insurnace money.blower=ins money.

I now im just finding this out.i was thinking that a insurance company cant tell the differance between a non blown motor on hp but once the blower is installed there goes the insurance rates.any suggestions ?

[boatnam2]

badass this just comes down to how much power and speed you want and what is it worth to you.i think that with a non blown application you can fudge a little on the numbers and get a pretty good insurance rate.if you put the blower on insurance rates sky rocket with only a few companies even writing policy's cant realy fudge because they look at the blower like the devil and if something happens and they see the devil it could get ugly.

[DryHeatOnly]

What kinda drive are you gonna put behind that power?

i was going with a xr drive.

Well,
Here is the magic info.....
1-Insurance companies will look for any reason to "NOT" pay a claim, so don't lie.
2-The HP matters more, not if it's blown.
3-The magic number for speed is 80 MPH, go over....you pay.
4-They are savy these days...They can do the math. 750 HP in a 26' cat will do over 80 MPH.....and they know it.
5-Only a few will insure you over 80. I am now with Markel....I went from 420 HP/62 MPH, to 620 HP/75 MPH, then to 850 HP/85 MPH. $$ went from $700, to $900, to $ 2,000 a year......
You gotta pay for speed....

Depending on the boat and your driving........The XR may last a year, or a day.

[BADASS38CHEVY]

what is a good rated hp injected motor that is not blown that will give me maximium speed in a lavey deck boat that is turn key and reliable ?

[boatnam2]

that is true to a point sns but if you got built a 542 big block 9:1 and you making 500hp and i built a 542 big block but used a different cam and compression and im making 650 horse and we sit the motors side by side there is no one that could walk up and say there is anything that would tell them which one is making 150 more hp.put a blower on one of them and forget about it horse power can change 100 to 200 hp with just the change of a blower pulley like you said they are not dummies and realize this.

[DryHeatOnly]

Not to sound like a puss, but how fast do you need or want to go in a deck boat? I'd be more concerned with getting good low end torque and mid range for when the boat is loaded with peeps and gear (IMO).

[SHAKEN Not Stirred]

Paul Pfaff 700 EFI......
Best non-blown bang for the buck.......
When Merc comes out with 700 HP or so, it will cost a bunch more.
Call Steve at Pfaff.....714-894-7574

:D

[boatnam2]

badass i did not mean to get you to think about other options but i though i could sheed some light on a few options.i was paying 2400 hundred dollars a year for 620 hp in the same deck boat you are buying which is really more like 590 at the prop.i willing to fudge on 90hp on paper to save some bucks most dont and that is fine also.i hope if i ever need to use my insurance it will be for left and they try and prove i was lying about 90hp.

[SHAKEN Not Stirred]

Sammy (DHO) may be right.......Maybe a Merc 525 would be OK.
But you'll pay about the same or less for a Pfaff 700.
You are going to take it up the B*TT anyway cause that boat is goin' to do over 80 the way your goin'.
CJG
:D

[boatnam2]

good luck with what ever you do badass.the new ***boat mag has a lavey with a 525 that went 72 or so. you would not be lying about speed and power it is in writing in a article by professionals and your insurance will only be 750 bucks a year on actual value of 115k.if you choose to add 150 more hp and around 7 mph its going to cost you a extra 1500 to 1700 a year.

Not to sound like a puss, but how fast do you need or want to go in a deck boat? I'd be more concerned with getting good low end torque and mid range for when the boat is loaded with peeps and gear (IMO).8 people in the boat ,100 gals of fuel,boat weighs 4900lbs.and want to hit 85 with these conditions.what horse power is needed ?

[boatnam2]

probably 700 closer to 750.i went 77mph 100 gallons of gas and 4 people in really flat water.do a search on devin wozencraft at farmers that is who i have used for 7 years.if you cant find his number i will get it for you tommorow.i use alternative ins agency in corona.i have pretty much the same as you 100/300 10k med pay 110kcv.with progressive if you pay in full they give you a 10%break.

[jackpunx]

I have/had an HP500 carb motor with Dart pro allum heads, 3.3 whipple, Cam and a 1050 dominator carb, I ran about 750 (no dyno on my motor but GT built it and works with Dustin at whipple ant they have dynod other motors with same application) they said I was pushing about 750 with all that stuff..I was running about 6-7 lbs of boost. I bumped it up to about 9 (running AV gas)and they said that should put me around 800hp. I ran that for 160 hrs with 0 problems. I also have an XR drive that I service every 25hrs with 0 problems. (although I have a smaller lighter boat).
I have talked to Keith in length at conquest and they are building quad rotor 540's that are pushing 1100hp with the worx (bravo one) drives.. 0 issues.
So it can be done.. pretty much turn key power..
Ins will be an issue.. good luck on that part :smile:

[NashvilleBound]

A friend of mine has the HP500EFI with the WhippleCharger on it..along with the XR. He pays @$750 a year cuz he added the charger after 100hrs. If something happens and they see its got the WhippleCharger the claim will most likely be denied. The XR is a great drive...the key to its life is a good aftermarket top cap with a shower and easy on/off the throttle. It has worked for my friend for several years....along with regular service. Oil is cheap. It was my understanding that motor made @750hp and @825 fp torque...with 6lbs of boost. Hope this helps...and I hope my memory is accurate with those numbers. :hammerhea

jackpunx,
Would you recommend servicing an xr drive every 25 hours if I am running a 525 stock?

[jackpunx]

jackpunx,

I'll tell you what I do... I change my oil, change my impeller, check water separator and service the drive every 25hrs. I have not had any issues yet. I have caught some bad impellers before they got really bad which is a good thing.. I think it’s a great idea just to have a routine so that you are always looking for symptoms to hopefully catch them before they become serious problems.
Hope that helps.. I don’t really know how to make recommendations on new stock motors.. I have been told that 50hrs is when you service a stock motor. I drive mine pretty hard.. so.. I would tend to error on the side of caution.

8 people in the boat ,100 gals of fuel,boat weighs 4900lbs.and want to hit 85 with these conditions.what horse power is needed ?
I would think alot! Unless you had 2 engines.

[BADASS38CHEVY]

so the whipple should do it ,just dont run alot of boost.

[jackpunx]

I would think alot! Unless you had 2 engines.
Badblown 572 can hold that many people and that much gas and go at least 100.. in a 25' cat with about 1000k hp
(I dont think he would ever go that fast with someone in the bow.. but I know the boat would do it)

[jackpunx]

so the whipple should do it ,just dont run alot of boost.
with out heads and cam.. your looking at 700hp max at 6 lbs boost

I ran mine for about 150hrs on 6-7 and bumped it to 9 for about 40hrs.. when they took it appart.. it was all good on the inside.. My builder said I should be able to run about 300 before re freash

was 300 hours after he refreshed or you could have gone 300 hrs from the begining ?

But isn't that lavey even bigger and heavier? 1000k hp (1,000,000 = 1000k) is a lot though! ;)

[jackpunx]

I could have gone 300hrs from the begining.. but its appart now at 190 and the internals look fine

[jackpunx]

1000hp is alot.. and bravo drives dont really like it much.. but I hear the worx drive can handle it. Im thinking with 750-800 he can get his 85mph..

[boatnam2]

bad ass since i have the same boat as you i can tell you that your spending alot of money to go 85 or 90 but you will find out real quick besides you everyone is sitting sideways and there really not having much fun and there scared to death.so your really spending all the money to go fast when your buy yourself,maybe that will be alot and it is worth it to you.

[SHAKEN Not Stirred]

how many hours will you get with 6-7 lbs boost ?and how many hours with 10 lbs boost ?
If you don't run it hard all the time and change the oil & filter every 20 hours, you should be able to make it to 400 hours before a refresh. At about 200 hours, you'll need to replace the valvetrain. I am running 6-7 lbs of boost and just hit 60 hrs after one season.
My motor dynoed at 996 HP and 900 ft lbs of torque at with 9 lbs of boost, but the guy's at Pfaff reccomended keeping it down around 6-7 lbs to help it live for quite a few years. I'm happy with the 850 HP.....
Also....My Markel policy is written through "Alternative Insurance Agency", call MIke at 951-280-9999. I spent way too much time shopping around and these guys came up with the best policy.
Good luck.

I tend to agree.......
I don't/can't run 85 MPH for very long......Not everyone is happy at that speed in a 25-27' boat, even if it is a Cat.
However........No one has ever told me ... "I wish my boat had less horsepower !!!"....
You don't have very much wind protection in a deck boat, although speed runs with your buddy are cool.....
I'm still thinking a 700 HP EFI motor may do the trick, but remember, you can't just throw a blower on it later.

I'm thinking the same thing. My friend's uncle had a big horsepower Phaff motor (700-800hp?? I'm not sure) on his Conquest. It was an awesome boat and motor. Fast too (upper 80's) but I was told that it was scary as a passenger to go that fast all exposed like that.
BTW-The Conquest was sold and the motor is now in his 28' Daytona ;)

[phebus]

For a deckboat, be happy with moderate speed and reduced insurance rates, and spend your money on a killer stereo and billet bling. That's where the party is. :D

boatnan2,the reason for the big hps is for when im mainly with myself and a couple of people .i have been in boats that do 87-90 and that is fast enough for me .my wife wont like going that fast so it wont be happening to much.its good to get on it every now and then.when i went on water test with kevin at lavey top speed wasnt fast enough for me and that was with the 525hp.

[boatnam2]

believe me i hear what your saying badass.i had a 100+cat for 5 years so it is hard to go back to a 75mph cat that is why i got the deck boat.i know when i took it out i wish it had more throttle at times but im ready to give up mph to save money and headaches when you go away for the week and your shit breaks.i guess if money was not a problem i would do what your doing.i say spend the money and do it right the first time.
