Don't forget the slip if you missing parameters.

502 EFI +415
Whipple 6# +250/220@prop
Roller Cam/Heads +25/+20@prop
Everything else (headers, drive) help the setup last a bit!
Total 645@prop x 2= 1290hp
Baja 36 Outlaw Dry 8300# wet,people&gear 9000+#
No step in the hull.

My amaterish guess 85 MPH

been there done all of that
 

I want to know what your guess would be. One motor is in and the second motor is waiting on the dyno. We will soon know the speed but until then get your calulators out and let's see want you can come up with. The winner to the closest tenth of an mph wins the boat .

NOT

I'm impressed with your homework but
 

you need to do more research on what a top mount will put on a stock 502 then add more hp due to the cam and heads.:fish: :fish: :rolleyes:

I think 85ish is a pretty good guess.

I would say more along the lines of 83-85 gps.......

Allen4 =84.5, GLH 85, Shane 89, Cord 82.5, Tim G 73, Fever Mike 78.5, jt29olhp500's 85.5,

Re: I'm impressed with your homework but
 

I told you I'm an amateur when it comes to engines most of those words are chinese to me!!!I don't know sh!t just using what I got.:D :D :D Let us know how fast!

208 MPH! Watch out Callan!:p :p ;) ;) I would say 89. Good luck.:)

Re: Re: I'm impressed with your homework but
 

GLH I hear ya and understand ya:) I'll post as soon as I know.

Here's a formula that may be of use to some of us sometime into the future

sq root of new hp / sq root of old hp x old speed = new speed:rolleyes:

My dealer up here just did one. As I recall, he was in the low 80's. I'm guessing those motors were around 800hp.

Speed
 

I'd say 73. Yep 73.
I've never seen a brand B pull more than 75.:D

Probably gonna need those 30's. Doub't if she'll pull the 32's.

Good luck, and remember... BOAT means Break Out Another Thousand.:eek: :eek:

My guess: 84-87

PBM tested one with 575's,
ran like.......... 82.
Your buddies boats running
more boost, should be worth
a couple of ticks.
my .02

Not quite enough info, but I'd take a stab at it and say somewhere in the mid 84.5 ? Those 5s & 10s are hard to come by.

RJ

SOOOOOOOOO Far here's the players
 

So when is this bad mama jama getting wet??

One motor and drive is on the boat,
 

he is waiting for dyno time to dyno one of the motors. The second drive is ready to install. I would say a week and a half at the most. More than likely a week.:drool:

1/4 fuel, plus +/- 400lbs is about 9220#

I'm going with 79mph

82 maybe 83 tops.

Go to bed Daddy:D

I am going to say 78-80 depending on temperature.

84 and chine walking, get some boxes on it and lift the x dim.

Sorry gang I forgot to tell ya he went with
 

one inch shorties:eureka:

Picture of the first engine in
 

:crazy:

I have a bud that put the 2 inch shorty on his 25 outlaw, single 502 built with blower about 750hp picked up 4mph, next the box go's on. He's going 87 mph and it feel's like 200 in that thing.

hey Mike, didnt the one at Lake Murray do 80 to 81? It had 500's and stand off boxes. Then they changed to a couple of 800sc's. Do you know who I'm talking about?

yes i do
 

I can't remember what he told us but I thought it was in the low 90s but that was when he had bravos and was breaking them left and right. Now i think he has speedmasters on it. 3 or 4?? don't know too much on speedmasters. out of my range$$$$

What's this .5 crap your either on the bus or off the bus, sounds like kind of pregnant. Commit to a whole number... .5 that's so gay.:D:D:D

When are the results coming??? Big money on this in Vegas yah know.

I'm gonna go long at 88 mph

82 mph. 1/4 tank & 2 peeps. $hitter empty and 1-1/2 ft. Chop.:p

Hey Mike, the boat on Murray is Jeff Acres. He is in the low 90's with 2 Tyler Blower Motors and #3'S. With 500hp's and Stand Off Boxes he was 77-78.

I am going to guess 82-83 on your buddys boat, hope his drives hold up. Jeff broke 5 or 6 Bravos and a couple broke while just cruzn.

Jan

So where do we stand ? How long before we know ?

80 even!

79 - 80

I say 82.2 cause my GPS never stops on an even number. Rag's
