obnoxus has a 272 Baja with a stock 454 injected-23 bravo prop
(claims 330 hp )runs 67 mph on the speedo

He just purchased a stock,injected 502 and just finished installing it. With only a few minor details left,he might splash today.

So as you can imagine here is the question.What do think his top speed will be now??


A little hint. I own a Baja 250ES
(older style but almost the same boat) with a carburated 502. Same prop. At present we are almost equal in speed.
(Thats why I put the under claims 330hp)

You will win absolutely nothing,except knowing you are right.If he goes alot faster I'm sure the beer will be on him.
If he stays the same,the beer will be on me:gunner: :laugher:

do you think we'll get the true #'s..they may get tweaked a little! if u know what i mean

 

[obnoxus]

nah,,, thats one thing I never did was tweak #'s,,, what it is , it is !!! He wasnt saying I claim to run 67,,, he said I claim to have only 330HP,,,, which I do,,,, well did !!!

Now if I could only get the damn 502 to run !!!!

 

[Red Stripe]

I'd say 65:laugher: :laugher:

 

[OldMagicfloat]

Todd,I like your way of thinking

 

[Stuchamp]

Might come out of the hole harder, but no prop change, maybe 69 mph, if the prop doesn't wash out !

Have fun guys !

 

[FA18Driver]

Well I bet it will run about as fast as it can....................

 

[obnoxus]

Ok,,, It runs !!! no one guessed yet,,,,, and NO IT WASNT SLOWER !!!!

 

[Stuchamp]

Glad you're back in the water !
So how well did it run, rpm's, etc. ?

You mean we're still playing the game ?
Ok, I'll guess again, 72 mph !

 

[obnoxus]

same prop,,,,5150 rpm on the rev limiter 73 MPH on the speedo, so 6 mph gain,,, gonna try a 25 and see if I can turn it.

I'm a little nervous though,,, I am getting some smoke out of the breather,,, I knew when I put it in it was a used engine, I plan to rebuild this winter,, I just hope it holds together all summer.

I have a Kand N arrestor and breather on it,,, I am going to go back to the factory one for the rest of this season for the fact that the factory arrestor had the valve cover breather plumed right into it so it wont be blowing all over my nice clean motor compartment !!

 

[obnoxus]

Oh,,, and still no porpose no tabs wide open,,,, hull blueprinting works !!!

 

[OldMagicfloat]

is the 73mph with the interior and hatch on or off????? cause my hatch weighs about 150lbs give or take a few

 

[eddie]

Drill out the spedo pick up, that's good for 4 mph or so.......

 

[Red Stripe]

73 on the speedo? So that means I was right with saying 65 on GPS:laugher: :laugher:

 

[greeneyedbeacher]

 

[obnoxus]

you guys are brutal !!!! Well the hatch was off, but I had 2 extra people in the boat so I figure it even out.

Hmmm drill out the speedo,,, I caould have saved myself the trouble of swapping motors.


Something is strange though, either there was something done to this motor, or the 99 25 outlaw I raced had a problem, I talked to the guy after ,,, I had him by 8 MPH !!!

 

[Aggressor Tom]

Speedo 90, radar with current 72, GPS in middle of lake 68. Speed I would tell other boaters, a guzillion mph.

 

[baja29c]

UH OH! I had a piece of wood in my speed pick point and had to drill the wood out. Hope I didn't change the diameter of the pick up point. Does that really change it?

 

[obnoxus]

dont worry,,, Bravos have a stainless tube in them,,, If you opened it up that much you would have problems anyway !!!
