Re: HP500carb. and Bravo X
 

Thank you for the info. Need to go to bed now, it`s nearly 2:00 in the night here, but it`s hard to sleep it`s nearly as light as the day!

Best regards from the land of the midnight sun!

Re: HP500carb. and Bravo X
 

Mudball, What were your numbers prior to the swap? Power,Prop,Rpm,ect? Very nice. Thanks, Doug

Re: HP500carb. and Bravo X
 

Before HP500:
Engine: 1999 7.4mpi.
Prop: 24p stock Bravo.
RPM: Don't remember exactly, but around 4600-4700.
Best speed ever was 63 gps. Normally around 61-62.

Kent, How much taller is the 500HP than the 7.4mpi? Doug

Re: HP500carb. and Bravo X
 

The HP500 is taller on the intake, but the exhaust is about the same as the 7.4mpi with the riser spacer, like this pic, after it was pulled...

Re: HP500carb. and Bravo X
 

Wow, that shows the HP500 as 3/4" shorter!!!
Fascinating!
My HP500 intake was taller than the MPI intake. I remember that because I measured everything before the swap to make sure it would fit. I wonder if they are talking about the exhaust risers? I would believe that the exhaust might be a little shorter.

Re: HP500carb. and Bravo X
 

Maybe, on the picture it shows the exhaust ca. 1/3 up on the flame arrestor...

Re: HP500carb. and Bravo X
 

I would have thought the HP was higher. You guys are good! Hydrolift, Do you have the numbers for a carb 7.4L and a 500HP EFI? My 7.4L is tight in there, in every way. Thanks Doug

Havent got any data on the carb 7,4L
