How fast will she go???? (My buddy's boat)
 
1 Attachment(s)
Boat 2000 36 Outlaw
Had:
Stock 502's EFIs with Stainless Marine Headers
1.5 Bravo ones with labbed by Merc Bravo 1 24 pitch
Speed- 67 to 69

Now:
Top Mount Whipples with 6 lbs.
502s had new hyd. roller cams (builder will not give out specs).
Merlin steel heads.
Imco SC Extreme drives 1.5

What would be the new hp and the new speed. I know their are some holes not filled to determine the speed. But give it a stab!
Props to be determined. Probably 30 to 32.

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

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

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.......

MIKEHTMSR24 04-02-2003 06:34 PM

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