What are the top speeds on the 38 fastech's with 500's?

I have the same setup in a 2000 no ITS setup though.

Best I've seen 75mph

Its for sale if you are looking.

I'm looking a ~84 mph with 645 H.P., extension boxes, XR's with nosecones, unlabbed 28 bravos turning in @ 5400 rpm on a loaded Poker Run Special.

Atomic Sonic,

By the way ... if you end up with Hot Water's boat - towing a 382 from California to N.C. is a bear!!! Take a deisel dually!

My 2000 is loaded like Troutly's - genset, A/C, hot water, etc. With 600 Volvos, I've seen 78.7 mph on GPS.

I get about 80MPh with my 2001 382 with HP500EFI's and extension boxes running 28 labbed props. Then I turn on my GPS and I'm seeing about 77 in the salt. Stupid GPS.....gotta get that thing fixed!

Sounds good to me but it will be next season before I really get to try her out.

Nort,

I think I saw a picture of you airing out the 382 bigtime on the SCOPE website. Isn't the accuracy of the GPS affected by the vertical trajectory of the object in motion relative to the horizontal distance travelled in relation to the motion of the multiple satellites orbiting about a moving sphere? No wonder your GPS is off by 3 mph! Is that running with or against the current?
Did you start with unlabbed 28's and if so, who labbed them and what changes in speed/rpm did you see after labbing?
Are you spinning them in or out?
