I think a performance motor would last longer than a fishin motor, at the least be equal. What decreases the hours to rebuild is the RPMs it's spun too.

I see no way of keeping a performance motor spinning only 6500 though :0

Hydrovector, what prop gave you the 93mph?

How does your boat react when you let off?

Does it feel like your riding on the gearcase or do you have boat in the water?

Thanks

My Pal Chuck hit a BIG number this past weekend.

117 (short run) at 7500 rpm with 4 Blade 15 x 32 Merc CLEAPer, motor at 3/4" UP...I was surprised that Big Prop would run that good. The tattle tail on the Gaf is pinned at 120 :)

We have yet to try a 32 or 30 Merc Cleaver on it yet.

Not bad considering this guy just got this boat 1 month ago. He is learning very quick.

Thats awesome! I knew that 2.5 had lots of power when I took it for a blast. He must be getting a lot of time seat time.

Tell him I said hey and we should try and get together early spring to blow out the cobwebs.

What was the est. HP of that engine anyways?

I watched David Carver drive this one to a run on radar of 139.9 in the quarter at a ODBA race in Plymouth NC in Sept 2001.

Carvers numbers were 28 pitch Lightning ET, 1:78 gear and 10,500 RPM. About 10% slip.

At the start, Marty got out on him about 2 lengths, at about 1000', Carver went by very quickly.

The radar guys got Marty at 132 on the same run.

It was the fastest runs I have ever seen in the quarter for the ODBA guys.

ER :)

ER, what was the ET on that 139.9 pass?

Depends on how you do it.

ODBA style of timing, Carver ran around 9.0 to 9.1 seconds.

Never seen him run IHBA style, but usually there way of timing results in about a 1.0 to 1.2 second quicker ET.

That would make Carver in the 7.8 to 8.0 range.

ODBA starts much like NHRA does, almost from a standstill.

IHBA (and all the bracket clubs I am aware of) have a 100' or so run to get going before the timers start.

By the time Carver or Marty goes 100', they are probably running 70 mph or so, so that is why the big difference in times.

Not that one is better than the other, just different strokes for different folks ya know.

LOL

ER :)

Even so. A 140 in this kind of time and distance takes some cahoonas.

You got that right.

Zero to 140 in 9 seconds,........... MAX stones are required.

Carver was pretty much "on the edge" on every pass he made that day. That was his second one. On his first run, he said it turned 10,800 rpm's, but the radar guys didnt get him.

He was very disapointed cause he was sure the first pass was over 140, but we will never know.

2 passes later, he blew the motor hard enough to knock 2 injectors off the fuel rail causing a small fire. Other than some motor wiring and a melted cowl, the boat was ok......a new longblock was the biggest repair.

Carver is through with racing now, but for about 3 years was at a lot of events and the last two years he ran, he was one tough cookie.
