28 Pantera at Shogren.....
 

http://www.chicagofountain.com/prode...d=284&catid=6#

Cool boat set up. Somewhere along the line someone changed a pulley or de-tuned? It's currently only making 3lbs of boost. Curious if anyone knows the scoop on the motor, or if there is an issue.

I look at that boat everyday. I wonder how much $$$ it would take to convert to a pleasure set-up?

Maybe they de-tuned it to take it easy on the bravo?

That boat is mint. I was on it in the showroom last week and it is spectacular!!!

I can vouch for the boat and Scott Shogren. It is a nice boat and good deal. Scott has personally driven it at over 90.

It is currently turning a 34P.

socalstone, I guess you got the # you needed

Hey 'stone did you buy it? If Scott had been willing to work a trade on a race car, I could have answered that question for you based on first hand knowlege! :D

I talked to Scott about 3 wks ago regarding that boat. I love that one. I wouldn't change a thing. He was allowing me 7 for my trade. I've already been approved but, was hoping to get better interest rates thru my bank. I've been waiting to close on my house to see where I'm at finacially otherwise I'd tell you how fast it'll go right now :cool-smiley-011: I also need to put my trailer back together.

I would at least change it so I could throttle it and tab it myself. I don't trust my passengers that much! :D

Me neither.
I was under the impression that the switchs for the tabs could be reversed on the lever, (so they are facing the driver) and not have to use my pinky to operate:D

You may be able to reverse the trim switch in the throttle. If not a new handle is all it would take. Then add a second set of tab switches, and possibly some more gauges on the driver's side to read easier and you're all set.

I have to admit it's a very CLEAN bad-azz boat but just not very practical for my type of boating.

It's a killer boat no doubt. -I'm biased of course because I love that hull.
Thing is, it is supposed to be a 750hp motor and a 94-102?mph boat. I met Scott and Greg last Friday. We test drove the boat and it only ran into the upper 70's and just touched 80 at the end of a good run w/2 people, not much fuel. Started with a 34 pitch but it was only seeing 4800rpms or so. Then switched to a 32 and it was around 5000rpm or maybe a little more. It doesn't seem to be making much boost (gauge said 3lbs) and I'm a little puzzled as to what's up with the motor. That's why I'm asking if anyone knows if someone changed a pulley. My guess is the pulley was changed or there may be an issue?

ps- as always, Jo was a huge help with everything he knew on the boat.
He personally drove it well into the 90's when it was new. So I know it is capable. Just not sure what is holding it back now.

Looking at the huffer looks like a smaller pulley, but I don't know if its a 6 or 8/71 blower. It says in the classifieds that the blower "is set" at 3 psi of boost, which would mean top or bottom pulleys or both. It also depends on the compression ratio of the engine, too high of boost and you won't be able to run pump gas easily, either.

Practicality has never been one of my strong suits...:D I'd rather have a full cabin and better bench seat for passengers, but I haven't found a '03 with 15 hrs for 50k... yet. Either way, I probably can't afford it anyway, and it'll be sold before I can get financially situated.
But I'd like to own a triple digit Pantera someday though. It just seems like 4 of 5 boats you read about in PB mag are triple digit. I just have visions of putting my buddy's 29 Baja with 2x496's to shame. :cool-smiley-011:

Dude, 4 of 5 boats you read about in Powerboat that run over the century also have an extra zero in the price (ahead of the decimal).

I never saw a mph claim but I do remember seeing 750hp in one of their ads. But now none of them are claiming hp. Maybe it made 750hp at 5 or 6 lbs? Either way, 750hp isn't going to crack tripple digits but I would think 90 is possible.

Did you ask Scott or Greg about the pulley(s) and boost?

Just wanted to add that I'd never heard of the century on this boat. Jo drove it a bit over 90, as I recall, and there was speculation that with the addition of the intercooler it should be a bit faster.

I've only heard of one 28 Pantera that runs The Number...

I saw 92-93 MPH consistent with a 31' labbed 4 blade at 5400-5500 RPM on delivery and then a Chiller was installed bumping up the power a bit more.I never ran it with the Chiller. Gary Grimes was the engine builder out of the Atlanta, Ga. area. If I can help answer any questions on this 28' just let me know.

JO

"Runs 95-102 GPS" is what Scott told me when I enquired about the speed.

The wording in the classified ad changed to "set at 3lbs of boost" Friday, after we test drove the boat and saw that it was only running to 80 with the gauge at 3lbs.

It's still a cool boat. I was just dissappointed in the top end.

I think there's a national conspiracy to keep all the big HP Pantera's under 85 mph!

:D

I'll bet Reggie's behind this!

Did Scott have an explanation at all as to why it only ran 80?

I agree killer boat but knowing Jo has ran it 90+ makes you wonder what is going on!

If its 750hp, then it should run about 85 mph. No way its gonna run 95mph with that HP.

Also, a chiller will reduce boost pressures. So if it was orignally set up at 4# and the same pulleys were left on, then 3#'s is reasonable.

Hmmm, Shogren is a Fountain dealer... Reggie must be behind it!

:D

You know, just thinking about it, what are we going to do with all our free time once this boat finally sells!?

Prolly talked about another Pantera... :D

BTW, I'm pretty sure its listed in this months PB Mag on Shogrens page at 750 hp.

Hmmm, no cabin and notched transom. Isn't this basically a F-1 set-up? I would think it should crack 90 with 750hp. But I agree I doubt 95 is there.

It makes sense if the boost was dialed down. I'm sure it is fine. It looks great and I'm sure you'd be happy with it.

I agree about the conspiracy . . . I found a gold chain and hair dye next to my boat one night :D

i enquired about it about a year ago...was told current set up ran 80's, with a pulley change its touched 100

750hp should be mid 80s any day.
So... who has the dyno sheets to prove that's where it is?

Tell them to keep the engine and pay 30.
Then slide a Zul 775na in there for another 30.

According to the customer we built the boat for with the Chiller the motor was closer to 800 HP.I am sure Gary Grimes the engine builder would remember the "real" HP and more important "torque" with this combination.

I only ran 1 prop for 1 hour and that was a 31 labbed 4 blade Bravo 1 and with a full tank of fuel ( 90 gallons on the race set up ) and my customer and I in very hot and humid conditions in the bay 92 - 93 MPH and I recall the prop was down like 200 - 300 RPM from peak RPM - HP. I think the boat certainly with more time and tweaking could of ran 94-95 MPH before the Chiller was installed.It accelerated very strong !!!

Remember this is a much lighter version than a full pleasure 28' set up and the drive height was higher with the notch transom.

I was also interested in this boat, but now I'm starting to have second thoughts on it. Been around enough performance vehicles to get a feeling on a engine that was detuned from its original settings. Almost sounds like it was set back so as to protect something or worse case its to hide something already weak from running that hard. Either way it now has me a little worried. . But I would find it hard to believe that someone like Scott would sell something that was not 100%.Why risk the bad press on something at this level when some of his other sales tickets are in the mid to high 6 figure level. Just had to add my opinion on a much talked about subject.

By the way our black F1-71 race boat with basically the same set up would run back in 2001 - 2002 78-79 MPH on GPS with a stock Mercruiser 500 EFI. With a 525 EFI easily over 80 MPH. Now add a blower motor with an extra 250 - 300 HP and you can see why the low to mid 90s are there with no problem.

If a stock 32 or 34 pitch were run on the boat and the motor is only turning 4800 - 5000 RPM at WOT then you need to put a 30 or 31 labbed 4 blade to get the RPM up in the proper RPM range of 5600-5700 RPM and your speeds and acceleration will increase.

JO

Probably detuned it to protect:

1. the outdrive
2. the salesman on the test run
3. the buyer who might kill himself
4. to keep the engine healthy and reliable

Jo, didn't know it was full race lay up. I remember Fred's 6 pack boat ran about 85 with the same HP.

I'm not doubting what this boat has done, but alot can happen in the years it has been for sale, moving from dealer to dealer. If the drive checks out fine and the engine is solid, w/ correct compression and leakdown, i think you'd be fine.
Nothing different than buying any other used boat.

Wanna know what you got for an engine? just gotta rebuild to know for sure.

Well done! I'm still laughing! :D

Hi Griff,

This boat was a little lighter than Fred's 28' plus the drive was mounted higher with the notch. This boat we rigged complete while Fred's 28' was rigged by the original customer on his own since it was sold as a hull and deck with a 6 man bolster only. Fred's 28' was a 1997 model while this boat was built in late 2002.

Not sure of the HP and torque between the 2 boats but I do recall Fred's boat was a carb. motor while this boat has a blower with Chiller.

Regards,

JO

Jo, do you recall what the boost was back when you drove it?

LOL :D

Funny AND true!!!

Since I've been reading this board I'm always impressed with the feed back. The information is usually on the money. Now if only that guy Geraldo had this kind of feed back he might not of had that awkward moment with Cappones vault.

I do not recall the boost but 3 pounds sounds very low. It has been close to 5 years that I ran the boat.
