Will a new whipple charger fit a 27' Fountain without back seat modifications? I just purchased a 1995 Fever, and would like to upgrade the 502 MPI with a Whipple. I have the need for some speed and the Reggie papers of 71 MPH are not going to do it for me.
Also, Who is Dustin? and how do I reach him?

Thanks,
Scott

Scott,
The back seat will have to be cut for the pulley to clear with a Whipple, I had one and sold it because of that and went with a Procharger instead, no clearance issues, gained 15 mph and have run it for two years with no problems. The Whipple is a great kit also, so as long as they are both set up properly either one is a good choice in my opinion!

Scott McKay, Dustin Whipple is his name.
That should tell the story. He is the person you have to talk to when you need tech support / advise.

hotlavey, how is the install time fram looking. Do you have the equipment yet? Keep us posted on the progress.

The install will be taking place next week by a former employee of Whipples who is now located at Lake Havasu. He has 20 years experience so I am very comfortable with him. Dustin recommends him highly. I'll keep you posted on the progress and results. Right now I'm trying to locate a loaner 30" & a 31" Bravo to put on when I run it. I ran a 26" tuned but that's going to be too small now. I think Lavey will loan me one or the other, I hope.

Tom

Cool, looks like you will be on the water pretty soon. Sounds like you have a great resource for the install.
Tha should be a lot of fun!

Rock, Taking the boat to him this Monday. The blower is there waiting to be installed. He insists on doing a "in-the-water" test as soon as he is done which is a very good thing. He feels the job will take about a week so maybe by the 12th of April I'll be able to give you some first hand results.

Tom

Man, I bet you are getting excited. I wish my big boat would go that fast orrrr correction, I wish I had enough money to make my boat go that fast. Maybe in a year or 2 I can either upgrade or build a 572 blown monster and get this 28 footer to go 100.
I think an in water test is the right way. When I did mine I spent a lot of time dialing it in and even had to send the ECU back to get it reprogrammed. Your guy hopefully can just reprogram it fast and try it again until it's right.

Rock, from what Bernie tells me(he's the one doing the install) the ECU has to be sent to Whipple for the reprogramming. That's why it takes one week for the complete install. You're right, I am getting excited and anxious to get this puppy in the water with all the mods. I spoke with Jeff yesterday at the Anaheim Boat Show(He's one of the owners of Laveycraft) and he has a 30" bravo to loan me for a trial run.
I'm ready!!!

Tom

Remember, if you have some extra cash, you don't own a boat!

Rockie, The boat is now at Havasu with Bernie. I had a chance to touch the new blower as it is ready to be installed. Pretty neat. The first thing he did while I was there was to pull out the ECU and UPS it to Whipple. Let the games begin!

Tom

I ran the Whipple at Havasu yesterday(Monday). It ran 83-85 at 4750 so the 30" is a little too large. Lavey is loaning me a 28 to try next. Mid-range on this puppy is fantastic, even with the 30". It jumped from 50 to 80 mph in a heart beat- At 80 I was turning4200-cruising speed- Amazing. It will be interesting to compare the speed/rpm's between the two props.

All right. That is the fun part.
Actually you are probably right on with the 30-prop. If you lab finish it, you will be right around 5100 rpm's. Your slip #'s are pretty good too. Assuming your tach is right you are running about 7% slip. Try the 28 and see how it does. I have tried both and the 30 is a little faster, but planing and acceleration is better with the 28. How much boost are you running?
Glad to hear it's running good.

Rock,

I'm running about 6lbs boost according to Bernie. To be honest, I didn't look at the boost gauge when I was running it. I was too stoked on the feel of the boat and the speed/rpm's. Duh! I should have taken a peek at it. I'll certainly check it next time as the first time excitement has now subsided somewhat. What a kick!
My prop guy said he could probably get another 250 RPM's out of the prop but that I should give the 28 a try, which I will. Where I run the boat, top speed really isn't as important as mid range. I'm on the Parker strip most of the time, with a visit to Havasu on occasion. No poker runs except at Lake Mead at our yearly regatta.

Tom

hotlavey -

I finally got my boat back from a very well known performance shop (referred to as XYZ marine) after having a Whipplecharger installed on my 271 Formula Fastech 502MPI. I took it to them because I wanted it done right. Whipple implies that this is a weekend job which we all know is a bunch of BS for most of us. For an expert, maybe it should take say...4-5 days at most. XYZ promised me a one week turn-around. THEY HAD MY BOAT FOR 5 #*&#@*% WEEKS!!!!!!! Basically, from the time they had my boat and my cc#, I felt I was getting screwed. They did redo the heads so let's give them an extra week for that. I know they had some complications too with a leaky head gasket after the first assembly attempt. Everything seems to be running right so I guess the did it right.

Now the good part. I am still playing with propellers but even with my stock B1 26P, the acceleration is awesome! Throttle-up propellers is sending me a Hydromotive P5 26P to try (Julie at TU rocks!). Looking forward to see how much my top end has improved.

I usually have the attitude that "if you want it done right, do it yourself" but if I had to do it all over again, I would endure the frustration of 5 weeks without my boat, and numerous unreturned phone and let someone experienced do it (not necessarily XYZ). I think Whipple is an awesome system if done right the first time....or can be a total nightmare if not.

Grog,

Keep me posted on your prop testing. I'm in the middle of doing that now. It only took a week for Bernie(retired Whipple person) to do my install, complete with gauges, water and fuel bypass, etc. Ran flawlessly the first time out, I was just propped wrong.
Keep in touch.

Tom

hotlavey: Your quoted speed and RPM numbers are almost exactly what you would expect with the prop change, but you should be able to spin the 30 a lot higher. You said 81 mph before and I would think you should be 95+mph now. If the midrange acceleration is good but you can't get past 4750 with the Bravo 30, maybe something else is holding you back. I trust that you are checking fuel pressure and plugs. Good luck, let us know!

Tom

Tom

Fuel pressure was right on as was water temp. I did not have my GPS on the boat when I did this first run so I am relying on the boat speedo which indicated somewhere between 83-85(bouncing). When I GPS'd at 81 prior to the Whipple I really air'd the boat out and was doing a little chine-walking and porpoising. This last run was done a little more safely and conservatively. Much more comfortable. I was told going in that the 30 may be a little tall and the 28 would be the one- I think that will be correct. We will soon find out.

Tom

If you have spare cash, you don't own a boat!

Grog, Have got a 26p five blade labbed hydro prop for sale e-mail me at [email protected] for details

Tom,

Just returned from the River at Parker,Az. There was no wind, no boats, and mirror smooth water and a temp. of 80. I ran my 30" re-worked prop. GPS'd at 84 at 5000. I was hoping for more. I had 3 people in the boat, 1/4 tank of fuel, and a relatively empty ice-chest. It was still climbing, probably could have run 85. I was running with one tab down a touch to level the boat as it does torque down on the left side a little. Speedo(Gaffrig) indicated 90- boy, are those things inaccurate.
Actually, I guess the speed isn't bad for a 29' deep-v, but I will try a 28' next time out, just for fun. Mid-range is awesome, even with the 30".

Hotlavey -

85 mph on a 29' deep V sounds pretty impressive.

My first cut at a new prop was a Hydromotive P5, 26P which got me to 71 gps at 5250 rpm. (11 mph increase from pre-Whipple). I traded it in for a 27P and lost about 2 mph at 5000 rpm. The slip numbers went up from 10% to 12%. I am sold on the 5-blade prop. The acceleration and hole shot are great. I may be sacrificing 1-2 mph top end but overall performance makes up for it.
Throttle-up tells me that the new P5X will be out around the third week of May. It is supposed to run like a labbed Bravo. I am anxious to try it out.

Matt and Julie.....CAN YOU HEAR ME?!?!? VERY VERY VERY ANXIOUS!!!!!!!!! :)

I've heard about the 5 blade but holy smoke are those puppies expensive! I am really not interested in hole shots as my Bravo XZ would jump overboard if I nailed the throttle now. Mid-range and up is what I like and the Bravo 4 blade works fine, even tho the 5 may be a little better mid-range. Not really sure the amount of improved performance would justify the cost. Besides, if my wife found out what I have been spending on the boat lately I'd be talking a few octives higher and sleeping with the Whipple.

Hot Lavey,
Sounds like your getting her dialed in nicely. You are hooking up really well with that boat. We just got back from the Heatwave and I was spinning a stock 30 on our 28 Heat to 5600 and got got a GPS 85.2 on short blast. This hull is pretty notorious for high slip numbers though; not nearly as efficient as your Lavey. I will say though, it feels like it’s on tracks. Rock solid at those speeds.

I have a P5-X coming from Throttle Up that I’m hoping will remedy some of this slippage. I’m shouting also Grog :D
I think my particular boat is a prime candidate for this prop. I’ll let you know how it works out if I get it in time for a Memorial Day trip to Mead. It probably won’t be enough prop (27 pitch) because I actually bought it for our higher elevations here locally. It should still be a good indicator of how it performs overall though. If it works as well as I hope, I’ll probably sell my 28 and 30 Bravo and buy a 29 P5-X for our lower elevation trips.

Did they check your tach when setting it up? It seems most tachs read about 150-200 high. If that is the case you may be only turning 4850 or so and leaving a lot of torque load on the prop slowing it down a bit. A stock 28 may get you up around 5300 and really loosen the hull up quite a bit and she should run really good.
Sounds like your having a blast!! Good luck with all and be careful. It may not be nearly as fast as some of these rockets but it still feels fast to me :D
Dave

Dave, you must be running some major power to spin a stock 30 prop 5600. I'll be really interested in your results at Mead in a few weeks. Hope you get some major increases.
I'll be at Mead myself for the Lavey Regatta in Sept. I hear water levels there are not so good.
What is causing your high slip numbers and how do you determine that? They don't seem to be affecting your top end- 85 on a short blast is not too shabby. It took me some time to get to 84.
You brought up a good point re: the accuracy of the tach. I don't think it's ever been calibrated. I'll have to research that and see where that can be done.
I may be interested in your 28 if you decide to sell it. Keep me posted on that as well as your test on the 5 blade.
You're correct about the other "rockets". There is some major speed going on nowadays. 80's are not slow but comparred to some it's crawling. However, I still get bugs on my glasses so I know I'm moving.
Where do you do your boating? You mentioned high altitude and Mead, just wondering.
I hope you're having as much fun as I am trying to work out all these little puzzles. Gives me an excuse to get back on the water a lot, but damn, I'm blowing through a ton of fuel.
Good hearing from you again, and good luck with the P5.
Be careful and keep in touch.

Tom

Heck Tom,
It’s easy to spin them that high when they slip that bad D: D: D:
Really though, I run a custom built ProCharged 548. I think the slip is from the very high X dimension in combination with the stepped hull.
Yes the water level is low at Mead but as long as the ramps are in good shape, there’s still a ton of lake.
We are from the Northern Utah region where our local lakes range from 4500-6500 feet. We frequent Powell and Mead for long weekends and such and then do most of our boating locally. Havasu once or twice a year.
I don’t know about calibrating your tach but you can have your mechanic check it with his scan tool I believe.
I’ll keep you posted on the P5-X results.
Your right, it is fun but not too economical…however, since the supercharger I haven’t noticed any big increase in fuel usage unless I’m running real hard (obviously). Actually it seems when cruising for long rides that it actually is more efficient with the bigger props ;o)
Keep us posted on you results as well,
Dave

Dave, a quick question. Why did you choose a P5X over a Quad 4? I noticed on the posted race results that most of the top boats were running Quad4's. Just wondering.
Tom

The Q4 is probably a tad bit faster if you don't have a slip problem. A good friend of mine tried a P5-X on his 28 Nordic with outstanding results.
He also tried a Q4-X with very poor results. It's all about the boat you put it on I suppose. There's only one way to tell...TESTING;)

Re: Whipple
 

Now that I have the Whipple dialed in I am thinking about selling my complete 2002 EFI System. It has the mono-blade setup from ASM and the Teague Flame Arrestor. It has 68 hours on it. Not sure what the value is- anyone???

Re: Whipple
 

NordicHeat, You said that the P5-X produced great results on your friends Heat. How muck did he gain.
We just installed a Procharger on my friends 28 Heat non-step and it is running good, but the slip is about 17%-18% with a 26 & 28 Bravo1 lab. We are hitting 71, but I think we are running a little slower than we should. I'm also running about 20% slip, but I'm running 80mph and was thinking about trying a 5 blade of some sort to see how it does.

Re: Whipple
 

Rockie,
The numbers on your friends Heat sound about right. Pre-supercharger (N.A. 540c.i. ~575 hp) I could turn a 26 to ~5500 and run 72-73 and the 28 would run the same at 5100-5200.

The testing on my buddies Heat were close on speed runs but the handling, planning and most of all, the cruise performance were the deciding factors for me.
His testing was based on back to back runs with my personal 28 Bravo that was just balanced and trued by Bronson/Hill (not labbed) and a 27 P5-X.
The hole shot is said to feel like a Bravo 3 with no slip at all with the 5 blade. Also with the P5-X the boat could plane down to 20 mph where as the 28 cannot hold a plane under 27 mph. The cruise numbers were the big factor for me. With the 28 I can barely maintain 41 mph at 3500 rpm. The 27 P5-X would run low 50’s at the same 3500 rpm. This is where I spend most of my time when cruising up and down Powell or any other long runs.
The WOT runs he made were very close (for reference, his power is approximately 600 hp naturally aspirated and his hull is stepped) He could spin the 28 Bravo to 5150 and 72.6. The 27 P5-X spun to 5050 and 72.4. This was on about one foot of chop. The interesting part was he tested once again back to back on glass water and the 28 Bravo would only spin to 4900 and barely 69 mph, the P5-X ran the exact same numbers it did on the chop, 5050 and 72.4. This just tells me it carries the boat much, much better.

I ordered a 27 for me. This is a replacement for the 28 used above. It will be my high altitude prop as was my 28. At 5000 feet I turned my 28 5600 rpm and 81 mph consistently on GPS. So I’m very anxious to give the 27 P5-X a whirl to 5600 rpm at my home elevations. If it works out as well as I think it will, I will sell my 28 and 30 and then buy me a 29 P5-X for my Mead and Havasu trips :o)

Sorry for the long winded response…
I’ll keep you posted when I get it.
Dave :)

Re: Whipple
 

Dave, don't forget that I'm in the market for a 28. What work has been done on it? It's still a true 28 other then what Bronson did?

Re: Whipple
 

Thanks for all the info Dave. It sounds like the Heat is about right where it should be.
I really like the idea of cruising 50 at 3500rpm though. That would come in real handy when I make the truck down to LOTO. I might have to try one.

Re: Whipple
 

Tom,
the 28 is just what B/H calls ProTuned. It's just balanced, trued and polished.
It turns ~350 rpm more than my 30. I'll let you know.
Dave

Re: Whipple
 

Dave, I'll be waiting to hear from you re: the 28. I won't be going out until after Mem. day and I assume you'll know by then what you will do. In the mean time I'll be installing a Livorsi GPS Speedo as I am really tired of trying to remember to bring the hand held with me. My Gaffrig speedo was way off anyway so---
Have fun

Tom

Re: Whipple
 

Sounds good Tom,
I hoping that the 5 blade gets here by Memorial Day.
Dave

Re: Whipple
 

Dave, Just a short note to let you know that I found a 28 here at home so I won't be needing yours. Hope your new prop works well- have a great time this week-end.
Be safe-

Tom

Re: Whipple
 

S--- happens,

I blew a head gasket and hydraulic'd the engine. Had water in 4 cylinders. Not sure if I bent anything yet but damn, sure wish I had listened to the one's that suggested I also do the gaskets when I did the Whipple. My stupidity cost me an extra couple of grand, at least.
What was that about a hole in the water?

Re: Whipple
 

OUCH!!!! So sorry to hear that. Just when you were starting to have some fun.

Re: Whipple
 

Grog, I was warned by more then one person about the gaskets. Trying to save a few bucks cost me a lot more. The embarassing part was being towed back to the marina(two hours away) by my friend in his new 17'Tahoe fishing boat, complete with the electric bow motor. All the good stuff will be put in now, at least as far as the heads and valves and gaskets are concerned. The bottom end was fine so it will be left as is. "I'll be back".

Tom

Re: Whipple
 

Sorry to hear about the misfortune hotlavey!
Did you already pull it apart to find out that the bottom is still good. If so you might as well change bearings, although you don't have many hours on it. It sounds like you will be back on the water pretty soon. If you are like me and it breaks, I just pull it all apart and get after it so I can get back on the water ASAP. I really thought the gaskets would last longer than that, but I tried to warn you. OH well, I did the same thing. It just always happens at the most inconvenient time. Keep us! posted
