Whipple on 496 HO

[SecondTake]

Any one have user feedback on the whipple 496 ho kit? How does it perform, reliability, idle. Are all the whipple claims true?

[carreraboat]

have 2 freinds with whipples one on a cat one on a 28 nordic both broke i would maybe wait a little bit! i think maybe try and put some hours on before you put it on maybe that will help do some reasearch. on the other side they made a hugggggeee difference in the the way they both ran

[Infomaniac]

I am curious about what broke myself.

[carreraboat]

valves on one pistons on the other both systems were profesionaly installed at 2 different shops in 2 different parts of the country the guys are bummed

Has any one said if they think the source is the whipple or something in the engine? The 496 is less than tried and true yet from what I hear.
I need some extra horses to get a 40 hustler up and going better. Has stock 496 ho's.

That is a good question i was wandering that my self i also have a freind that has the 496 in a avlanche with a whipple and totaly beats the crap out of it been to cali numerous times pullin a jeep on a flat bed never had one lick of trouble. the guy in the cat was one of the first who put a charger on his 496 and had a bunch of hours on his so i dont know.i havent heard of problems with the procharger. I think you are do the right thing by asking a ton of questions, big investment. I see sometimes dustin whipple post on here maybe he could shed some light on the subject. I never seen anyone from procharger post on here though there are some guys running there product

I have one on a 502 MAG and its been great, no problems, except one broken drive. Im now looking into a quad rotor on my 600 cube for my new cat. I've heard of nothing but nightmares with prochargers, but then again, the ones i've seen werent just a stock motor with the charger slapped on, they were all alot more 'played with'.

[Whipple Charged]

To clear things up, the one with a lot of hours was running approx. 8-9psi, by no means a "stock" configuration. From what I've heard, the second setup had a fuel related problem which was diagnosed.
Many have run the crap out of them with no problems. The Procharger is by no means more reliable, they do nothing to the ECU, run a map sensor bleed system so the stock ECU never sees the proper pressure and run the injectors way further then what they're intended for. You can't run 70-80psi in the stock injectors with any control, there wide open and can vary greatly.
Were working on a 725+HP package that will go internally into the engine.
Thanks,
Dustin

carreraboat,
You are so full of shit...
For years you went around telling everyone that you were the official Whipple dealer in the state of New Mexico.
Why not just tell the truth about your little vendetta as far as Dustin and Whipplechargers are concerned.
It appears as if Dustin has chosen to take the high road,when he has enough ammunition to make you look very stupid...(albeit not that hard to do)

[carreraboat]

Sorry playdeep as always you don,t have a clue.i never been a whipple dealer never claimed to be you might be refering to bob g. which is a whipple dist. I have no ill feelings toward dustin or whipple i think they are great products so i really dont know what you are talking about?if i thought they were such a pile why would i be building a new motor to install a quad rotor on for my own boat if i was a dealer why would i in another thread be asking where i could get the best deal on one?i think all performance parts have there own applications sometimes things just work better than others.

I have heard that the problems associated with either the procharger or the whipple chargers installed on the 496 has nothing to do with the chargers themselves. The new 496 engines have cast rods and cheap internals. I have spoken to a local shop who does a great deal of installations and they have said that they have problems with almost all of the 496's they install chargers on, yet zero on 500hp's with the same configuration and boost. They say that the 496 is a great motor in the stock configuration, but the h.p. limit is about maxed due to the poor parts they install in the engines. Don't know for a fact, but I trust those that I have heard it from.

I'll speak of mine since I have a Procharger on mine. 2 full summers and not a lick of problems. Would I do it again Hell Yes! I have'nt seen a Whipple on a 496 to ask them how it is going. As with any upgrades it's all about dialing it in correctly, period. I would say humoan error acounts for 90% of the problems.

[rivercrazy]

I wouldn't characterize the 496's as having lousy internals. The HO has a forged crank, forged connecting rods, roller cam, and inconnel exhaust valves. They do have the non forged hyper pistons.
To me the only real issue if you go blown with more than 3-4 pounds of boost are the pistons.

River, I agree. The guts in them aren't bad the weak point is the pistions. This is why I'm running on the 3# kit on mine. I pulled the heads this year just to look at everything and it was all good. I put in new Cometic head gaskets $$$$ but worth it when you are running boost. Slowing the aftermarket stuff is coming, J&E just made some sweet pistions for the 496. Still waiting for ARP to make head studs also waiting on connecting rods. Like I said 2 full summers and still good to go.

I have the first Whippled 496 and I also think I have put the most hours on one to date. I have 136 hours and am very happy.
I did replace the rockers & push rods to Crane rollers, but it was because of a Mercury stamped rocker problem, not a Whipple problem. The guys at Whipple spent alot of time putting this thing together before bringing it to market.
I am in the process of building a Whippled 565 for the same boat and have the 496 up for sale right now. At 620 HP, it made an incredable difference to my boat. Again, I am very happy.
If anyone wants to see one run, meet me in Havasu some weekend.

Gibbons:
I would love to see one run! hehehehehe

Have had a procharger on a 454 mag for 3 years. After ECU was programmed right have had zero problems. Biggest negative about unit is black soot on transom and changing oil frequently. Makes great power in mid-range and picked up 15 mph running 8 psi boost.

[SecondTake]

Gibbons: how much do you want for the whippled 496? Is it the HO? How many hours are on it?

[SHAKEN Not Stirred]

It's an HO with 136 hours.
Im asking $ 12,500
I have it advertised here on Hot Boat, with a photo.
It looks like I have it sold, but I'll let you know what happens!!!!
