Whipple 5.0/W305 efi Engines

These motors are the "hot topic" right now, so I thought I would post some pics. They are truely what I would call the wave of the future. They make power effortlessly. In fact, you have to really "TRY" to make a 540 make less than 1000 HP on pump gas, with the right set up of course. At any rate, they are very nice and super reliable to drive around. They feel NOTHING like a quad rotor set up at all. The throttle linkage is super smooth and very manageable at any speed. Here are some pics. Also, Watch for something new from TPI coming in the near future with these

Need a little video of at least one of those bad boys running !!!

I'm working on it They are actually pretty boring to hear run, but man they sure feel good pushing the boat!

Thats the thing, I guess they look kind of "Beasty", but they do not drive like it. The throttle is So smooth that it transfers the power through the drive at a nice even transition. I personally believe that the way these motors deliver power, is a big factor in keeping an XR based drive around, without constant failures. Also, the fuel economy is unreal,,,,,,,,,,,,compared to an 800-900+ HP motor with a different induction system.

Dear Gary:

I couldn't agree with you more about the future of supercharged induction for marine applications. The Quad Rotor is dead and the future is this axial 305/(5) Five litre, from Whipple Inc.

As far as a compatible hull for these motors---Hmmm, I am somewhat biased but the NEW 36' Bullet would be the perfect showpiece for these motors.

Currently, the fastest 28 foot V-Bottom combination in existence is a TPI/28 Bullet. Hence, it seems only fitting for the first customer to purchase or own a 36 Bullet to continue the tradition and put some TPI powerplants into the hull. In my opinion, this combination would be tough to beat in terms of performance bang for the buck.

In anycase, no matter what hull a customer comes up with that base 540/305Whipple platform is hard to beat and very versatile.

Very truly yours,

KAP

P.S. I look forward to seeing you at Desert Storm as well as Demoman, New2cats and many others.

Thanks Kap,

But I would be surprised to see one of these in the first 36 Bullet. If I had one(a 36 Bullet), I would absolutely run two of these with #6 drives. That would be an incredible machine for sureThe motors are tunable on pump gas from 900-1100HP

Absolutely,

I would love to get together with all of you guys for a picture and a cold beverage on Saturday. After the speed run of course My kids will be dieing to swim and relax somewhere. Hopefully in a place where we can watch the "fast boats" run Adam, you are going to love the new interior in the Bullet! It looks sharp!

OK, Back to 5.0 Litre Whipples..........................

It's not often you get to see the Whipple 3.3L(200ax) at left next to the Whipple 5.0(305ax)at right. There is a substantial size difference

Damn, the 5.0 is huge.

Dear Gary:

Those photos tell a thousand words. What a great idea to put them side by side for comparison.

Uh! can we see the intercooler's for each side x side. I take it the 200AX uses a standard size and the 305 uses a MOAC.

Question(s):

1. Does the 305 fit under a standard hatch?

2. How much longer is the snout/pulley assembly on the 305 if your doing a conversion from a 200AX to a 305---In order for it to clear the back of the seat or engine compartment for clearance purposes? [I would guess about 3-4 inches]

3. Last can we get those in different colors? ie... let's say racing blue?

I'm simply saving my duckets for the future and these questions would be issues for both myself and someone whose thinking about these very same questions on a new build.

Very truly yours,

KAP
