600sci - Whipple Stage X
 

My 600sci is down at the Whipple compound...just finishing up on the final stage of the upgrades for the 600sci, 662sci, and 700sci motors. We are calling this Stage X

Motor upgrades:
4.0 Whipple Supercharger
Whipple MOAC innercooler
KE plate oil cooler
Stock heads ported by Chapman Racing
Jessel shaft rockers
Morel Lifters
Custom Whipple Cam
Crank triggered ignition with individual coils
Callies 1/4 inch stroker crank (540 cu/in)
Oliver rods
Custom JE pistons (8.2 compression)
Dual stage water pump.
Whipple PCM re-program

We are hoping to make between 1000 and 1050 horsepower with under 10 lbs of boost so as to run on 91 octane 10% ethanol fuel.
At this point, the limiting factors will be the heads and stock GM, Gen 6 block.

Ahhh well... that will be for another day... A good set of heads and a Dart block at around 565 cu/inches.

I will keep you updated.

Here we go again!!! Looks like another project for the winter. Is 110 the new goal ??? How have things been on the other side of the state??? I hope that work has been good for you. I think that every house in seattle need a new custom deck!!! keep in touch.

Nope... 110 is not the new goal. My boat does a consistant 97-99 mph, with 100.2 being the best to date. Handeling is awsome. I am looking for the boat to do over 100mph consistantly, and Dustin wanted to do a 540 kit as the final stage of development in his 600, 662, 700 motor packages. He figures that when the time comes for most of these motor owners to freshen up their motors... lots of them will opt for a 1/4 inch stroker crank for more power. He wanted to be ready for that eventuallity, and I am the test mule.

Im guessing that the 540 will give me a consistant 4-5 mph over the 502 motor.

Work is going good. My company dropped about 40% in buisness between 2008 and 2009. We have come up about 20% for 2010. I think the other 20%, to get us back where we were before... is going to be a few years in the coming.

I hope you are busy as well.

Final dyno results are in on Whipple 600sci Stage X motor:

1067 hp @ 6200 rpm
972 ft/lbs of torque at 3750 rpm
torque at 6200 rpm is 903 ft/lbs

Wowser!!!

I think I am going to have to re-prop. :eek:

Chris

Wow, great numbers! Can the drive stand that for any amount of time? Seems like that would crush anything other than a 6.

Chris, Great job! Those are some killer numbers!

I'm also impressed with your ignition upgrade. Is your crank triggered CNP ignition running 496 coils without a distributor? Also, what size KE plate cooler do you plan to run?

Jon

I dunno... But ... I built a 598 for a customer with a 5.0 liter on it that produces 1301 hp and 1267 ft/lbs of torque in a 28 Magic cat... it goes about 132mph, and the SCX/SC lower combo that has been holding up.

Slip on that boat is about 10%, and due to me using Merc lab props with such a high x-dimension on my boat... my slip is typically about 14%-19%. The SCX also has a built in drive oil cooler.

Chris

Ignition is now a Mefi 4, and the coils are the stock coil packs off my 600sci. I believe they are the same coil packs that Merc has on all their crank triggered ignitions. ie 496, 525, 600 ... etc.

The KE oil cooler is a 13 plate.

Chris

That sounds good. I hope that Whipple goes to distributerless on all of its Merc Racing supercharger packages. I hate the idea of going backwards to a distributer just to add a supercharger--the Merc setup looks better.

Getting closer...

Looks good Chris. I like it better without the closed cooling.
Good luck with the testing!
Best Regards,
Steve

Nice!!! where does the hose go that you cant see in the pic go ??? Any bigggggg #'s yet??? I hope it purrrrrrrr's like a kitten.

The large (1") line is the output water from the innercooler... which I routed to the right rear of the boat...so I can see it flowing while driving.

I have not pushed the boat past 5000 rpm yet (86 mph) because it handles very strangely with all the weight removed from the rear of the boat (seat, hatch) and all my extra stuff in the nose.

Also... the motor is running too cold (72 deg) which is not allowing the computer to switch out from cold start mode.

I will be working on it tommorow.

Chris

Cool, let us know what the outcome is.

Comment:

Surprised they recommended the 13 plate cooler. Way! to much cooler! You need the 8 plate cooler and that might be too much.

The oil needs to get hot to burn off the moisture and fuel dillution. Currently having the same problem but I still run a tube style cooler but run a two stage pump which has more flow and keeps my oil kinda cool 155 degrees. Ideal temp for me would be 180degrees at WOT for several miles.

This upgrade might not be the best bang for the buck as you might as well start from scratch i.e... sell the HP600 and put in a nice BBC wet sump or dry sump with a 8.3 and call it a day.

Single engine V-Bottom hitting 110MPH plus is gonna be different keeping that boat balanced on the pad is not for the faint of heart. I know I have been there at 116MPH and again at 122MPH in V-Bottom.

Let us know what happens Chris you definitely have the sickness...laughing.

Talk to you soon.

KAP...

My oil temps are right at 190... which interestingly enough is right where the oil thermostat is set :grinser010:

Did some changes in water routing, and got water temp up to 85 deg. Dustin and Eddie say 100-105 deg is the magic number to make everything happy.

Guess I am gonna try a thermostat and bypass hose with three 3/16 holes in the side of the thermostat next. Water pressure is 15-17 lbs at 80... which is as fast as I took it today.

The engine has yet to get the water warm enough to let it idle down... which makes docking a bugger.

Hope you are doing well,

Chris

P.S. Have you gotten your IMCO shortie yet?

Chris:

I will try and call you tomorrow.
