848 Conversion to 5 Liter Whipple

So today one of my best customers showed up after a long drive from Luisiana to have his 848 turned into a 5.0 liter Whipple motor. It is a 6-8 hr conversion including the reprogramming and clean up. The motor we start with is a 540 ci 8.75:1 engine with a VERY stout bottom end. With the compression being so high, the boost needs to be held to 7-8 lbs on pump gas, but can be taken up into the teens on race fuel for a VERY sunbstantial HP gain. . This RPM 26 Cat ran an easy 118 mph in the Spring in LA, and we will be doing some testing out in Havasu on Monday to see how it does in the AZ heat. Here are some before and after pics

Gary,

Thanks again for all that you have done, my wife and I had a wonderful time with your family and are looking forward to you and your wife coming down to our neck of the woods for a party. Cant wait for tomorrow on Havasu I really think that the boat/motor combo is going to blow everyones minds, including mine. Anyone needing a motor, look no further, call Gary and forget the rest, you will get the best bang for the buck and by far the best customer service bar-none...See ya tomorrow Gary, we will swing by and scoop your wife up on the way out, she won't have much choice then

Put up some pics of the whole boat. The motor looks sick i would be excited also.

Not so much of a jump in power, but the engine is so laid back now it jumps to any speed with no effort at all 70mph 0 boost, the motor is so smooth you know other boats are watching you thinking he got the boat, but why didn't he get the motor, then you blow his azz off the water but he turns and runs

Congrats sounds like a fun day.
