3.0, part one

Can you say "Three point -OH"??

"This ain't no six cylinder either!"

Primarily built to debut the new cylinder heads we are working with, this engine will see many different versions, many dyno hours, then it will be installed into one of my personal vehicles and used as a daily driver!

The primary goals for this engine and testing are:

  • To provide a solid base engine for testing of our MassIVe cylinder heads with comparative data derived from back to back dyno tests between a stock "super modified" cylinder head and our modern version with a Type I style exhaust port. This will give us direct comparison from HP to cooling.

 

INTAKE FLOW @28" TEST PRESSURE- THIS IS TRULY MASSIVE FLOW! EXHAUST FLOW @28" TEST PRESSURE, SIMPLY AMAZING.
  • To prove the strength and rigidity of the stock Type IV engine case. The case we have chosen is an early, low mileage 1.7 liter case.

  • To prove that our MassIVe DTM cooling system can effectively cool an engine nearly doubling the stock type I, and do so well enough for the car to be street drivable for long distances for thousands of trouble free miles, all while making 250+ BHP!.

 

 THIS IS THE ESTIMATED POWER PLOTS FOR "MASSIVE 3.0 V1" FROM OUR PRO VERSION SOFTWARE. TRULY AMAZING POWER FROM A 10:1 STREET ENGINE. THIS PLOT IS WITHOUT OUR ROLLER LIFTERS, STRUTTED LIGHTWEIGHT PISTONS AND IS NORMALLY ASPIRATED
  • To act as a test bed for the development of an engine program for midget race teams in the future. This will be accomplished with a version of around 2700ccs by dropping in  a shorter stroke crankshaft, while retaining the same bore size. If this engine can make the power needed, the Type IV will take the circuit by storm!

  • To further develop our roller camshaft and lifter advancements.

  • Derive more data from large displacement for the "Kitcarlson EMS" and compare the system to an "Autronic EMS" system that is a lot more detailed to install and more expensive.

  • In the final version this engine will be outfitted with another special set of custom Nickies cylinders specially prepped for withstanding massive boost and it will be turbocharged using a custom arrangement from Marty at Staggs Racing. That should be amazing to say the very least. The system will fit under the deck of a 63 beetle, the vehicle that will most likely have the final project installed after the testing is over. WHO KNOWS WHAT IT WILL MAKE FOR POWER!

KEEP IN MIND, I'M A CRAZED FANATIC AND THIS IS NOT MY DREAM ENGINE. MY DREAM ENGINE IS "PROJECT X" AND HAS BEEN PUT ON HOLD WHILE WE GET SOME DATA FROM THIS CURRENT 3.0 ENGINE TO SEE IF SOME IDEAS WE ARE USING WILL WORK!! "PROJECT X" WILL EXCEED 3.5 LITERS AND WILL BE BASED ON A STOCK TYPE IV CASE !!!!

 

1.7 ENGINE CASE FROM 1972, MORE THAN CAPABLE OF HOLDING THE MONSTEROUS INTERNALS OF THE 3.0,EVEN THOUGH ITS 32 YEARS OLD! A HUGE CASE REGISTER, AND A "LITTLE" CLEARANCING OF THE ROOF OF THE CASE! A BETTER SHOT OF THE CASE CLEARANCING. MOST LARGE TIV ENGINES HARDLY NEED ANY CLEARANCE WORK TO FIT A 78 STROKE CRANK, THE 3.0 HAS AN 86MM STROKE.

Here is a tad bit more clearance work. The pic on the left is an odd one, as it is normally never an area of interference.

 

Lifter bores after being honed for ceramic lifters, and one set of comparative heads for testing.

105.07mm "Nickies cylinders" and matching JE pistons. In "MassIVe 3.0 V2" these pistons will be traded out for set of strutted type Nascar forgings that weigh about 1/2 as much!

Coated bearings, Ceramic lifters, and straight cut timing gears

86mm Billet Crankshaft from Scat, after being cryogenically enhanced.
