Before I start I want to go through the a check list;

Supernatural 3.4L 250WHP. CHECK

Supernatural 3.4L 300WHP. CHECK

Supernatural 3.7L 350WHP. RUNNING

Supernatural 3.7 9,000RPM. DEVELOPMENT STAGES/LOOK BELOW

Let start shall we!



2.8L piston weight


3.7L 9,000RPM piston weight


2.8L piston pin weight


3.7L 9,000RPM piston pin weight


Supernatural 3.4L piston/rod combo weight


3.7L 9,000RPM piston/rod combo weight


2.8L VS 3.7L 9,000RPM piston comparison


3.7L 9,000RPM rod VS Current Supernatural 3.7L rod
Even though the displacement is equally the same the difference in rod size makes for a completelly different application.
So that means a completelly different cam and intake combo are required.
I'd like to see a vendor offering different cams for two different geometries with the same displacement! They don't have the R&D on the matter.

Enjoy the journey!

Nah, 1/4" of AR500 steel should be fine.

I might need the thickest plate behind the brake pedal!!

Heads are at the machine shop and the intake drawings at the fabricator.

Have you thought about getting/renting a setup to test engines by themselves out of the car?

Might give more consistent results, removing the variables from the car, and also you don't have to be right next to the engine if it blows up.

Kind of. I'm looking to build an engine break-in chassis for the 60*V6. I don't have patrons or sponsors so if someone wants a specific test to verivy BHP I'll be more than happy to do that for them if they can pay for it plus my R&D time.

When I was going to school for engineering one of my class mates made an engine stand from some square tubing he had laying around. and brought it in for one of our teachers who needed one for a project car. they don't seem that complicated to make if you have decent welding skills as t hey are very basic. the real cost comes from the gauges and the battery needed to make it all work.
