please explain how a crank machined from a forged "billet" is stronger than a forged one. this is contrary to my understanding, that the directional grain flow makes a forged part stronger.

Mostly it is due to the difference in material used, not the process itself. Most I believe are a 4330M not the normal 4340, and they do use a Timken steel on all of them I believe.

The other would be how it can be made. Since a raw forging does have some limitations, you can make the billet piece into anything you want to add or remove material were needed to make is stronger, lighter, heavier...what ever the case may be.

That fuel pump looks serious! (along with everything else for that matter)

i keep staring at the two pictures but i have no idea how that pump works.

0HP RESEARCH

These are typically belt driven or direct drive off of the cam. Without the brackets it is hard to see.

Here you can see a similar pump used on a vintage funny car.

So much eye candy and bad assery in this build! Can't wait to see the results!

What’s the lever on the pump do?

0HP RESEARCH

Shut off valve. Since it flows that much, in case something happens you need to be able to turn the fire hydrant off.

Makes sense. That thing has to be moving a lot of fuel

Given the fact it is using 700 lb/hr injectors....yeah a little bit. Most 1300-1500 rwhp cars typically use a 180 - 200 lb/hr injector

Any of the Ti valves are going to be coated no matter what so that helps a lot. Generally there is going to be either a bronze liner or a Beryllium-Copper liner, which is what we used in this one on both the intake and exhaust. Mainly we went that way to help dissipate heat.

Nice thanks for the response

Why not run the Jesel bushings on the lifters? We run the same set up in my car, it was advised by jesel to run the Amco-45 bushing from them, so that has a .060 hole drilled in the bushing helps keep the lifter's pressurized oil feed in range to receive oil. As I am sure you are running a pretty big lobe on the cam. Great looking build its identical to mine, minus the rods.

did op ever say what the compression would be?

0HP RESEARCH

No....a few details of the build I am not at liberty to disclose.
