Re: My RCR "DPE-962X" 8500 RPM -1850HP Engine Build *lots of pics*
Merry Christmas and Happy New Year Everybody !!!
Update:
Here are some more pics I would like to share with you.
I raised the bar on my DPE 962X project and will be going for 1850HP twin turbocharged HP.
I will talk to Fran in a couple weeks and see how we can re-enforce the chassis to make it a bit more rigid to handle the additional stress.
The first picture is a schematic of the Octane on demand fuel system I drew up and will be putting together. It will support over 2000 HP. The whole fuel system will all be plumbed in hard Stainless steel line. I just purchased a variety of benders and high quality flaring tools to do the job.
I sent my aluminum Intake manifold back to John Beck for him to install a second set of fuel rails since there will 16 injectors fueling this engine.
Here's a quick explanation on the fuel system logic:
The cars fuel cell will have 2 chambers. One 15 gal for 93 pump fuel and one 12 gal for 116 race fuel.
The primary 70# injectors will feed the engine 93 octane premium fuel until 15psi of boost. After that, the secondary injectors will add 116 octane race fuel to the 93 raising the octane rating and eliminating the chance of detonation up to about 32 psi of boost.
At lower engine RPM's there isn't much velocity to pull 100% of the fuel into the intake ports so the primary fuel rails are located close to the head port so the fuel sprays directly on the back of the hot intake valve. That eliminates puddling in the intake port for great fuel atomization and great responsive low speed driving.
The secondary fuel rails feeding the race gas are further up in the runners which is a good thing. That's because when the secondary injectors fire there will already be extreme air velocity in the intake ports to atomize and pull all the race fuel into the cylinders.
There will be 3 fuel pumps total keeping fuel return to a minimum and fuel cool.
The 2 Primary's pumps are Bosch 420's. The 3rd pumping the race fuel pump will be the SX 18207.
The 1st fuel pump will be activated when the ignition is turned on and will stay on as long as the car is running.
The 2nd fuel pump will be active at boost levels exceeding 10 psi.
The 3rd fuel pump feeding the 116 race fuel will be activated at boost levels exceeding 15psi.
I have decided on the Tec 3r from Electromotive engine controls for an Engine management system.
The trans-axle unit will be a Mendeola unit with a 13" pinion.
ARE Stage 3 Dry Sump will keep it lubed at extremes and also allow me to retain my factory A/C. A Jesel Belt Drive system will keep the valvetrane happy.
The Billet Valve covers will have built in oil sprayers to keep the valve springs cool at high RPM's and clear the Jesel valve trane.
