RJ MFG New Oil Pump Gears (Rev to 9k!!!)
Hey Guys, I have been off and on the phone today with the guys over at RJ MFG! They have some good news! Finally, an upgrade to the factory oil pump to allow us to run higher RPMs! Below is the simulated oil pump upgrade.
I just confirmed that their oil pump gears passed the bench testing by within 3% of the simulation model all the way to 10k RPMs and held 90 psi of oil pressure for 5 hours while being put through a torture test to simulate the strains of shifting and over-revving! Safe to say your oil pump will no longer be the weak point in making Hi RPM runs! RJ MFG is now a vendor on here and have told me that they will be offering a introductory special of $699 shipped for the first 10 buyers! the retail on these will be $749 MSRP... Once I have the bench test results I will post them up. Note: Factory gear is sintered metal construction with a tensile strength of ~6,000psi RJ MFG gear is harder Chromoly steel with a tensile strength of ~140,000. The issue with the powder metal units is micro-welding to the crank. The new design should effectively eliminate that issue and a 10k 5 hour torture test would have seized a factor gear within seconds! So who is interested? First 10! 1. Bullitt5897 2. Zeliminator 3. Juicinjake 4. Juicinjake - 2 5. 6. 7. 8. 9. 10.

I talked to RJM at length at ZDayZ about this. I'm interested but don't have the cash now right. Just got done remodeling the kitchen. With what I spent on that. I could have out done bullitt.

I wouldn't account you running these gears as a good tester ( no disrespect) but you have enough money in that motor to buy 20 370z's. I think alot of people will buy these gears and blow up alot of motors thinking this is the solution to rev to the moon ( reason behind that is they will not get the additional support mods for the application, we all know there will be a handful that will do this). Sasha already proved that the oem crank can with stand 9k but not for sustain period as micro tears will form 9 but he did run a dry sump). So my question, are there any road racers or race teams going to hop in this group buy, to test these gears in real world situations. I hope these gears do hold up to the abuse of raising the redline.

I am building a 3.7L block... But again I like you said will be investing in the parts to make a true 9k machine. That means sunny Bryant billet crankshaft to go with the billet gears. I am going fully forged internals (rods,pistons) and I have a built set of heads which if all goes as planned will have the new jwt cams. Like I mentioned earlier this just eliminates the first major hurdle which was the oil pump. The world challenge guys did this prior to 2012 in their racecars because dry sump wasn't homologous for the series. As far as race teams picking this up most will go dry sump but for privateers and the rest of us this is a tried and true solution for a 9k oil pump.

So you're building 2 cars now? Well looks like you're going to beat me to my idea. I'm going the same route minus the bottom end build. Are you going with the stage 1 jwt cams?

Doubt it, The stock internals can only withstand so much abuse. I.E. stock crank.. Might have to swap out for a better one...
Can someone confirm this??

Also, only building 1 car... selling my 4.5L short block too much torque for a High HP Build... We are already @ 800ft/lbs by 4000rpm if we kept going the car could have made north of 1100+ft/lbs at the same rpm level now imagine trying to get that to hook!
