PUT YOUR STOCK HIGH PRESSURE OIL PUMP INTO OVERDRIVE WITH OUR NEW OVERDRIVE GEAR ASSEMBLY FOR USE WITH ANY 7.3L HPOP. STICK IT IN FRONT OF YOUR STOCK EARLY MODEL, LATE MODEL OR ADRENALINE FOR SOME SERIOUS VOLUME!

You can run it with early or late model stock OEM pumps or your new Adrenaline. This unit is specially geared to allow for use with the Adrenaline even with stock low pressure oil. Feel free to order, but anyone who orders right now will be required to supply photos, truck bios and testimonial (good or bad) on your experience with the Overdrive. So, if you order now - you will be called about your BETA requirements before your unit ships.

To bring you this product for $999 is more than an accomplishment. As you can see from the quality and as you can imagine with engineering and legal fees, we are pretty deep into this. But, all we've heard for years now is that you wanted High Pressure Oil for under $1000. Well, here it is, for as long as we can hold it there. Inexpensive superior quality full billet exterior and internals with the flexibility to customize or upgrade with your changing needs. How can you beat that?  The internals are intentionally completely rebuildable - just in case.  So you can keep racing all season long.

The Overdrive is NOT A PUMP, it is a gear assembly that mounts in front of your stock HPOP. It uses OEM gaskets for a no leak solution. Our standard Overdrive units are geared at 1.66:1 for high pressure oil volumes that can exceed even our own large bore pump (The PULSE) when installed with a early model 15* stock unit. But we have many choices of gearsets. So, your Overdrive is always upgradeable, customizable and rebuildable! Get the volumes of high pressure oil we've been needing in these trucks without messy setups. This new "outside of the box" creation forces a more complete fuel delivery for maximum horsepower results. This changes EVERYTHING.

As we said, the Overdrive is NOT a pump, it is an enclosed gear assembly to speed up the RPMs of your stock HPOP.  The OEM pumps are rated at about 8000 RPMs, your stock pump can easily spin at higher RPMs - and does so in the 6.0L, I530 and I466 trucks. They've already proven the theory and the stock pump design at higher RPMs in those applications.

This new pump solution is making some people's heads pop off. As of today, the Overdrive has officially generated the most interest of any product we have ever introduced. Alot of you still seem very confused, but once you get it - you'll realize the potential. This isn't a concept... it already works.

The Overdrive won't pull fittings out of pumps, nor will it sling pumps apart. It does not cause excessive wear because of a hyper-speed. Pumps will wear.  Any pump. Time, dirty oil, sloppy assembly and cavitation will cause wear to your pump. That's life. One huge problem with the stock pump has been power loss from "spinning" in the housing. On our pump builds (Pulse and Adrenaline) we have avoided issues by pinning the pumps during assembly. Since 2005 we've been pinning all of our pumps to keep them from spinning in the housing from too much torque.  So we've never encountered problems. We've not seen this issue to date, but it's worth mentioning as it is a possibility even though it hasn't occured for us. If your pump "spins", you can send it in for a "pinning" - or you can send it in when you purchase the Overdrive to prevent this inherent problem from ruining your fun. 

Some basic info: Your stock pump is currently geared at 85% of the engine RPM. At 3000 engine RPM, the pump shaft is spinning at 2550 RPM. We gear our standard Overdrive unit well under a 2:1 ratio. 66.66% to be exact. That is the ratio of the new pump speed vs. the old pump speed.  The ratio pertains to the original drive gear of the pump - not to the engine. So, at 3000 engine RPM, your stock pump shaft speed was 2550 RPM.  It will now be 1.67 x the 2550. So, it will now be spinning at 4259 RPMs when your engine is at 3000 RPMs. We're actually still running some testing to decide if the 25% model would be the best choice for the standard units for daily drivers when we release them for that. We'll know that very soon.

Here it is in a nutshell: YOU HAVE NO HPOP LIMITS ANYMORE. YOU CAN NOW HAVE AS MUCH OR AS LITTLE OIL AS YOU DESIRE - as long as you can feed it with low pressure oil. While it is incredible what the Overdrive now brings to the market, what everyone seems to be missing here is this: We can make small stroke pumps with small pistons, small stroke pumps with large pistons, large stroke pumps with small pistons, large stroke pumps with large pistons. Small, medium or large of everything. Then we can put any of those behind several choices of gearing. That is pretty incredible and we're very proud of it.

Note to forum engineers (just kidding): All of the theories, issues, or concerns lurking out there about dual systems or some other pump systems do not apply. I get bombarded with questions like how will the IPR handle it? How hot will the oil temps go, etc? We've never seen any of these strange issues on any of our pump solutions So, install the Overdrive, get ahold of your tuner to adjust the IPR tables and enjoy your new ride.

The Maximum Overdrive is for an entirely different class of vehicle and it does have it's place. To finally put these numbers out there 3:1, 4:1 and 5:1 is some pretty potent "effect". And it did the job. We certainly got your attention. Some people are taking this way too seriously. Relax...Those numbers are just fun to look at. :-)

PowerHungry      "I have to make significant changes to how ICP is handled because I'm getting way too much oil for the stock tables to handle properly and kept having ICP overshoot to 3600+ PSI. Once the tables were retuned, this setup has all the manners of Clark Kent during normal driving but when you crack the throttle... Hold on! Superman grabs you by the collar and takes you for a ride! :D

There's no reason that this setup couldn't handle even the most oil-thirsty of injectors. I'd think it would still be smart to put the additional reservoir spacer in to bump the volume up and a higher volume LPOP wouldn't be a bad idea either. This truck appears to be pretty tight and so far I haven't had any issues with the reservoir running dry, even on a 30 second full throttle run to well over 100 MPH. Not so much as the slightest hiccup and pulled hard until I let out. ;)"

Mattr66 (400cc/400%)  "Well, I have installed an Overdrive and 100,000 mile, 17 degree HPOP in Betty (my black truck) and so far I am liking it.  I have the 1.67 model and I previously had another big oil system that worked fine but was more than I needed, I am in no way talking bad about it because it has served me very well.

Anyway, so far everything works very well.  The idle seems to be a bit smoother and startups are more instant.  On my street tune I have seen a measley 38% duty cycle and nothing suprising at full tilt.  I am also running the Dieselsite Reservior Spacer for extra reserve capacity and giving me more vertical column to separate any air that might get into the HPOP reservior.  I have also run it up to about 3600 RPMs so far (where my shift points are) with no hickups. "

ITPDiesel    "After installing my OD and driving the truck about 15 miles to get it warmed up and a bunch of the air purged, I made exactly 2 heavy throttle runs. I rolled into the throttle (didn't stab it) and may not have even made it to WOT before I backed out. Both times, running the same race tune and pump that would only make 2700psi on their own, I watched my ICP gauge and ScanGauge both hit 4000psi and promptly backed out of the throttle. I never datalogged this because I parked the truck and called Jody and told him I needed the tuning adjusted before I'd drive it again. I think he was a bit surprised by how high the pressure went. He updated the file, sent it back to me and the next test run the truck hit 3300psi and flatlined (except for where the ICP got pulled while the street tires were busy smoking miles off their life).

I need to get my datalogging stuff installed soon so I can get some good logs at the track with traction and 13 solid seconds of acceleration... "
