installed on 2000 7.3 with 230/80 rosewoods, seems to be a good match so far, more pressure at lower rpms= more power

Great pump! Great service!

I will say to make sure which ever year pump you need for your truck you need to send in that year core but otherwise great pump and service !

I have 250cc/200% full force injectors and this pump has been supplying them fine for about 3 years now. Would definitely recommend.

Truck runs smoother and idles quieter than stock. My 185 cc single shots don’t require aftermarket hpop but even so it makes a huge difference.

Works as expected, seems to be well done, ordering process is a little complicated, wish there was someway to communicate with the repair shop. I would use them again

I bought this pump a few months ago which for new buyers it is your existing pump that is upgraded and sent back to you. I would give five stars for this review except when I got the pump back and opened it the bag was full of oil the bag leaked all over the box and it was a mess, lucky the box stayed intact, they did a helluva job packaging it for sure. The pump was fairly clean and nice and lubed up, however when I went to install it and removed the port plugs there was a lot of hardened Loctite looking material in the flow ports a very hardened greencompund looking identical to the loctite used to seal injector cups. If I could share photos I would. From my concern I installed the pump on a bench stand and drove it via ac servo motor. Using a pot I trimmed the IPR to act just as it would or relatively close to what the ICP would call for. The pump operated well, no hiccups and constant pressures up to 1k psi, I did not want to drive it 100% in a test condition. I felt good about it after finding a contaminate such as I did and then testing it. The pump took nearly 3 weeks to get back, f.y.i. I wasnt in a hurry as this repair was an entire truck rebuild. The pump is in driving single shot 180/30's from rosewood with a good set of tunes from JELICH, on a hydra, the pump performs no doubt, I've had dominator pumps and a no namer pumps from no name names that is out of business now and this pump TERMINATOR 500 is quality thus far and seems to be the best bang for your buck at nearly half the cost of allmost everything else its proven to be a decent pump.
I went with it to see what it was about, I sent a newer bosch that was a decent working pump into them for a reman and this is definately rebuilt speaking out if there are any naysayers reading this, I have living proof that Terminator engineering is legit.
Once again the boys at riff raff are indeed dealing with reputable folks providing performance upgrades.
The pump has produced 6k in psi under wot with a 15k 5th wheel tied on. As Impressive as the competitors are this is a competitive pump the flow rate is decent, above avg, so truely the best bang for your performance buck. As old as the 7.3's are becoming a place still offering a modded performance part like this at the current cost is a rarity by itself. Way to go riff raff and terminator.

A very satisfied customer

Works great pushes the 250cc injectors just fine.

I sent my working core in for an upgrade to the T500 received it back and installed the unit, No Start, leaking from Non Serviceable port, sent it back said it was fine, received it back, installed it, No leak, No Start. Pump will not build pressure, beyond 179 Psi, checked everything, all new OEM parts, spent thousands chasing ghosts because they said pump was fine. dead headed pump, shows 345 PSI, wasted thousands of dollars because of sloppy workmanship, should have just gone with a standard part instead of junk in a box.

Highly recommends this pump if you need to preplace your hpop or you just want to upgrade.
