Pump Chart!
(Chart attached)
Gear Size Differences:
There are actually 3 different thicknesses of gears. (Street) 91.5-00, (Street/Strip) 01-05 thickness, and a custom boundary thickness (Race) that's even bigger.
Labor Differences
Porting/Honing/Machining/Shimming
Every pump varies in the actual work we put into it. I don't have the conclusive list here, but the race pump gets the most, and the street is a blueprinted stock housing with our billet gears inside. The Street/Strip is in-between.
Torque Guard
I coined the race pump to have "torque guard" because it produces a lot of additional pressure in the low RPM range. So if you're running a turbo or super with lots of mid to low end torque this will really add some extra protection to the bearings.

i know how they work, except for the shimming part (just havent looked into it yet)... im just trying to understand the differnce between the "street" pump and the "street/track" one... if i can get away with spending 250 vs 450 for no sacrifice. im all for it...
butttt since i see that the street one isnt shimable, im assuming i need the street/track one....?

If you're not running an 01-05 VVT Engine I would get the street pump. I need to figure out a new naming convention for these... I think that is what is confusing people...

^I don't want to confuse this even more, but I think Travis was trying to say Street/strip for 01-05 and street for the non-vvt and earlier.
At least that's what he has said before and that's whats in the "chart" above.
Look at it this way:
Street- OEM pressure, but higher durability
street/strip- Higher PSI
Race - Even higher PSI and Torque Guard (higher low RPM PSI).

Street now = "Basic Flow" for high HP cars with standard oiling requirements
Strip now = "VVT Flow" for high HP cars with VVT or other high oiling requirements
Race now = "Superflow" for cars needing more oil pressure at lower RPMs and excessive oiling requirements.
BLAO!

I don't wanna whine, but I'm going to build a vvt motor and don't want to spend $420 on a pump... Any chance you could sell a 'street' quality vvt sized pump?

So the VVT guys have little options right now for a lower priced unit ? Where do you see the limits of the stock VVT pump in RPM and rough HP/TQ ratings. $420 is a huge percentage of the cost of setting up a built motor, and I have not convinced myself to go that way yet.
