No Bullshit Fuel Filter
You gotta love a company like Injector Injector Dynamics who puts the following on their home page and then walks-the-walk by offering innovative products backed by data:
As a results based engineering company, we have a STRICT no BS policy. Our product information is backed by data, and sound engineering principles. Our strict adherence to facts has earned the respect of many, but our willingness to call BS when we see it has created a great deal of controversy. We accept this controversy as a small price to pay for holding the industry to a higher standard, and we will continue to push for a motorsport community that makes decisions based on facts, not buzzwords, nonsense, or outright falsehoods.
I saw this video made by the company's founder showing a prototype and it took them a year longer than expected to productize it. Apparently they didn't want to release it until they had it right which is fine by me.
It came very well packed in a large box packed with the starch-based peanuts so they score well with environmentalists as well as my kids who love to dissolve them in the sink. I'll only outline what's in the video and this spec sheet:
Only filter I've see with actual testing data
Meets Bosch's specification for the protection of fuel injectors
Holds a high-level of contaminants while maintaining low restriction to flow
Delta pressure gauge indicates how clogged the the element is
Schrader valve to relieve pressure and drain gas
Spin on/off canister with no-tool safety latch
Optional pressure and temp block and sensor
Integrated mounting bracket
Some details:
Inlet/Outlet: -8 SAE J1296 P;
Pump inlet should be -8 or -10
They made made 1450HP wheel on a GTR with stock bends on a -6
They like to drop two Whalboro 450s or 485s

Fuel Flow Calculations
Fuel flow is measured in gallons per hour (GPH) or liters per hour (LPH). To ensure that the engine has
A 747 burns about 1 gallon per second when cruising which is 3,600 gallons per hour.
While flow is important, what really matter is that fuel rails have consistent and stable pressure.
Optimal GPH = (Max. HP x BSFC) / 6
Brake-specific fuel consumption (BSFC) can be determined using an engine dyno and other equipment to determine how much fuel an engine consumes over a specific period of time. I didn't have that done so I'm going to use a rule-of-thumb number.
Estimated BSFC at wide-open throttle (WOT)
.5 naturally aspirated
.55 nitrous
.6 for turbo
.65 for supercharged
Optimal GPH = (1,000 * .65) / 6 = 108.3
The Holly 12-125 is rated at 125 GPH free flow and 110 GPH at 7 PSI

Post on sealant; Found out some things you may want to know. In talking to Permatex, they advised me that they had to rebuild their formulas for thread sealer and this new stuff is not as effective on todays gas as it used to be. As I understood it, the main ingredient that proved so effective on the ethanol in gas today, was South Georgia Pine Sap....the irony here is, its where I live. It took several months for gas to eat thru my Permatex thread sealer and start to leak.
Anyway, the recommended product from the technician I talked to, to use on tanks (I have some on order) is Gasoila E-seal Thread Sealant (Yellow Can). It is designed for E-10 and E-85 blended gasoline.
