- ALL SPA Turbo components are GUARANTEED ethanol.
- (E 85& E 100) AND methanol compatible.
- Who else can guarantee this? NOBODY!
- SPA Turbo Composite 14:1 FMU
- Up to 14:1 adjustable gain rate
- FMU = fuel management unit
- SPA composite Fuel Management Unit
- Lightweight and virtually in-destructible.
- Ethanol and Methanol compatible and SAFE
- Easy installation
- FMU has a adjustable, boost referenced 1:14 raising rate
- Fine tune the fuel pressure that your motor will need while under turbo - boost.
- 8mm inlet and 8mm outlet fuel ports
- 1/4" boost reference port
- Adjustable from 10 psi to 100 psi fuel pressure
- All SPA Turbo FMUs can also be used as fuel pressure regulators.
- In other words, if you need a fuel pressure regulator, and are thinking of later upgrading to a turbo system, save money and get The FMU instead of just the FPR.
- We've had a few questions about how these work, so here's clarification:‚
- Initial line pressure is adjustable from 10 psi to 100 psi - boost referenced fuel pressure increase is also adjustable.
- The boost referenced pressure increase is adjustable from 1:1 to 14:1 meaning that the fuel pressure will increase proportionally with an increase in boost.
- Here's 2 examples:
- If you are running 10 lbs of boost and 1:1 ratio, your fuel pressure will increase by 10 psi.
- If you increase the boost referenced ratio to 14:1, your fuel pressure will increase by 140 psi.
- If your initial fuel pressure is adjusted to 100 psi, your total pressure in the first example would be 110 psi and 240 psi in the second example. However, 240 psi would require a heavy duty fuel pump.‚
Fuel pressure regulator bracket
- Allows perfect fixation of the fuel pressure regulator in the desired location.
- Fits all SPA Turbo fuel pressure regulator.
- Can also be used on other fuel pressure regulator with fixing holes as described in the "Technical Drawings" tab.
- Made of high quality galvanized steel.

Amazing socks but false advertising. They changed them.
Size: Large, Color: Black (6-pairs)
Okay well I have 4 stars because these are the best socks ever, infact, I threw out all my other socks and switched to just these. No show and they never slip. THE PROBLEM NOW, all the pairs I ordered before had a white symbol, and every time I buy more they have the grey and they are not as low show as my others… I wanted to simplify life and have all the same kind, no matching of colors or slightly different shape, but 4 times now I’ve ordered white symbol and gotten thicker longer ones with gray symbols. I’m considering switching all of my socks to the gray…. But the white symbol ones are way better, they don’t show with hey dudes on and gray symbol ones do now. I’m at a loss. Can someone tell me where to buy 100 pairs of white symbol so I never need to buy another sock again in my life?
