Return to the Scottish Scoobies forum does anybody else get this??
  4. i do like the look of the engine bay though []
  5. tidy car but a wee bit too much "pimp my ride" look for me
  6. Sorry to hear that Russell..
  7. gonna be offshore []
  8. glad to see yer back mobile again []
  9. howz about just limiting them to a decent size??
  10. some pics in signatures are pretty cool
  11. OMG signatures are working again..[]
  12. lol another day in happyville..[] anyway which type of FMIC are they?? im gonna be looking for one soon (ISH) but maybe if the price is right ill take one now.. can ya PM me with some details.. Cheers!
  13. fireworks display at end was pretty cool too []
  14. for anybody that may be intrested (or understand more then me lol) For Info Henko Racing/Walbro Fuel Pump and general fuel system information Weare commonly asked "what is the difference between the Henko Racing/Walbro pumps? I thought they only had a 190lph and a 255lph pump...?" Well, there are actually quite a few different pumps that they offer. First, we have the 190lph, the 190lph-HP, the 255lph, and the 255lph-HP. Then we have the "flipped" versions of the 190lph, the 255lph, and the 255lph-HP (no 190lph-HP). SEE PIC BELOW. These pumps have the inlet rotated 180 degrees from the inlet. The reason is to allow for a greater number of fitments. With these 7 pumps, Henko Racing/Walbro can fit numerous vehicle applications. Other than that, each "series" of pumps is the same in terms of fuel flow characteristics. Fuel Pump Matrix 190lph 190lph-HP 255lph 255lph-HP GSS250 F20000141 GSS317 GSS342 GSS278 (flipped) N/A GSS315 (flipped) GSS341 (flipped) Anotherquestion we are asked is "what pump do I need and what is that HP about?" That questions is simple but technical at the same time.....to be continued Regardingthe HP question, that is fairly simple. If we take the two 255lph pumps and look at the pressure curves we see that they are very similar until about 60psi. After that point, the standard 255 pump starts to die off whereas the HP keeps going. Touse an example to illustrate pump choice, we will look at a turbocharged Acura application. On these vehicles, the OEM fuel pressure regulator is referred to as a 1:1 regulator. What this means is that for every pound of manifold pressure (boost) there will be a corresponding 1 pound increase in fuel pressure. If the base fuel pressure is set at 40lbs and we introduce 10lbs. of boost, the total fuel system pressure at boost will be 50lbs. That sounds good and will work fine with a standard 255 pump but there is one small problem. Theproblem is that we still need more fuel than the 1:1 regulator can effectively deliver. One way would be to add a larger set of fuel injectors and use an aftermarket engine management system to control them. The other, more commonly used method of fuel enrichment is the rising rate fuel pressure regulator or FMU. This device functions in a 4:1 (or more) ratio and will increase the fuel pressure 4 pounds for every 1 pound of boost. If we once again set our base fuel pressure at 40 lbs. and add 10 lbs. of boost we will now see 40 additional pounds of pressure for a total of 80lbs. of fuel rail pressure. This goes beyond the capabilities of the standard 255 pump and mandates the use of the 255HP pump. From this we can see that given two different engines, both with a hypothetical 400hp, the one with the larger pressure requirements will need the HP pump, the one with the smaller requirements will not.
  15. hopefully ill be home for this wouldent mind going back again this year
  16. way to go shazz. [].do i see a new scoob (turbo) looming on the horizon??
  17. tidy looking i gotta say that much
  18. ok cheers squirrel m8..was just needing some info on em before i paid for it but too late now lol..comes with a 12 month guarentee though so hopefully its a decent enough bit of equiptment
  19. at least ya wont have to eat the food..i assume [:#] good luck anyway []
  20. anyone??
  21. lol thats a cracker..i didnt know gumball did that for a living!! []
