tazman7474: and look at how much is wasted... the flames from exhaust on overrun show that it is not all used :o(

Stevie: i have to run a carburater on mine, i had 3 of them custom done to maximize the mixture.(it has to do with the way the fuel is coming out of the boosters into the venturi, that cut the wasted fuel down a little. now we get more power out of it!)

Onderwerp: Re:
tazman7474: mine is mostly a road car, so that would be quite an expense for just those few times that it tracks

Stevie: actualy, what i had done should increase fuel milage on the street by about 15%!

tazman7474: My engine is probably too complicated for that sort of alteration, and getting the ECU remapped is not cheap :o(

Stevie: all it does is improve the fuel atomization, which brings it closer to what a fuel injection system would do. with yours being an efi motor, you're better off working on an intercooler and maybe an improved induction system(you've probably done some of that anyways)

Onderwerp: Re:
tazman7474: yep, Ive altered the air intake, I prefer it slightly rich anyways cos these motors are prone to blowing up with the slight sign of running weak,, as I found out last year. I can parralel up the fuel rails, as they are in series at the moment ( so means the final injector can be slightly starved,, and that just happens to be the usual cylinder that runs lean and fails.
I may look at a larger turbo later this year, and will upgrade the fuel pump again, and do the rails.. and then will fit larger intercooler or go for a front mount.. then I will get it remapped

Stevie: multi-port fuel pressure drops as rpms ncrease, so I could see where you could run into a problem there. its strange the engine manufacturer didnt use a larger injector at the end of the rail to compensate.

Stevie: With a greddy e-manage unit or a camcom, you can remap your fuel settings on the fly with your laptop.

Backoff: The system I go for will allow that also, and done on the road gets better results than on a rolling road also
