fuel enrichment besides andial

gt_diesel · 09-05-2006, 07:43 AM

So, I have been looking over my car, and I do not have the Andial setup on it for fuel enrichment. When I talked to the guy I purchased the car from, he said that it does have an enrichment setup on the car. I called the engine builder, and he did confirm, that the car does in fact have 7th injector that will fire when the car begins to lean out, but he did not recall what system it was. What other systems are out there, and how do they work / tap in to the fuel system... I really want to see what I have for an enrichment setup on the car before I take it to a track day. So any info would be great, pictures of setups would help me greatly.

Thanks

I don't know of any other, but to be safe you ought to put the car on a dyno and check the air fuel ratio at different loads.

911 Sc Cold start valve, Hobbs or simular adjustable pressure switch set to fire on boost mine is set at 10lbs. Easy works well and is cheap.
I have my 7th injector spray just before the throttle body for good atomization.

I just took the car out messing around, and you can definately feel it work... I get it up around .6 bar and just give enough throttle to maintain that level... Then just a little above that, wham.... it will take off with no additional throttle.... I take it that is what it going on anyway.

Going richer than 12 to 1 is a waste of fuel and horsepower.
Yes it does protect against pinging, but retarding the timing will do the same thing without giving up as much power and without wasting fuel.

If you are richer than 12.5 to 1 under full boost and that isn't enough to keep the engine alive, think about going to an ignition retarding system, backing off the boost, or running a higher octane.

The car has a Electromotive Crankfire Ignition that has been all tuned and programmed... Just one more thing to keep the car safe.... I am sure it is fine, the engine has around 10k miles on it now with no problems. knock on wood of course!!!

The safest thing you can do for your engine is ditch the 1.1bar spring. At 8.3:1 C/R you are potentially nearing the danger zone. (I say potentially because there are so many variables).
