car is going crazy Options

[d0w0rkS0n]

hey everyone, quick question.

I was in the process of boostin the car last week. had everything done. <255 Walboro, 460 injectors, feed lines, drain lines, turbo mounted and Intercooler piping ran> had the car towed up to the shop to have a downpipe made for it, but, they didnt have the right flange in stock and had to special order it. i couldnt go a whole week without my car. so, i got my car back. put the old exhaust manifold and car back on. Walboro 255 fuel pump and 460 injectors are still in.

now when i start my car... my car idles like crazy and im running very rich. i understand im rich cause the extra fuel going into the motor. but would that explain the insane idle too? it seems as if it is missing. but, i pulled out ONE spark plug at a time to see if they made a difference. all my spark plugs and wires are fine. so then i unclipped each injector one at a time. and those are all fine. car should be going back to the shop this week to finish the turbo.

but i would like to see if i can fix the problem. any thoughts? am i right about the fuel

your running too rich. rich = misfire if its bad enough.
what are you using to control fuel and send air pressure to your ecu?

You have answered yourself.

less fuel would be a good start, read the things manual.


but its going to be nearly undriveable until you have someone who knows what they're doing tune.

This is why you gather all your parts first for less down time if needed.

Just put everything back to stock until then.

I did gather all my parts.... The shop was supposed to have ordered the correct flange...

So your stock injectors flow, say, somewhere around 190cc/min and you put in injectors that are now flowing 460cc/min into your engine, and since you aren't taking any fuel out with the SAFC you really are forcing like two and a half times more fuel into the engine as it's designed to handle.... and you don't see how that would be the source of all the problems you're having?

seriously.
besides, the 460s are WAY too big for 99% of the 7a projects.
somthing in the 360-390cc range would be a much better choice, your gonna have to pull out a TON of fuel to get that car to idle well and drive properly.

i foresee more fail from him.

i know it was fuel... i said that in my original post i believe. i used my neo to cut out 20% of the fuel and its runnin fine now....

and thanks for the support Bitter....
