Air/fuel BAT fuel info

[A4 TSCHUSS]

Hey people, I just wanted to let people know some stuff that may have similar setups so they do know a reference point.

I have been running 16psi since my clutch slips but last night I turned the boost up to 21psi.

I was seeing 12.5 and 12.6:1 air/fuel on my wideband gauge running the 21psi so at 24psi im sure I would have seen like right at 13:1.

My car
2.0 (83mm bore)
AEB head
Schrick 252/260 cams
stock fuel lines
040 fuel pump
630cc injectors
GT3076
Methanol Injection

Im not sure what difference the meth makes but just figured I would share a little info.

I will soon have the bigger feed line and 75# injectors so I should be golden, but this is for you 630cc guys just to add on top of what 034 discovered running the 630s and upgraded fuel line. (they saw 12.5:1 at 25psi)

what is the point of this? to figure out fueling? You could just see where your target AFR is. If its not close, there is a restriction

im kinda lost on this thread, is it a question, a statement......?

not sure what your trying to say david.

It was to say that people that dont have wideband gauges running and are running high boost on the stock fuel lines and 630cc injectors should be careful since my car started to lean out at 21psi (it normally runs at 12:1 at a little lower boost). Like I said this was for people with similar setups they may be making similar power.

Remember that head of mine with detonation in 3 cylinders after some 25psi runs? Kinda makes sense doesnt it since at only 21psi im already creaping up to 12.6:1 air/fuel.

On my 22psi dyno plot the AFR averaged 12 to 6400rpm on 630cc injectors with 94 octane.

The VEI wideband/boost gauge is working great Winston
