Test of ARAP.... was 165 MAF computer

[Marteney, Steven J.]

What's your truck weigh?

I have a feeling my timing is too far advanced and killing power, couple
with a rich running engine so it doesn't detonate.  Or I'm dropping a
cylinder but the engine sounds and feels smooth all the way up.  I can
DEFINITELY FEEL the torque down low so I know it's better than stock but it
just hits a wall.  Part of my performance problem is traction, but Street
Dyno doesn't care since I do a rolling start.

I like the street dyno software.  Well... it is hard to use and feature poor
but it gives me a real idea what's going on.  It's buggy though.  I'm
programming my own Win98 1/4 mile simulator so I use the points generated by
street dyno to feed the sim, especially since I don't handle flywheel torque
yet.

FWIW...

I ran my truck again last night - running mildly altered ARAP code.  Got a
16.5
@ approx 80 mph (as reported by my monitoring software) - pulled 181 gms @
4800
RPM @ 49mph.  GMS began to drop a little as I climbed past the 4800 mark.
As it
shifted into 2nd it dropped thru the 4800 mark, gms hit 180 again for a
split
second (kinda neat seeing this sort of info).

I'd sure think a built 350 should draw a whole lot more air than my old worn
out
stock 305.  Bearing in mind that this is originally an '85 engine, so it has
a
little more "wild" cam than the 86 and later 305 autos.

Question, how do you like the street dyno software??

Thanks
Gabe
