i ran like crap wonder if it'll make a difference if i add a feedpipe to the blower.Quote:

And I'll post mine from when I ran earlier in the year. :pQuote:

14.7:1 is stoichiometric. My opinion is that you should max at 13.5:1 at full throttle for power unless you are doing a racing car where you will be checking pistons after every few races. When cruising, then the A/F ratio goes closer to 14.7:1. Other engines like in the Jazz can run higher than 14.7:1 when cruising. I think. I have run on 2 different dynos, car was the same both times. One returned 10.5:1, while the other said 12.5:1 with a dip to 11.8:1 around 5000-6000rpm. So I can't tell which is the proper A/F that the stock car is meant to have!Quote:

It was hot as hell with 36 degree temps when I did mine. Not too good for dyno readings I dont think (I wonder what it would read on a cold winters day?). I'll post my sheet soon as well. On my sheet, I only have A/F ratio as well, and the line on the graph has a sharp drop halfway on the graph as speed increased for some reason.
Yeah around the same as you my face was burnt afterwards.Quote:

My power was pretty linear up, no sharp drops.
Btw does gearbox mods and clutch + flywheel make a different with power output?
You'll probably see the same drop on our charts too. Here's mine:Quote:

Flywheel doesn't increase the peak power, but it should increase the torque and hence power at low and middle RPM.Quote:
