Was a little busy today. In FEB Dewey and I went to a dyno day at a local shop in the 'couve and I put down 285rwhp and about 304lbft on a mustang dyno.
Went back today, spent an hour, turned out 310rwhp and 314lbft of torque. I'll pay $102 for 25 HP anyday. That's $4 per HP. Not alot of mods can do that
Don't mind the AFR bouncy, the WB was set ultra sensative, and there isn't anyway to change between those cells in the computer and it's linear. With the noise turned down it's smooth like the first one was.
Then decided to tackle the race car aspect.
Just need to hook up the senders, get some BLUE condoms for the light bulbs so they aren't RED.
Fuel pressure gauge will be on its way shortly, see if I feel like spending that $$ to get it before the dyno or not. _________________ A redline a day keeps the carbon away! |

Good deal young Jedi... I'll pay $4 per hp any day of the week.
The RED needles and the RED lights look good - I say leave it

Or.... not
The needles are more Orange. B is right. Besides, my lights I like to have a blue hue. Being a white car I get the best of both color worlds. |

| That's a decent gain, what changes did you make to it? |

Fixed the AFR and took out 2º of timing.... total is 34 now instead of 36.
With the 3000rpm stall, when you mash it, timing is all in and it's just a matter of fueling. |

| How off was the fuel before? Would you attribute much of the gain to the timing change? |

lol! Me is dumb.
How was the shape of your timing curve looking? All in by torque peak then flat? I've got mine at 29 deg right now. Could probably use some more, just need a dry road now to play with the G-tech.  |

Started going downhill from 34. Went down to 30 and was down about 15hp. Timing didn't do nearly what I thought it would.
Everything is in from 3k on. flat curve
I run 29deg at idle... and when you mash it with the stall it shoots right to 34. |
