How can I adjust the air/fuel ratio???

Dyno

I took it to a Dynojet Dyno. Whatdo you think my RWHP and TQ should be about.

240-280 IMO i have a close set up to you and thats what i put down. well i assume those are your numbers with no spray?



Whats your timing like?

Timing

My plugs are .035 Autolite Plugs and my timing is 14 with the plug out.

.035 gap is really tight unless youre running some kind of power adder. Youd do better with .050 to .060... But get your fuel issue worked out first, that's KILLING your numbers and hurting the motor too, too much unburnt fuel can wash down the cylinder walls and cause the rings to start scoring them

Plug gaps

I was runnin 0.35 b/c I have the Nitrous but I really hardly ever use it. What should my gap be with no power adder. Should I just change the plugs when I want to use the Nitrous???

I dont see where you clarified what MAF you are using....

Correct me if I'm wrong, but I thought that the stock 19 pounders were good for around 300 horse. Other guys will chime in, but how about putting the stock injectors back in, and maybe also add the AFPR?

I read your profile and i don't see a Mass air meter listed as a mod, but i do see 24 lb injectors. Is this car SD?

And as said you do need an AFPR, since 24lb injectors are technically too much for your combo.

Updated with MAF

Hey guys I updated my sign with the MAF. Would all this extra fuel bog down my HP. I only dyno'd at 214????

And the MAF is cal'd for the 24's?

I would change plugs, get a afpr and go back on the dyno and have the tuner keep advancing your timing till you get a 13 or 13.5 but thats just me

+1...change plugs, gap to .055 or a little more if you dont plan to spray on em....0.55 I believe is stock gap. More gap will give you better power as long as you can sustain a hot spark between it...too little gap shrouds the flame. DEFINITELY get an afpr....seen many many guys upgrade injectors and run stock fuel pressure and have tons of driveability problems and never figure out why. The extra fuel can definitely cost power, lots of it if it's bad.

Air/Fuel Ratio??? and FPR

My air/fuel was done while it was on the dyno jet dyno. I'm not exactly sure when he got the exact numbers of 11.2. He ran the dyno and then showed me the computer...

Should this FPR be fine for all my fuel pressure problems?

Yep that will work.
