Give your combo and then your timing and FP

[cobra dave]

For us doing the self tuning that cant quite afford a PMS or Tweecer lets get some fuel pressure and timing settings. Try and include your current combo in detail so some of the guys can can get an idea of how things MIGHT turn out.

95 Cobra

Stage 3 non-split matched p/p cobra intake
Stage 2 p/p gt 40 heads (iron)
stock cam
FRPP 24lb. inj.
Walbro 190 lph FP
Aeromotive FPR
70mm BBK t/b
c&l 76mm Trueflow system
Densecharger Deep fenderwell CAI
MSD 6al
Billet dist.
Blaster coil
Taylor Spiro wires
Autolite 764's @ .54
BBK underdriven crank, Alt., waterpump
Fluidyne big ass radiator...........
No smog or A/C or any emissions for that matter

Timing @ 10' and FP @ 45 psi wide open

I dont think I need to get into any more motor bolt-ons suspension, exhaust, drivetrain or any of that jazz. If anyone would like to see my entire mods list I can pull it up and you can sift through the pages. Had to do it for insurance purposes.

With THIS SETUP I was running 38-39# WOT with 21# injectors. I forget what the A/F was on the dyno, but the dyno operator at Crazy Horse said it was close enough to perfect for a street car that he wouldn't waste any time adjusting it. I've got the dyno sheet & A/F graph somewhere on disk. If I can find it, I'll post them.

Most mods in sig
Stock FPR (you can get away with them), set lash at a quarter turn past zero while running, plugs gapped @ 0.35,-4* on the cam, and timing at 16*.

Can't wait to get mine on dyno and get an AFPR but the plugs look perfect and no pre-det on the top end so I'm not to worried for right now.

Ever since I've got it running its been SOTP tuning out behind the shop (little 1/4 mile strip of dead end road) .

...set lash at a quarter turn past zero while running...

Must be nice to have enough room to get the valve covers off with the intake still on

See sig

Timing @12 but actually @16 (FMS extender adds 4 degrees)
FP: 41psi

that's a nice setup i made 280/306 with a very similar setup in 'Old SlowGT' in my sig.

I found the DYNO GRAPH. It was already posted. Still looking for the A/F graph.

 

[cobra dave]

Anyone else? I know alot of guys will apreciate this down the road.

I still have to take the upper off but since I've done a couple times now it only takes 5 min 6 bolts and a couple of turns with the screwdriver its off.

Thanks, I had some issues on that run though, I had exhaust leaks on multiple cylinders, and I think my maf was taking a crap on me. I think it wouldh have been higher with my issues fixed, but never got to dyno it after fixed, after that, threw on the maf, t/b, extender, cam, ect...(see sig) and now that I've moved, getting settled in, hopefully will have an updated dyno run.

 

[94gtslow]

p-heads, e-cam, cobra intake, 30# injectors

timing 10* fp 38#, all on 87 octane no detonation, made most power with itmade less with better gas and more timing.
