I'm hoping the next time I'm at the track I can break into the 9s, my tune-up was pretty rich as well, 11.0-11.5 afr. We will get these monkeys off us!

No no timing pulled on launch. I even pull my timing retard out progressively instead of pulling it out in one big chunk.
I would like to see it 60' in the 1.25-1.27 range.
4.11 rear gear.
I'm going to lean the tune out. Timing looked nearly perfect of where it should be. Timing mark was 1/16th of an inch from the bend.

At 3000lbs, With that rear gear and 1st gear in trans. I think it should go low 1.2x
Travel limiters?
Well you know the deal there, pull 1 or 2* out then lean it out.
It will run faster leaner with less timing.

Maybe I shouldn't pull that extra 2* out from 5600-6800rpm as it seems to flat line right there in that exact spot until it builds some rpm and is back to 17*.
OR.......
Should I just run it with 12* of retard from 5600rpm all the way until red line instead of putting that 2* back in at peak horsepower to redline I leave it out and lean it out a good bit.
Pretty sure the wideband said 11.5-11.7 last night but glancing at it with the front tires off the ground is kind of hard and once I hit 2nd gear I'm watching the rpm's and not the afr gauge.
I am going to try a 42 fuel jet next time out. Maybe even a 40 fuel jet. I have a 38 but I'm pretty sure that will be too lean.
I also have tossed around the idea of going back to the 82n jet and putting the 38 fuel jet in with it. That should put me pretty lean where I'd like it to be. Just something I have thought about doing as that jet combo should be right on,

Martin, I'm not sure if you got my text or not but I was talking to a couple of nitrous fast boys and they think your solenoids are to small and possibly the plate as well.

3600rpm I'm pulling 4*, 4000rpm 5*, 4400rpm, 6*, 4800rpm 8*, 5200rpm, 10* and I have all 12* out by 5600rpm and it stays at 12* of retard until 6800rpm where I have it back up to 17* till redline.

12.7 it will act like whole different car.
I like how your doing the timing.
With our old 396 and tight converter we had 40* in it until the converter started to "catch up".... what does yours flash to on nitrous?
my guess would be 5200ish, what we would do is not pull any until 5,000 then taper it out over 1000 or so.
Left on 200 off the button and another 250 in at .3

You really need to get your tuning software so you can log and make timing changes. Otherwise you are just guessing. Weather will play a difference as you know

.125 orifice nitrous solenoid and a .178 orifice fuel solenoid should easily be enough solenoid for 400-500hp I would think.....Wayne??

11.5-11.7 is still real fat.

Thanks for the compliment on the timing, but cam is the one I got the idea from. It locks up solidly by 5600-5800rpm and really starts to accelerate at 6000-6200rpm it flashes to 5400-5500. Can you hear it flat line once it flashes initially on the launch like I can and once the tires touch down it begins to rise? I know I can hear it, you think I should start pulling timing at 4400 and make a more aggressive ramp or start even higher rpm pulling timing?

Thats exactly what we do. not 40 though. 26-28 I think. flash is 5400 all out by 6000 as shift drops to 6200.

He was all on my *** last night for not logging any of the passes lol.
I need to get my buddy john out to the track the next time I am there to log it.

I'm going to get it leaned out a lot and see what it does. I had a pretty good yellowish fuel ring on 5 out of 8 plugs. Some had less than others but 1,2,3,5 and 8 had the most noticeable fuel rings.

Leaving the timing in will push the converter a little farther also which is good for you. It wont hurt anything to leave it in because there is no load on the motor until 5400.
Get it leaned out and work on the 60' ... it will come around.
Small changes ... dont do anything dumb. LOL !

if it flashes to 5400 then all your doing by pulling timing before that RPM is slowing the motor down and making less power.

Yea yea yea, money is just extremely tight right now.
I thought I had someone interested in hiring me for a well paying job I have always wanted but I have not heard from them in several days since they were supposed to contact me.

That would be interesting to say the least.
I guess I should at least keep the rolling chassis and just toss the motor
Should I start the timing retard ramp at 4800rpm Wayne with 4* retard or just wait till 5200rpm and pull 8* there? I think I already know what you're going to say, just wanted to be sure.
I think if I can get the car accelerating harder and faster earlier into the run then it will 60' in the 1.25-1.27 range I am looking for and the 3.75-3.80 330' range I am looking for to really put this thing where I think it should run.
I honestly think this car the way it is right now can go low 5.80's@116-117 with this size shot, I just felt like last night I had crossed all my t's and dotted my i's and now it sounds like I still have more work to do....
To-do Checklist:
Drag Joncr96z to the track with me next outing
Lean tune up out with 42 fuel jet if not 40 fuel jet
start timing ramp later.....4800rpm? 5200rpm?
Add second 93n stage before pushing into pond across from house
So this sound good?
I still am going to have my heads ported polished and milled and I am still going to put a new cam in it in the next month month and a half. I think the heads will make the biggest difference, but I'd like for the cam to match the new heads port flow.
I have decided on specs for the new cam and it will be 239*/254* .624"/.621" 115+5. LSL intake lobe Cheater HR exhaust lobe. I'm also really thinking about porting the heads myself as I have been watching a lot of cylinder head porting videos.
