did i do wrong?

in the video the run were I ran the white mustang just after the start it spun,i caught it early and got back on it.i see a back fire in the vid could this have hurt my ring lands?should I have just let it go not to beat up the rings and pistons?

hey larry nice pass! just watching the no mercy on youtube and seen your car and didn't realize it was your car! if you don't mine me asking whats the combo and tune with steve Johnson fogger system. what jets you running and how much timing you pulling out at the hit! got steves single fogger on mine to just looking for a starting point! will start off with a 200hp kit and a 8 spread !thanks and keep up the good work!

this is an all aluminum c&c block 580ci 12.0cr p-51 heads chambers reworked by buck racing.we were on a .038 jet at no mercy pulling 14*total from 28*initial 7*@3500 and another 7*@5500.

we just didn have time for testing before no mercy so I put the .038 jets in it and left it alone other than adjusting on the nms controller.

I would say could you hurt the ring lands Yes, did you apparently not terminally as your fastest pass was after that pass. My question is; I think you stabbed it back to the floor when you got back in it true?...My take (advise) would be that if you are going to take down the prize and you feel it is worth it stab it and take your chances, but when you dissect the events happening lets say using a RPM activated NOS kit/program when you let off the RPM doesn't drop below the activation limit so the juice will come right back on, the problem is the carb is slower to react than the NOS solenoids especially the NOS which is at 900+ PSI so the nitrous gets there BEFORE the fuel, if you are comfortable getting back in it use the funny car throttle depression method and push the throttle to the floor and let the carb recover before it gets to WOT and the NOS activation switch activates the NOS.

the runs were not in order, the pass were I got back in it was my last and sets unmolested from that run.i think I will buy a bore scope and check things out.thing is I really wanted to go to the second round and it just wasn't on my mind about getting back in to it easy lol......

my controller it set to were the fuel comes on before the nitrous but it may not do that when you resume from lifting.also the pistons are for "HEAVY" nitrous use hopeful theirs no damage.

How did the plugs look with that much timing pulled out? What fuel are you running?

I have a buddy with a P51 deal that did that several times. He was spraying heavy. Eventually a piston did let go a piece at the ring land but it was sprayed heavy for quite a while before it did. He was spraying a 52 jet I think when it let go but it wasn't a backfire pass when it did. He didn't know anything had happened until he pulled the plugs and the plug for that cylinder was beat up.

Also on your NLR, if you have it set like mine, it resumes where you left off if you get out and back in. You can set it to start the ramp over if you want.

the plugs looked great,we adjusted the timeing on the per cylinder trim until the timeing was just above the radious on the strap.im sure I could have left in 1-1.5* and got that 4.80 I needed to make the 32 field but that is hine sight....actually on the last qualifing run it needed moor fuel because of the moisture in the air.

I think that is correct were I last lifted in the program it will resume,this nms-1000 is a new deal for me its taking some time to get use to the all of the features.

I wish I had mine set to start over. Maybe my car would have settled back down a little easier. I whomped it but it "resumed" and kept coming up. Live and learn I guess.

What was your ramp if you don't mind me asking?

These Fords are more resilient than a Timex, as for the easing back into it, being top of mind helps but like anything else the moment comes first the "I shoulda" comes after. You built a monster I am sure it can take some punishment!.

i use C23 fuel it is expensive @ 100.00 per 5 gallons but I want to protect it from detonation if possible.the ramp starts out @ 30 percent and is ramped in @ 1.7-2.0 seconds.

That's a orange flame out the exhaust only that tells me it was( fat )gas build up in exhaust from a quick let off and right back in it....

Fwiw ive peddled mine a bunch w both guns a blazin and never had it pop or hurt a thing, my timing retards have an off time of 1.00 jut to ensure the cyls are clear etc before it adds it all back ... Idk

^^^^^this,,,, but I was under the impression that he has his set to pick up where he let out if that's the case it loaded up for that split sec.... I could be wrong just how I'm reading it

Larry how much does your car weigh. Car looking good in the video

3060lbs loaded with my tubby frame.....we had to put in 40lbs to make 3100 at no mercy.before the new all aluminum motor I had the cast iron ford motor sport block the car weighed 3250 with driver

Ten4

Larry what's the airflow on your heads int/ex

last year intake was said to flow over 450 average with a 6" bore adapter.no exaust numbers it dosent really matter when useing nitrous.
