You love to do things the hard way. Costs money to go fast, as you know. What we are saying is that do it right and it will be consistent. Think about it - you had that converter with the old combo, AFAIK. Now the combo is totally different, do you expect the converter to behave the same? Converter should always match the combo. It's gotta be an uphill battle trying to tune a motor that is fighting itself. I'll bet your data curves will look completely different with the right converter. Look at the pics you posted in your other thread - top left, the first two data inputs - engine speed vs. driveshaft speed, maybe kinda important ones? The first pic on the 9.79 pass shows a ratio of .52%!! According to your readout there, the DS was spinning at over 13K RPM. Thank Marty for doing a good job balancing that thing.  Now look at the 2nd pic, the ratio is more than 20% higher and see how much it picked up. Imagine if it was up in the 90% range...might not be possible to get it working that efficiently but you get the idea.  Don't mean to talk out of school here, just trying to point out that the blower does not overcome all maladies.

If you breach the 8 mark you might acquire a new alias for your self to be called 8Ball. 8Ball in the corner pocket. I will wear it like a badge of honor.Looking forward to the new licence plate bracket as well. Just might have that air brushed on the rear panel,,,,

I wannna know why driveshaft rpm would show higher than engine rpm. Something is sorta out of whack there.

That there is a super cool character logo. I can arrange a small color painting on the deck lid for you once you get there. Perhaps at that time, you can lease me some ET on a monthly basis.LOL.
License plate bracket? I would keep it al hush hushhhh and have a pool stick chalk at hand to hit it in the corner.
Itis, you ever heard of the two 64' SF/X supercharged Chargers? Basically, two 330 Coronets called Chargers. Spoke with Bud Fauble at length about them.After his 1st nitro explosion,he told them he would NEVER drive anything on nitro again!! Bud was a very cool dude and light on his feet! RIP BUD,,,

I should engage my brain before posting next time. If the converter was slipping DS speed would be lower than engine speed. Burnout is probably correct or tire spin somewhere during the run. Ask Al how much the tires moved on the rims by the end of the day.
Might be good to know at what points the data was taken from though since both screen shots show the DS speed higher than engine speed.
Sorry for the misinformation and for getting off track.

Screenshot was at the stripe.I never programmed the DS sensor,still tryin to figure it out.As far as the tire movement,I will try DVWs rec with the permatex.If that fails I will switch the street tires with the slicks so the beadlocks are with the slicks.
PF is set at 7,will drop to 6 in high gear.

PF is set at 7,will drop to 6 in high gear. If you mean fuel pressure, the data shows 3. something.

Itis. Is the first graph in the burnout box and the second graph through the stripe after shifting into neutral? That is low fuel Pressure. That was at the stripe,last pass om pump gas.That was at the stripe when I was on the binders it went 1,2,1,2  After I turned around on the return it came back enough to get back to the pit.I was outta fuel...... The other screen shot It went from 7 to 6.5.

Dom,I have several friends that are faster than me that don't screw the rims.DVW is a perfect example.Over the winter I will break these slicks down and clean them to re=do with the permatex Doug said to use.If I still have an issue then I will switch the rear rims around.
