Wanted to share with you my results I got yesterday.

As always it was a blast to head to Mason Dixon, MD for some good racing with Corky and Jim (85vet) and their wives.

This was the first time back to the track since mortally wounding my D44 carrier and having my stall converter upgraded to 4200 Stall.

I worked my butt off Friday night getting the car put back together. Took it home from the dealership for a shakedown run ~5miles with the new converter and rear (thanks Jburnett) for the cryo treated carrier. All was good. The car with that converter stall is UNREAL! At 35-40mph with slicks on the street it will break them loose! I about crapped my pants. Not to mention I probably woke up a few neighbors at 1am testing it out. I was also VERY surprised that street driveability is actually no different than before. Which I was sorta worried about with going this high. Anyways off to the track

It was the mean street nationals there, so the place was packed.

For the first run of the day I left the converter unlocked as instructed by Vigilante. Got out of the water box with a good burnout and no report from the rear differential so I was pleased with that Got to the line and staged.
Came off the line at about 1200RPM just enough to get the slop out of the rear, and get the motor off its ~900 RPM idle. Man did that sucker hit nard when I nailed it! Cranked down the 1/4 like no other. Got to the end and figured for SURE it was a 10sec pass. Here are the results from that run:

R/T .627 (must have fallen asleep)
60' 1.481
330 4.467
1/8 7.017 (new best)
mph 95.93
1000 9.223
1/4 11.112
mph 119.72 (didn't like the looks of that! Said I was going to go against Vigilantes advice and lock up the converter)

Second run with the converter locked....

R/T .537 (still asleep...left at about 1800)
60' 1.496 (Not as good as the first run..crap)
330 4.484
1/8 7.003 (new best)
mph 96.62
1000 9.208
1/4 11.074 (new best ET :cheers
mph 121.17

The shifting of the car is totally different now, in the sense before I could *hear* when to shift, now all that is messed up with the new converter. So I am a little behind in my shifts. Probably a lot behind actually. ~300-500 RPM off I would say. It *feels* like a whole new motor with this higher stall. I got very used to the other one after a zillion passes. Got to the point 1/2 the time I wasn't even looking for the shift light, just new where to shift. Usually my runs were within .001 second if comparing 60' =>1/8 mile =>1/4 mile intervals. Now its like relearning everything over again.

The first round of eliminations I dialed a 11.00....as Corky said putting the 10.98 would be a jinks, so I entertained his superstition and dialed flat 11.

The one A-hole official sent me to the other lane (wanted to keep as much the same as possible for comparison), after having a few choise words with him in the staging lanes, I got to make my run. Corky has been getting 1.44 60' times leaving high in the stall, so I thought I would try it higher and see what happen.

Dial 11.00
R/T .634 (WTF and I doing...this day was my worst light all year long)
60' 1.488 (after this 60' time, I am convinced I am better off at a lower RPM launch..If I would have gotten a better 60', it would have been there)
330 4.456
1/8 6.964 (First sub 7 eighth mile! :cheers: :thumbs
mph 95.61
1000 9.164
1/4 11.026 (new best ET :cheers
mph 121.02

Man that was soooooo friggin close. Again I hosed up my shifts...lol....the friggin motor in this thing is just screamin with this converter in it....I don't hear the climbing RPM anymore...so I am going to have to lower my shift point to about 4700 RPM so when I miss it, I am at about 5300 till I get used to the car again

But dang that was close. The bad news is I got eliminated by .02 sec...Dangit. Without a doubt if I would have gotten one more run, with the lower shift point, I would have gotten the 10sec slip. But Oh well. It will give me something to work for next time out. Made some nice gains across the board with the car this weekend with the mods done to it. I have a few more tricks up my sleeve, one I know will gain me some ET...so stay tuned for more to come! :cheers: :thumbs: :lurk:

Also I thought it would be important to add...if your looking Precision Industries....YOU do not know dick abou your own product. Locking it makes a world of difference. Why you would tell people not to lock it, is beyond me. If its because of longevity...then tell them the risks and let them make up thier own minds.
:mad

 

So still no 10?.
Maybe it's just one of those Zillion of things you've mentioned.


Slicks, street, 1am, waking the neighbors?, somehow I missed any efi content in that. Sounds like you're just out to give Hotrodders more of a bad name. The sport's taken enough hits lately, no need to just make the situation worse.

EFI Content:
If you want to post a data logging of one of your runs, I'll look at it for you, and maybe I can help you get the tune better. Must be heart breaking being so close, and not getting a 10. Hmm, but you gotta promise to act more responsibly.

 

GRUMPY I THINK WHAT GIVES HOTRODDERS A BAD NAME ARE GUYS WHO THINK THEY ARE HOTRODDERS THAT ARE REALLY PRETENTDERS
REAL HOTRODDERS ARE GUYS THRASHING TILL 1AM IN THE MORNING TO MAKE IT TO THE TRACK THE NEXT DAY NOT GUYS TAKING THERE CAR TO THE TRACK AND NOT RUNNING IT HMMM

 

Yeah that is my scenerio:

Grumpy's scenerio:

slippers, arm air, in bed by 9pm, blabbing his mouth to forum members? Lots of pertinent EFI content there.

Again please refer to You know you could probably just change your avatar to that little guy, then when you wanted to reply. You just put see avatar. I would save you a who lot of time.

Back to the content: I am extremely pleased with the results of the converter change and outcome yesterday. Sure a 10sec pass would be good, but we still have a few more weeks and a late november race in Jersey if weather permits. Some more playing with shift points and TC lockups, which I will explore further...will possible yield some more gains. :cheers:

 

Yep, the pretenders that blast thru their neighborhood at 1 am sure are giving the sport a bad name.
Proper planning will get you past the 1am thrashing.
Some of us have outgrown the need of having to prove ourselves on the track.

 

I offer to help you out and look at how you respond.

Tell ya what, thou, promise not to go racing thru the streets like some pretender, and I'll still look at a datalog and try to help ya get that 10.

 

Whatever makes you feel better, you just keep telling yourself. I think a few of us know why your desire is not there...it happens with most people that try something and fail...oopps I might have let the cat out of the bag.

As for tuning my car.....yeah keep dreamin. Funstick I think it was a while back said in a post to you he had a guy come to him after you supposedly tuned his car....His question/statement to you was something to the effect: "Grumpy. What the **** were you thinking."

That is really about the only documented/confirmed claims to your tuning ability that are here on this board. The rest is just

As for my own. There are many documented testimonials here and at other boards of my tuning ability.

You keep working on that bench tough....even a blind bird gets a worm every once in a while

 

For some, there is more to tuning than WOT at the track.

Some of us even like to use our rigs AND keep the smog police at bay.

 

Ive only jsut recently began browsing this end of TGO so forgive me from being out of the loop sort of speak...

Just purely out of curiosity, ski, how much work have you done with the ecm to get the maf tuned in? What have you done so far? Seems like it would be a pita to tune with the MAF and the LV8 with a combo that hot. My friend has a monte with a maf vette engine and he wants to do some tuning but i dont think either of us could figure the maf out on our own.

 

Guess we enjoy the same pleasures....except I don't have to smog police to worry about

 

 

What a bunch of BS, your story telling is getting to be absolutely nonsensical.

 

Yeah OK....it was in the thread from itsjojo, but that was deleted.

I'm sure some recall the posting....

It really did not come as much of a shocker to me....pretty obvious when you look at the entire picture. And that entire picture can be summed up as

Guess I am just not as dazzled as the people at your local strips are with your illussions of grandure. I mean opening up a computer and connecting it to a car are mighty compelleing as evidence of your abilities. But as long as your happy.

I guess I base mine on a little more concrete evidence and someone else commenting on your tune are, how should I say....PRICELESS.

 

You know, I keep looking and looking, and I've yet to find any DIY PROM content to this post. Nothing but chest beating whining from a spoiled kid. Well. it is humorous.

RBob.

 

Its gotta be like salt in a wound for a few I realize...sorry.

As for the spoiled, yeah my wife treats me pretty darn good...was she on here again lookin for Christmas gift ideas for me? Told her to not do that...but oh well.

PS: Look real hard, there is a little hint about Torque Converter lockup in that post that might help.........

OH Darn what was I thinking....there isn't one of them on an ECM test bench...Sorry for pointing that out to you. But for some others that frequent the strip, it might help out if miss instructed by vigilante upon purchasing their converter.

 

Oops, tripping over that ego again. . . Have to watch for that.

RBob.

 

Ski,
To make it more interesting and usefull for us diy prommers, what changes were made in the prom for lockup, and how did it help your times?

What other prom changes did you make to get your car to go so fast!! It doesn't help us all if you keep all your tuning a secret

Greg.

 

Locked for obvious reasons (because I am a big, bad, power hungry horrible moderator ). Don't worry - the other post like this is locked too and has the same exact text. Works both ways as usual. Jesse eggs Bruce on in his thread. Bruce eggs Jesse on in his thread. Both should let go - but, alas, we're back to where we started (and not too long from when both of you were on probation). Ho hum. If the lock brings emotion then drop me an e-mail and we can talk about it there ... but, these are rediculously obvious with all the smack flying around in the context of the now old but never dead Grumpy-Ski conflict.
