Converter multiplication ? - Page 2

K Stubbs · 02-22-2011, 01:12 PM

I got mine from A1, they asked for a dyno sheet and got it. I will see how good it is but I have alot of confidence in it. Dyno sheets are important and so are the numbers on them. If they are bogus that will be a problem but they should have enough "sheets" to compare them to. What is more bogus is writing your info down and them "assuming" that your combo makes x amount of power. That is saying that every person with the same combo makes the same power. Doesnt mean that they cant get you in the ballpark or hit it right the first try, but numbers are important.

I've sold probably 200 of their converters, and don't remember having one be too far off. There are no "off the shelf" race converters from ATI. Each one is custom built to an individual application, from all new parts.

I had a problem with one ART did, all others have been dead on

Why, that ain't no super stock car.

That said, none better IMO than ATI!

Those that think they are, I invite them to step up

The PROOF IS IN THE PERFORMANCE

3124 lbs. n/a and a best to date of 1.17 60 foot launched off the footbrake.

yes I know its not a SS car but looking to get it to leave a little better. What ET and MPH are you running? Can you post some more specs on your car? I like ATI, no complaints, just curious of the info I was hearing.

If you have questions as to whether your current converter is optimum for your combo speak to Charlie Plott at ATI.

Be prepared to provide him with factual data, including but not limited to what does the converter flash to on launch, what RPM does it fall back to on the gear change(s) and what RPM is it crossing the stripe at and the only way you'll know this is with a playback tach or data logger.

As to my car's specs...

522 BBC, turbo400, 4.57 gear.

Slowed to run low 9.0's all season long at near 150

More importantly what are the specs of your car/combo?

Pump gas 383, glide with a 1.80 gear set, 5500 stall and 4.56 rear with a 29" slick and or a 295 drag radial. I shift at 7200 and run through at about 7000. That T400 gets you going with the bigger 1st gear.

If you think a turbo 400 "gets you going with the bigger 1st gear" why aren't you running one?

what is the best and average ET, MPH and 60 foot and at what weight? Also how many passes on this combo as it now?

Need all the details of the car/combo to determine if it's running near optimum and if the converter is right.

The devil is in the details and if the combo is mismatched, you'll never get the 60 foots you're looking for regardless of whose converter is behind that engine.

Did you read this...

X2, Got to agree with ED there

Charlie Plott was the only one who could get my converter right a while ago, They kept it @ 4200-4400

Charlie looked at it and mentioned some ss cars, took the converter @ no charge and brought it back and said its loose enough and has the proper stator now

When in doubt ask for Charlie and if he is busy leave a message

One of the nicest guys out there. Art is the one who specd it @ 4200-4400
