Torque Converter?

[Marauder131]

Hey Guys:

I've recently been reading that quite a number of owners have put in P.I torque converters with a significant increase in performance. This particular modification sounds intriguing and seems to be a good bang for the buck. Would the upgrade to a Stallion 3000 increase wear on the drivetrain though, as opposed to the stock set up. I assume in such a case, that the increased performance could have a trade off in the long term, no? Also, in addition to the torque converter, are any other upgrades manditory with such a change?

Thanks

PI is an awesome company, and I've had their purple torque converter on ALL my cars since they introduced the 9.5" lockups. Incredible mod. I really see no downside. The performance increase is dramatic. You will have wheelspin with 3000 stall with street compound. Your shifts might feel (but not really be) cushioned. It wouldn't hurt to add an auxilliary trani cooler.

I would assume that the potential for increased wear with such a converter would be dependant on ones driving style. One must specify pon ordering if the converter should be locking or not? A transmission cooler is not a prerequisite though, I assume. In other words, devoid of one, there should be no problems?

You can have your cake and eat it too! I would call PI and speak to Jack or Terry concerning your setup to determine what stall speed would be best. They will give you one free stall speed adjustment. The lockup feature will get better fuel economy. The single disc lockup clutch will lock the softest, and the multidisc clutches will be harsher but hold up to drag racing better under certain circumstances. Coolers are always good advice, and are inexpensive. I wouldn't expect too much more ATF heating with these converters if you are reasonable with the stall speed. It will still creep a little at traffic lights when you let off the brake. Drivability is unbelievable. Don't go overboard with the stall speed -- again, talk to the guys at PI. They set me up incredibly well on my 89TTA, as well.

I have a used one for sale. PM me for details.

I have had one for 60K miles, no problems.

There is a very well mechanic at work that I trust, not to say I don't trust you guys since we all have modded MM's here. He thinks I shouldn't put the T/C in without doing a bigger tranny cooler and a deep tranny pan with it. What do you guys think? :poke:

[ctrlraven]

I would at least do the deep pan. That was one of my first few mods, a Art Carr deep pan, adds 2 more qts of fluid, cooling fins along the bottom and the best feature a drain plug! lol

I had the same concerns, but in correspoding with Lidio, he stated that he did not feel an aftermarket trans cooler was necessary, that the stock one would suffice. It couldn't hurt to install one, but if it isn't a prerequisite, I'm going to hold off and just install the 3000 converter.

The OEM Trans Cooler is massive.

It also throws heat on to the radiator.

I have been drag racing my car since 2,500 miles and now have over 84,000 miles and 180 runs down the 1,320'.

At 20K miles I went w/ the 3,000 PI, added aftermarket cooler and deep pan w/ Art Carr trans kit by Dennis. At 40K miles went w/ S/C.

Now have Heat Exchanger & aftermarket trans cooler throwing heat on radiator causing high temps when ambient over 80* and speed 20-25 mph for over 20 minutes.

Removed aftermarket trans cooler, removed OEM trans cooler, remounted power steering cooler to front sway bar and installed aftermarket trans cooler behind front grill.

Change trans fluid once per year. Fluid changed 14 months ago, checked and red w/ no odor.

It is not necessary to change pan or add a trans cooler. Changing pan will help if you are drag racing.

Any durability comments are :bs:

[Raudermaster]

Thanks for the replies. Will just install the T/C alone then.

[Marauder131]

I've got a 3000 P.I converter on the way, and I'm looking forward to the results. In addition to the 4.10's and tune, it should be interesting. The 5.7 hemi chargers around town should be forewarned.

At least go with the bigger pan. It will help cooling and as said before just having the drain plug makes life much sweeter.

I agree!

The converter is SOLD.

I may have asked this before...but I am seriously considering installing a 3500 T.Q.
After reading through all the search notes here on torque converters it seemed that the preferred one was 3500...;)
Am I missing something or is it just personal preference...why go with a 3000?
Keep in mine that my Marauder is a daily driver....:D
Thanks, Architect

My daily driver has 3500 + 4.10=:banana:

I do 300 miles a week no sweat.

And it's a 13 second grocery getter. Plenty of street trees while I am out on the road. You should see the look on the ricers face when he just got pwned.

[sailsmen]

I drive 20K per year, go w/ 3,500.

We started w/ 3,000 and then switched to 3,500.

Some say when cars were carb and trans were mechanical and T/C were designed on a napkin say anything over 2,500 ruins the driveability. Back then there was no driveability to ruin!

[Architect]

OK folks...that settles it... I see a 3500 in my near future...
Birthday in June...ah yes maybe that's it...;)
I'll check with Dennis and see what he has....
Thanks for feed back...:beer:
