Do you happen to have a dyno from when you were running your old stall? Did your power levels stay about the same after the swap?

I'm planning on spraying the converter locked, atleast for 1 pull. probably around 550hp range next year.

Well ours is a single clutch as are fuddles and most others. We just havnt done any exstensive yet at high power with WOT lockup. As generally track times for most cars are actualy lower with the converter locked. But if there was no sign of slipage on the dyno which actually harder on the clutch than the strip I would say thats a good thing.
Generally though for people who want to lock on a regular basis not just on the DYNO at WOT its generally a good idea to use a multi disc clutch , I dont even think yank suggest locking at WOT with there converter either from post I have read. Im not saying you cant do it or that it wont do it but it could possibly shorten the lockup clutch life, You have to remember your asking a really small comparativly clutch to do the same thing as the ones in a manual car have to do and you know how much surface area and presure they have and they still die too

Like I said, I made other changes at the same time as the tranny/stall swap, therefore the difference would not be an accurate comparison.

Although I can give you a locked/unlocked comparison.

440/425 unlocked
480/460 locked

492/445 unlocked
511/500 locked

Different power levels but you can get an idea of efficiency maybe?

Interesting, I look forward to seeing your track time etc . Thanks for posting this.

Actually we started selling and making our own to reduce risk since while we have had a couple other peoples converter take out or at least clog up our trans with crap which we still took care of our customer. We have yet to have one of our converters to fail , Not saying it wont happen because anything mechanical can fail but so far at least its been a good move for us.

Yeah thanks 24v, definately some good information there. Looks like a pretty solid and efficient converter based on that comparison.

492 v 511 HP puts the converter in the 96% range, which is pretty efficient. I'd be pleased if it were mine.

Here ya go! Sorry for the huge blurry pic, but I think you can get the idea. It shows the converter foot resting on a weld. This pic was taken before I broke out the die grinder and took some metal off of the back of the foot. Since the welds don't go all of the way around the flex plate, I also considered reindexing the converter and drilling three new holes. I didn't have a good drill bit, so I opted for the grinder instead. Like I said in the earler post two out of three of the feet looked like this, and the third one barely cleared.

humm maybe that was jsut a problem from the factory that the welds were so thick

Considering their purpose the welds don't look overly bulky, in fact they are kind of skimpy. That's why I chose to grind on the converter instead of the welds.

The bolt hole on the right is the one that lines up with the hole in the flexplate. The factory converter foot centered up on that hole, wich kept it away from the welds. To me the problem seems to be the extra metal required for the bolt hole in the new converter, that is offset to the left and a little closer to the outside.

I was looking at a few flex plates we have and some have the weild at that index other at another location, Anyway either solution should work when it arises

quick question for peformabuilt again. I may end up going with a torquer v2 cam over the 228R, between the 3k stall and the 3200, how much will the driveability be affected comaped to the 3k and do ya think it will be enough for the toquer 2?

performabuilt

iTrader: (25)

drivabilty is not that different between a 3000 and 3500 with our stalls , But while 3k would probably be enough 3500 would be more fun , but I will say this again since many dont know you can get any stall in our 9.5 inch from 2600 to 5500 pricing structure works like this 2600 to 3000 priced as 3000 3100 to 3500 priced as a 3500 etc etc .

iTrader: (9)

I may go with a 3200 then. I jsut dont want to run into problems running the torquer 2 but dont want to big of a stall but if yalls converters are as tight as you say they are I dont think ill mind the 3200

performabuilt

iTrader: (25)

No you will be very pleased with the drivability , at that stall

Guys, I would go up 2 sizes on the stall from what you think you want. I am wishing I had bought a 4000 instead of the 3500. I had a fuddle 3200 in the car, and it flashed perfect at the drag strip. I feel the new 3500 is a little too tight for what I was looking for. However, other than that, I love the tranny I got from performabuilt. Great deal, and a great shifting tranny.

That is basically how I feel with my 4000, It is pretty tight.
