What exactly do these do? What are the benefits on an otherwise stock car?

 

I have one of these units and it is very nasty. What is crazy is that you dont feel the lag like you would expect from a higher stall conveter like this one.

It is much easier to build rpm from a stand still until you push through the brakes, for example I can rev the car up to close to 3K before it starts pushing through the brakes, so launching is much more violent.

Doing slow role pulls or even highway pulls is much imrpoved, as yo feel like you are been catapulted forward.

 

recommended for daily driving?

 

+1 on recommendation for daily driving

 

feels the same at stock.
if you punch the throttle you will have fun at 3000 rpms

 

I want.

 

Nice description!

 

it will feel like the trailer of off the back of the car it will just go from any rpm and part throttle stop go driving is way better. Stock pulley 2nd gear burnouts from a roll yup i have a 3000 stall.

 

Any downside to this in the long run? Maybe some wear and tear for the other oem parts?

Any benefit to this if you already have an LSD?

 

Weren't there issues with tuning with higher stalls in these cars? How are trans temps? Would an additional trans cooler be a good idea or is the stock setup able to keep this in check?

 

i doubt you will see much increase in temps unless you in alot of stop and go traffic and your flashing the stall, if you drive normal you wont know its there really

 

I have had zero issues with the stock trans cooling and zero issues with tuning the car with it in there.

Just what Tim said, with normal driving you are not really aware it is there, only when you start to get aggressive will it rear its nasty attitude lol.

 

Sounds great ... but there has to be downsides , just like every mod. What are those?

 

Mpg and heat are the downsides. Might be a couple mph lost in each gear also since the ratio of rpms at the drivetrain decreases relative to engine rpms..

 

if its a downside forget out getting into first and 2nd gear because your going to blow the tires off. Trust me a pulley on a car with aircharges in the 150's and summer heat is way worse then a stall.

 

Summer heat, plus stall? Without a temp gauge one can only speculate. My last car was a small displacement big turbo auto with a big stall. A single quarter mile pass and I can see temps just below 300, after the coolers! Yes, plural coolers.

It just depends on use and capacity of existing system.

 

I don't get this. I would think due to the lighter weight and less parasitic loss, if anything, mpg would improve slightly.

As for losing mph in each gear, I don't see how. It isn't changing the gear ratios.

 

you are higher up in rpm so mpg would most likely decrease in city driving where the torque converter is not locked up.

losing mph possibly because there is a larger gap between engine rpm and transmission input speed

 

You are correct Dennis. Rule # 1) These are locking converters and they lock up using clutches, same as stock,,, plus these performance converters have more clutches added, so they can lock up harder. So less slip = , well you got the picture. You will not loose MPH in each gear; please see rule # 1. You will gain MPH in each gear at WOT and in the 1/4 mile. You will average more HP in each gear as an average under WOT, thus go faster and have higher MPH. We have big heavy cars and the extra stall is a big help in helping them move.

Since they are locking converters, this is why everyone states the converter feels stock, until you lay into the gas and unlease the raped ape! Now under WOT, MPG may drop but that is what more power and TQ do at WOT.

 

Schino is correct. The loss of MPH in eache gear would be relative to each gear, the higher the gear the more multiplied the loss would be but only while the TC lock up function was disengaged. I'm not aware of the programming of the lock up function in the E55 but most transmission dont allow/force lock up under a substantial load. What does this mean? If you were currently topping out a gear hitting the traps, you may experience an upshift. Inversely if you were in the middle of the gear, you might pick up some MPH by avoiding a shift. While cruising, thing should lock up as usual and net similar mpg and mph.

However, the stall on my previous car was too great for the programming and confused all the parameters in my TCU. It was so bad that I manually wired a switch to control my lockup function but I doubt any thing like this would be necessary in these cars.

 

anyone care to share if we have wot lock up. most cars wont let it happen because standard clutches wont hold but im new to this platform. the stock converter is too tight to realize if its locked or not and my logger doesnt do trans input speed or tc slip values

 

It's wouldn't be difficult to add such a feature, should be able to compute between gear, wheel speed and RPM.

But yeah, most transmissions also let the lock go between shifts as well.

I emailed John at IPT earlier today, hopefully he can provide some insight on the E55 AMG lock up function and its programming.

 

Any chance you know the K-factor and torque numbers used to determine the 3K stall? I've read previously that these will work just fine in a n/a 55 but I'd like to know what the stall would be with my lower torque curve.

 

Is there something like this for an ML63 W164?, I hate it when I mash the gas and I feel the tranny slipping, it sucks!

Any idea if there's something for ML63?
