    HP loss?

    so i was reading in the automatic transmission section and i saw a post that talking about the loss of horsepower experienced after getting a stall, is this loss experienced through out the rpm range? this guy was saying that they will eat 30-40 horsepower, so does that mean if i get a stall it will make my car faster at launch, but assuming i didnt stall it at launch, or i was racing from a roll, my car would be slower? 30-40 horsepower slower?

    thanks mike

    you lose a few horsepower because a stall eats some up. no way do you lose 30-40.
    your car will be faster.

    30/40 hp, I don't think it's that much, but you do lose a little. But I took 7tenths off my 1/4 mile times with a 4000 stall. So if I did lose that much hp, who cares, I went faster. As far as going from a roll, I can be cruising at 60 mph at 2500 rpm. and give it a little gas, I am at 4000 rpm immediatly. Thats right at the start of my powerband, and if I punch it, it sits you back it the seat. A stall is a proven way to make your car faster, regardless of what a dyno says.

    Wait I thought the stall only helps out when you race from a stop? IT helps on a roll too? Im a little confused, how do they work?

    Basically as I understand it, a stall lets you launch at higher RPMs. In something stock your tires would start to push you forward at a very low RPM if you have a higher stall the RPM it starts to activate the tires is higher. It is inherent in autos though that the stall will slip hp away especially in the range near the stalls limit since it is acting as a clutch.

    So it helps in both a roll and a stop?

    Honestly I have not dealt with big stalls from a roll much (me in the car) . It has been so long since I had to do anything other then drop a gear, hit the gas and pop the clutch.

    My first thought though is a stall should not affect you to much on a roll, but that would depend on the speed as well. Something like 5-10MPH you might still be right at the slip point, where something like 40-50 you should be out of any slippage from the stall.

    lets say you are in overdrive doing about 2200 rpm. when you gun your car and have a 3500 rpm stall, the car stalls up and jumps to 3500 rpm.

    also shift extension is another benifit to having a stall. it keeps the rpm higher.

    Ahh I see, I was always thinking it just helped from a stop. Maybe I should look into getting one.

    i understand that it makes the car faster, but the way you judge that is in a 1/4 mile strip, when you race in the quarter your car is stopped, i want to know if i am cruising and i punch the gas after i have a stall, will my car be 30 horsepower slower?

    No, your car will not be slower, it will be faster because it puts the car in a better powerband. If your are going 50 mph and step on the gas just enough not to downshift, the motor will immediatly jump to 3500 rpm, and you start building speed faster, instead of waiting 3 or 4 seconds for the factory stall to get you at the same 3500 rpms. You live in Florida, go the Florida member section, and see if someone close to you with a stalled auto will give you a ride. After you've rode in a stalled auto, you will be ordering one the next day.

    stalls are the way to go,they have been the way to go on high performance vehicles for many yrs.look at your responces,i think you need to check the source you heard that from.take your car to the track,then after the stall run it again and then you will see.oh and beware of the mod monster you may become an addict like many of us. haha

    Do stalls create an actual parasetic loss??

    I thought dyno's just read it different because of how the power comes.
