HP loss?

[Mr. Luos]

first time i ever seen a mod ask a question

Always learning.
Automatics are something I know a little about, but not a bunch. My car is an M6.

ok....by parasitic loss......its losing something in order to gain something...what gain?

[Mr. Luos]

Being in the powerband instead of having to get to it.

A stall (depending on speed) will allow you to launch at a higher RPM. This also goes for roll racing. Hit the gas, the motor is allowed to get to its stall speed instantly.

woa...thats sweet...i hate waiting those 2 long minutes for it to reach wot....jk...ill eventually get a 3500

[t-rock]

dude whats that pic supposed of in your sig?is that you?

[ArcticZ06]

wont a 3500 or 4000 stall appear to make you lose a lot of horsepower at lower rpms from slippage? It pretty much isnt locking up until it hits the stall speed so any hp ratings on the rpm range below the stall speed on the dyno will show the slippage right? I dunno, does that make sense?

['00T/A]

no i dont think this is correct, according to something i read it will lock up before the stall speed

[Vertiviper]

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.

When you gun it in an auto that happens anyway....same as a 6spd when you down shift you're gonna be at a higher rpm because the gears are spinning at different speed

you must have never driven a stalled car.
yes it happens stock, but at a lower rpm though. the stall raises the rpm.
say when you gun it on a stock car, the car will kick down to 2200 rpm. now have a 3500 rpm stall in there, the rpm goes no lower than 3500.
stalls put you in the powerband alot faster than an auto ever would.

[nhraformula]

Do stalls create an actual parasetic loss??

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

at higher speeds you can somewhat feel the loss because of the non efficient design.
