HOW To ADD 30% HORSEPOWER Using PADDLE SHIFTERS!

[redcarsonly]

Not a spammer. Just thought it would spark a good discussion: which it has. This what the off topic forum is for: discussion of off-topic yet relevant car stuff.

Furthermore, when I say a 30% Boost I'm comparing that to accelerating in normal drive mode and using your Paddle Shifters in manual mode. In normal drive the mode you shift at lower RPMs. Using your paddle shifters you shift at higher RPMs redlining your car before the next shift to 3rd thereby adding HP/torque. 30% approximately.

Let me know if I'm missing something.

And this is why I like to give people the benefit of the doubt.

Thanks for chiming back in and I'm looking forward to your future posts.

I think you're good to go!

Now where can I get paddle shifters for my truck?

I'm a little confused. How does paddle vs. stick ensure you shift at redline? Is there some reason I can't shift my stick at redline? You also seem to be implying that power and torgue have a linear relationship with RPM. I haven't looked in a long time, but I recall power/torque curves being more bell shaped.

Shifting at different RPM's doesn't add HP/Tq...HP is calculated by multiplying Tq by engine speed...higher Redline shifts won't increase that. It may feel like more HP im the "butt dyno" but it doesn't actually increase it. If that was the case all cars that have higher red lines would create more power that you challenger, period.

Go get a real dyno completed using your normal automatic shifting and then do it in manual...it will NEVER be 30 more HP....

I am strictly talking about automatic transmissions not manuals. Automatics have rev limiters that are purposely designed not to shift at the red line. Paddle shifters are an attempt to mimic a manual transmission. The video explains how to shift an automatic using paddle shifters in lower gears for an added performance boost.

The video explains how to shift at higher RPMs for added performance compared to not shifting to at redline. Comparing the two options the former will shift with 30% more HP/torque compared to the latter.

I'm not going to sit and argue with a wall. I know where you're going with your thought process but it's not being worded correctly. I drag race semi professionally and have an automatic with paddle shifters....I never get more power using paddles nor do I use them at the drag strip.

Just get your car professionally tuned since I'm guessing you know nothing about using a "true tuning program" like HP Tuners (not a portable unit like SCT, Hyperchips, or Diablo) and in auto without paddles your redline is higher anyways.

Still confused. Any reason I can't just shift my automatic with the lever vs. a paddle? Also think this makes assumptions about automatic trannys that are not entirely true, esp in high end cars and esp over the past 10-15 years.

I'm NOT saying that if you had two cars with the same powertrain and one had Paddle Shifters it would have 30% more Power than the one without.

What I am saying is that the car with paddle shifters can shift at a higher power range than the other. One shifts at 130 hp and other 100 hp. Both have 150 hp (just example). The car with paddle shifters would Not flat out have more overall power. It just uses it better.

Every car, I've owned or driven, that have been automatics can select gears and hold till "redline", and then the computer would command the shift. I have 4 cars outside that can do this. Our honda oddessy will bang off the limiter if you don't shift it from 1-2 if you have 1 selected, quite fun for a van. I don't think I've ever seen a car that dosnt go to "redline" every gear when you go wide open throttle.

Do some research on power curves and power bands and dynos. higher rpm sometimes means a slower car. Only a dyno/track testing would be able to tell you if you have real world gains from moving your shift points. Results might surprise you.

All your really talking about is staying in your powerband, and your right, thats racing 101.

Hmmm, my brother in law has a '16 Camaro 2SS and one of my best friends has a '15 C7 both automatics. They get a lot of trash talk from others about them getting automatics over manuals and both of these cars are idiot proof on the drag strip. Both cars are .3-.5 faster going down the track while being in Track mode than using the paddle shifters, the SS ran 8 runs and all 8 were between 12.20 and 12.50 in the 1/4 mile while in Track. He ran 6 runs while using the paddles and ran 12.5 to 13.1.
Today's software and auto's when working properly shift faster, use the torque band better and when you throw in launch control (especially in the Camaro) are consistent run after run. From my experience in the new GM's, GTR, BMW's just leave it in D and hammer down.
I think the OP would have more ground to stand on if he would have came from the around town paddle shifters provide more of a personal experience angle but I don't buy the hp claims. Now I don't have much experience in a DSG type auto but on modern regular auto I'd say let the computers do its thing

Valve float is an undesirable phenomenon.

I agree, just because it's making more noise doesn't mean it's faster

 

[adamgayton81]

Even if your banging the redline, when you look at a dyno chart and compare the HP equation I mentioned earlier you begin to lose torque at a certain point in your RPM. Like others said it's a bell curve, you may be hitting 7k RPM (just an example), and it sounds and feels like more power but you lost all your torque around 6k RPM.

DSG's function the same way; put it in D and let the computer take over. The only difference would be in the aftermarket tuning of them. I have the latest version of APR's DSG tune and it's about .1 to .2 quicker in the quarter mile if you shift it in manual mode using launch control. Using manual mode at the track, they have modified the clutch pressure to squeeze out a bit more grip thus better times. I pass on using it only because I don't want to continue to abuse the tranny. I'm good with 11.3-11.5's at 119-120mph.

^^ all depends on the TCU/tune applied. That may not be the case. I doubt it's 30% more power. Off to watch the video though as I have no idea what it's about.

 

[TTQ B4U]

What I am saying is that the car with paddle shifters can shift at a higher power range than the other.

^^ the above all depends on how the vehicles transmission is tuned. Unless the car tends to short-shift in auto vs using manual modes, then there will be zero gain. Most cars shift identically regardless of the method used. I don't own a dodge like the one in the video but I've raced many at the track and know the owners. Most leave the car in Drive and let the transmission shift as my understanding is they don't shift any differently.

again, all depends on how the car is tuned and it will require an aftermarket tune to make anywhere near a noticeable difference and on a NA vehicle the difference is going to be minimal compared to a boosted car. Ask me how I know in both cases
