Turbo lag
I have searched and read, read and searched and all I get is confused. I am new to forced induction and quite frankly am some what intimidated by some of the abbreviations. I love my little 4 banger and don't have any plans for any major upgrades, I love everything about this car except the turbo lag. So two questions I have been trying to answer are as follows.
Is there any one thing that does better at reducing lag than the other (i.e. CAI, tune, down pipe, etc). When pulling from a dead stop does it harm anything by holding the brake and increasing RPM before launch (2500, no tire spin), this seems to get me out of the hole quicker. Thanks in advance.........please be gentle. |

1) Typically, a down pipe has the largest effect on turbo response. However, combining that with an intake and a tune will increase that effect even further for each component added.
2) I assume you have the 8-speed automatic. If so, then that won't do really any harm if you do it for a short duration. There is a term for it, 'brake boosting'; kinda like a pseudo launch control.

I'm wondering if that lag you are referring to is not lag, but throttle controlled by the pcm(cars computer). For everyday driving I think it has more to do with the pcm's control. Either way, downpipe and or tune is your go to fix.

When you hold the brake and the gas down, you're building boost, which will always work to a turbo car's advantage rather than flat footing the throttle. So when specifically do you think you're incurring lag? With a good answer to that question, we can probably get you pointed in the right direction. |

Decided to wait a while before responding to get a better description of what I am trying ti identify. Running around 40mph want to increase speed a little aggressively, give it half throttle.......wait.......then she takes off. Just a basic scenario of what I'm feeling and since this is my first turbo thought it was turbo lag. After reading thru other posts maybe I am experiencing throttle lag instead. Either way I would like it to be more responsive with out having to go WOT.

So is this why I see a lot of people going with aftermarket throttle controllers, and some may "think" it helps with turbo lag?

Sounds to me like you understand the difference between turbo lag and boost threshold. Because you are describing a roll on scenario and not a from 0 scenario. A from 0 (mph/wheelspeed/engine RPM/whatever) situation has more to do with boost threshold than turbo lag.
So considering that this is a conversation about turbo lag, any flow mod (intake exhaust) has the potential to reduce the amount of time it takes the turbo to reach boost when you are at an RPM > the boost threshold. IMHO throttle controllers are an interesting solution to this as well. *Note to the throttle controller haters, please read this carefully before replying* The throttle control will often be sending a signal > the actual pedal position. This means that the engine will likely be able to make boost sooner. Additionally the predictive ramping of a throttle controller may reduce (however minimally) the amount of time it takes to reach full boost. Subjectively my car felt like it had less turbo lag after installing a throttle controller on my car (because the throttle map changed). For the manual cars I really enjoy the no lift shift feature. It dramatically reduces the lag feeling during WOT up-shifts. Hope my rant helped a little. Thanks for joining the community man0steel

It's because the gearing and the power delivery. If you want power, downshift until your rooms are around 2.5-3k then hit the gas . You will experience and turbo thrust like never before. If you do it at a good speed and get the gearing right. It's fast as ****

2017 Camaro 2.0t - Not as good as the 2.3t Mustang ?
What are your thoughts. My major point is that the Camaro is light weight and balanced better. Mustang is priced better.

I have notices that to what the thread is about and on the fence about the down pipes and CAI. I did run a Roush Mustang this weekend and was beat but not by much, he freaked out when told him I only had a 4 cylinder in the Camaro and just factory with no mods.
