**** poor exhaust tone/sound

So you are saying a turbo engine has "instant torque response" compared to a N/A engine?

I know Ford used tiny turbos to fight the lag, but come on. Until the turbo spools, you have no boost. It doesn't spool instantly.

If you want to experience true instant torque response from idle to redline, you should drive a V8 with a positive displacement supercharger.

I've been saying all along that there's virtually no turbo lag with my Gen 2 and I honestly feel there was more lag/hesitation with my Gen 1 when mashing the gas to the floor and I thought it had something to do with the traction control as well. My Gen 1 was a whole different truck with the 5 Star tune and most if not all of the hesitation was gone after tuning it. I'm well aware of what turbo lag is because I had each yr of the Buick Grand National and those V6's had some serious lag to them and both of my wife's Mini Coopers had quite a bit of lag too.

While I prefer a PD blower for almost any application, I can say the sport mode for the ecoboost really wakes it up down low.
It really cuts down any lag to the point where it's feels like it's almost instant.

Been driving a loaner ecoboost f150, and a switch to sport mode really makes it a fun stop light to stop light truck.

Well that's not true with a PD blower. You still have to build boost.

Have you driven a vehicle equipped with a roots or twin screw supercharger? There's no such thing as building boost with that type of supercharger.

A PD blower is always "in boost". A bypass valve allows the compressed air to go from the discharge side of the blower back to the inlet side of the blower, effectively keeping the cylinders from seeing any boost. As soon as your foot drops, the bypass valve snaps shut and you get instant full boost. I guess you could say there's a lag from the bypass valve closing, but I bet you can't actually time it because it happens so quickly.

Well since I've not driven a Gen 2 Ecoboost- I'll take your word for it that's it's not a laggy setup. You guys are obviously knowledgeable enough to know what's what.

Haters will call it a Fiat. Reality is Ram is keeping the faith.

I'll be the first to sell the damn gen 2 and buy that beast...if they make it!

Nah...I don't know anything about them. I'm just weighing in without any firsthand knowledge!

The V put 725 to the rear end and the Vette, well it was salty but not my cup of tea. You cant tell that there is any lag but to say that there is no lag is not accurate. My point being that there is no such thing as no lag in a forced induction engine.

boy this thread got off topic. Ford knows they sound like shit, thats why they pipe in the sound. for you gen 1 owners here is an app so you can hear a gen 2 ;p https://play.google.com/store/apps/details?id=au.com.revheadz.revheadz&hl=en its for android, im sure there is an ios version as well

If you think what you experienced in a 2017 Raptor was boost lag...than you don't know the difference between boost lag and drive by throttle wire lag.

Oh good, you're finally learning something

this is what I'm talking about dodge is not going away from the V8 so looks like we go with what ford tells us we should like or we move on

I didn't realize ford offered a stock v8 supercharged engine. My bad.

Clearly you haven't looked at torque charts for the GEN 2 vs other stock trucks.

btw there is no such thing as (drive by wire lag) any "delay" is put there by design and can be programmed out. Turbo lag is real, but on todays turbos its minimal compared to 20 years ago...still annoying. Soon we will have the F1 hybrid turbos and then we can finally say goodbye to lag.

If it makes you feel better you can call it delay instead of lag.
But it's still the electronic throttle/drive by wire system lag/delay....and yes it can be programmed out with tuning. Another option quite a few people on this site are using is the Pedal Commander. > http://www.fordraptorforum.com/f261/pedal-commander-awesomeness-52321/
