Turbo Lag

[Rho5280]

For those who have taken order. Is the turbo lag from stop obvious? If so how bad? Had Land Rover once that almost killed me it was so bad from stop.

I don’t notice it near as much as my 22 Raptor. So much better.

That’s refreshing. Literally the single item that I hate the most with anything turbo charged.

My 22' Raptor doesn't have start/stop? How were you so lucky to get it?

Strange, but it doesn’t feel like turbo lag because you can’t really hear the turbos spooling up…it more a change in exhaust tone…it becomes a bit gravely if you lug it under boost, like you were driving it as a diesel.

The engine is pretty soft below 2200-2300 RPM, at which point, Ram says 90% of peak torque becomes available. Below that, the engine is obviously building boost.

Ram seems to have done a good job with gearing & torque converter slip, because if you hit the gas quite hard from stop, it jumps to 2200-2300 RPM & pulls pretty hard with no obvious turbo lag. You might feel it during shifts if you lift the throttle a bit.

To be honest, until my 1st oil change is complete, I’ll not really hammering on it. So my opinion may change.

I didnt notice any turbo lag on the RHO I drove, felt much more responsive then the Ecoboost Raptors I have owned, and pulled much harder at higher RPM.

Think you are talking about turbo sound not lag. Typical turbo lag is from stop, you begin to accelerate and it lags prior to actually accelerating. Can be a huge problem when trying to step on it to merge into bad traffic and the vehicle pauses before actually moving.

I understand. I got my driver’s license in the 80’s, when turbo lag was measured in minutes (I exaggerate for effect, but it was bad).

I mention the sound because many people hear the turbos spooling spool up & the accompanying lag in power delivery, which is the telltale of turbo lag in many boosted engines.

Since the turbos in this engine are relatively muffled, you can only go by the “feel”. Which as I mentioned, the engine “feels” soft under 2200-2300 RPM. But, that can be minimized with hard throttle off the line due to gearing & torque converter slip.

An example of how Not to imolement twin turbos is the Tundra. Had a 23’ and the off the line lag was rediculous. My X5 has more power and zero turbo lag.
That and the crap quality in fit an finish made me dump it after 11 months.

Interesting.

My X5 M50i had quite a bit of lag. At least that was my perception. My wife’s prior TT was an AMG design and that seemed to have ZERO turbo lag.

Luv what Porsche is doing with the new 100% stoich turbo flat 6 in the latest 911GTS, but it’s complicated and $$$! It’s what happens when government regs meet engineers who won’t compromise.

Anyone notice any throttle pedal lag on these trucks?

The diesel are notorious for it and a pedal commander is pretty much a necessity.

I think the pedal-lag is actually what a lot of people actually perceive as turbo-lag. It's terrible in my wife's Macan (pedal commander made it better) and I have noticed it on the RHO as well, just not to that extent

That's a bummer. Ram/Stellantis is notorious for baking this pedal lag into the factory tuning. My diesel truck is most certainly NOT 1:1 pedal application to throttle blade position-- wish it was.

I don't get it... maybe to save the trans? IDK.

Turbo lag can be exciting, just gotta flip your perspective and embrace the g's. But yeah, twin turbos drastically cut down on the fun turbo lag. In cars, I far prefer a large single turbine and trying to tame the lag beast.
