OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

Ouch. Capslock set to kill, captain.

Still in for the boosted third gen when it exists at some point in the future. Oh, and in for the

 

I like to imagine he held shift while angerly typing all of that.

 

A single turbo will be laggy due to doing all the work. Twins that are smaller can make the Same boost with more air flow do to less resistance needed to spin them up. In pure performance most run singles for simplicity reasons, but a twin setup with same HP goal will actually come on faster than a single setup would. It's why Ford EcoBoost v6 has twins instead of a single.

 

Assuming you are talking about twin parallel, I don't think this is correct. Can you site a source on this information? Im not an expert so I may be wrong.

 

Depends on the turbo, some single turbos are designed to spool really fast. Besides, Mat already said there’s simply not enough room for twins, the position of a second turbo would be hanging so low that it could be easily damaged by road debris or off-roading

 

Twins are the same turbo, its identical turbos are true actual twins. Compounds are another form of turbocharging completely, I have a set in my garage for a 4BT that I built the piping etc for myself. And I don't have a source to copy and bring in right now. But think of it from a physics and a science form, turbos can be bolted directly to the manifold, then down pipe to a y pipe an out. A single on a v6 you need completely new pipes, and since turbo is down stream VS right off the head does add a minuscule amount of lag.

 

I've read the whole thread and I'm sure I've forgotten some stuff along the way Haha. But yeah, if I recall he mentioned 3 turbo choices, small medium and a large, 13T? Was the baby version I believe which I think was a 48MM compressor wheel, that should spool really well hopefully down low, then you'll suffer on the tip end, gotta love the limits of turbocharging lol.

 

Doesn't the new supra make near peak torque at 1600 rpm or something? I think turbo lag is a thing of the past.

 

Haven't actually checked into the new supra, I love the older one though, and I'm not arguing so dont anybody think I'm doing that, just stating what I've seen. What I've seen about Matt, he seems to be really focused on the term *area under the curve* which is amazing, make the truck a real beast.

 

The choice between twins and singles comes down to packaging and nothing more.

Two small twins have just as much as inertial weight at a slightly larger single.

It takes two 47mm comp wheels to equal one 62mm. It's only 15mm larger. I know I've grossly over simplified this but I just wanted to point it.

Turbo performance is down to matching the turbo/turbos to your engine, not the amount of turbos involved.

 

That isn't exactly accurate either though, diesels pushing 2500HP use triples, IF a single could do the same, it would need to be like 250MM compressor wheel to match the airflow a triple setup could do, so saying the amount doesn't matter is a slightly inaccurate statement Kyler.

Nope. 98mm will do it.

Also, compound turbos are a different beast all together. They do provide the spool up of a small turbo with the power of the larger turbo.

Unfortunately, Compounds on a gasoline engine are a huge pain to control.

 

Okay, so I think I'll believe the top 20 diesel shops in the US who run triples. If a single would do the job, they'd run singles to save weight dont you think? So yeah, I personally OWN a compound diesel engine and can say a compound setup comes on way faster then a single turbo, do you have personal knowledge on this? That picture is off my engine.

 

Compounds on a gas engine would require fancy and careful control of the waste gates yes.

 

I tried everything to make twins fit. They won't unless mounted under the truck which I do not like the idea of.

 

The floors aren't needed are they? Rofl. If I can ask how is the single mounted right now? Near the transmission some place?

 

I'm not trying to say that compounds don't work great for a diesel drag or towing application.

I'm saying, on a gasoline engine, the idea that a single will be have more lag than a twin setup is just not correct. If they are both setup properly.

 

If their setup properly yes, most seem to get stuck on the *peak* HP number and forget the concept of drivability, OVtune is wanting drivability though which I praise that.

This is on an rb, so not an exact comparison, but something to watch in regards to single vs twins...

 

The twins were also stock units if I recall that video and this is also on a inline 6 were a single makes more sense, I'm referring to V engines not inline.
