Twin Turbo vs. Single Turbo V6: A Dissertation

Vince@R/T · 01-21-2012, 11:33 PM

This thread is cracks me up...everything stated is pretty common knowledge if you are in the industry. Twin turbos spool faster and seem like a better choice for street use....Singles are more efficent and have a higher ceiling for growth then smaller twins....no ****.

I think the issue is the definition of street use. What if a guy wants a bigger single for a lil delayed TQ and wants it up higher in the RPM range and more room for growth without having to practically drop the motor out to switch up turbos. Maybe the guy for steet use doesnt want instant TQ and boost blowing off the tires everytime he is half throttle...

So the other guys wants twins and quicker spool so he feels it in the chest and the car feels faster. Maybe he thinks twins on his 370z is the same as buying a GTR....who knows?

This is America, if a company makes a good product it will sell(whether it has 1 or 2 turbos). If it isnt a good product...It wont. Obviously both have there pros and cons. At the end of the day I bet it has more to do with the companies customer service, how quality of a product they sell is, and how well they stand behind their product then it does with a couple 100 rpms of spool...

It's nothing more than a sells pitch for who has the best turbo for the price. At the same time number don't lie and I think I'll stick with my single rear mounted turbo....until they finish the twin version.

ST= Single turbo (location not specified, but I know #2 on the list is a top mount GT42R)

STS= Squires Turbo Systems (a company, making rear mount turbo kits)

So I don't know how you got STS out of that.

If that is all you got from the list then...

Yeah understand and know what STS is and stands for....have one.

I was just curious about the same thing.

The chart is also from the vq35 motors n not the 37. 2 different motors. On my 35 I had a single turbo build, gt35r powerlab which kicked arse everywhere I went n never gave my any problems. I love single turbo's n the way they kick in n the torque. But the vq37 motor is not the same as the 35 so it's safe to say that until more r&d is done to make sure single turbo kits r a reliable option I think TT is the way to go on these motors. But I also disagree with this thread to begin with in the first place.
It should have CLEARLY been titled "GTM TT kits is the best n single turbo sucks arse so buy our kits".
Now if GTM offered single turbo kits that would be a different story but since u guys only have TT kits kinda makes u guys a little biased eh? Just sayin, nuttin personal.

I agree, especially with the second part.

The list is from the VQ35 equiped cars, but the original poster says that this "theory" applies to all V6's because of the exhaust pulses. That is why I thought the list is relevant.

I will probably not be using mine for the track. This is my DD for me and the fact that I won't be going through tires as often is always a plus. I have seen up to 38mpg,drove for 2 1/2 hrs and averaged 35mpg, when cruizing at 80mph on my single.

The thread does have done good info about heat and enthalpy but I def agree

U do know that if you change injectors the mpg readings from the stock trip computer become useless. Right?

So when they remap the car that isn't part of it. If not I know now.

Infomercial or not, I learned a great deal in here. Props. To all.

This is moving pretty well for a single turbo.
