Twin Turbo vs. Single Turbo V6: A Dissertation

Cell

There are other cars out there that have over heating oil issues when being pushed too. It is just that our cars come with a gauge that shows the temp. If we never had the gauge people wouldn't even think about it till they put a gauge in. This is why we have the option to add oil coolers.

lolwat?


if you have no gauge and limp mode, you'll know because of limp mode

if you have no gauge and no limp mode, you'll know because people would be blowing their engines at the track.

Yes we will know because of limp mode and people blowing up their engines at the track, but how many people actually goes to the track? I've heard stories of other cars going into limp mode and having engine failure because of high oil temps. Our cars are not the only ones with that problem. That's what I was trying to point out.

The oil temp issue is blown way out of hand in our community because we have a gauge. Don't misunderstand me though, it is still a problem especially for track use.

I never suggested that. I was talking general principles of engine function, and I think you missed that whole point. If you can't control the heat (e.g. 370Z in some conditions), it's a problem. If you can, the more the merrier. Pressure created through combustion is proportional to temperature increase during combustion. It's very simple.

Has anyone who is saying that a twin is superior to a single ever actually seen the STS single setup? As I said early if I can keep my turbo temp down cooler but still produce 50hp less and if anyone has seen a how hot these turbos can get. That can't be good on them.

This discussion (that has taken place after Sam/Mike gave the onslaught of information) looks to be limited to specific platforms, since the Z and STi were the only examples discussed (in the origional post). I am not trying to derail this thread or start any mayhem either.

Does it really matter? Different strokes for different folks. I think options and competition are good for everyone. Until these two different kits line-up at the track, it's all academic.

Competition is good. TT isnt for everyone neither is Single turbo setup or even supercharger. Do what makes you happy. Having facts and numbers also help. Numbers dont lie.

What do you mean controlling heat? How are we gonna controll heat when we are beating On the car? Heat is gonna come no matter what having 2 turbos under the hood is not gonna help. I understand the combustion thing but our cars are already at the threshold NA why would we want to throw more heat at It?

Kingbaby

that's why that single setup that S&R did is very attractive...to ease the heat part for the 370Z guys you could cut vents in the hood over the turbo like the supra guys. Or a nostril like the 350Z guys.

525whp at 9psi has got me pricing out parts...

Where is the OP at?

Well STs got there car to make 480 in 7 psi seems pretty good to me and the turbo is at the back of the car,

Nixlimited

Notwithstanding that you continue to completely miss the point (i.e. that generally speaking, engines work because of heat production)--controlling heat, e.g. dissipating it with the cooling system. For example, the cooling system can be upgraded to dissipate more heat so that the car can take more "beating." Beyond that I really don't understand what your confusion is.

Yea I missed the general part .. My bad

Nismo370

11k twin turbo miles and I've never went into limp mode, and I don't baby her either.
