Supercharged Turbo Vq35de?

I highly doubt they had both on aeroplanes. I can assure you they had one or the other cause I'm a complete plane nut

Now don't tell me that turbo's make power for free cause they use wasted exhaust gas, and superchargers use lots of power from the crank cause I'll prove you wrong and you'll eat your words, if your honest.
Read the following with a open mind and then lets dig into the meat of the turbo vs supercharger.
If you want well do this in 2 parts, the 2nd part being to remove the myth that a low compression turbo'd engine makes more power than a high compression engine, and this I promise you when were done with this subject you'll be able to speak with authorty with facts. Fair enough?

I tend to agree with you. Both turbo's and superchargers have their strong points. A turbo in the end will make more HP than a supercharger will. Turbo's are more efficient that supercharges also. You get better MPG with a turbo becuase it isn't always spooled, especially cruising down the highway.

Those guys on superchargeronline don't know squat about turbo's either. They say the wastegate opens to limit the RPM of the turbo, that is not true. The wastegate opens to limit boost (they also say that, but say the RPM limiting twice).

They also say that you will get a surge when the wastegate opens, more BS. The surge you get is from the turbo spooling up, not anything to do with the wastegate.

Pretty much the rest of what they say is right, but they make it sound like a turbo is a niche market. Just look at the number of turbo'd stock vehicles compared to supercharged ones.

I also disagree with you saying that a low compression engine will not make more HP than a high compression engine. I would lke to hear your version first though

Let's keep this to an intellectual conversation, not a pissing match with name calling and such. I am very open to other ideas and I have a lot of experience with turbo's.

The wastegate does limit turbine rpm.The wastegate opens lets exhaust escape to the downpipe as opposed to entering the turbo. Less Exhaust = Less Turbine RPM = Less Boost.

You want to spend $3k to make up for 2000rpms? Eh, not worth it. Especially tuning each of them and properly setting them up.

Wow I think its a slammin idea man.. GO ahead, Supercharge and Turbo and your right the power from the supercharger will help in the low end. My question is tho how to stop that infomous parasitic drag... How bout run the Supercharger off an electric motor instead of off the crankshaft.. hmmm.. possible. Or instead of that try running the Turbo in to the intercooler and then through a twinscrew supercharger into the intake plenum. using the intercooler for just the turbo compressed air will allow the tempetures to drop enough for the supercharger, you can even use a water, methanol mix injected right before the intake plenum to cool the intake air cuz we all know that cooler air makes more power. All in all the slight loss of power from parasitic drag will be so minimal that it will be unoticable. anyway good luck on that
