Actually, I think using the turbo(s) to feed the supercharger is probably more common.

 

What about the difference in compression ratios? Since SC's come on quick and turbo's spool is it safe to say that this resembles the power a SC'd car with NOS would make?

 

I don't think differences between the supercharger's and turbo's compression ratios will present a problem, so long as the supercharger housing can hold up to the amount of boost being generated.

 

few things

1- Go 4 it bc it would be awesome if i did indeed work
2- if our cars stock are efficient to 8-9psi, is it bad a SC pushing 8psi and a turbo pushing 9psi Does that make it 17psi
3- +1 on the it would be cheaper 2 go built big turbo. SC+STS= Maxed out credit cards

 

Go for it! It would be unique at very least, and if you already have half of the setup, not nearly as expensive as people are suggesting. Probably fun as hell to drive too.

Just make sure you get a good tune.

 

if he run more than 10 psi on wastgate side, the supercharger will be at risk,

and out of efficiency, the engine will run higher power+ more torque

and ur SC will Die.


correct me if im wrong guys.

 

If you're just paying someone to do it, make sure they exactly know what they're doing. If you're doing it yourself.. don't, until you understand exactly how to read a turbo compressor map. Twin-charging is way more complicated than just "stick supercharger kit A and turbocharger kit B on the same engine." Assuming you use a 8psi pulley on the supercharger, and 8psi on the turbo outlet pressure, you're gonna be pushing >20 psi manifold pressure into the engine. If you use any regular turbo kit-sized turbo compressor, you're gonna choke the compressor with ease. You have to match pressure ratios and flow rates of the turbocharger to the supercharger drive ratio, unless you use a (large) external bypass valve on the supercharger. And then you have to add active control to the bypass valve. That's just to start. It gets seriously complicated, and very expensive.

Twin charging is really just gives you a neato factor to the car, nothing else. In all likelihood you will spend almost twice as much as a basic twin turbo kit, and end up being not be as fast (or reliable). Having said all that, it looks pretty cool on show cars... but I would never go and do that on a non show-only car.

 

There's no risk to the SC, its just a displacement pump really.. but the compounded air flow/boost ratio can make for a ridiculous amount of boost, nuking your engine in a hurry.

 

There really should be very little fab work. You might need to extend the last charge pipe with the MAF housing to get it to line up to the blower. And you would need to find a way to mount both intercoolers by chopping the front brace and extending the brackets on the STS intercooler.

 

hi,new here. someone in South Africa has done this. check out nissanownersclub.co.za. almost look like a sts turbo setup with a vortech supercharger. he will be finished in a few weeks.

 

Actually it is the other way around.

Generally this is done with a positive displacement blower such as the Stillen roots style blower. The reason is that a positive displacement blower has an internal compression unlike a centrifigul supercharger.

Imagine a roots blower as a small engine. If the turbo blows into the supercharger you will effectively raise the internal compression of the blower which will be 'exhausted" into the engine. It's kinda like "boosting a large engine with the exhaust flow of a small boosted engine".

Even easier is the idea of series pumps in fuel systems using one pump to feed the next pump and allow for a higher net pressure than either pump could do on its own.
