i remember a tri-turbo supra(i didn't want to bring it up but thats what it was) being in an import mag a long time ago. doesn't mean its a good idea. but hey i want to see a twincharger on a G or Z too.

 

I would think a SC with a ST would be doable . Running the charge pipe from the turbo to the IC on the passenger side . The air intake for it would have to be ran on that side too

 

i think ud need a huge cooling system. this sounds like something that would over heat pretty fast.

You could use the stillen with the turbonetics or any twin turbo setup since the supercharger takes up the space for the manifold

 

The Twincharged MINI is perfect example.

Your right, the setup is rediculously expensive, and it probably won't get done by anyone with common sense. But if it's done right, you WILL be a very scary on the road.

The Single Turbo + Supercharger is a better option though, and it can be done without blowing that much money. You'll want to run a T88+ sized turbocharger for maximum benefit. You *MUST* also run a twin-screw kind of supercharger, as roots is inefficient and the centrifrugal is completely useless.

If you access to 20 PSI at 3-4k RPM I don't think anybody would complain. Traction will be an issue of course.

 

Sounds cool. Now somebody with a boat load of money needs to do this with their G or Z.

 

Why won't this thread die??

 

its a good idea...and it can be done with alot of money...dont discourage people who like this idea cause...u know for damn sure if u saw a twincharged G/Z in person...you'd sweat its nuts lol...post pics of that evo if u have them tho...

 

the other expensive part of the operation is probably gonna be building the engine to handle that sort of stress, and of course traction.

 

+1 on the idea. Its definitely possible, just need a VERY deep pocket and a very good cooling system. This been done many times. Lancia Delta rally car back in the group B hey day had a twincharger, made enormous power. First gen Toyota MR2 with supercharger, HKS made a twincharger kit for it.

Hey, if Top Secret can shove a V8 with 2 turbos under the hood of the G, who's to say a twinchargered G is out of reach.

Here is a few the Delta linky for those who don't know;

BTW, if you ever go through with this, post some picks and the dyno chart.

 

I saw a G in japan with Twin Charger setup. it was in option magazine or skyline

 

I don't necessarily believe that it would require a ton of money to accomplish.
Less or equal amount as a TT setup.

"VW has their Euro-market VW Golf GT that was equipped with the manufacturer's new 1.4L turbo- and supercharged Twincharger (or TSI) engine. So, how does it perform? Much like one would expect from a powerplant that manages to make 121 HP/L and also provides nearly 85% of its peak torque at 1250 RPM"

The Gold GT is not that expensive of a car, and they are getting 121hp/L out of it.

Sounds promising.

 

First of all, I'm glad that there are people on this forum that can actually comprehend and expand their way of thinking for just a brief moment. This isn't a conventional setup, nor is it an original one. It's purely just a rare one.

Traction will definitely be an issue as the whole purpose of the twincharger is to have horsepower come in as FAST as possible. On a built G35 with the appropriate modifications, you can definitely overwhelm the tires without a problem from a decent roll. AWD is definitely a good option, otherwise, a stiff rear suspension, wide sticky slick tires will definitely help.

Nissan has built its own Twincharged car, it's called the Nissan March. It's twincharged, on a *VERY* simple engine. I believe the engine only pushes out 130 HP, but the power comes on very quick and has plenty of torque for a 4 cylinder. On a much more advanced engine with variable valve timing, 4 valves per cylinder, etc etc the power potential is simply much greater.

Lancia Delta S4 is a classic twincharged car. It's design is a bit antiquated as I believe its supercharger pushes its turbocharger. This design is flawed right off the bat simply because the turbocharger can spin much faster than any supercharger, and if the supercharger is the main intake, it's going to be a hindrance on the turbo.

Now, if you switch that around, not a problem. The supercharger will spool, and as it reaches its limits, voila, the turbocharger is behind it and is feeding it boost, thus making the supercharger useful.

 

most people here would not be using slicks as their g's are daily drivers. the problem lies in the weight of our cars. all the above cars mentioned are extremely light a$$ cars with tiny 4 cylinder engines. no one is saying it cant be done, its just extremely unpractical until someone can figure out the traction issues.

aside from that, I think the setup would sound so sweet!!! a supercharger whine with a turbo spool simultaneously. its gotta sound like starting a small jet.
