It'd be funny to hear a guy mouth off that setup. I've got an supercharged, turbocharged, ITB miata NOW WTF IS UP???
Now I get it. You are a 15yo kid in high school dreaming about fast cars and just want to discuss completely "money is no option" ridiculous unpractical setups. In that case why stop at miata? Hell, go big or go home: why not stuff a v12 in there, twin supercharge it, quadruple turbocharge it, and throw "2 big ones" in the trunk? Sounds pretty ******* ridiculous huh? "Id like somebody to mouth off to that setup"

Back in the real world though, people like us drive miata's. They are a cheap/affordable fun little car and the best part of making them quicker/faster is that it costs little and you get alot of fun for your dollar. Thats it. Sure some go all out and nuts with crazy setups, but most of those people are either sponsored racers, or power junkies with lots of money and time on their hands, and love to custom fab parts to their cars.
Does twincharging work? sure......Is it badass? sure on some level. But its been proven like 100000 times that its not practical, because at the end of the day a guy with a big turbo/built engine or a v8 will still be right next to you down the track and your "instant throttle response" wont help you for ****. That is beside the fact that you can only hook so much power to the ground, and the chassis will only take so much torque before you have to pretty much re-engineer the whole car to handle more.

in summary: your topic fails

good day to you sir

Actaully I said itd be funny to hear someone mouth it off, because its so rediculous to have that many different systems combined into one. I'm not 15 I'm 24, I'm also an aerospace engineer who does this stuff in his spare time. I'm the only vendor of adaptronic E.C.U's in north america, and I engineer all my own components. I wasn't really contemplating on a hearing of the twincharged setups or even debating them. I just wanted to see the other twin charged setups... I don't quite know why all this is so hostile. Jeeze I just wanted to see who had them and what their plots looked like.

lol...I dont know, but you came off kinda hostile, so I returned the favor.
well I dont know of any twincharged miata setups, but at least now you know my thoughts on it

I don't know...Hmmmmm If you put cinnimon in it, and make it steamy and rich. Apple cider is good.



Ps: Isn't this where the thread supposed to stray into girly pictures. Enjoy!

I think twincharging is a good concept if you can control and smooth out the transition between SC and turbo. We may see more of this as engines get smaller and smaller.

I highly doubt it....and engines are not getting smaller...look at all the 6.1L srt8's driving around

Well, someone is at least doing the V12 part.http://forum.miata.net/vb/showthread...highlight=v-12

Maybe in your gated suburban community and archaic Chrysler, but not the rest of the world.

Is the 335i sequentially turbocharged? I thought they were parallel turbos.

The 335i turbo system is not a sequential system. Each turbo is supplied by 3 cylinders.

whatever, either way.... just chose the right sized turbos....


here... I'm thinking of the 3.0L diesel:




1. At low engine speeds the intake air flows through the large turbocharger and is compressed in the smaller turbocharger. This supplies substantial amounts of air to the power unit, starting without any appreciable delay at idle speed. The 3.0 litre inline six-cylinder diesel develops 530 Nm of torque at as early as 1,500 rpm.

2. With increasing engine speed, the larger turbocharger becomes more important - initially as a pre-compressor. The intake air is additionally highly compressed inside the small turbocharger, the engine reaching its maximum torque of 560 Nm at 2,000 rpm. By means of a turbine control valve, the flow of exhaust air is variably distributed to both turbochargers, regulating their interaction.

3. At high engine speeds work is done primarily by the large turbocharger, the power unit reaching a maximum output of 200 kW/272 bhp at 4,400 rpm.
