Twincharged..
 

Any twincharged miata's around?

this begs the question: WHY?
not only would it cost a shitload of money, but with a small turbo like the t25 and the miata being as light as it is, lag is pretty much minimal.

Well the main purpose of a twin charged setup isn't to give you that worthless extra grunt at 1500 R.P.M. It’s really to make sure you're 1.8L engine can spool a T-67 by 4000 R.P.M. Think about it. Mustangs make about 200 WHP stock. With a decent supercharger on the Miata you can do the same, so that produces about the same airflow and same spool-ability as a mustang. I guess you can do it with a nitrous shot too, but the car is complete crap when it’s not laughing. Throttle response is also incredible with a system like this, and I guess if your grandma that extra at 1500 can't hurt.

By twin charge I was speaking of more the bypass supercharger when turbo comes online and the supercharger is electrically clutched to disengage type. So it wouldn't be compressor to compressor feeding all the time just when the pressure upstream of the supercharger was below a certain amount. Kind of like VTEC for Forced induction.

oh boy....!!

I get what you're saying, but still dont see the point of something like that. main reason is that its not that pracical, and would cost a shitload of money. Hell, you could just throw a ls1 in a miata, it would cost about the same, and have the low end grunt and topend pull........and more than enough power/torque to keep you from falling asleep at the wheel....or you could build up the 4 banger and throw a good turbo on there and still have good power with decent spool...any which way you put it, a twincharged setup is expensive, complicated, and generally not worthwhile...simply put: stupid


now if you are stating this simply because you're bored and want to talk about something "different" no matter how bizzare/pointless, thats a whole other topic. in that case id tell you that this thread is stupid and politely leave :)

Opinions are just like a__holes everyones got one. :giggle:

The reason I am never in favor of V8's is because I generally hate V8's. Something about the little engine that could that just makes me love 4 cylinders. This is a way to genuinely amplify the power of a 4 cylinder by using huge a/r's or in general huge turbo's and greatly increase output, recoverability, driveability, and put yourself at a serious weight advantage and packaging simplicity over a V8. Really the most expensive part is the standalone, once you get that, the rest is just tinkertime, because you're not going to find a company stupid enough to try to make one. So cost isn't really an issue, in setting out on a project like this, I would assume you'd know how to design one, build it and install it.

I think nothing compares to the sound of a healthy V-8. I actually hate 4 cylinders, cause most 4 banged cars are wrong wheel drive, and people put gay shit on them like air intakes and fart cans and then think they're fast. The reason is drive a miata is cause it's light, cheap, and there are a thousand different things you can do to them. The 4 cylinder in my car can be upgraded in many ways to push my little go cart of a car to unheard of 1/4 times, meaning, I could spank V-8 cars like it's a sick joke. I don't care what anybody argues, but the only reason you can make a miata fast with the 4 cylinder in it, is cause of weight. I like your thinking though, cause I too am the kind of person that is into doing something different than anybody else. I must say, there comes a time in that where you have to just say, "how about I forget about being creative and just do something similar, but not." Basically what I am saying is, get your standalone, build a block, put a T3/T4 hybrid on there, and run 350whp. The lag time shouldn't be that much of a set back. You have to know what you want the car to do, and what the car is designed for. Miata engines were designed to make peak power at like 6400 RPM?? So don't try to change the design and make peak HP at 3000. Let it spool and your appetite for power will be fed.

It's been done... Coldside supercharger with turbo.
Seen the video too, spool was amazing fast but difficult to control the boost level.

Thats what I was looking for. I wasn't really looking to argue it. I just wanted to see other peoples kits. That torque curve is amazingly thick, and Its gaurunteed the 2-3 shift benifits alot if it doesn't go sideways.

So basically, the idea is to spool a large turbo with the Supercharger, if I'm reading this right. ...but if better spool on a big turbo is all you're after, nitrous can do that (they sell kits specifically made for spooling a turbo and then stopping) and once the turbo comes online, you won't have the restriction the dead super would impose. (or the complexity of bypassing it)

why don't you stop posting here so I don't have to rape your face?

Every blown car I've ever driven had shitty throttle response. If a turbo car fell on its face like a blown car did off idle, you'd call it lag, but since its a blown car you call it "awesome throttle response."

Well alot of that has got to do with how they design it. You're still limited by the speed of sound on throttle tip in, but it should gain in revs alot faster once air gets to the port. I guess the best setup would be ITB's with a supercharger and a turbocharger. :giggle: Good throttle crack response, constant boost available so rocketing revs, and a turbo to take over in top end. It'd be funny to hear a guy mouth off that setup. I've got an supercharged, turbocharged, ITB miata NOW WTF IS UP??? :bowrofl:

I have a V8 swapped Miata with a roots blower, ITBs, two turbos under the trunk, a 300-shot of NOS, and Darude's "Sandstorm" on repeat in the CD player.

so combine them all and stfu

here is the link for tt miatas

Who pissed in your lemonade? :bang:

Its just conversation. Its not very often you find a forum with people bright enough to talk about it.

I never understood the TT miata's there is only so much exhaust gas energy you can get ahold of.

And you don't pay very much attention around here do you? If you did that comment shouldn't have suprised you at all.

I'm a newb I've got 21 posts ;)

Just put a turbo on it.

(this is coming from a SC nazi)

Seriously. If you've never FI'd a car before, just turbo it. You have too much to learn to try to start big. Here I am never turbo'd a car before and I'm trying to put a pair of twin screws on a miata. Shit is hard as hell to fit and it's waaaaaay waaaaay WAAAAY too much work. I didn't think the worst case scenario would be this bad. Sure it will be neat when it's done, but if I didn't have all this time, research, work, calculations, and talk in the SC project, I'd be ordering a turbo and manifold.
