Is possible to make a project with a Twin-charged to a built renesis? A supercharge + turbocharge. I see many others engine have a new setup of twin-charged and get a impressive results and wanna see if is possilbe in a built renesis.

 

why?

 

supercharge for the low end and turbocharge for the upper.

vw made a very gas efficient golf using this method with a 1.3l 4cyl engine.

it hasnt been done with an rx8 before. but anything is possible with enough money.

 

we have been over this....search

 

If you properly size a turbo you can have both with one

 

i dunno. the vw engis did it for gas mileage, so im sure there was a reason. they werent going for max hp.

 

But there is a more reason that why is using a twin charged, not just for power on the low end and turbo for the upper. Using any size of turbo, I think is not same just turbocharged vs supercharged + turbocharged. I saw a article last month in the Turbo Magazine and is a Scion Tc with a twin charged setup and they made a comparassion between the power they got in the turbo kit and them the turbo kit + supercharge. The Scion Tc with the turbo kit only got 280whp aprox. (I don't remember exactly) and them they install the supercharge and them the result is 390whp with the same boost of the turbo kit setup.

What I plan to do after make many research is a Turbo Kit + Petit supercharge and use the Scott Interceptor-X for ems. I plan to use the turbo kit with a GT35R with A/R 1.01 because I have right now the SFR kit with the T3/T4 turbonetics 60-1 and is not flow enough air. My engine will be built by Scott and what Scott saids is going to be stronger than stock one and going to hold a little more of boost.

 

What is the different between the twin charge and the RX7 sequential twin turbo (I mean the theory) ?

 

twin turbo is 2 turbos. twin charge is a supercharger and a turbo

 

If you are already talking to Scott, why are you asking us? He is one of The Premiers of this forum.

 

If your planning on actually doing this .. you bought the wrong car to do it to.

Oh, come on! This has been done on a Mini Cooper S already.

 

I would rather twin turbo...

 

And there is an Easter Bunny

 

I missed that second paragraph. Thanks, Rich.

 

lol....what i plan do is make large reel horsepower fo wong wife weriability.

Strangely enough my group are working on this exact same concept in Auckland New Zealand for aero renesis applications. It was used to great success in WW2 fighter engines and there are a couple of standard cars such as the Golf and one Nissan that use the same concept with a magnetic clutch.

In an aero application it has great benefits with altitude.

We are working with the engineering Department of the Auckland University of Technology on this where I am a Professor.

anyone is most welcome to email me to share ideas

Remember the knockers told Edison electric power and the lightbulb was impossible - once people thought the earth was flat - do not listen to all the "arm chair" experts here - just try it! People said the atom could not be split - a famous NZer Rutherford showed otherwise.

You folk from the USA need a lesson in good Kiwi inventiveness

Perhaps the Professor needs a lesson in researching our forum before issuing admonishments. We have plenty of people from all around the world whom we admire and respect.

 

It's not that the idea doesn't work, or couldn't work, but that it isn't a very efficient (cost wise) means of achieving power. Why spend three times as much and four times the headaches for just a fraction (if even) more power? Plus, you're adding twice the complication to the problem than need be.

The point being he could achieve his goals with a single, properly sized turbocharger, but I think he wants bragging right more than anything.

 

ok,

i will bite..

name the turbo supercharged aircraft from ww11. and name the one designed in nz..


btw, i do really hope the project goes well.. as you have a source of funding..

beers

 

Yes us kiwis are pretty good at it but if you have a look around you will find there are plenty of inventive people on this site ....

OH - and even if you did come up with something that worked I doubt there would be many takers prepared to pay the cost and suffer the complexity ..... that is if you were talking about cars .

 

Uh-uh... so it's the same engine at the same psi, but power output is multiplied by 1.5, right? What's heavier, a ton of bricks or a ton of feathers?

You remind me of a friend who had BIG PLANS of "adding 3 VTECs" to his Honda. His exact words where "... you've got one that hits you BANG at 3500rpm, then another one at 5500rpm WHAM and them WHAM-BANG third VTEC at 7000rpm! So you get over 500hp without even changing the intake, the exhaust or chipping it! SERIOUSLY I SWEAR MAN". Guess what, that project never got farther than a fart-can.

I don't want to be rude, it's just that... it all doesn't sound very serious. Think about it. Like Chickenwafer said "you're adding twice the complication to the problem than need be."

 

suggest you re-read it then because if you think that 110more hp at the same boost is even a possibility you have some serious learning to do .

 

Hahaha, that would bring new meaning to "VTEC kickin' in, yo!"

 

VTEC: All the lag, none of the turbo.

It's like waiting for bad sechs.



Okay, seriously. Along with sequential twin turbos, twin-charging was something that kinda made sense before turbos were good, when there weren't really turbos with the broad performance range that allowed you to have good low-end response and top-end power. The car manufacturers got good enough at control systems to make sequential turbos kinda work a couple of years before Garrett got good enough at turbos to make the sequential thing totally unnecessary. IMHO, twin-charging peaked with the HKS kit for the MR2 SC.
