Twin Charged Setup
 

I have heard a rumor that GTM has a Twin charged setup for the Z coming up after their supercharger kit. Has anyone else heard anything about this? Although this setup would probably exceed most average peoples wallets for such little gains in only the first and second gear it would still be wonderful to see on our Z's.

In case you didn't know, a Twin charged setup is when a Turbo and super charger are used in the same engine. It gives you the best of both worlds. Low end torque and high end HP. I have also heard the setup can actually give insane gas millage on most cars that are driven 'normally'. On top of that it typically gives an engine the most beautiful purr you have ever heard. Here's a Lotus Exige with a twin charged setup. The sound is just, amazing...


550hp 1.8 ltr @ 32 psi Turbo Supercharged 2100lb Lotus Exige.

wow thats amazing

That is outrageous.

Nice...that guy must've run that road alot of time before he did that..one wrong move and he's goner..

Its amazing to see how composed his car is...simply perfect

That is the most amazing thing I have ever heard. It's unbelievable how good that sounds :drool:

I followed that guys build. thing was a BITCH to tune so it might take more than Uprev to handle that kind of work.

insane!!!!!!!

550hp in a 2100 lb car? just insane........

That's an impressive car.

:drool:

So much time and money put into getting this beast working and they couldn't fix that LCD screen on the dash...... lol!

nothing wrong with the LED's they are just pulse width modulated at a frequency that is not working with the FPS of the camera. Much like an old computer or TV tube when filmed.

Pulse-width modulation - Wikipedia, the free encyclopedia

Here's another vid of that rocket. Why is it that no one else is on these roads???

YouTube - Lotus Exige.......It's Done

WOW.. holy Sh*T! :eek: The sound :drool: two :tup::tup:

Hot DAMMNNN... That sound is straight out of a scifi movie. For a second, I thought the flux capacitor was going to kick in when it hit 88mph...

I guy tryed to twin charge a Evo but never really got it right. Blew 2 motors but did dyno once 500whp at I think it was 4k rpms . Then gave up on the project:shakes head:

Isnt that a Toyota Celica GTS motor??? I Could sware it is! I knew they had one in one of the lotus cars. Sounds like pure beautifulness to my ears! To bad you could not get that sound outa the z. Too big of displacement to sound soo elegant twin charged or not.

Usually its either the GTS motor (made by yamaha) or a honda k20a.

I think it is the Toyota motor, could be wrong though.

DAMN! I wonder how fast he is going, to me it seems pretty damn fast. and with a car that small doesn't it need a roll cage?

Its a 1.8L toyota with a yamaha designed head . the motor sucks, and Is the main reason I would never get a lotus. The K20 swaps are nice but it runs close to 20k for the swap. This one seems nice though.. twin charging is what the lotus has been missing!

o.o i .........dang

Looks like GMR, backside of Mt.Baldy, I've been on that road several times, last time I was there, I did the whole 22 miles and only passed one car, it was awesome. The front side is only 13 miles, so most people avoid the long way.

Twin charging the 370 would be a very interesting and costly venture. There are two ways of doing this. The first way is compound charging as the Lotus pictured is set up. This would be feeding the turbochargers into the supercharger. This would results in very high boost pressures. Remember 10psi from the turbo system plus 4psi from the supercharger does not equal just 14psi. In a compound charged system the supercharger would be further compressing the 10psi from the turbo system. Hence the compound charging name.

The other option for this system would be to use a bypass valve to allow the system to use the supercharger for the instant response in the lower RPM's but then switching over to the turbocharger system in the higher RPM after full spool up has occurred. Finding a valve that would work well for this, and flow enough air for the Z's engine would be difficult. In regards to this working with the GTM kit it would be tough with the Rotrex charger, or even the Vortech found on the Stillen kit. This would work far better with a charger that has the magnetic clutch in the pulley (think AC compressor) like some of the Mercedes, AW11 MR2, and the Ogura clutch units.

It does look like the GTM SC and Turbo could co-exist on the same engine, but i think the only way this would happen would be to take the compound charging route. In other words time to lower the compression. I would love to see it, but someone would need some deep pockets to pull this off.

For my money i think i would go with a twin turbo kit, and use a small nitrous shot to spool it (assuming it needed the help spooling). Usually once the turbo's are spooled they aren't going to drop out of boost until you shut down the throttle.

ronin is the crazy old man who owns that lotus. you can learn more on the forums here...

and here's a pic of that car...

I was actualy wondering about this the other week, if anyone was going to attempt it. ZZP did a twin charge kit on a 2005 Cobalt SS Supercharged. It made 465hp on stock internals which is amazing and had no lag at all. There kit was going for $7000...although that was on a cobalt, not a 370z..lol

STis have been twin charged as well.

... and GT500's.

I beg to differ on the "1.8 sucks" comment. I had a gts I loved that car and that engine... and yes it is essentially the same engine as the one in the GT-S Celica's however they are usually bored out a little bit to 1.9 I believe.

i don't know about the engine internals varying from the Celica version. The Lotus does however have its own engine management, and what is most likely a more aggressive tune than what Toyota put in the Celica.

the car looks amazing in the video specially the sound
