Twin Charging!

[Oblivion]

Ok.

For starters does anyone knows anything about twin charging, and does anyone know of anyone who has heard of anyone doing it on a skyline or any nissan say rb engine? Was having a brainstorm this night and thought it would be an interesting topic to look into. Ta.

having a turbo and a super charger, i assume one feeds the other, about all i know...

[Duncan]

I know Nissan sold a twin charged micra, there is some info on here about it, and there was a discussion about issues with twin charging ages ago.

Try a search for supercharger see what you find

Actually....one of Trusts OLD demo R32 GTRs was twincharged.

running around 700ps from memory.....

There have been a few discussions on many forums regarding this topic - eg:

i have Twincharged a 4agze with a system i made up .. the Secret is in the Turbo to making it work . i love the system due to the wide fat torque band ,, you can make more Hp with just a turbo , but you dont get the broad torque band . power band is more like a v8 engine with instant torque on tap .. ,, here is a web site on a subaru systemhttp://www.forcedairtech.com/

Youd want a one way valve on the pipes from turbo wouldnt you? As the supercharger builds boost it will be pressuring up the pipes to the turbo..adding lag and not good for turbos?

[Whale_Ryda]

27psi of boost from a blower

Thanks for that pic PHaT MR30.

That is a help to understand how they did it. Ta.

say goodbye to power steering tho

You would set up the supercharger on an actuator which opens a valve for the turbos to take over. The supercharger will boost instantly giving you awesome take off, then when it reaches it's desired pressure of say 10psi the actuator opens the valve for the turbochargers from then on. That way you don't get reverse boost while the turbos are spooling and the pressure will only go one way. I have seen this set up on a corolla before and it worked extremely well.

Nissan did it one the Superturbo March (in an issues of HPI). I understand some ppl in the UK are trying it. search the UK GTR forum.

That pic above is very impressive, I imagine it would be awesome to drive

[StavrosRB2630]

That supercharger on GTR pic is totally fake, no way a setup like that will work.

You dont need any kind of switchover point etc either, the transition point would be horrendous and a bit pointless TBH.

Easiest and best way is for the turbo to blow through a rootes style charger at all times.

Theres a lot more to it than that, but thats the basics of a good working system.

[Abo Bob]

There is a rotary in the current issue of Zoom that was locally built and has both. They have technical drawings and stuff as well to make it easy to understand.

[PHATR32]

i dont even think the above setup would fit??? would it??

it looks sweet though.
