What I don't understand is why 2 of one turbo doesn't give the potential for twice as much power as one.

Tony G · 6th August 2006, 04:05 PM

Probably to do with the fact that twins need 3 cyls each so wont spool the same as all cylinders pushing the turbine?

What i'm wondering is how come no one has gone balls out and twin turbo'd the GT-R using two HKS T04R/Z turbos lol. It ain't that much of a stretch from twin GT3240's and is a little bit of a step down from twin GT3540's. Anyone really know of someone who has that or even flirted with the idea?

Because it would spool at about 9 million rpm?

If you read this thread, there are details of an engine with twin T78's which are even bigger than the T04R/Z

RANDOM PICS: RB30 from Tomei,OS etc.

Its actually already been done by a tuning company in Western Australia. Name of the tuner escapes me but there were some pics posted on the Net of the setup.

Cya O!

X - speed
HKS 2.8 L
Twin T04Z
N1 block
Full boost at just under 7 K

the aabove info taken from High Performance Important GTR special number 5 (issue 59).
Its even got your car in it hipo

RBnemesis13B · 9th August 2006, 11:46 AM

Wonder what kind of power that setup can dish out properly. I've seen twin T78 BNR32's already so twin T04's won't be that bad. Using it as a street setup is the problem, but if it was a time attack or drag car then wow.

I was just gonna come & post the link.
885.8hp to the wheels @ 1.9bar w/ 110 ocatne. What if they used the 114 @ the same level? I just like that they're different. Havent seen any times though.

Is that for the twin T04Z ?
If so that sounds pretty poor, since mine makes 650 atw @1.7 on 100RON with only one T04Z.....and Tim's Nur is even better IIRC.

I suppose it has a lot to do with the tuning.
It SHOULD produce more than that.

Bean · 11th August 2006, 05:55 AM

That looks like a good idea for the next upgrade....
...no, must wait for VNT

kingsley · 11th August 2006, 07:28 AM

I expect those twin T04Z turbos could carry on supplying boost at that level for a few more thousand rpm. If the engine could rev higher while still flowing well then I would expect power to be much greater.
