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?

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.

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.

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.

That's the one, Piggaz. Thanks - good source. :)

Since there is very little experience with the setup I think they have a bit more work to do on the tuning and head flow. If twin 2835Rs can put down 740atw @ 1.62 bar on 100RON pump gas, the twin T04Zs @ 2 bar should be around 1000atw with drag gas (other things considered).
