Hks 3040

[kanny]

anyone on here running twin hks 3040 high mount turbos? interested in seeing what power they are making with supporting mods.

cheers

[GTScotT]

That's a lot of supporting mods.. 50k or more I think.

Your also talking something like 1000hp of flow, are you actually chasing that kind of power?

[kanny]

I am halfway through my build with these turbos on a 3ltr. Was just seeing if anyone has done a similar build. How lagging on a 3ltr what power at what boost ect

[GTScotT]

You will be hard pressed to find any on this forum with those turbos in a twin setup.

You would also assume anyone with those turbos would be thinking about power more than they are lag. Most people on this forum would consider ONE of them laggy making a little over 300rwkw. Two would be shy of double and obviously very laggy.

i knew a gtr with twin 3240's, still a 2.6 mind u. comes on about 6-6.5k from memory it made almost 400awkw on only 18psi lol. repsonse and twin 30anything shouldnt be in the same sentence. didnt see it wound up in the end tho.......

laaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaag

[wolverine]

[lotsalag]

the 34 that had that setup in it had a hollinger dogbox in it, still a heap of shit tho hahaha

Yeah single form you are in the 300-330rwkw region on PULP.

So two of them, 650rwkwwould be a rough place to start the guess work.

If a 3076, smaller than a 3040... comes on round 3000-3300rpm in .86 form on a high comp 3lt, you'd expect about 6000rpm in twin, which won't have high comp given the boost that'll need to be used.

Depends on rear housinsg being used of course.

Hope there if a rev limit of 10,000 at a minimum

You chasing 600rwkw+ or not?

Some people consider that 2530s and GTRSs and GT2835s and GT3037s can be a bit lazy in twin form on an RB26 .

I think GTRSs is as far as I'd go on anything with number plates even on a 2630 .

IMO from the GT3037/GT3076R and up is getting a bit extreme on anything other than a single purpose drag car . Like most I've read articles on the Japanese with their denuded slingshot cars but they are not something most would want to use for anything else , basically bloody useless except for the very rich on a drag strip .

It takes a lot more that two bigish turbos to make a GTR a drag king .

I couldn't imagine an engine that was a clapped out Camry one to 6500 revs then an unguided missile thereafter .

Anyway on paper the HKS spec GT"3040"R , todays speak called a GT3082R , is a better one than the one Garrett generally markets though they've been around long enough its exclusivity rights to be over .

I'll look up the numbers later so you know how to ID each type .

The only real difference aside from a HKS turbine housing is the compressors trim which is 50 on the HKS variant and 56 on the one Garrett usually sells . Same comp housing same center section .

MarioGTR may have at some point?

[discopotato03]

The cartridge numbers for the GT3040/GT3082R are 700177-9 for the 50 compressor trim HKS spec version and 700177-14 for the 56 compressor trim version Garrett usually push .

Sadly the 56T one was very common and there are a fair number of them in circulation .

My HKS list quotes the GT3037S 56T (port shrouded comp cover version same as GT3076R Pn 700382-12) as being 480 PS and their spec version of the GT3040/GT3082R (50 comp trim one) as 500 PS .

The reality of the matter is that half an RB26s 2568ccs or 1284cc isn't a lot to have to spin up a 500 odd horsepower turbocharger . Try to imagine a GT3040 on a Suzy GTi 1300 .

A purple one or a lime green one?

Either way it sounds great.

Bah, people put GT40Rs on Hayabusas - where's the sense of adventure

You find their sense of adventure in the orthopaedic ward of any major hospital.

ive heard Hayabusa turbo's are pretty safe. i mean they only lift the front wheel from the power until about 280km/h n then its pretty stable...

Exactly the reason that twins on a 26 will be sweet, just raise the rev limit another 7000rpm and wheel stand goodness at 280km/h.

I know someone pushing nearly 300kw @ wheels through a Hayabusa motor in a 500kg Toyota... that should be a little less temporary citizen-esque

[discopotato03]

Actually Busa engines are not in short supply 2nd hand . You go down to your local wrecker and say I'll have that one , they wipe the blood and hair off and box it up for you .

The point I make is that 1000 horsepowers worth of turbochargers is pretty extreme for a 2568cc car engine if its used on the street .
