Garrett 2860 -5 Turbo Killowat Potential

[GTRAAH]

Hi guys,

Whats the most someone has seen these turbos run in Kws? Meaning running healthy not about to blow up lol.

[R31Nismoid]

440rwkw i believe is at least one result that is up there.

[GTRAAH]

But how would that transform into AWK All wheels.

[Simon-S14]

in a GTR theres stuff alll difference between awkw and rwkw since its mostly a RWD set up until power is required to the front wheels.

[Travis Trayhern]

is that your car in a protek?

im hopping for 380awkw with my setup an -5's if that is you car in protek have a look at mine in there white r33 gtr give you an idea

[ali-turko]

in simple terms there is stuff all difference between rwd kws and awd kws

[Simon-S14]

in simple terms there is stuff all difference between rwd kws and awd kws

In a GTR anyway, in an Evo or a WRX theres a larger difference

440rwkw i believe is at least one result that is up there.

Question: Was that not with the 0.86 A/R rear housings?

[bradsm87]

My mate runs 400rwkw with a safe tune. That's with a JUN 2.7L stroker kit and Tomei 260deg 10.8mm lift cams on 20psi.

Nope.

HKS 2530's have done virtually the same power in a number of cars as well, being the turbos are same/similar/close enough, its easily plausible on a motor that is built right.

Most punters/motors however, 380-400rwkw. Takes something special to get much more

Presently at 570 rwhp (425 rwkw). HKS2.8L, 272 Step 2 cams, oversize valves, heaps of head porting and around 1.8 bar of boost on my dash 5's.

On 98 pump fuel that's about the limit of what you can expect from these terbs. (Hell responsive 'tho! )

I think Mark and Russ ran -5's on one version of their 32. 700hp+ on race fuel.

Shiitt thats like 27-28psi and those turbos can handle that healthly???? everyday drive ??

[TiTAN]

what part of the turbo do you think is going to break from using more boost?

It's probably at (or past) the upper limit of the efficiency of these turbos.

Engine in this configuation would be no problems for a daily driver as there is plenty or torque. In fact around town I'm lazy and normally only use 1st, 3rd and 5th gears. I have shorter GTS4 diff centers, however, so that makes a difference also.

Sorry not brake but comparing to life of the engine, is there much diff in using less boost or high boost if u have strengthend internals that is

[R31Nismoid]

Not really - if it build right.

However, my guess is your motor probably wont be going to such extremes unless you are spending some very serious cash.

Gav's motor isn't a cheap one, lots of work, effort and parts to get it to that level.

Most 'builds' around the 10-12k marker wont come close to a 2.8 stroker, bigger valves, head work and everything else.

[GTRAAH]

very nice... yeh well im up around 14k with tune and build lol Thats NOT with the internals still internals need to be done but then thats it.Another 6k and i should be happy BUt im not going to stroke it.. i wonder how much max healthy boost i can give it with out the stroker kit

[GT-R32]

So a $10k build won't be able to see over 400rwkw?

I need that sort of power in my daily driven GTR. You know, to overtake and stuff.

[ali-turko]

you need more like 20k from a stock motor, to make a reliable 400kw
