Got Over 400kw Atw?

[R32 Zilla]

So close ! ........ 390kw from Jun 2.7 and -5's. This was on a mainline dyno. Last week I ran 130mph so I think it is making every bit of that power. Anyway I shouldnt be posting in this thread haha.

What cams and headwork?

Boost?

Who tuned it?

[vg216]

My GTR 404rwkw @23psi tuned by Unigroup

RB26

twin garret 2871r

hks stage 2 cams

ported head

hks 280lpm pump

[R32 Zilla]

Head was fully reconditioned but no porting was done. Tomei type B valve springs and new bronze exhaust guide inserts. Grex 264/9.3 cams. Tomei cam gears.

25psi boost.

BP 98 fuel.

Built and tunned by Jim at Dart Automotive.

It has plenty of response and mid range. Very happy with it.

This is my build thread but it hasnt been updated with new dyno graph above.

Nice work man. How rich did he tune it?

AFR's sit ruler straight on 12:1 at all all points on full boost. Blows a bit of black fuel smoke. Nice and safe.

R32 Zilla ..what exhaust manifolds are you using ?..& have you done any porting on the turbo exhaust housings .

All standard manifolds. Standard 2860-5's. No porting. HKS split dumps.

good work, its definately got a 10 in it with a good driver

definitely!

i did an 11.1 with 320awkw (if i changed into 4th across the finish line & not hit the limiter in 3rd, it would have been a 10)

with 390awkw it is well truly a mid 10

Give us a chance! haha. I only got 3 runs the other night before it rained and it was called off. I was getting faster with each run. We were slowly dropping tyre pressures. Got an 11.21 @130 on the last run with a 1.78 60ft. As some of you know its not as easy once you get up around this power especially on street tyres. With my old motor it was just a case of giving it everything to reach its potential. But yea it is easily capable of a mid to high 10 with either some more practise on street tyres or a simple tyre change would get me there.

This is no drag set up though. If I wanted it to be faster over 400m I would have chose different turbos/turbo and made 500kw which this motor could easilly handle. I chose the -5's for response on the street and for hill climbs and the circuit etc. I like corners.

Oh and the 390kw is RWKW not AWKW Marko. I dont think that makes a lot of difference but lets not start that debate again haha.

[Marko R1]

yeah we've put this awkw v's rwkw behind us now

i should add that i was running drag radials when i ran my time

[DVS JEZ]

i ran 10.98 @ 130.7 mph with 405awkw, on old street tyres, federal 595s. and worn out os giken clutch,

last week with 285kw stockis R32 GTR just power fc,exh, steel wheel turboes, 3/4 tank of fuel, spare wheel, jack, all interior in etc ran 11.7 @ 118mph on my 2nd run, got booted out cause i didnt want to renew my ANDRA licence,

i spent over 45g on my last GTR to get 10.98, my new GTR i have spent maybe 4g, big difference in costs to get from mid 11s into the 10s

oh and i didnt mean to start a big war on rwkw to awkw

Just a question that is kind of related to here; in my quest to get to 400kW ... does anyone know if you can use Supertech bronze manganese valve guides with Ferrea oversize valves? Ferrea don't make any for the RB26 apparantly.

I dont see any reason why you couldnt.

[Angus Smart]

I may actually be able to join this list very soon!! things are finally looking good! tho it may be steves 500kw club!

i will be going GTRS on a built 2.6, 280 10.8's, E85, CR box with as much boost as it will allow 2 bar close.. then back it off to keep things together haha.

[N1GTR]

I'm sending the car away tomorrow to get the exhaust fitted and an oil air separator made cause what's on there now is terrible.

Then, straight to the dyno

[N1GTR]

What's a CR box?

Croydon Racing?

[NXTIME]

close ratio

[N1GTR]

Oooooooh of course

Silly me

So is that yor old trust box then?
