Forged Rb20 With Gt3540

[Ryanrb25]

true cubes, like i said its merely a test car....we wanna see what we can get outta it.

and video does no justice to the sound of this thing...its got a fairly quiet exhaust on it anyway.

oh and dyno is tested and proven. Its 2000hp rated with twin retarders. so its up to the job.

its got like a truck muffler on it i kid you not the muffler is like 3ft long baffles it heaps

[Proximity Motorsport]

f**k yeah thats awesome. Should try out a cheap ebay manifold once you think its at the limits and then see what increases you can make, if any. Pick up manifold for $200 these days

umm yeah i forgot about the 20psi before the cams thing.

Either way its making some very respectable numbers.

Keen to see it out and about some time.

lol u said it CHEAP,

if u want power u need sumthin decent, not ebay crap, my mate got one and the welding is so dodgy lol

[VB-]

good numbers from a 20, i wont go as far as calling bs, but it does sound like an excited dyno

what cams are they?

[Ryanrb25]

we've had a few 300+ cars on this dyno and the same car's on willal's dyno that had a 4rwkw difference if that's any clarification....

The cams are JUN cams...dont know any other specs other than 264duration..will find out more.

[Madaz]

we can allways chuck my car on after Micheal does a run and if i pull same or very close to boostworx then we all know that Dyno is still in calibration

[dangerman4]

Dyno sheet or

Youtube....

Whats with the spike at the end bumping power from 270rwkw to 297rwkw???

Essentially the power curve...

3000rpm - 35kw

3500rpm - 40kw

4000rpm - 50kw

4500rpm - 70kw

5000rpm - 95kw

5500rpm - 130kw

6000rpm - 190kw

6250rpm - 210kw

6500rpm - 240kw

6750rpm - 260kw

7000rpm - 270kw

and then it spikes to 297rwkw.

It seems as though a .63 AR housing, or maybe even the .78 twin scroll would do wonders for this setup. Is there any plans to put a smaller exhaust housing on in the future?

Great work

[frogstomp_R31]

nice work guys .

i run a 3540r on my rb30det in my 31 ..but on a 20 wow lol

[Ryanrb25]

i see what your saying cubes, none of our other runs were like that, we did about 200 runs that day and just so happens the one he filmed was like that...never noticed it before...ive got a dyno sheet ill put up with 288rwkw and 291 without any sort of imperfection...give me a sec.

[rad100]

anymore updates?

[Dobz]

That turbo is as about as well matched to an rb20 as a midget is to a sumo.

I'm guessing you were bored and had the turbo just lying around and wanted to see how much power an rb20 can take. right?

None the less it's good to see someone pushing an rb20 to its limits.
