Most Powerful Rb25 In Aus?

[MR 33]

Anyone have any ideas on what the figure may be? I done a search but the last topic is 9 years ago so I think its slightly outdated lol Thanks anyways

[Super Drager]

I'm guessing this is yours then

Not sure whats the most powerful but there was one in the 9's a while back?

[MR 33]

Lol yes that is mine. Hmm not too fussed on quarter figures coz with slicks and an auto you can do magical stuff lol I know dynos can vary but would like to know a figure.

MR33 your car sounds awesome man - what the hell you do to get it sounding like that! Lol

[MR 33]

Lol thanks mate! lots and lots. So no one knows any big power rb25s??

[Ben C34]

nope. no one makes power with rb25s!

I have in my head these guys claimed something near 600rwkw for this - but can't find the reference. Can't specifically remember, but it'd have to be pretty up there... sticky tyres and an auto doesn't create the power needed to get a Skyline to over 150mph in 9s flat, that engine is making serious power.

Have you hit the dyno again?

Have you had new numbers

[WMDC35]

highest one on the dyno I use is just over 500rwkw

mph v weight is a more accurate hp measure than a dyno. slicks and auto have no bearing on trap speed.

Rb25s dont make power?? Lol ok

My car might be back on dyno this week

So you're saying a car doing a 1.5 60ft time will have the same mph as a car with a 2.2 60ft time?? I dont think so.

Awesome, good luck! Will you upgrade the turbo if it doesn't make much more? I'm still iffy about the compressor in that turbo being able to make a lot more power and interested to see what happens.

In regards to the trap speed.. depends on what the cause is of the slower 60ft time... I know people who have gone from 2.2 to ~1.6 and the trap speed hasn't really changed appreciably... I guess see it as being the difference between doing 0-200kph in under 11s, or over 12s

[MR 33]

Thanks man. Well being a custom wheel it is unknown what it will do. It make 530rwkw very easy on only 24psi with huge intake temps. Now I have new plazmaman cooler we will see what it makes on 24 again and on 30 plus psi.

[MR 33]

Good to see you deleted your comment about 25s not making power. Idiot.

[Dose Pipe Sutututu]

nice.. I heard you visited Alex & Henry not long ago

[Lithium]

I was working on the theory that it's based off the 52trim 94mm compressor from the GT4094R (~80lb/min), and figured you might make 520-540rwkw before the first tune if it was that compressor. Soaring intake temps at 'only' 24psi isn't normally a good sign for compressor flow, but hopefully it does just turn out to be a really poor intercooler.

[MR 33]

Yes alex and henry are great guys!

Its definitely the cooler, will have results with plazmaman soon. It made 485 on 21 then 515 on 24. Let it cool for 2min and it made 527 on 24 again. Id be very surprised if it is near maxed out

The highest out put RB25det motor I've seen is 900HP from Nisma performance center.

I'm currently doing 490rwkws I don't think the rest of the hardware can take it any further. A list of your mods would be helpful.

[MR 33]

At the wheels?? That is unreal! My mods are all listed in the projects/build up section.

[hypergear]

Nisma youtubed a 9.9sec run in a R33 Chassis, Rb25det 900rwhp (671rwkws) was in their description. There were no additional details for their build.

Very interested in seeing how the results go! What is your target?
