Most Powerful Rb20?

[RB30-POWER]

Hey Guys,

Sure someone will know here, it became apparent to me a while back that I have not ever seen (from memory) an RB20 make over 300rwkw?

If anyone has a link to vid of one making some good power let me know please.

Like a few months back, I went to a dyno day, a Silvia or some crap rolls on, pops hood, RB20 with a great big f**k off turbo, thought, ok here we go, this should have some balls, couldn't even crack 280rwkw, WTF?

Is it no one modifies these engines or can the head not flow enough air or something without big $?

What were the old red tops making back in the Group A days with the T4's and race fuel?

I know the practicality of modding to have power like i'm talking above is not very great, but how often are extreme car mods ever practical anyway. Have the Japs bolted a T88 to one or what?

Cheers

Roy on here has some 260 odd kW at the rears. i personally havn't heard of much drastically higher than that.

rather than spending dollars on making sure the engine is healthy up at the high kW range, people would rather go with the RB25 or RB26 as it's easier to acheive. though, it would be cool to see an RB20 hit the big 300.

the lower compression engine would see some bad lag with a monstrous turbo.

i make 241 rwkw. i have read on antilag that someone in wa made over 300kw with stock internals

[evil_weevil]

legend01 makes quite a bit.

Have a look in the forced induction section - thread named "top rb20 club" or something

[lingeringsoul]

lol legend01.....that is one insane insane car......the power delivery curve is............well.....insane.

[RB30-POWER]

Forgot about that thread, ok a couple of guys border lining 300rwkw/400hp...

If anyone has link to dyno graph of legend01, link me please. (couldn't find it)

No one seems significantly over it, i'm sure there has to be some offshore cars that do something noteworthy.

I don't care if its a built engine or stock standard, if it runs race fuel or pump, I just want to see one that makes some numbers one way or the other for the record.

Cheers

since jan this year, started off with a 20 psi tune made 335rwhp, then went 24psi and 366rwhp, then fine tuned a bit more after replacing the inlet mani gaskets went 385rwhp on same boost

motor hadnt given up or showed any signs of it being on the way out so we went nuts and did the big boost tune haha

motor is still going strong and receiving a new turbo setup

[-_-StRyDeR-_-]

as they say...a motor is only as good as its tune, and you must have a pretty good tune there. top work!

309rwkw, I believe this figure was taken from a member on the 31 forums that still races one of the gibson motorsport 31's.

[RB30-POWER]

so does that have cams done on it at all?

what fuel?

those injectors must be near 100%?

nice work either way

nah no cams for those figurs not even a set of adjustable gears. bp ultimate 98 ron no additives

injectors soposidly still have room to play, im considering going some 550s with the new round of mods but we'll see how i go

thanks mate

You could get over 300rwkw, you just need some well through out head mods to get it breathing a hell of a lot better so that you'd have a car you could actually drive.

There are a few cars in the 240-280rwkw mark no problem.

Im sure you could put a larger turbo and a bit more boost for the numbers

The heads obviously don't flow anywhere near as well as a RB25, so a big outlay there would get you over 300rwkw as RB20 bottom ends seem to take a fair beating in stock form no problem
