Will Standard R34 Gtr Dump Elbows Flow 450Kw?

[GD51LA]

searched but couldn't find anything

just want to know if anyone out their has pushed 450AWKW from standard r34GTR dump pipes

do i really need to spend 1k (or so) on the larger 76mm internal diametre dump pipes?

built engine 26..

$1000? Hpi dumps are $520 plus delivery from Nengun.

I'd say you couldn't find anything because when pushing for such high numbers with low mounts you'll be needing everything in your favour. How much of a difference they will make, NFI.

450rwkw from low mounts is a pretty big ask, not impossible though as obviously it has been done many time before. I do agree with what Piggaz has said, your going to need all the help you can get.

Summary of above:

Will they flow that much? Probably not.

Making 450kw from low mounts? You would hope you have every possible supporting mod to get you the best result you can, because you are asking for every last fraction of a HP.

What the rest of the setup like and turbo choice?

[Owgasm]

Tomeis aren't too expensive either.

Plenty of options.

[GD51LA]

setup im thinking of putting together.

built 26

-5s

270 cams/springs

port matched manifolds

3in front pipes, decat 4in exhaust

realistically that setup will be closer to 400, but want a 450 buffer, who knows, it might take 25/26 pounds then be closer to 450..

been chatting with a shop (overseas) who does allot of 800 horse twin GTX setups, he tells me the 34 dumps would flow that power, when asked the benafit of the larger hpi dumps, he says, turbo spools a little earlier

[Piggaz]

No need for cams that big.

[GD51LA]

It's a a street car, so it will spend allot of time "flexing" larger cam/lumpy idle is a must:) even if it mean a little less response

Got a vid of those Unigroup cams on idle

[Piggaz]

Pull some timing and fuel at idle. There is your lump/grump.

I'll upload one tomorrow when I get home if I still have it on my photobucket.

Care up share more info on the big power low mount Gtx combinations?

I don't have the car at home ATM but these are on E85. I specifically asked for the idle to be calm as we could get it. If I wanted it grumpy then it's just a few taps on the keyboard. On petrol it's grumpy as hell!

Sky engineering, look them up.

There is a bit of info and a few graphs up on here recently if you have a search. I helped with a 500kw twin GTX combo running factory airbox, manifolds and cooler/piping, so there is definitely more to be made if you don't mind a defect.

In your opinion, what do you think the factory airbox is worth at that sort of power level? I've always wanted to do a back to back with a set of pods.

[scotty nm35]

With the filter and lid dropped it made 20kw more, so there is a little in it with a good twin pod setup. (as long as they get cold air)

We don't get much of an option down here, the customer wanted it to look factory if he was pulled over, so it was a great result for him.

Unreal, were they gtx2863's or 67's were the -5 front and rear covers used? 500kw looking somewhat stock is amazing.

What car/ airbox was that ?

I'm hoping for that or close to it with the R34 box

[Piggaz]

I'm assuming it's "DAZ".

2.6, 63mm GTX, 260 poncams iirc.

[scotty nm35]

Correct, 33 GTR.
