Custom Plenums

[Silent]

I was reading through the for sale section and noticed a couple of threads selling modified standard rb25 plenums where they've made them front facing plenums.

Is this possible or have I missread it?

[heslo]

It's possible, doesn't look neat but does the job

[Silent]

Anyone got pics? Links ? Any Info would be great!

this is the best i could do...

[Silent]

Thanks Cjet,

This is what i was after,

Does anyone have any comments on doing this? It wouldnt be very hard to do with the right tools.

waste of money.

When you can make over 300rwkw on the stock one

why change it? Doesnt pose a restriction or hinder the car at all

[ctjet]

i would assume that most people do it for the aesthetic reasons... with cooler piping and the such

[Bliksem]

From what I've read people do it to reduce the cooler pipe length and increase response.... at the same time I've read it reduces torque and increased the power band up higher in to the rev range so weather it works or not im not sure.... most likely a decent tune needs to be performed after installing one.

Well It makes sense less intercooler pipe less space to fill? Not to mention top mounting turbos.

[2BNVS]

the stocker is great for decent power, but the less piping the better/neater, plus the pipe does not have to cross over a hot engine with a front facing plenum... on a relatively stock motor a bigger plenum can hinder performance, but on say 350rwkw+ i believe it can help alot

ben...

Soon as I can get another plenum Im going to try this, Should look pretty nice polished properlty.

[ctjet]

it might look dodgy if you dont properly fix the old intake hole. the way most people seal it looks horrendous

[Silent]

Yeah , Im going to do it propertly mite even look at powercoating it.

Is that because the flow of the standard throttle body?

eh? You dont read/understand english very well.

Might i suggest you go and re-read the thread

We are waiting for a lot of R&D to backup the dribble you carry on with.

[Silent]

Im guessing that the size of the throttle body/flow hinders the performance ?

[Bass Junky]

The Throttle body doesn't hinder performance. Under pressure the stock throttle body can make plenty of grunt.

What limits the power output with the factory intake plenum?
