Who made it? was it copied of anoter design? How do you know if it even works well?

[EXP19]

JD Custom made it on calaisturbo.com.au

he designed it

bellmouths inside

hav been proven that they pick up a fair bit more power n torque

his 1st ones he made leaned out in 5 and 6 as it was a square back, this is a taper back and it works like a charm!!

[INASNT]

Is there any flow tests to prove this actually works better than the stock one??

[EXP19]

i havent done any flow tests on it but i know people that hav used the exact same plenum but on n rb30 n it made atleast 15hp more at the tyres and a heap more torque

[INASNT]

Dyno graphs etc as proof?

Its good in theory but need some FACTUAL proof

[EXP19]

Bresciani runs the identicle plenum on a VL Turbo called BOOSTR

it made n extra 15-20rwhp and more torque

talk to them bout it as he uses them

i havent used the plenum

i know of a guy that uses it on his TT RB25 but no dyno figures

[webber]

yeah i know these plenums work, many guys on calais turbo.com.au have had great sucess with them, they are larger and eliminate the curved runners, increasing flow efficiency

[boostn32]

will this plenum fit on RB20 runners, or do u know if the RB25 runners will bolt on a RB20 head, help any one?????

I don't know if these things get much more outright power, but they do help eliminate a fair bit of heatsoak that most standard intakes on RB20/25's suffer from. That might be enough to give you a little bit more power and reduce leaning out slightly, but I find the better purpose of these plenums is to improve throttle response. I have a home-made, unscientific one and I don't suffer from any leaning out. I would get a more professional one if I was racing it or had more money, but for mild mods I don't think anyone is going to have any problems with this plenum.

If you're considering buying it, do it for the better throttle response, which is why I did it and I don't regret it at all.
