nah each trumpet still has its full top they just sit over the top of other ones bout 15mm clearence between them, yeh 2 centre runners are shortest, 2&4 are next then 1&6 are longest runners

Got any pics of one of these on a rb25det? (in a vl)

You mean like the picture of the RB25 in the Vl about 10 posts before yours on this same page?? 6BOOST

Just made 378 rwkw on 23psi, pump fuel today Another interesting thing, is the map sensor for the microtech is is spot on with one of these manifolds all the time, and on the bresciani plenums, it fluctuates everywhere around the mid range, air flow is a funny thing cheers darren

will u sell the plenum to run on stock ecu with all the fitting needed to plug all that **** into an just the cooler pipe from the t/b to the cooler bye nechance?

yeh can make it so it takes all std iac valve etc, cooler to plenum pipe $200, plenum $600

Thx Jamie Just got all my goodies, the welding on the plenums look great!, i took my plenum to my local polisher and me and him agreed not to take the welding marks of becuz its so Pro, Nice Job mate! BTW: Will Deal with again, work is so High Standard. and well worth the money!, just waitin on the XF's to be sent down to me and u will see the pics of my car completed with the whole JD Cistom Kit on!

when custom plenums first became popular, i read that the greater capacity of air initially available (being 6L in this case), gave the car better torque(low down power). though later i have been reading by people on here that having one of these plenums makes the low down torque worse, but instead gives it top end power. can you please let us know which is true, as i just want low down torque more than top end power. or does it benefit both? also how do you change your oil filter without taking plenum off? thanks

benefits both,torque and top end power, can change oil filter no problems with plenum on.

Just waitin on my XF to be sent up to me, and my plenum to be polished and i should have my car bay pics up!

JD with the rb25det plenums, do u need an aftermarket ecu for them?

i wouldnt think so phill.....u are only changing the shape of the plenum when u think about it....thats if all std iac valve and vacs etc are connected....

yeah i know but its for a rb25. But i want the plenum sooner because its not that expencive but then im going to get a microtech

PM sent mate!

sent ya a few pics, and can be made to take all std iac valve etc for rb 25.

hey how much for a polished plenum with throttle body and the work for rb30et?

i just got my plenum polished by my local polisher, turned out Great!... will host pics soon!

here is a quick snap shot of my local polisher work :p Some original photos have not been recovered yet.

Phantom T, use the NA runners if you want, works well, And a plug check reveals that this plenum gives a even burn to all cylinders. cheers darren

heres a pic of the new mandrel bent piping kits im doing to suit these plenums, and im not suppling the xf throttle bodys anymore with the plenums, too much hassle chasing them up.
