6 is better

Hi .

what is it of the better surge tank (plenum) Intake manifold )) for the big single turbo 76 mm (ITS) ?

OR 6 throttle body better or single throttle body for big single turbo to RB26 DETT & better CFM ?

GREDDY,, JUN etc .. any mark ?

((((6 is better ? why? ))))

Thanks .

this is getting difficult to understand.

6 throttle bodies (or in your case surge tank/plenum) is better for response. standard RB plenums are supposedly quite good standard

lol :thumbsup:

this is good .

and if not it RB26DETT standard engine( strokerkit 2.8 HKS) with big single turbo 76mm ???

single throttle body or 6 throttle ? and why ?

thanks every body ....

with 6, pressure builds up in the plenum and is evenly distributed into cylinders when valves open. with a single, when the valve opens up it has to fill the plenum first and equalize pressure along all six inlets. with big turbo applications this is not really a problem because of the high pressure the turbo is pumping out. but for a more mild setup, or most setups, having a single throttle will mean less response. overall the reasoning behind using a single is to reduce turbulence and it would most definentally flow better for high hp apps.

youll notice most single throttle body applications have a huge ass turbo sitting on the other side of the engine. usually a 1000hp thing imo.

Thank you very much for this beautiful and cogent reply :P;)

      I would be very confident that they are the same parts (the 2 different SKUs). It seems very clear that you can drop the cam in the 2-way opening, or in the other opening. If you arrange it in the other opening in the same way that you see any other 1-way diff, ie, with the flat of the cam up against the 1° side of the opening, then it would work as a 1-way. It can only spread the ramps when driving forwards - cannot spread the ramps on overrun. It would then appear obvious that if you put the cam into the opening "backwards", that you would get the angled flats of the cam working onto the "points" of the 1° side of the opening, which would give you ramp spread in both loading directions. I do wonder if the forward direction of the 1.5-way config is equivalent to the forward direction of the 2-way, seeing as the cams are flipped and the angled surfaces on those would need to be the same on each side - AND - clearly when installed in either the 2-way or 1-1ay configuration they are not intended to work exactly the same (the ramp angles on the 2-way are 10° different between forward and backward, and the ramp doesn't exist in the 1-way config). 'twere me, I think I would rather actually have a set of rings that offered the 2-way with two different sets of ramp angles, say the 55/45 of the existing design and maybe a 45/37.5 combo for a less aggressive effect), AND another set of rings with a dedicated 1.5-way opening and a dedicated 1-way opening. The 1.5-way opening would actually have the steeper angle on the overdrive side that causes it to be less pushy than the forward drive angle, like you see in many other diffs. But really - if this Nismo thing is thought out properly and all those surfaces work on each other the way that they need to, who am I to argue?

      Yuh, but that one is NLA. There might be an equivalent, but I haven't looked.

      I know and understand they are principally the same. They both cause lock under decel, but the 1.5 nomenclature implies "half" or less locking force, or it allows for more slip or a speed differential between both wheels. Right now the driving manners with the 2 way is pretty rough on transient to full off throttle in the backroads. In other words letting off the throttle too rough is not forgiving, great for drifting, tougher for controlled grip driving.      Yeah, I have watched that video a couple times, I am more so just looking for the confirmation that both part numbers offer the same ramp architecture and are just different settings from the factory.     38420-RSS15-B5  38420-RSS20-B5
