Re: BulePrint RBC port&polish to 70mm.

Do you happen to have a dyno graph of before and after?

All I got was paper copies of the dyno's, so let me see if I can come up with them, or something to post. Most say posted dyno doesn't mean much, it's how the car runs that counts. But I drive the car as a daily driver, when the roads aren't wet. I also drive to the IFO races I run in.

How much did it run you to get it port and polished....?
Ok $500. or $1,600. for some top named mainifolds. The RBC ported about 330 cfm, one named manifold about 340 cfm before porting.


Upcoming k20a.org Project IPS K24A 101.6mm x 89mm
Thank you

IPS manifold alone on the flow bench was at 330 CFM average..

After port matching with the head, the mani alone flows at 394 cfm

Thank you Stefan!!!!

Jesse,

The RBC has a small plenum volume and will start maxing out at high rpm. Thats where the IPS manifold will pick up power and outrun a ported RBC.

trust me when I say this... what a manifold flows on its own is not as important as to what it flows connected to the head...

Like I said before, you can take a big drill and make the RBC flow 500 cfm.. it doesnt mean anything on its one.

The biggest advantage I see is the volume of air that it can hold at one time.. The IPS mani's plennum is huge

Yes nikos, IPS manifold is a top level manifold & RBC is a med level manifold. I am giving my :up::up: to Blueprint for taking me, to my next level in intake air flow. I am happy with my up-grade. Yes there my be another level later, after porting my head & new valves. Cost for RBC from stock 64mm $250-RBC manifold, + $500-porting RBC to 70mm,+ $70.-70mm Karcepts adapter,+ $300.-70mm Shunk2 T/B = $1,120. & $500 retuned, $1,620. total for about 10-15 whp.

Next level about $1,200-port my k20a2 head, $500-new after market 1mm over valves, = $1,700.

Ohhhh, ok. That power makes sense on your motor. Is there a reason why your running a short intake? I think with a tuned length cold air you can exploit the rest of the intake setup you have... Have you gone that route already?
