The whole functionality of it seems correct. The only reason I am hesitant is because I have done tons and tons of searching and no one in the honda community has tried to run it. I kind of don't mind being the guinee pig because the concept seems correct. BUT I AM STILL ON THE EDGE

Anyone with any input/understanding of the product/experience/wisdom/etc please chime in.

 

i know alot of supras ran them,, try it out

 

I have a friend that ran one on his rb25 260z and it mad an extra 30whp and tq under is power curve. It was very nice!

 

I think I am leaning towards that side!


Do you know how much sooner? I have only heard/seen positive things so far.

 

It wasnt a ton. It was around 600rpm sooner but it built in a fatter hp and tq curve from about 1500rpm lower (than previous full spool) and gradually increasing upto the new full spool.

 

you run stand alone ems right? is your boost controlled by ems? if so you can do this with the mac solenoid. you just control how aggressive it spools the turbo by manipulating the wastegates to open later/slower not really sure. but i no the end result lol. i run aem ems v1, and it does it.

 

I have seen the valves along with the dyno charts that show they work. However, my primary concern is not whether they work or not, but the effects they have. Due to the design I would think pre-turbine pressures/turbulence will become an issue rather quickly. I wont say whether or not someone should run them, I just wont use them myself without more testing.
