Plenum Spacer... myster mod from the dead.
OK, I have been reading and researching long and hard. This company has been mentioned before, but I don't think it really went anywhere. PLEASE NOTE: I do not work for these people, I am trying to see if they will develop something for us. I personally think there are gains to be had as some of you older acurazine members remember the Myster Mod / MM / RES. Maybe we can make this happen with enough fascination.

look at the top end gained. scroll further down and look at the g35 dynos, the TQ gains are enormous. they were looking at 15-20 tq gains. and it isn't just top end, for the most part there is a gain across the whole power band just like the spacers / pulley.

I apologize if I'm just over simplifying way too much, but is this essentially the thermoblock spacers on top of two other components to get those kind of gains?

ALL SHOW AND NO GO
i heared about this a while back ago but always thought some one just invented it in there backyard and called it a mystery mod. i always wanted to get one but never knew where to get it but i dint really know to much about it exept that it gains alot of hp and tq

You mean this, Rick Case Mystery Mod failure number 1?

I would have liked to see it dyno'd without the imrc being activated. did scalbert try it both ways?

it's kind of annoying that we know there were gains from it, but it went no where. someone just needs the know-how to figure it out.
edit: didn't nashua also try to duplicate it? they just made an aluminum spacer between the cover and the manifold.

maybe not exactly popular 'sport' cars, but fairly popular to mod. i see at least 1 post a month of a new guy complaining there aren't many modifications. i bet those guys sell their CLs and buy a G35. it's all relative, but i'm sure we could muster up 15 or 20 people between CL / TL to buy this. just my opinion.

Sigh, the one that got away . . . before it ever was 
There was more to the RES design than just increasing the plenum volume. RES utilized some sort of reed valves within the RES - hence the name resonance enhancement system . . . I believe.
So the straight forward design by Scalbert did not incorporate this and was simply a spacer. If syncivic would have turned over the design or sold it with some sort of right, Scalbert probably could of built one.
Anyway, unless someone understands how the reed valves incorporated within such a design would have benefited our engines, this is still the product of the living dead.

i just feel that if an acura tech can figure it out, someone else can. people bring it up all the time, simply to have people post, search, read FAQ. i was around after syncivic and his 2 mods, and i understand they went no where. i'd rather take some engineering knowledge and develop things.
ok: http://en.wikipedia.org/wiki/Reed_valve
my guess: enlarged the plenum to adapt this 'reed valve' which is basically based on air pressure. simple enough? he encorporated enough 'space' inside to retain the same amount as stock, but now with these valves in place, as pressure increase inside the plenum, the valves open and increase the pressure even more.
"They are pulled open by a partial vacuum created by an overexpansion of combustion gasses. The open valves allow a charge of fuel and air into the engine, which explodes, increasing the internal pressure and closing the valves. The cycle then repeats." - this is used w/ fuel, but i feel the concept applies.

However, I'm not sure that those modder minded types will go for these cars like they do for others. The only hope we have is if the Honda based cars with the V6 like ours drives some demand.

There has never been 1 indication from Acura that any of the performance mods have had any bearing on the 3rd gear clutch pack issues.
Bottom line is sales... why would you ever consider manufacturing something for a model that, not only didn't sell well, but was discontinued?
