Blacktrax Intake Manifold Spacer

[SuperTuner12010]

Is there enougg room to double stack these?

I was thinking

PLATE----PLATE----IAB
or
IAB----PLATE----PLATE
or
PLATE----IAB----PLATE

Is there enough clearance to do this?
Also why not just get the IAB's off another intake manifold...take the butterflys out and you have the same exact plate and you can get the rods at a hardware store?

this is looking sweet i'll take any extra hp i can get

U got the definition of doublestacking wrong, what ur trying to do is triple stack. I don't know what would happen if u tried but u will have to get new hoses as they are pretty stretched out as it is and i dont know if it would clear the hood.. If u read the whole thread someone already did use the oem iab palte and gutted it. Only difference is one helps with cooling. If u don't have an oem plate this is a great alternative

only when u buy two of these spacers, if u only buy one u have to tell them to include them, or u can buy them at your local hardware store. Look at my DIY thread and the size of the bolts are there just read the second post on it.

IDK couldnt find the DIY thread for the bolt size i went and found the thread are 8x1.25 but how long? thanks

i'll ask and see what size they were. it says 100mm so let me double check when i get the chance

did u read it says no tuning done

yes I did...but you must have missed where someone here said you would need to re-tune for those numbers...and they have FAR more build exp. then me...which is why I asked.

sweet their it is thanks

I love how the peak numbers stay around the same rpm's as before double stack.

hmmmm...triple stack? if double does 5...triple!!!

Ok seriously though...if hood clearance wasn't an issue...possible that 3 would work?

Be awesome if you could tune when the plates open, might be able to lengthen the runners like that and have it work...but I'll prolly stick with the double stack for now.

you can

really? It's controlled by the mysterious black box (vacuum switching valves controlled by ecu) correct?

Also...would it matter where you place the butterfly valves? on top or on bottom?

The mysterious black box is controlled by the ECU.

[bcjammerx]

ah...a chipped ecu

Yeah, a chipped ECU for 100-200 bucks...
or a $2 relay and a modified adjustable shift light for 37 bucks.

So does anyone have their dual runner IM opened up to a single runner (like HondaFan81's white ride)? I want to do this for my built H22 head, and use one or two hollow spacers (1-hole). If you're not going to use the IAB system, I see no point in keeping the 8-hole screen, it is just more restriction. From the blacktrax dynos, it looks like low end on the single runner power is up to par or better than the dual-runner from about 3750rpm.

I am planning to keep the IAB system and add a spacer to my stock-ish daily driver H22. On this I am looking to put an 8-hole spacer under my ported IAB system, but I wonder if a plate above the butterflies would benefit differently.

It seems that longer runners still make more HP with this, be it from cooling or volume, or whatever. Shouldn't it be max HP to have no spacer plate at all?

Does anyone else wonder about these important things?

[totaldoughnut]

I was thinking the spacer would go on to of the butterflys also, to increase plenum volume. If the purpose of putting it on the bottom is to increase runner length then why not just install the h23 runners during the manifold swap? H23 runners are 1/2" longer.
