xXLoganXx's Intake Manifold Results

[Natewood70]

so xXloganXx u said u had a tune this past monday, how did it go?

[gtcompscientist]

Man... that thing looks awesome. I'd like to see what kind of a difference that has made at the wheels... Definitely not a project for the faint-hearted!

[TUKO316]

thats looks like a great mod. i seen someone do the polishin job on a maxima. i always thought bout doin that too.
Can someone fill me in on what that butterfly thing does? would removin it have any negative affect on the engine i.e. engine damage or anything?

[SmokeAlti]

Nice work bro..

[froedrick]

I may be some sort of a dumby, but how does the engine run with the butterfly removed from the power valve. The butterfly is what meters and measures the fuel/air mixture, doesn't it? I'll take it out if it works; I just don't see how it could. Help!

Your car is no faster with the butterfly removed. It feels faster because your mid-range has gone to crap with no gain in top-end power.

Take a peek at the dyno sheets in the other IM thread. You are incorrect.

Jime also had his highest Mph in the 1/4 with this mod.

Here is the link I was referring to. Check the dyno numbers from kev....

And that's with JUST the powervalve removal. As you've noticed, low-end torque suffers and you lose a little bit of low-end too. But you lose the typical VQ VIAS dip at around 3k and it's nothing but gains until then. I've been considering doing this modification (just removing the valve) but haven't had the time.

If anyone is interested.. I can put some cash down for maybe someone to make me a plate to cover up the valve. PM me!

Not need for a plate cover. Just use the stock one and just remove the butterfly bro. You won't regret it and it takes all but about 5 mins to do this mod...

So wait hacku that whole piece that you are holding up is the butterfly or the gold thing is? And what you just unscrew the 2 screws on it to remove it thats it?

[mohav]

I removed that valve today... it wasnt easy getting the three 12mm bolts out because the harness is in the way but it helps to take out the two hex screws first. I capped off the vaccuum line and made a block off plate out of lexan with honda bond for a gasket. Worked like a charm and I think i feel a little bit of an increase.

Also made that Home depot catch can, it cost me $13

[Big_Lunn]

ok ok , im not sure why u guys are installing these catch cans. What does this do? from what I've read, its to remove oil going thru the intake correct?
How many places can u install these cans?

Also, does anyone know the reason why that golden flap is even there on the upper plenum? The purpose of it is to.......

[mohav]

logan, did you just can off that vaccuum line as well? or should i just route it back it somewhere?

[bigirish]

Cap it off.
