Steeda CMCV Installed

Acerbus · 05-30-2009, 04:09 PM

Ok, guys. I took the morning today to install the CMCV I had laying around. It was no easy task all by myself and being a complete car newb, but TacoBill's writeup had my back covered.

Took me about 6 hours between drink breaks, TacoBill's read up breaks, frustrated cussing breaks, tool search breaks; I bet I could do it in an hour now, knowing what I know. Assembled everything back together, connected the battery, loaded the revised Bama CMCV Tune and... started without any problems.

On the way back from my parents house, I had two chances to go WOT, and I did feel a bit more snap on my neck; but nothing jaw dropping. I also noticed the exhaust note changes slightly, specially on deceleration. It kinda smooths it out; you get less of the bubbly rumble and more a hummmm kind of sound.

I think at this point I'm ready to give up on mods that make you go

. I just haven't felt that feeling since I first drove my car with the CAI/tune.

Oh and also. Don't do like I did and buy the Steeda Billet CMCV thinking .70" bigger than OEM will benefit more. When I was installing mine, I noticed that, indeed, they are bigger, but the manifold runners are still OEM size and so are the... hole thingies leading to the cylinder. So in essence, I think I added an extra "chamber" for the air to pass through before getting to the cylinder, possibly causing turbulence. Unless you are planing on boring out the manifold runners and your engine block, you won't gain any more than with the OEM CMCV replacements.

I installed the FRPP CMCR plates (when they were around) and I did feel a bit of difference however nothing major, the dyno numbers are 6RWHP across the RPM range so a bit of a snap is good. As for the "bigger" bore plates if you had the C&L manifold and a centrifugal blower then it would be worth it.

define 'feeling a difference', on some misty mornings, not too cold, kinda rainy out.. I notice that throttle sensitivity is increased and the car feels noticably faster. Nothing crazy but it's just faster.

Is it like that kind of feeling? if so then I'll grab some delete plates lol..

wait when you get the C&L manifold I thought the delete plates dont go back on , that they are built onto the manifold

^^
you have the C&L manifold??

stealth_GT · 06-02-2009, 03:41 AM

how hard ( or easy ) is it to remove the intake manifold??

I might pick some delete plates up if I am able to install them myself...

It's not exceedingly hard. It helped that I had a lot of tools at my disposal (thanks to my dad's).

I remember hitting a snag when trying to pull one of the vacuum hose off the side of the manifold. Had to use a small screwdriver to wedge inside that damned hose while yanking it. Disconnecting the sensor plugs was also kind of intimidating since I've never seen that type before. (Just pull back the red lock thingy, press the sides, and yank away)

And the two bolts that are hidden between the manifold runners; I anticipated any problems with Tacobill's instructions and just added some soft clay to the inside of the torque wrench to the bolt wouldn't fall off while taking it out or putting it back in.

I never separated the injectors from the fuel line, I just left them hanging from the side while I worked on the manifold... not recommended, but I didn't have the special tool to clamp the fuel line, and I sure as hell wasn't gonna risk the damage. They were never in the way of the installation.

And I took out the electrical motor that controlled the OEM valves. I looked kind of difficult to separate the valves off that thing, so out the whole thing went. (why keep something non-functional in your engine anyway? warranty work? Better to keep it stored safely away from the dust and engine heat, I say)

And well...just follow TB's instructions and you'll be fine.

once i hit 3k rmp and higher it revs up faster. In conjunction with a tune it did wonders i think.

I remember that when I installed mine, it was a pain!

Did you torque the manifold bolts to specs when you were done?
I didn't since I didn't have a torque wrench.
Two years later, I have no problems. *knocks on wood*. I just followed the pattern.

I did feel an increase in the pull after 3k rpm, nothing major though.

Yeah I used a torque wrench, but now you've made me realize I may have used the wrong torque setting.
TacoBill's tutorial says to use 89 lb-in of torque. I remember reading somewhere that one guy snapped a bolt because he set his wrench to 89 lb-ft of torque and kept going.

I set mine at 14 lb-ft, but I recalculated 89 lb-in = 7.4 lb-ft; so I may have used twice the torque recommended. Damn, I feel stupid. Oh well, nothing snapped.

I think I'll just revisit my parents this weekend and retorque all bolts to the proper specs.
