Z1 smooth tubes worth it?

ImportConvert · 03-01-2012, 08:13 PM

Is it worth it to try to cram 10 pounds of crap in the 3 pound bag that is the distance between the airbox and the TB? How the F*CK does this part even fit? No room.

I am assuming that you are referring to the Z1 silicone post Maf tubes! I have never seen a set myself in person but the concept is real simple and makes sense. By ditching the slinky style stock post Maf tube and going to a smooth tube you will decrease air turbulence. Anytime you can do this you will increase velocity. Now in the case of this car in N/A form the gains would be very minimal. Personally I would need to see a dyno chart comparison to believe there would be any gains.

However, if it was my car, for the minimal cost, I would probably invest the money in them for peace of mind!

Thanks, Tony

Been there, done that. They were worth it to me. I'm not sure about the HP gains

For the money, yes.

That + K&N (or other high flow panel filters) gets you within 5 +2 whp or so of the pricier G3's.

Some wrestling is required, but it will all fit.

Okay, now that it's installed, it's worth it. I don't know if it gave me anything, but it looks nice and in theory it gave me something. It was hell installing.

It is a bit tricky. I pulled the stock airboxs out and removed the strut brace to get more room.

I have mishimoto MAF tubes and k&n drop-ins. I isntalled them together. I def. feel gains in 1st, 2nd, and 3rd, but not as much in 4th to 6th. Then again, with only 800 miles on my car, I limit how many times I go WOT to redline.

I did this and STILL couldn't get them in! They don't even seem close to me. If I attached them to the airbox and tried to slip it back in, the duct on it was a good 1/2" from clearing the front fascia. Any ideas or tips? I wrestled with one for an hour before giving up. Here's a photo. I don't see how it could ever fit.

IMO, they're worth it. I bought hoping they would add a little HP on the topend of the powerband (which helps a ton if you raise your revlimiter).

No dyno result but I do have some track results:
I gained a little more than 1mph in the 1/4 mile after adding 2-piece front rotors and post MAF tubes. This was in similar temperatures/DA on the same track, several runs for each night.

Which mod made the most difference? who knows.

I did dyno comparison and I saw Zero gains over stock using the K&N filters and post Maf tubes.

Maybe others have had better luck then I did with this setup.

LakeShow · 03-15-2012, 02:15 AM

I think it's something you feel as the responsiveness of the car rather than numbers on paper or computer.

I got mine installed. I removed the air-boxes and attached them first to the TB, then got sex nuts and retard strong on it. I forced it to work. Then re-installed the air-boxes. (I kept them CLOSE to in location while attaching).

Other mods to the car? Dyno chart please?

Did you remove the negative battery terminal and reset the ECU? Or get a tune afterwards?

The ECU bases WOT response on closed loop look-up tables + MAF input in every other car I have owned. This wouldn't effect that.

Even if it did, after a certain number of key on/off engine on/off cycles, it should adapt, no?
