Well.. I changed mine out last night... haven't had a chance to check it out in depth.. but during my commute this morning... it seems to pull smoother.. not so much that it pulls BETTER than before.. just a lot smoother on acceleration.. no so explosive and without all the intake drama of the z-tube (noise).. it still has a slight growl to it.. but i think that's more due to the MD spacer, AMS drop-in and rev-up air box mods.. ALL of which were done AFTER the z-tube mod (first official mod for me as a G owner!).. as a someone else had mentioned earlier.. all the other stuff was installed after the z-tube, so no way to really tell how the G-tube would have responded to all the mods.. but if you want to get more noise when you accelerate.. the z-tube will give you that.

Like Tony stated before, the dyno showed no HP change between the G-tube vs. the Z-tube.. but rather more so for aesthetics.. it just sounds ballsier!

I'll take his setup through the paces over the upcoming weekend and see how the ECU settles in and how this thing adjusts. I kinda like the whoosh of acceleration without all the noise.. you just feel it as you get pushed back into your seat without getting distracted by all of the noise of the intake system... I'd rather hear the exhaust bark out that sweet VQ35 harmony on accelleration..!!

more on this later...

nice find DB.. once again bro!

 

Good to hear some solid proof other than 'butt dyno' hypothesizing.

 

in for later

 

+1 on the ear plug test

 

snake oil, all in your head, cant make a difference... and Tony from Motordyne says there's no difference.

Sound familiar Dave?

 

isnt a dyno with the car not moving worthless when trying to determine horsepower gains from a "air" intake?

 

Don't really care about what Tony saw on his dyno. I don't doubt his findings at all, but I like the way the car drives with the G-tube back on. We'll see how it does at the strip with this setup. Still need to grab some MAF voltage readings.

 

well, I could be like you and debate this for another 2 weeks by telling you and everyone else that it simply doesn’t work and you’re pushing “snake oil”... but I wont because as you know, I have experienced the same type of thing with the tbs... I think you finally understand why I keep telling you to try it before you dismiss it.

*This isn’t to say that Tony's findings and opinions aren’t valid - I value Tony's expertise and opinions immensely... this is more about the concept of experiencing a mod before stating facts and opinion about it (which you have done to no end Dave).

 

there is still air being drawn on a dyno (car wont run without it ) and many shops (Church's for example) have huge fans that move air at 70 mph... so even though its not the exact conditions of driving, it is a valid method of determine hp and trq... however, as has been noted in a few other instances - its not the say all end all in every case.

 

First off, aren't I your ignore list? Secondly, how am I "pushing" anything? I have made no power gain claims. Please read my first post, slowly, carefully, and with an open mind. No where did I say it was obvious there was a power gain. I'm not making wild claims or misguided science like your spinning air ideas. All I stated was the difference in how my car drove and I posed some questions or ideas about why the car might be driving differently. Additionally, I posed the question that the many resonators on the G-tube and in the airbox might possibly help midrange power (not peak). Read: possibily does not mean definately. Clearly this isn't the case since Tony has compared the G and Z-tubes on the dyno. Regardless, there is a difference in the way the car drives even though the power apparently is the same. Two other owners are experiencing many of the same driveability differences as myself.

Your intentions are obvious, as they've always been over the past couple of years: Come into my threads and stir it up, somehow convincing yourself it what I do to others on this site. I think your assumptions are misguided and you're the one that comes off looking like the jerk. Maybe you should try to turn that "DaveB" ignore function back on if you can't debate in a civil manner?

 

Are you out of your mind??????

My ENTIRE point was that you ALWAYS debate tbs – and you have NEVER used the one that I have commented on… I couldn’t care less about your threads and don’t go into them to “stir it up”… I was being entirely “civil” by trying to get you to finally see that your misguided and inexperienced opinion about the tbs I use isn’t warranted… because you are experiencing something very similar with your G-tube findings…

It’s real simple… I should have just come in here and said you’re wacked and the G tube vs Z-tube is bogus (the same way you do about the tbs)…

You have claimed other cannibal mods too that others have tried and some have reported zero benefit from… I don’t bother to say anything… in this case it was so similar to what you have pooo poo’d that I felt compelled to show you the similarities… unfortunately you are too delusional to get it.

Carry on – put your entire car back to stock, because you still haven’t figured out a way to make it fast enough to be competitive (no matter how much you try to convince yourself and others).

 

I guess the advice you take from Tony is selective. He said as much about the TBS.


Not sure what your contention is here. Dave made no hp gains (as you did) and he did try it before commenting. (G tube).

When I put my Z tube on, I saw no gain/loss (other than noise). IMHO, I'd see a similar effect by putting the G tube back on. (other than noise reduction). Interesting theory though.

 

On all points you attempted to make.

 

I'm trying to figure out when Dave ever said he wanted to make his car competitive? You ever say that Dave? Hell, did you even imply that?

 

In subliminal code, I wrote in my first post that my G is fastest 1st gen car on the site. OCG35 could read the code because we have that connection. Sorry you couldn't pick up on it. Try harder next time. Free your mind and you too will be able to decipher the code. Sorry I can't elaborate on it anymore than that, but I need to go cannibilze some more Nissans.
