my diffuser

I dont care what the other idiots are saying. This happened, pics or not. Sorry this happened before smart phones and selfie location tags. Eat it. Anybody put weight in the trunk for traction? Thats what it felt like, sturdy and stiff, nasty and dirty, made in a barn, out of barn parts. Think twister meets the punisher. I only bring it up again because i'm going to build another one soon, so watch it! i figured i could be scientific about the process, from development to application. Would you guys trash the post if i actually went through the trouble of sharing my results? What i'm really talking about is a dynamic overhaul of the aerodynamics of the car, intake to exhaust. lets talk about tightening those body panels and bolting down what used to be just plastic clips and give these cobra nerds a run for thier money. Bring back the old rivalry already, anybody could buy some bolt ons but the truly greats pushed the limits and squeezed every ounce out of what they had. What do you guys think?

Re: my diffuser

I'm confused, is this some sort of joke? Or are you being serious?

Re: my diffuser

Maybe a little of both. If you read through the other topic i postes on this a few months back you would see how it turned into ice man and maverick grudge match of prove it braugh. Little actual content contributed by these trolls.

Re: my diffuser

Look this is a really long story so ill break it down like this:1. i built a diffuser for a camaro. 2. It was super badass. 3. haters gona hate. 4. Im making another one, and have rescued a 92z in order to accomplish this. First night i took it out this 201? Mustang acted like he was gona race me in my beat up bucket of bolts, and didnt notice me sticking right next to him and chickened out with his $xx,000 car. prolly just messing with me, but it got me thinking about this stuff again. the fab boards are always seeming kinda sparse these days and i just wanted to share what i had to offer i guess. On the other thread i got blasted by forum trolls. they totally shut me down and i never got over it. Just wanted to say im sticking to my schtick here.

Re: my diffuser

I saw that on your other forum. Seems any online forum had guys that are going to knock it, for whatever reason. Build one, it's not going to lift your car off the ground and cause you to fly over a wal-mart. I'm all about pioneering fab work... And pictures would be cool!

Re: my diffuser

Ok, so I'm finally got a driving camaro, and can resume work. Here is an idea of what I'm working with and a mockup of a semi-final paint job. The idea is Nasa type thing.

Re: my diffuser

No, just a little decency from these supposed "enthusiasts". I wanted to conduct a little public research into different types of airflow management and I got lambasted. It was just very discouraging to see my hard work get that kind of treatment. So, what, do you guys get off on criticizing random strangers trying to post their results? I'm sorry but this isn't a magazine. You might actually have to read a little if you want to learn something.

Re: my diffuser

Do you get off on putting yourself in positions that get you lambasted? You made some outrageous claims, that people with decent amounts of experience started to question you on, and you floundered. Couple that with ZERO evidence that you actually built anything worth while, and that's what you get.

Sorry dude... I hate that you got flamed up like that. I really do, because Ive been on these forums for a long time and I love them...and I like to think we're a good community. But..this is the internet. Plenty of enthusiasts here would love to see you work, and discuss it, and come up with different solutions to problems you encounter. But all you have is stories and talk right now. DO SOME WORK! Build it. Post pictures of it. If its good stuff, TRUST ME, those guys will come in and change their tune. If its total crap...well, sorry to say you probably wont get a good response. But at least you'll have something to show.

Anyone that comes onto a forum, makes a claim about something they built or did, and offers no proof or pics or anything is just ASKING for it. Where do you think "PICS OR GTFO" came from?

I was on your side for a bit. But you just made another thread...fishing for trouble. We don't mind reading to "learn something"...but you have to have substantial info for us to read. Not just hearsay and blah blah. I bet if you posted a pic of your diffuser, and it wasn't just cobbled together junk (giving you the benefit of the doubt here), everyone would pay attention and read everything.

Re: my diffuser

You really put a lot of thought into this. I didn't even read half of it. The point is, I made no such ridiculous claims, just that I built something and it might've helped handling a little. The reason I posted was to see if anyone else had experiences with this type of thing, but obviously none of you do. If you don't have anything positive to add, don't add anything at all.

Re: my diffuser

You could say I'm all wrong and such, but I'm adding something, not taking something away or disrespecting other's work. It's a hypothetical discussion anyway, that in the end, the negative criticism overshadowed the positivity. If I hadn't actually built one before and loved it, I probably would have given up. I wonder how many other ideas got scrapped because of this exact situation. You might want to recheck the mentality here, most people don't have thousands to throw into their car, and the third gens are getting older and harder to find. I'd say if you're trying to maintain the market and interest, you'd give a little more breathing room for interested people trying to make advancements in these areas. Besides some internet forum isn't going to break me anyway. I just wish that people would cut the bs so we can actually do something interesting.

Just a thought.

Re: my diffuser

btw, do you see the little pic that is my avatar? That's a 3d model that I made for this project back when I was deeper into it than I am now. Some time went by and I didn't have a third gen anymore so I lost some of the momentum. I recently acquired one, and wanted to build another and post some results. I've been doing a lot of work getting the car into the shape that I want, and have this planned after I get all the kinks out.

And seriously, you can judge my work, and criticize me all day long, but I don't like the prove it mentality that I'm seeing a lot of. It's discouraging to people simply posting information. They don't have to share anything, and I think they often don't because of this. Trip me up on my words but I'm right here and you all know it.

Re: my diffuser

Besides, who is the child here anyway? Enthusiast guy wants to discuss something he made, or the man children trying to tear it down. I cant believe you all are taking thier side on this. This is the second topic ive posted that got smeared like toilet paper. Who is being childing here?

Rhetorical question. I already know the answer. Besides, i posted this to stir up some discussion while i do other things on the car, and test the market. If you were ever interested in the actual idea, and not just the climb on the maturity totem pole, you wouldnt care how i feel when people smear my topics.

Re: my diffuser

I'm not taking anybody's side. Id like to see what you built. I am a fabricator myself and am a big believer in DIY stuff. So IMO, I wouldn't really care or worry about what people on this site say/do. Hell, who knows, Maybe it will give you the drive to do it! So, close the computer, get out in the garage, and fabricate!

Re: my diffuser

I work on an around race cars everyday which all require many part to be fabricated from the ground up. I've never seen someone get so bent out of shape over a disagreement on design and implementation. You know what I do when someone doesn't like something I did on my personal car? Forget about it five minutes later and move on with my daily life.

Fabrication is not my thing, and even if you fab one, I would have no interest. The ball is in you court, as it has been since you started this thread. You started it. Finish it.

Re: my diffuser

This type of thing has been done before, theres nothing special about this design or that, or even cost of matetials. I just wanted to hear what you guys thought about it. Theres been others, that one guy was building one and it looked damn good. There was an older one also that was in japan i think. Besides, the one i made was on a 4th gen, but like i said i looked and it should bolt right up. Nothing fancy.

After half a dozen people post, i found one post where the guy said he didnt want to see a piece of crap and thats been the only mention of it the whole time.

Re: my diffuser

I forgot I even posted that...thats how much thought Ive put into it since.

I actually didn't put much thought into it at all. I could care less really...since I have no real use for a diffuser on the street. Your post just annoyed the crap out of me. Red Devil beat me to it haha... Little hypocritical, don't you think?.

You DID make ridiculous claims. I remember... You said it saved your life or some BS. Kept your car from going out of control at basically two lane highway speeds. Lots of people called you out on it. And here you are, now trying to have a serious discussion, claiming you don't have to prove anything. At this point...yes you do. 3D model of a thirdgen? Do you have any calculations attached to the 3D model? Or did you just draw something pretty?

DBLTKE makes a good point...and that's how most of us operate. You, however, seem to like coming back for more. You know how this is going to be received. You like it. Otherwise you'd know better haha.

And since you probably wont read this, you'll never realize that I actually hope you do come up with a good design. That'd be awesome. But you've shown no promise of that. I don't care what you say you've done. Build it... Test it... Post it. Then you'll get real discussion.

J.

EDIT: I was actually afraid maybe I confused you with someone else. So I re-read your original thread. GO back. Read it. Listen to how ridiculous some of it is. Also note my supportive posts, before you derailed yourself and made the thread go downhill. Then...I see you started another thread, titled exactly the same as this one...calling us idiots. Now a third thread. 3. Still with zero good back up for your "discussion". Ugh...That about sums it up.

Re: my diffuser

I reall don't care what you think. Thats the whole point. You can call me crazy all day long but i was there, and i know what it felt like. Besides, if youve ever been in a serious accident and walked away you would be thanking every last little nut and bolt on the car. I believe i said that it helped, or at least could have helped. Something about those little wing shapes resisting side to side air flow, could have slowed it down just a little, could have saved me. Youre on the right track, but if youre so damn determined then prove it wrong using some kind of half way believable scientific sounding words, and not just ridicule me for lack of pictures.

Youre on the right track, but if youre so damn determined then prove it wrong using some kind of half way believable scientific sounding words, and not just ridicule me for lack of pictures.
Hey man, I'm sorry. You lose more and more credibility with each post you put up.

Unsubscibed.

Re: my diffuser

You don't care? Then leave! Youve got nothing invested into this, no reason to waste your time. If the evidence was staring you in the face you wouldn't believe me, so what difference does it make? You think i need subscruptions from people like you? I dont, and the sad part about it is that you some how believe that youre going to hurt my feelings or shame me into submitting to your will. Thats the whole reason i made this topic.

I did this on my own, and didnt have to take pictures or prove anything to anyone. That wasn't the point. I did this because i believed in the science behind it. If you don't care about any of that stuff quit clogging up my posts with your bs.

Re: my diffuser

Oh, and for the jab at my credibility, this is the internet, and at thr current moment, this js a hypothetical discussion. I said i made one for the 4th gen, and that it would bolt up. As far as youre concerned, theres no reason to trust one idea over the other because ideas must be tested to determine thier legitimacy.

I'm going to post up a few pics in a little bit you can pick and stab at all night long if you wish. Like i said the whole point was that you were more concerned about tearing it down, and damaging credibility, criticizing grammar, and petty things like that. Those posts have absoultely no bearing on the topic or the discussion.

Re: my diffuser

There is no topic or discussion... You got all defensive when people questioned your project. That just opened the flood gates for people to peck at you.

No..if the evidence was staring us in the face, we'd have no choice but to believe you. But...there's nothing. A thumbnail pic of a drawing you did and a bunch of

You made this topic to stir up drama. Good job! It worked! If you started it for any other reason, you would have come into it having learned from the last one.

And Im sorry to say, its impossible to clog these threads with anymore BS. They were cursed from the start when you called people idiots and picked up right where you left off.

Im gonna leave you alone now. According to you, you dont need people like me subscribing, so I know it wont bother you any. Its kind of fun. Because of your responses...but I get bored quick. Good luck with your car though! Look forward to seeing a post with progress at some point!

Re: my diffuser

What? A man cant stick up for himself? I start making ground in my argument and suddenly its time for you to sail away into a golden sunset of rational superiority. Be my guest.

Re: my diffuser

Ok...Ill stay. Only because your responses are becoming almost poetic. "...golden sunset of rational superiority." I like it.

What ground have you made?

You can ABSOLUTELY stick up for yourself. But at this point, the only way you can do that is...well I dont want to beat the dead horse. Also, sticking up for yourself when being attacked for no reason is one thing. Provoking trouble, then retorting, is not sticking up for yourself.

P.S... Im really curious (not being smart). What did you use to make your 3D model of the camaro? Do you still have the file? That could actually prove to be more of a discussion topic than the diffuser at this point haha.

Re: my diffuser

So this one time, I made a diffuser too, and my car was like so totally fast and aerodynamic. It would do 900G's. I would show it to you but my cat ate the pictures. But it was like totally real! I was driving so fast one time it caused my car to break the space-time continuum and I ended up in another dimension. I think I even passed Marty McFly and Doc Brown along the way. I'd take some more pictures of my diffuser, but the car is still stuck in the other dimension.

This is what it's like listening to you drone on about your magical invisible diffuser...

In this picture you can clearly see the same diffuser on Mermaidman's boatmobile!

Re: my diffuser


Trust me, my plan was just to stir up some discussion on the matter while I do my engine swap. Once that's done, I'll spend some serious time on this.

Re: my diffuser

Look I know you guys like pics but I got to do this stuff so here it goes. And there are pics.

Look at Fig. 1:

Notice how the 4th gen is a sleek and slender type of car. If the car was to turn sideways, this is what the air could see coming at it. When you increase the percentage of side profile air flow, the car would be, even slightly, more resistant to side to side type of airflow.

Now look at fig 2 a&b:

In Fig. 2b, the lower one, the one with the box, you see how rigid flat surfaces resist smooth airflow. Smooth airflow = higher speed. Rigid airflow generates turbulence and thus slows the vehicle down.

In fig 2a, the one with the sedan looking car, look at the amount of contrast between the high and low pressure zones. While this might not be the most scientific example, it's obvious that there are big differences and pretty colors.

In Fig 3. we see the formula looking car, notice how the smooth edges generate less color contrast than in the last picture. The point is that these smooth edges and subtle contrasts give the car an aerodynamic advantage when it comes to forward movement, meaning it can go faster because it's smoother.

Fig 4 is another example of this. I'm sure all of you know what those little wingy things are so no need for me to tell you. They work the same way, but they are at their most effective if the car is going mostly backwards, or has at least spun around once.

So, looking back at fig 1 you see the yellow line representing the average lowest part of the body, and pink representing where this diffuser would be. It's obvious that even if the diffuser represents a single digit percentage of the side profile of the vehicle, along with the fact that it's channeled and has multiple little wings, it could still help slow the vehicle down in a spin-out type of scenario, even if it's just a little bit.

If you've ever been in a serious accident before you know how those little percentages can add up. Real fast. I'm suggesting further work into these ideas. I wanted to create an entire bottom pan for the whole car, complete with front spoiler, a full air tract along the bottom of the car, as well as a heavy diffuser with exhaust ports. I aim to not only prove my theory correct, but to blow your expectations out of the water with my simple concepts and suave vocabulary.

Re: my diffuser

OK, it's a start, sorta. Now, lets incorpoate all that scientific data and generate a depiction of a 3rd gen diffuser.

Here's a start...I have this on my GTA.....NOT!
