Very nice design. Looks great.

What's the availability of the rubber o-ring? Is that a custom o-ring that you're selling with the unit or is it a readily available size at any auto parts store?

The "O" rings are 1/8" width and 3 1/2" ID viton O-rings. They are available online and most likely in some hardware stores. Not all O-rings are equal. The ones I choose have a temperature rating of -10 thru +400 deg F. and are ethanol compatible.

PERFORMANCE GAINS:

The original rubber fitting between the metering plate and the butterfly valve assembly is NLA. There is also a performance aspect to this part. The new plate has a larger inside diameter and matches the inside profile of the air intake system, increasing air flow!

3676736777


This diagram demonstrates how the profile of the original rubber gasket chokes the air intake system. Air from the metering plate hits the side walls of the original part and creates turbulence.

My new plate eliminates any restriction of air flow and allows it to go straight through. This is especially beneficial if you have a performance air filter and cold air intake system!


The images below shows the original gasket and the new plate to show the difference.

The original opening is increased in area by 33%!

Just out of curiosity, have you tested this in a wind tunnel or conducted a fluid dynamics test?

The reason I ask is because, while your hypothesis of an increased air flow due to the more "open" nature of your piece seems sound, I think you are discounting the Venturi Effect which states that fluids - in this case air flow which acts as a fluid - speeds up when the aperture narrows.

Also I have to wonder what role Bernoulli's Principle plays in the shape of the factory issued rubber gasket. Being rounded like an air foil, does it actually increase airflow through the throttle housing?

Of course, all of this is speculative on my part and doesn't mean your claims are not accurate. I just think you might want to conduct some comparison testing to determine if what you claim is verifiable. If your idea holds up to testing than you have even more data to potentially increase sales.

I love the machining on your design. I'm not really into performance upgrades but if I was still employed I would definitely buy one. I may decide to buy one anyway.

[FABombjoy]

I received mine yesterday. Overall a very impressive product and packaging! The instructions are well-written and very thorough. Really looking forward to future projects :)

"Just out of curiosity, have you tested this in a wind tunnel or conducted a fluid dynamics test?"


Nope, no tests or anything formal..... I spilled some coffee on it once and it cleaned up nice!

Look, I just do this for fun. I love getting things in the mail for my Delorean. It gives me a reason to get out of the house and tinker on my car. Now I get to share that with others too!

I'm sure somebody someday may do some tests. But the main thing is that this is a brand new part in the world of Deloreans. Test it, install it on you car, talk about it. How fun is that!

BTW I'm not done with the throttle assembly. More is yet to come.

For certain, Gary. If nothing else you've provided a viable replacement for an no longer available part.
Good on ya' for that!

I agree with you on the testing. Computational fluid dynamics is very difficult to analyze without testing. Closed channel flow is a little easier than open channel flow, but still, there are a lot of factors to consider.

That being said, I also agree that this is a very nice replacement part to an otherwise unavailable part. Whether or not there is any performance gain, or even loss, is really secondary to the fact that now there is an option for replacement/repair, when before an option did not exist. :thumbup:

Gary,

You say your o-rings are Viton. This is interesting since the only Viton o-rings I'm familiar with were a brown material. Yours are Black, which would lead me to believe they are just standard Buna N (nitrile) O-rings. Which has a -35 to 250F rating.

Not that it really matters, I'm sure that's all that the rubber gasket was.

Where did you get the O-rings from? All I'm getting at is that I've never knowingly seen or used black Viton O-rings before.

My PPR o-rings are black viton.

Easy to test if viton by soaking in E10 fuel. Viton will not expand and Buna will.

[Nicholas R]

My PPR o-rings are black viton.


I too have purchased black viton o-rings many times.

Is that color coding an industry standard or someting? I spec out o-rings from Parker Hannifin a lot at work and haven't seen this intricate color coding before. I've gotten a lot of different materials in black, once got brown, and once got grey. Couldn't tell you what they all were though. The material is usually based on the fluid they're interacting with and sealing. Its usually based on a Parker material spreadsheet, or their o-ring tech support.

I remember that the brown ones I got were specifically for sealing DOT 3 brake fluid (for a Disney vehicle :wink:). They were Perfluoroelastomer (had to re-look that one up) o-rings, and I remember being surprised that they were brown.

EDIT: This is my go-to for o-rings. The Parker O-Ring handbook. They sent me a hard copy a while back. I honestly had no idea there was such a serious science to o-rings but it is major. Thats why they have an entire support department dedicated to just helping to get you the exact o-rings you need.

My original post has the wrong paypal email address. Go figure, I ask you for a correct shipping address and I have a messed up e-mail address.

the right one is [email protected]

Sorry for that!

PM me if you have tried using the one with the "L" missing on the end of my name.

I received my intake spacer today, and I have to say, "wow!" Upon opening the package, I was instantly greeted with the quality plate and instructions. I am very happy with your product!

[Gary]

It looks like I have been under cut by DPI. I'll have to lower the price (please PM me). I have 30 left. Anybody who bought the original 9 can request a refund of the difference.

So please PM me for current pricing and shipping.

If you really believe in your product, that doesn't mean you have to drop your price (especially to the point that you're loosing money). The products you're selling are very different. Theirs is a replica of the original, where yours is a modified (potentially) upgraded product.

I doubt that everyone that bought one of yours was in need of a replacement part. They were likely more interested in it given it's obvious differences compared to an original.

You are not making the same part. A small price drop could be justified now that there is another option available, but you certainly shouldn't force yourself to loose money on this project.

My 2 cents, but I'm sure some others would agree. :thumbup:

[FABombjoy]

Agreed! You have a quality product and good customer service. There is no need to race to the bottom on price.

I agree with Nick... This is not an apple to apples comparison.
You're not selling the same apples as Josh. He is selling a repro of the original design. You're offering a different made part. It stands to reason the manufacturing process and materials are going to cost more therefore the part will cost more. It's up to people to decide which they want to buy with their money.

I just looked at the DPI offering as a comparison. Only $49.95, FWIW. The product description also addresses the performance questions.

[Gary]

Thanks guys! That means a lot to me. I am going to evaluate the situation for a while and see. DPI need not worry about me. I am not planning on going into the parts business. I like to create elegant and useful things. I am a residential architect by trade.

[DMC5180]

Gary,

I put 400 mi on your design today. No issues as expected.

[FABombjoy]

It was $59.95 a week ago.

[Iznodmad]

And now it is listed for a completely different price. Hmmmm. Too bad I didn't get a screen shot. Oh well.

[Nicholas R]

The website says the part is $110.

Wtf! I looked last night and it said, $49.95

Personally, I much prefer the dual O-ring seal that Gary incorporated. If they ever need replacing it can be done for a few dollars.

Speaking of O-ring, what is the nominal size? Should they need replacing years from now.

Now the DPI one is "call for pricing" :)

[Delorean Industries]

Come on guys... Lighten up and have some fun. :)

[Gary]

Fun?! Do you think screwing around with my project that I worked very hard fun? You copy it and attempt to run to market with it first. Then you jack around with the pricing, forcing me to react.

The other forum members have been very supportive, they represent the best of this community. You on the other hand well, I was shocked that a vendor would run his business like this.



I never mentioned that the machinist that I have worked with on this project was an attorney who dealt in matters like this. Who by the way, is now ticked off.

Careful who you have "Fun with"

Gary

[Delorean Industries]

I thought I was done having fun. Apparently not. Stop teasing me and prove my development testing wrong. How do you even know we haven't been using these for years on our cars due to nos failures but not advertising? I'm hearing a whole lot of unsubstantiated crying, unwarranted price dropping on your part and a general woe is me tone. I think a few people set you straight right off the bat. Completely different design, material and interpretation of the oem concept. While manipulating pricing seems unfair due to our manufacturing power house it doesn't break any rules. It is completely legal even in a business to business market place. Especially one where I can make my own rules.

FYI I didn't start playing with the price for fun until you went off the deep end and dropped yours. My cost is 3.37 per unit and I made 100 originally and have worked through the batch since. Everyone that placed an order up to this point received it for 8.47 shipped. I have 14 left for shop use now thanks to my inventory being set to switch over to call for pricing when the threshold is met. Just saying you literally drove the sale of these at whole sale price with discount at check out after posting here and else where that we "under cut" you. Depending on how you look at it you did this to yourself. I made no effort to market our option here.


Free advice: attorney turned machinist usually not a good sign.

[Gary]

I'm sorry Josh.

Gary

[Gary]

I have messed this up on so many levels.

First thing, Josh is right. I am the one that flew off the deep end. He choose to market his product else where, not here on the forum, where he has more right to post here than I do. His product is different than mine. Others have tried to tell me this. Then I used the encouragement of the other forum members to try and use against DPI. Then, if that was not enough, I made a desperate and hollow threat against DPI. I never thought I was capable of such selfishness. I am shocked at myself and I apologize to everyone who encouraged and supported me in the past.

I am sorry Josh, to your company DPI and (if you can believe this) I thank you for throwing a big cold bucket of water on me to wake me up.

Gary

[Delorean Industries]

Gary,
You have not messed this up on so many levels. Your response was on par with someone that has time and materials invested in something. While my response at length was full of valid points I presented it rather aggressively when I really didn't need to. I should have consulted you privately earlier on instead of letting it play out as it did. It is wrong of me to take that approach with things and whole sale products just to do it. Kinda defeats the purpose of having a business. But I digress...

With that said I would recommend the following: Maintain your original or close there to price point as before and continue to market regardless of what others offer. There will always be others with something like it or copying. Crappy part about the world we live in. Just put yourself above it when ever possible.

In regards to your current inventory. Contact me privately on this and we can discuss assisting in selling to our customer base and other marketing avenues. I provided details on testing and application use and this is valid on cars with certain modifications that we specialize in. Once the batch is sold through and you recoup your costs we can discuss continuing to assist with selling a future batch through your supplier or provide a cost analysis comparison against our cnc services to streamline if possible. (we are bringing multiple Hass tool rooms in house currently)

Btw.... No hard feelings on the attack. No apology necessary.

Regards Josh

[Delorean Industries]

@ Dennis: Not feeling this rabbit hole?

[DMC5180]

Well Josh, I'm certainly pleased you crawled out of that hole and cleared the air with Gary. It's almost a love fest of mutual respect now.

Unfortunately, when you started screwing with your pricing. It came across somewhat mean spirited rather than you having fun. Now, had you posted jokingly "One Milllliiion Dollars!" We would have obviously known you were just having fun.

I guess it just comes down to perception.

Anyway, I'm glad you cleared things up.
