[/QUOTE] This is an open forum and I am entitled to state my opinion.
The majority of the forum is new to swapping manifolds and could be perceived as impressionable.

:iagree:

 

I will readily grant you that some tunnel ram intakes may have been converted to EFI with custom plenums that used TPI style throttle bodies, before I built the first modified stealth ram plenum.

(1) BUT , having seen that EFI modified tunnel ram intake in the picture above for the VERY first time today, I could hardly have copied it almost a year ago!

(2)the picture looks like nice work!

(3) you may not be aware that the stealth ram only came out about a year ago, NOT several years ago like your claiming so I obviously did not and could not have copied any stealth ram modification untill it existed.

(4) I have also made modified SY1 CARB intake to EFI mods and CROWER fuel injection intake mods, and converted crower constant flow to EFI injection

(5) since the TPI throttle body and basic HOLLEY EFI intake plus the corvette hood line only allow certain mods to fit and function its not that unusual that most solutions will tend to have some similar design features to allow the linkage, ETC. to fit and function

(6) all internal bracing, connection locations and air flow design on the http://www.fasterdeals.com/garageindex.html
are extremely similar to HOLLEYS orriginal design,
so almost every internal and external feature EXCEPT total height,and VACUME port locations and distributor clearance are similar, and those modifications were made for greater ease of installation or clearance, the main differance is only lower height and easier installation. BUT the differance is enought to allow the custom intake to fit and function in a TPI corvette

The manifold I posted has been around for years and has modifications that make it work. The box you sell and the better one do not have what it takes to work properly. I guess you missed that part of my post. The better plenum has a chance to be corrected if someone does real testing. The one you sell will be a paper weight when the fix is discovered.


Reread the post above. I said that the manifold that I posted was made several years ago.

If this is true, and I am suspect, what does it have to do with this topic? I still want to see ANY verification to the claims about your testing. I doubt there are any. The testing that I have seen posted with out substantiation is erroneous. The opinion I have formed is that you made a box and put it on you car it worked as far as your abilities could tell. A few people are drawn in buying a flawed plenum by the hype and if they get to have it tuned by someone with experience the flaws will surface.

 

its obvious you don,t want to deal in anything BUT slandering a good product and only based on YOUR opinions,and want to argue, have fun,(by yourself) its obvious at least to me that you for some reason want to start a pissing contest, as this does neither the corvette forum or anyone on it any service, I refuse to participate further in what is only YOUR mis- guided opinion.
IM here to HELP other corvette owners, I have not made any profit yet and built a limited run of custom plenums soley to help other corvette owners, and allow them to use the stealth ram , I don,t know what your problem is, but have a great life!

I am responding to your request. Sorry you don't like the facts. When you make false accusations of accusing me of working for someone I never meet and want facts, be sure you have your ducks in a row before you call me out.

I have no vested interest in anything other than being sure that people are not fooled into something I know doesn’t work. If you feel differently please post your documented results. Needless to say you’re here for the potential to profit off the sale.

 

Guys,

I think both make good points and in my mind, yes the Jury is still out on the Stealthram as Blownvette has aptly pointed out. But, on the flip side, I give a big thumbs up to people such as Grumpyvette who is attempting to develop and refine a product for TPI motors.... which as a lot of you know, has taken a big backseat to the newer generation LS-1 by the engine product developers & tuners. Regardless of if the final outcome is good or bad with the Stealthram.... I give Grumpy a thumbs up for the effort.

My suggestion... lets just sit back and wait and see the results of this intake as more people try it.

cheers,
Beach Bum

 

:iagree:
Blown Vette lighten up will ya? :crazy:

 

Please let me know how you can give a recommendation on something you are going to try this winter?

If you understood what I posted you should be thanking me for the warning about the flawed box. I have a lot more information that will be given on this subject. Currently I am still waiting for a post that contains any substantiation to the supposed testing.

 

Why dont you post the information you feel indicates that the other plenums are flawed. This way all the info is available for everyone to read and people can decide whether they want to spend their money accordingly.

 

Well post your info on why this is such a flawed box? You've been putting this design down since it was introduced...........why? Have you tested this intake yourself? If so we would love to see your data.
Please let us know..........were all waiting.

 

We're still waiting for a post from you that gives any sort of substantiation to your claims. So far, none! You have not posted one thing that gives you the credibility you seek. Just another mudslinger with no facts or numbers to back up your arguement.

 

its a physical impossiability to have any data on parts youve never even seen, or tested and if you think that data presented by someone with the obvious goal of making something look bad is valid then its hopeless.
only independent dyno results by someone with no agenda will be valid and even then the part being tested must match the rest of combo being tested,to bring out the best results, any one can make any part look good or bad by carefully matching or mis-matching the total parts in a test.
below youll see a few dyno tests compareing the ported TPI,miniram and stealth ram, their will be almost ZERO differance between the standard stealth ram plenum in the testing and the custom plenum, in spite of what SOME individuals with no data are sure to say.
there will be independent data shortly on the custom stealth ram as several individuals are now running and testing it on their cars , and the average results will show what does and does not tend to work well
in the mean time heres independent data on the standard stealth ram vs other intake manifolds

The picture I have posted is a manifold that was made many years ago from a carb tunnel ram that was converted. The problems were discovered and addressed. I am not here selling a product and those that have e-mailed me for information on the fix or to purchase a plenum are not going to be answered.

If you want to buy something based on a seller telling you it is great, that is your choice. When I see a better option and am falsely accused of working for someone and attacked for my opinion on an open forum I will defend myself and start the process to expose the flaws. I doubt many of the posters have much experience with fabricated parts as a quick check of the listed mods of those replying on this thread think a mod worth mentioning is a gutted CAT and a K&N filter. Just the same they are just the type that are impressionable enough to be influenced by hype

[B]If you notice in the posts made by the vendor selling the black box you will notice when ever he makes a statement and someone asks for more information there is no reply or a cut and paste of someone else’s work on a factory produced manifold. There is a difference and as I stated above if it is ever tuned by someone with experience the flaws will surface. My view is that there is a better choice that the painted box.

The opinion I want to get across is:

1) The black box is a copy of what we did about five years ago. We found a problem and the fix is not in either plenum.

2) The seller of the black box makes claims that it is a proven piece and it is not. The reply above is a case and point.

3) The seller uses information of a factory piece to represent his product. They are different and if someone that knows what they are doing ever tests it the design won’t be able to be repaired. The other one will be able to be fixed.

 

WHAT WAS THE PROBLEM? :crazy:

 

You keep saying problem problem problem...yet you dont mention what the problem is. As is stands it sounds like you are simply bashing someone elses work and don't have a clue what the heck you are talking about. If you want someone to take you seriously then make a serious post. State what the problem is, how it will effect performance, how it could be fixed in the "other plenum", and why it could not be fixed in the "black box". If you dont know the answers to these or are not willing to share them with the impressionable public stop being a :troll .

 

:withstupid: :lurk:

 

so what you're getting at is the Holley design is inherently flawed to begin with? Grumpy has just re-designed the plenum to clear the low-rise corvette hood, where is the design flaw? as it is almost identical to the SR plenum sold by holley. Please do share the problem with us.

 

I say some people here (grumpyvette) should step up and send the HSR to Jesse while he is doing the intake testing so we can clear all of this up. If this custom plenum is what grumpyvette says it is, he stands to make alot of money (and you should be a supporting vendor already with the amount of information your spewing about selling this product), especially if it is endorsed by one of the forums more knowledgable members in independent testing.

I will step up and purchase the HSR as is from summit and have it shipped to Jesse, if grumpyvette will provide the plenum and fuel rails. I am sure another forum member has a small base distributor to send to Jesse for a test, if he doesn't have one already.

How about it grumpyvette? You've got nothing to lose by sending your product to Jesse if it works as you have stated. I am willing to spend $300.00 to find out if your plenum works in independent testing.

Step up to the plate and stand behind your product. If there is a flaw in your design I have all the faith in the world that Jesse will find it.

 

I never said that the problem was with Holly’s part, that one has been tested. The untested part is the problem. Look at my post with the converted manifold and you will see that this was done before, long before. Honestly I could care less if anyone buys this guys box or not. I know what my experience was and gave an honest recommendation. I am not here to fix a problem on a product that someone else is trying to profit.

With this list of mods you and the other 20 year old should jump on the black box. Try it and then come back and let me know how I don’t know anything.

 

You do realize you still havent stated what the problem with the 3rd party plenum is, dont you? You just keep saying it's "flawed", fine. Now, "how" is it flawed? "Why" is it flawed? "What" are the negative impacts of the flaw?

I think you can provide these answers without helping the manufacturer of the product.

Examples of how you can explain:

- It is flawed because of the inconsistent air flow to different cylinders due to the restrictions....
- Due to the plenum being redesigned and the flow pattern being altered from the redesign, it flows less....

Examples of BAD explanations:
- This thing is the king of all that sucks because it sucks
- It dont work because it dont work

I dont think we are being unreasonable by asking you to support your claims with facts. Much like how you asked Grumpy to support his claims of his product with facts.
