You come on the board making great claims about how much you can do with duct tape and whatever, but refuse to show anyone any pictures of anything. This is new for us, usually people come to the board wanting to share information, not tease us with tidbits.
Hmmm, seems I mentioned wanting to rid the system of duct tape, not bragging about what I could do with it. Just one of those things. Further, you have seen scanned copies of both dynosheets I have currently. I didn't think I had to provide detailed diagrams, schemetics, and pictures to share information. Infact the only thing I have told you is how to assemble my system.
If you want to pursue the sales of turbochargers, you should contact the board administrators and set up an advertising account.
If you are here to share information, do it.
So far, you've been of no benefit to anyone at all.

So I guess none of the other threads I've offered advice based on my own experiences don't count. I guess none of the people who have emailed me asking for help on their own turbo systems count either. I guess no-one on this board is allowed to exist here unless they post detailed information and specifications backed up with pictures of everything they've done. Sounds like a welcome place to me! However, I'll consider you in the minority based on what I've seen from others here.
Just my opinion

When the MAF sensor maxes your inj pulsewidth cuts in half. It's not a wives tale, it is reality. I've tuned enough forced induction LT1's firsthand to know it.
I still don't think 128 mph with a bone stock LT1 and 11 psi is possible (especially with your fuel system and tuning), but that's just my opinion.
What will pictures prove? If anything, it will prove that you have a 97 camaro with a home-fabricated turbo system. Any pictures at this point would just add some credibility to your claims.

The proof game just goes on till people start asking for a motor tear downs looking for non-stock internals, secret NOS systems or all sorts of crazy stuff. In the end there is a point where you just have to trust that a person is telling the truth, because you will never be able to prove anything past a certain point.
In time you'll trust him or not, it's not a big deal. That goes for anybody in life.

its not like someone is going to copy it just from pics.
every other company out there has pics of their products....thats business.

I not going to comment on the numbers or whether or not I believe the kit is real, but some of what you posted is seems like just talk because you want verification, or want to see pictures. Like the part you say about "every other company out there has of their products pics.... thats business".
Sure, most companies have pictures, but when MANY compaies have something in the prototype stages they dont share pictures either. Until it's READY FOR SALE . That's just commons sense and smart business. I don't know if the guy is telling the truth or not, but showing prototype pictures of something like this if you are going to make business out of is often stupid business, and I'll even say stupid period.
That leads to the next point you make about " it's not like someone is going to copy it just from pics".
Personally I am going to design a kit for peronal use on my daily driver, and maybe weekend car. I don't want to produce any , or sell them, but for someone that did, you can get a great deal of info and design info regerding the turbo header(which is the main part of the whole deal) just by looking at the kit. I know, because the setup I'm making for my cars I got from looking a pictures of setups over the net of guys who WILLINGLY did share their info . I just picked the pictures of the headers i liked. ALL I HAVE TO DO IS DUPLICATE IT!! (Or if you dont weld have a shop or welder do it. For some that might be difficult, but for those with the skills, and mandrel benders, u bends, welder etc. It's not that hard. Someone with decent skills can easially buy bends , or pipe,(if they have a bender) and build a header just from a picture and get it pretty close, or darn near the same. Or just take it to an expert chassis builder or welder who can do it with no problem. QUITE a few Mustang and Fbody guys have done it already.
The guys who's pictures i used don't mine, and they FREELY shared info, but they were not making a business out of it, so they didn't care. It was a free exchange of info. But showing pictures before it's ready can be bad for someone who wants to sell it. So IF the guy is telling the truth about the kit, I AIN'T MAD AT HIM. LOL. Just think about the situation. Now if someone does not show pictures, and they are trying to sell the kit AFTER IT"S READY to sell, and expect to get your money, then that's obsurd, but he said he will have picturs when it's ready. So those who want it will just have to wait. Im not trying to support the guy or his doubters, and I don't mean for this post to semm negative. But if this post is real, I can understand why he didn't give pictures yet. If he is lying about really building it , of course we know why there are no pictures, and if he is telling the truth, then I can understand why he wouldn't show a prototype until it's ready to go on the market.
The # seem high, but i have seen some strange things, so i'll just keep following the story and try not to jump to conclusions. Again this wasn't a negative post. I just can understand the picture issue. (Or lack of pictures)

Give him a freaking break, just b/c you arent smart enough or dont have the resources to do somthing like this doesnt mean that somone else cant. So stop b*tching and whining about somthing that really doesnt effect your day to day life and get on with it, if he has it great (and in all honesty that is about what i would expect from a turboed stock motor, just no one else seems serious enough besides takling about how it cant be done, he went out there and did it.) Efficiency is where its at, seems this is a very efficient setup so it makes the power it should. Personally i would like to say awesome job, its about time somone did what some of us always knew could be done. Anyone who doesnt believe him, fine shouldnt be any skin off his back or anyone elses, you all take this internet thing WAAAAAY to seriously..

Wow, things really livened up! Thanks to all of you who understand and support my reasoning. To those that don't, sorry you can't make the connection.
Whistler - what do you think, maybe I made those dynosheets in Microsoft Paint? Or maybe you never read far enough into any of my posts that you didn't see where I said the A/F ratio was 15:1 on the 484 pull. It didn't blow because I got out of it in a hurry. Hense the numerous references to the "Aborted" dyno pull. I also mentioned that I did the testing on 101 unleaded. Not ever did I say I drive it around everyday making 10lbs of boost on a stock fuel system with stock programming. BUT, adding nothing more than 30lb SVO injectors and race gas, I did run plenty of passes at 10psi plus. I do drive around at 7psi on 93.
INTMD8 - That whole injector pulse thing is amazing isn't it? I guess those 30lb SVO injectors really made a difference since the system is outflowing the maf around 5 psi? The engine should have blown on that 13.5 @ 117mph pass I made, let alone the 11.9 at 128?! This is a classic example of, I've read something somewhere and because it is in print on the internet, it must be true! So.. why is it none of the supercharger guys running 7-8 psi on stock injectors and programming are blowing up? If you stop and think about it, you might find you will ask yourself, "What did GM hope to achive by cutting the injector pulse in 1/2 if the maf goes out of calibration?" Seems to me they would be running a risk of people leaning out and blowing their engines if they did that. That in turn generates warrentee claims that they might not have had to pay. Not a good business practice. I don't know what you seen where that would make you think that but rest assured, on my 1997 OBDII computer with stock programming, it keeps the injector pulse right where it's programmed to.
The question remains to everyone calling BS, "How much money are you willing to put down on a frivilous BS call?"

I dyno tune cars at Speed Inc. with the LT1/LS1 edit software and I have personally seen 4 obd2 forced induction cars that cut injector pulsewidth in half when the maf sensor maxes out.
I'm not saying your engine should have blown. Maybe with the 30lb injectors and FMU you have just enough.
Why are none of the supercharger guys running 7-8 psi on stock injectors and programming blowing up? Maybe you should do a little research, but I'm sure you can find more posts than you care to read about people cracking ring lands in low boost/stock engine applications.
I don't know what GM's reason was for cutting pulsewidth in half when the maf maxes. Maybe it's something they never considered. Or, maybe they figured a stock vehicle doesn't have a chance in hell of maxing out the maf, so if the maf did max out (bad sensor), they cut fuel back to keep from melting the cat's.
So anyway, good luck with your kit. I'm done with this topic until (or 'IF') more information is presented.

I agree with INTMD8 in that the stock engine will NEVER max-out the MAF, so if the computer senses the max signal, there must be a sensor error so it'll cut fuel. This is not limited to LT-1 cars either. Grand Prix GTP's have the same issue. This may come as a shock, but GM didn't intend for people to modify their products.
Furthermore, atmospheric pressure is 14.7 psi. At atmospheric pressure, a bolt-on LT-1 will make 300 chp and about 250 rwph. If you were to double atmospheric pressure to 29.4 psi (equivalent of 14.7 psi of ambient temp. boost), the hp would double to 500 rwhp (which is roughly what is being claimed).
Therefore, to obtain 500 rwhp on a stock LT-1, you would need to run about 15# of boost with either a 100% efficient compressor or a 100% efficient intercooler.
But 500 rwhp with a ~75% efficient compressor and a <90% efficient intercooler with only 11# boost? By this same logic, 11# of boost on a stock LT-1 has a limit of 433 rwhp.
It doesn't add up.
