No, I'm actually a glass half full type guy. I'm an optimist.

And that's why, for the record, I'm not saying that the work should not be appreciated, or that it has no worth or won't be of benefit. I'm not saying that.

I'm only stating that any work where the investigator is also one of the test subjects, or his offerings are among the test items, is going to be open to scrutiny, and that is as it should be.

Now people don't like me saying that, but it's the truth.

Do you have any idea as to how much money they get for having the engine contracts with these racing teams? These tests and results are peanuts compared to those who have an LS7 and plan to modify it with a new valve train in the next year or two. Take off your tin foil hat and just be thankful someone gives 2 poops about our motors and is putting their money where their mouth is. Now hush. I think we get your point. And 99% of us could not care any less. Unless of course you are going to spend 100k+ and do your own independent tests.
Judging from your attitude above and "tin foil" reference, and then suggesting that I do the testing, do you really think that any test which I did on this, would be truly independent and unbiased?

You'd be among the first in a long line in here screaming and shouting that anything I came up with, could not be trusted, before I could even get started.

And you'd be well within reason to be concerned about the above. I'd have no other choice, based upon my well known position on this matter, but to recuse myself from any testing procedures with regard to this issue. As such, I'm not going to spend the 100 grand for the testing equipment and do what you suggest by conducting a test of my own.

You know, on a serious note, people actually sent me PMs declaring this attitude demonstrated in your post was pervasive, and I thought they were crazy.

I wonder just why some of you are awaiting the results of these tests. As for many of those like yourself, it seems to be nothing more than a formality.

But I'm going to leave you all in this thread to carry on with your vigil.

Plenty of other discussions going on elsewhere

Instead of what, hanging on to every word that you have said as if it were the last word? Bottom line is that you were one of the most vocal and adamant preachers of the "you are stupid if you do not change your valve guides and switch over to SS valves" message which caused panic and concern to run rife on this forum. Katech has always said that they feel that this is an issue that affects a limited amount of engines and is probably not something that you should "freak out" about. They have also said that if you do decide to take preventative measures to avoid any type of valve failure then change the guides and replace the stock intake valves with a similar weight TiMo valve that they offer but there is no need to replace the exhaust valves. You again felt the need to argue against that saying that only fixes half of the problem, why spend all that money and not switch all of the valves, switching over to the much heavier SS valves is already "race proven" over time, tons of shops recommend it etc. etc. etc. Bottom line, you have already convinced your self that the configuration that you wanted to run was best. You then went on to repeatedly hammer home to everyone that "fix" as the right way of doing things and defended that through posting a seemingly never ending and frankly exhausting amount of quotations from previous posts on this forum.

Now you are doing the same thing here. Bottom line, every single person on here knows that you feel that switching over to SS valves is the correct fix for you. We all now clearly understand that you feel Katech is biased and that whatever findings they post are also going to be biased. Great, thank you for giving us your input. I and I'm sure most others on here would like the opportunity to first actually see those testing results and then come to our own conclusions about the validity of whatever those results might be. I have absolutely no interest in seeing this thread turn into another '06 Quicksilver Z06 debate with page after page after page after page after page of you quoting past posts and endlessly attempting to ram your opinion down peoples throats. In one day already you have managed to consume nearly 3 pages. If you keep going in a week we are going to be wading through 20+ pages of garbage. This thread was started by Jason to discuss some testing that they were willing to do, please respect that. If you want to start a debate about "this test being biased or not" then please, please start your own thread so that this one does not get completely destroyed and we all do not have to suffer through reading all of it.

Nope. People would still send their heads to WCCH, they'd simply spec OEM valves instead of solid steel. Katech wouldn't make a dime. At best they'd sell a few sets of titanium valves, which they seem to say is overkill for most applications and could be sourced elsewhere if demand warranted.

Your charge of conflict does not stand up to logical analysis; they have nothing to gain.

Who are these "everyones"? Can you post up a few quotes to validate the basis of your illogical two-wrongs-make-a-right argument so that we can determine if your claimed wrong even exists?

DH,
Running a test and collecting the data is the easy part of any analytical test. It’s the reduction of data, analyzing that data, and producing results that everyone can understand that takes time. If Katech were to just throw out a spread sheet with a bunch of numbers, most would not have the tools to come up some results that they could use. Worse, the wrong conclusions could be made resulting in erroneous decisions. Trust me, I’ve been doing this for many years. Be patient, grasshopper…

Howie,

This takes time and when you're doing it on your own dime you're also juggling LMPC, TA2, GT1, Grand-Am and World Challenge teams. This week some key people are on Belle Isle for the Grand Prix.

Jason,

I am patiently waiting.....

Got my order from you a week or so ago and want to review your findings prior to finalizing the path forward on the heads.

PS - the show painted Fast Intake is KILLER!

C'mon Jason - just tell us that only Katech titanium exhaust valves, PAC springs and - optionally - the Katech Torquer cam installed by Katech or Katech-authorized vendors can safely be run in these cars or your Z06 will explode in a ball of aftermarket shrapnel and flames... killing thousands of innocent baby kittens with the resultant carnage.

Afterall, you don't need experts and number crunchers when you're just going to push Katech products with unmistakable bias and test manipulation, right?

Do you blame him? Do you realize how much money wpuld take to build a similar shop? The whole purpose of the test is to prove how well setup is katech's combination! I have never had a single issue using katech products! And these types pf test reinforce the great product offered!

Katech is not here to sell/help other businesses. They are here to promote qith their own equipment their own products

Nailed it.

The point is not to sell a few more camshafts or valves. There is a bigger picture. The point is to show that Katech is the go-to shop that uses the same technology for it's race teams as it does for it's private customers. Katech is a shop that can answer the tough questions with test data rather than guesses and that elevates us above many others. This thread has probably done more for overall brand awareness and understanding than it will do for individual sales. 19,000 hits and counting...

Fair enough. I just wanted to know what kind of time frame one would expect to analyse this data. An hour, a day, a week ..... what?

I thought it might be a simple "setup A floats at xRPM, bounces at yRPM" formatt. Surely this might/could have been jotted down at the end of each test and posted up rather quickly by you.

So I am no going to assume there is a lot more to this .... and be patient for the results.

Dumb question, but if my WCCH stage 2 heads have increasing hp right up to the 7100 rpm rev limiter can they still have valve float at the 7000 rpm redline?

The thing is... I do appreciate the info offered. It is extremely valuable. Any team, shop that has this type of equipment, certainly deserves our business... It is one of the reasons why the business as an overall is a little more expensive. But, you do get what you pay for.

And I for one am glad Katech is stepping up to the plate.

(obviously my post above was satire reflecting the conspiracy theory comments around by a select few that your efforts would be less than transparent)

I have no idea what the specific information that is going to be released is but I think that it is quite a bit more complicated than that. I've discussed with Jason what's involved with doing this testing and I think that what a lot of people are not realizing is that while Katech is certainly not a 2 man shop they are to any of us that have come from any type of large corporate background definitely what one would still consider a "small business". I came away with the impression that it takes nearly a full working day just to set up and run one configurations. Keeping in mind that they tested 7 different configurations!!!! So all of this testing is quite a major undertaking.

To maintain running your business, meet current customer demands and not impact current projects plus handle all of the engine work for several race customers for a major event this week (plus have people on site there with the teams) is pretty taxing for any company. Give them a little time, I'm sure that they will have everything posted up in a week or so
