A boost leak is a leak regardless of how minimal it may be. The higher you try to turn the boost up the greater the leak will become. In addition, if Sam is such a perfectionist, than why was the car not dynoed with the headers after the boost leak was rectified! That is the first thing I would have done. But at that point he had already convinced Shumby to put the stock manifolds and stock cats back on the car.

I would never market a product with the selling point of having to keep stock manifolds and cats to make power. This is HORRIBLE advice and it goes against everything that has been proven with superchargers for decades.

The bottom line is that specific kit is inefficient and apparently isn't creating enough volume to make power through the headers. I have no doubt we will have no issues making power through the Stillen kit.

Now you have our headers as well and are going with a larger head unit. Your results may be positive. I am in for results and hopefully from an independent dyno, not GTM's!

Thanks, Tony

Tony, Worked out the exchange with Semtex, you want me to give you a call again this afternoon?

Yes please do. Give me a few hours if you can...

Thanks

I won't be gettin home for another 3 hours, so it won't be till after that.

I'm glad we agree :tup:

+1 :iagree:

Using that philosophy of a leak is a leak, why is that if a small oil leak develops the oil pressure doesn't drop to nothing? Tony is right when he says it's the capacity of the pump to be able to handle it.

The reason that the LTH's were not reinstalled was due to a very important issue ..... time. SHumby had to return home and time was the issue plus Shumby wanted a minimal powered stage 1. To achieve that the stock headers and HFC's were reinstalled, at Shumbys request. There was little time to experiment, nor room to increase the boost with different pulleys as it wasn't what SHumby wanted. Isn't the customer suppose to get what they ask for?

In retrospect, Shumby shouldn't have not made the general statement that the LTH's do not work with the GTM SC kit but he was partially right. The LTH's will not work with the Stage 1 6 psi pulley (CARB) as the result is disappointing. In reality, if someone wants a stage 1 CARB kit and expects the more efficient LTH's to make more power, it has been shown that it doesn't work, as the Rotrex SC, stage 1 CARB cannot make enough CFM to make enough power without moving the kit beyond the CARB approval level. The customer did not match his expectations to the equipment he purchased as it's not balanced.

When you think about it, a Stage 1 kit was installed with a 6 psi boost setup. As I understand it, it only made 4 psi with the LTH's installed. No reports of dyno results were given for any of the dynos performed with different pulleys or test pipes. Why? ... who knows. Why isn't Sam jumping in and clarifying this issue? .... don't know. Maybe it's a personal issue between Tony and Sam? .... or maybe Sam hasn't had time to test different setups?

I just know that I enjoy talking to the both of them and they are very knowledgeable about what they talk about.

I don't believe Sam has said that stock cats HAVE to be used with the GTM SC kit. I'm sure further testing with HFC's, test pipes, and LTH's a real result will be shown with different power levels with each exhaust setup that will match the different stages of the GTM SC kits. The CARB kit is designed to work with stock headers and cats, to achieve CARB approval. So in essence, it did exactly what it was designed to do.

The stage 1 probably is inefficient since it was designed to be used on a stock car with stock headers and cats. This is why Stage 2 and 3 results will be most interesting. I would love to see what a Stillen SC kit will do with FI LTH's. I'm expecting the same type of result with the Stillen kit boost numbers as GTM has experienced with the test pipes and LTH's. I have no idea what will happen with the power curve and a free flowing exhaust but until someone actually tests this, it's just speculation.
The more information out there, the better it will be for us all.

Your not playing nice Tony.... it has been noted

I will not be installing the LTH's until I have further information in which to judge the results of a change to the exhaust. Besides I will be installing a set of Berk HFC's after the LTH's anyways (hate the smell) Just finished up the design and will be ready for the change when the time comes. For now, I'm hoping to just use the Berk HFC's with the stock headers. I'm awaiting the dyno results for each stage and exhaust setups, like everyone else before I even consider installing a set LTH's.

I hope I haven't bored everyone with my opinion but the forum being what it is, begged a response. BTW .... where the hell is Shumby?????
I'm tired of defending this install on second hand info and just my observations.

I'm sure if everyone just takes a moment to think about it, you'll see where my thought process went and why I have the opinion I do.
I haven't talked to Sam about Shumby's install and results yet, so this opinion is just a collection of information, observations and me talking to other experts in the field and sharing opinions.

I'm done talking about it and yes Tony, I'm displeased

Ooooh Tony, you've been a bad Monkey! :shakes head:






:bowrofl:

tony please respond to my PM I need an answer to it soon.

and I finally found a awesome tuning shop. guys knows all. rebuilds engines, does everything himself. is currently working on a 4.2 custom build stroker kit for the 350Z and a 1200HP R34.

He will most likely make a custom ECU for my car

horray

Without proper troubleshooting (which there was not) that is a highly irresponsible comment.

Low Numbers With LTH-->Leak Discovered-->Leak Fixed-->Dyno With LTH Still On-->Low Numbers=You Can Say The LTH Don't Work

Low Numbers With LTH-->Leak Discovered-->Leak Fixed-->Just Assume The LTH Was The Cause Of The Low Numbers And Not The Leak And Put The Stock Parts Back On-->No Dyno With LTH-->Good Numbers=It May Have Been The LTH And It May Have Been The Leak But Due To Incorrect Troubleshooting You Don't Know=Major Fail

When you troubleshoot ANYTHING you only change one variable at a time. You should have only fixed the leak before the dyno (one variable) but instead you changed two variables (fixing the leak and putting the stock parts back on). A Logic 101 student with no mechanical skills could figure this out... it's frightening that a paid mechanic couldn't.

I'm handwriting you in on the next presidential ballot. :tup:

Whatever ...... your putting too much emphasis on a leak that was quite
consequential..... a non-issue as well as your rant ........ :leghump:

My fellow Americans... :happydance:

Even though I am out of town I wanted to take a moment to check in. I will be back in the office Monday July 12th and header production will resume.

Mine should arrive today!!!! Looks like it'll be the 17th before I get them installed. The Z is in the shop getting a new transmission at the moment. (Sixth gear synchro was going out.)
