Good idea but I don't see that happening. Maybe if I let anyone else drive the car.

just from a google search, I found mention that the blow bypass valve was vacuum operated.
with high manifold vacuum (and boost not needed) the butterfly opens and reduces the parisitic load of an useless blower.
with loss of manifold vacuum (accelerating or high power demand) the butterfly closes.
maybe just disconnecting the vacuum hose would do the same as the tie wrapes, but it sounds like a feature you would want
please note this is just keyboard mechanic/engineering as I an humbled by your work

I look forward to see if your modern tech will outrun my old school engine. BTW, I don't get 20 mpg...
Where is this ending? Will you market a kit so others can do the same as you? Or is it too much of a hassle to do, sometimes one finds during a customization like that that it's not worth all the effort? The mpg is not that important to me, don't drive it daily, but the drivablity, the 100k+ miles lifespan and the peace of mind driving it on long trips would be great
Maybe, just like with our cars, it's the journey, rather than the destination?
I think that question was probably asked to Sir Edmund Hillary, Jørgen Jørgensen (one time Danish Ruler of Iceland), and Magnús Ver Magnusson (Worlds Strongest Man 91-96 - although he is Icelandic).

Well, my car is never done so I do not know where it will end.

I do not plan to offer a kit for the LS9. If someone wants help with doing the same install I would certainly help. I already have a kit for the LS conversion but the LS9 is A LOT MORE WORK!!!!!

It was ABSOLUTELY NOT to much hassle and it was worth every second of effort. I couldn't be happier with the result and would do it again in a heartbeat.

The MPG is not important to me either but it is a nice side benefit. The driveability is great and the piece of mind is also very important. In fact, the piece of mind is in my opinion, the most important.
After I installed the LS3 years ago, the car became something I really loved to drive. Not that I didn't before, but it became so much more enjoyable because it ran like a factory new car and I never had a second thought of something possibly going wrong during a long trip somewhere. I know there are folks that get that now with the 351C but I never got that kind of piece of mind when I had my 351C. From a broken drive pin to a coil going bad to whatever, it just wasn't stress free. I have received so much more enjoyment since doing my initial engine change despite some negative comments from a small group of people.
I still have some items left to do to get the LS9 project completed. The biggest thing left is the exhaust. I don't know how much more power I will get from removing the restrictive exhaust but whatever it is, is just icing on the cake. Still can't wipe the smile off my face everytime I think about driving my new car!

You are exactly right, there are three things that control the butterfly, vacuum, boost and the electronic solenoid. You could be right, disconnecting the vacuum line may indeed solve the issue. I may experiment with having it connected/disconnected and also having the boost line connected/disconnected to see how the engine and boost behave. But I couldn't be happier with how it runs with the 2 tie wraps!

For me it was both!!!
Chris, it looks and sounds great.
I checked out the CNC Performance shifter, which has a link to SACC, but can't seem to find it on your website. Can you post a link?
Keep up the innovations too.

Lie,
He's been teasing us with this shifter conversion for awhile now. I couldn't find it on his website either. Bet he'll sell a ton of them.

Hi Lui,
I will get the product up on our website in the next couple of days. A lot has been going on in the background to get this product available on a large scale. More to come on that shortly.
Scott
Looks great!! Congrats. You guys worked hard on that one. Good luck keeping those tires planted!!
Looks like she was having no problem accelerating in the video!!! Great work Scott! I would really like to hear your new exhaust.

Haven't updated this thread in a while. We have been sidelined with other projects but I want to get back and get the Pantera finished. I completed the AirRide suspension and really like the ride and being able to slam the car at car shows. I am now adding ride height sensors to give it even better control.
Here is a picture of the undercarriage...

Since this was asked in another post I thought I would post the link...
Here is a video of our Pantera with the LS9 conversion and cable shifter. It has a pretty awesome sound to it (and we haven't even worked on the exhaust yet).
Here is the video: https://vimeo.com/133242418
Also, we get the question a lot on why we chose the LS9 engine and I just wanted to give a quick bullet point list on why we chose the LS series over anything else:
This is all information that we have talked about in our threads before but I feel like it was necessary to reiterate the information as more people are interested in swapping an LS/LT motor into their car.
The way we look at it is it's our car and we are going to make it how we want it no matter who likes it or not. We are in no way married to the idea of the Chevy crate motors but until another company makes a comparable engine with the value-to-power-to-packaging value that Chevy does, it will remain as one of the best options.

Also, we get the question a lot on why we chose the LS9 engine and I just wanted to give a quick bullet point list on why we chose the LS series over anything else:
- Our first thought was to build a beefy Cleveland motor but we knew that it would not be able to make as much power as reliably as a crate motor and reliability was one of our top 3 concerns. So that meant we needed to start looking at crate motors.
- The LS series is an extremely compact series of engines. Further, the new LT series of Chevy crate motors is even more compact than the LS series. This was the main reason why we chose the Chevy. It offers the best packaging of any crate motor that was on the market at the time. We did consider going with the very common 5.0 Coyote crate motor but we didn't because it is a lot bigger of an engine (wider/bulkier/heavier).
- The LS series also offered the best value based on the power to cost ratio. When comparing engines, the LS offered the most power for the price. When looking at the Coyote motor, it was almost double the cost of the LS3 that we originally installed in the car and offered less horsepower and much less torque.
- When we got tired of the LS3 power, we chose the LS9 because..... well just because it would be cool... lol. It was a logical extension from our original LS3 installation. The LS9 has a similar block design as the LS3 which allowed the engine to fit extremely well, even with the supercharger installed. Now that the LT4 is out, that engine offers even more power in a more compact package than the LS9 so it is a great choice to swap into the Pantera.
This is all information that we have talked about in our threads before but I feel like it was necessary to reiterate the information as more people are interested in swapping an LS/LT motor into their car.

After almost four months straight working every weekend, we finally got a weekend off to work on our own car!
Since we installed the LS9, we have been using the exhaust system that we made when we installed the LS3, including the extremely restrictive LS3 exhaust manifolds.
We started the planning stages of our new exhaust system this past week and are finally getting started on building it.
The LS9 came with what is best described as a shorty header. It is constructed of stainless steel and it flows extremely well for a stock exhaust manifold. We thought about making custom headers but we decided we wanted to keep the engine as stock as possible.
In order to get our exhaust system perfect, we decided to buy some PVC pipe to mock up how we want it to flow. After we got the basic design, we started building it.
We're going to keep some of the details hidden until we get further along but here are some pics of our progress.
We will be bringing the exhaust up on both sides of the engine and out the back.
Not bad for a couple amateurs, right?

That car is awesome ! I dig it...
An inspiration!
