Well Howdy guys! I just bought a 2007 Crossfire limited after a ton of reading and drooling. I've also spent about 16 hours searching and reading this and several other sites absorbing information.

I have a Rotrex install or two to knock out, another couple of kits to build, then get my spyder back to stock to sell, and then I should have the time to turn my full attention to the crossfire. However, that is going to be a few months down the road.

That said, I took a Rotrex and held it in the engine bay to size things up:







Now this one is a bit smaller then what I would use. It is a C30-94 (400 HP) but for this application I would use a C38-61 which is roughly .5" larger (height and width). The C38 is good for another 150 at the crank over the C30.

The rotrex is simply an awesome way to go. It offers at least a dozen areas of improvement over the blower on the SRT-6. Although cramped, I think I see a way to make it fit. First, I would have to relocate the reservoir. Then fab up a quick bracket to set it as shown on the same plane as the other pulleys. The tight spot is the clearance for the intake. It looks like I would have to run a 90 off the Rotrex and down and plumb it under and forward. This means raising it as high as I can without hitting the hood. I also see another option but I'll leave that one alone for now as it is my second choice.

The outlet side is beautiful as I would run it straight back to an air/water intercooler and into the TB.

I've read about the tuning challenges you guys have had and will spend my spare time looking further into that area. That said, I have a few tricks up my sleeve that I hope will make things easier.

However, what I would really like to do is find out what tool the "shops" are using to tune the ecu? I've read up on the software (that the guy in france with the v-8 swap mentioned) and it looks like it can change some settings in "developer mode". I just haven't figured out how much and how far it will go. Someone has to know what combination of hardware and software they are using and if it is written, i can figure out how to use it., but I guess we'll see.

I'm excited to be here and over time I'll prove myself to be a valuable member. I'm very passionate about cars, I know my stuff front to back, and I tinker constantly. For now I have some clean up work to do before I can really focus on this car. However, I look forward to exploring the limits of the stock motor, tranny, and beyond!
