Agreed. GTM's numbers thus far are also with the base level Rotrex on stock cats and exhaust.

There is absolutely no concern about leakage of the intercooler. On the Nissan Titan kit we were using a tube and fin intercooler which was also being used by numerous other supercharger manufacturer's including Magnusson. We had many trouble free years until all of a sudden something changed. The manufacturer was having some serious issues and every single company that we know of has since pulled their intercoolers from them and taken their business elsewhere. We also went one step further on that kit and decided to switch to a bar and plate intercooler for added durability.

Tube and fin intercoolers are good intercoolers, they're basically the same as a radiator. However a bar and plate is much stronger and much more durable. It is a bit more expensive but the benefits outweigh the cost.

To answer your second question regarding what would happen if the intercooler leaked...As I mentioned that did happen on the Titan and on those trucks every customer who had a leaky intercooler received a new bar and plate at no charge and received some additional money for labor. Additionally if anyone lost a motor due to the leaky intercooler (which I think only happened once) then we paid for a new motor.

I think you mean bar and plate?

Sorry, you are correct

Zguy

Thank you very much for your timely response.

Now I understand why you kept the type of supercharger a secret for so long. It has been a while since I have been able to check up on this topic and I am a bit disappointed to find that a centrifugal was chosen. Why?

The TVS is nothing short of an evolution in supercharger design yet it was not used. Did Vortec release some ground breaking new design that is on par with the TVS advancments? Or was a centrifugal chosen for ease of mounting, maintaining the stock hood or just because Stillen is more comfortable with them? Was the TVS even tested? How did it compare to the Vortec unit you are using? What made Stillen choose something other than the best?

I am asking because I respect Stillen and I know that you guys did research a lot of different options before picking the Vortec... what made the difference? Please help me to understand.

I know most parts are prototypes but that intake manifold looks plastic...is it plastic or am i just seeing things. Reason why im asking is on some cars its plastic and it doesnt last long. I doubt it is but im just curious

This question has been covered in the other Stillen thread that for some reason I cant find anymore. Stillen was forced to use a centrifugal because a TVS or screw type supercharger will not work with the dual throttle body setup. I may be wrong but I think there was some other issue with the VVEL system on the VQ37. There just wasnt room and one of thier design goals was to be able to keep the stock hood. (Thank you stillen! I kind of thought the aftermarket hoods for the 350z's were a bit Ricy) I am not exactly thrilled about the Vortec blower myself but they obviously know something I dont. I think they are noisy but thats just my opinion where many others are fine with them.

However I want to to them for the awesome intercooler and intake design. I feel this will definitly give them an edge to the competition and will definitly make the system more scalable for higher boost options that they will inevitably will offer.

The prototype was plastic but the production unit will be cast alluminum.

The picture you're seeing is a machined cast aluminum intake manifold that's been powdercoated black before machining.

It's not going anywhere..

The guy was trying to help, Throttle.

Don't bite the hand that feeds you.
