Preparation for the STILLEN supercharger

Red370

I'm shocked that GTM is still struggling to make 100bhp over stock while this kit is already making over 100whp, Stillen gets mucho props on this one.

Hold up now, before we start bashing all over again remember, GTM has only run a boost at 5psi and stillen has not even said what boost their 400WHP boost pressure was achieved at besides 'moderate boost'. That could mean 6psi or it could mean 10psi, we just don't know yet. Also, we don't know what correction method they are using for the dyno STD or SAE. I'm guessing its going to be STD because everything they have come out with so far is STD

I'm not saying when the results come in we can't all start talking smack but its still a little presumptuous.

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

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.
