Preparation for the STILLEN supercharger

Buddy Revell

No, my numbers were just hypothetical. The curves for the GTM and Stillen dynos were a bit different than that. They had bigger differences in the mid-range and a smaller difference in the top end, but I didn't use those because those aren't the final numbers.

Oh alright, I didnt pay too much attention to that since Stillen's numbers werent final, but there you have it. That is my opinion. What do you think?

Also just want to add.... when you get into GTM's stage 3 kit with the bigger compressor housing, that difference in mid range between the two kits disappears since now you are running similarly sized units.

Zsteve

So are you saying one kits stage one will be smaller than the others stage one? So one will be good for low-mid gains and the other for mid-high gains?

Yup ignore button has been put to use since i last posted, so I can't really know if he posted anything back, not that I care. In fact I'm taking down all my unnecessary posts to reduce clutter.

Absolutely lets get back on track with this thread.

Yeah well, I'm sure Stillen will correct me if I'm wrong and I dont want to speak for them, but the stillen Stage 1 compressor is the same size as the other stage compressors. The only thing that changes is the pulley and tune. That's why its very easy and cheap to upgrade.

GTM on the other hand has different compressors for each stage, so yes the GTM stage 1 compressor should be smaller than (less peak power in exchange for a bit more low end torque) than the Stillen Stage 1.

Zsteve

Well that makes things more interesting, I will stay stage 1 if I get one so I guess I would want more tq than high end hp. But as always, once you have the power you want more.

I'm curious why you think its better to run a compressor out of or on the low end of its efficiency range rather than just be realistic about your power goals and buy a charger based on that from the beginning? I can't see choosing something based on what i might do later when its not the best option for what i am building right now.

I think it comes down to people becoming power hungry when they are exposed to boost. Giving a kit that produces great numbers out of the box is great, but giving people the ability to make big power when they are ready without changing major components, even better.

The same design philosophy is used by Greddy with their twin turbo kits.

It only took 66 pages but we've come full circle!

As we said in the very beginning of this thread one of the things we learned with our vq35 supercharger was that people might want really good low end power today but next year they generally want to bump up that power output. Which, as I said in the beginning, was something we kept in mind with this supercharger and one of the reasons we chose the vortech blower...it is very easy and inexpensive to add power later on.

Zsteve

But I think he was meaning if you buy the under powered kit to later upgrade, then upgrade right away.

Interesting points. Thanks. It'll be cool to see more performance data on all the different stages for these kits when they are eventually released.
