G35 Supercharged

the stillen is still a good one just a bit less efficient than the vortech but you should get the one with the intercooler. this thread was deffinatly a complete whaste of everyones time why dont you just start installing it and when you run into a problem or blow something up then come back for advice and start a new thread worth reading.

there some advantages the twin screw stillen has over the vortech.
The twin screw is instant power vs the centrifigual sc with a little bit of lag. Driving a twin screw v6 is really like having a large NA v8 in terms of response and low end tq, so its better for daily driving and auto cross.
The vortech is better if you want all out hp and drag racing or highway racing.
You can squeeze out more power if you machine down the sc pulley on the stillen.

Even machining down the pulley puts the blower out of its efficiency range and it will blow hot air.

There would be advantages to a properly sized twin screw, Stillen unfortunately uses a blower that is way to small for a 3.5L The Stillen is fine for a slight bump in power 330whp is going to be pushing it for most Stillen setups.

I am not totally versed on them Stillen has never really interested me. But they are actually roots blowers not twin screw. Roots have 3 lobes on each rotor and a twin screw actually has a male and a female rotor twin screw are typically more efficient and have lower intake temps.
It is fairly well documented that it is out of its efficency range in our mid-high rpm range. It would be good for stop light to stop light action though. Just don't expect to get much over 300whp if those are your goals it should be fine

From the looks of it, it might be just a rebadged kenne bell supercharger. I think it would probably cheaper if he just retro'ed on a 2.2-2.4L kenne bell sc to his g35 with air to water intercooler.
If the stillen is at least a 1.8L, then i'm sure he can do around 350whp if he upps the boost.
I made around 370whp on a dynojet and 338whp on a dyno dynamics on my mercedes C32 AMG with the 3.2L v6 and 1.8L IHI SC but at 20psi.
Since the vq35 has higher displacement and compression ratio, i'm sure he can probably at least hit around 350whp if he ups the boost with a smaller sc pulley.

He bought the stage two, so he's intercooled, so he has room to increase more boost and still make more power.

I have never seen anyone make more than 330whp even with stage 4, it is an Eaton M62 blower if I recall right and they have a 1.035L displacment.
Here is a guy that had one from my350z.com and what he made
Believe it or not with stock exhaust mine made 320rwhp stage 4 and 300 rwtq, with the beautiful Stillen True Dual Exhaust it made 318rwhp and 308 rwtq. This was with Stage 4 pulley and custom tune by Stillen with a 91octane/ 100 octane switch which worked with their piggyback ecu..I think that Supercharged made 330rwhp but I could be wrong, oh well..Still 320rwhp is like 375 flywheel far short of their 425hp claim for stage 4...

If the stillen is a eaton, then i take it back. The stillen is total junk..lol.

eaton makes roots type not twin screw. and buddie may be right it looks almost exactly like the m62 which is 62 cu. in. and i think a liter is 61.
