ya but how is this all going to affect my headlight fluid?

You need to get baffled healights. The force from the extra HP may force the fluid toward the back of the housing during acceleration resulting in a loss of fluid out the bulb socket.:tup:

damn it i knew something like that would happen

i'm missing something

Exactly!

you have mot checked your headlight fluid lately?:shakes head:

By the way there are also down sides to the "other" S/C design as well. So I was just trying to give some info, not taking sides lol, before someone jumps on me for being a bandwagoner.....

Don't forget the boost fluid too. We might need a boost fluid cooler...

Hmm, You change the pulley to change the multiplier effect of the gear size differences and therefore the speed at which the compressor wheel is moving. Higher speed will yield more boost as long as the turbine wheel is within its efficiency range.

Changing the housing would be like getting a different trim and thats the same as getting a whole different supercharger.

You made your post sound like you were talking about spooling when you said "full spool". I don't know if you know this, but spooling refers to the amount of time it takes air exiting your engine to spin up (spool up) the exhaust turbine on a turbo. You are talking about a supercharger spooling? It doesnt spool, it spins up and down with engine speed. That engine speed + gear ratios between the crank pulley and the sc's pulley is what creates a certain speed in the compressor wheel. You are right about one thing though, the housing does affect the way power is delivered because different sized compressor wheels have different effects, speed being the same, with relation to their size. I didnt say it didnt, I said it doesnt have a difference on the "spool" of it because it is belt driven.

The size of the compressor wheel has no bearing on its speed. OK yea the tips of the blades are spinning faster because they are traveling more distance in the same rotation, but thats not what we are talking about here. Whether the compressor wheel is 2 inches in diameter or 4, its still spinning at a certain RPM that is produced by the gearing size differences in the pulleys. A bigger wheel should in theory move more air at the same RPM as a smaller wheel, granted I think each size probably has a different peak efficiency speed, I don't know, I didnt study turbines or fluid dynamics in college. Remember we arent changing the compressor wheel size when you upgrade, you usually change the pulley size to increase the multiplier effect and speed up the compressor per a given RPM and therefore making more boost. That is why bigger housings make more power, because they can move more air per rpm than the smaller housing. In other words they make more boost per rpm. You would only move up in housing when you have maxed out the efficiency zone/speed of the smaller housing.

You even brought up turbos and you are confusing the size thing with the SC. The turbo's are the ones that will produce boost quicker when they are smaller, but thats not because of the smaller compressor housing, its because of the smaller size of the hotside that needs to be filled up and spun up with exhaust air. The smaller that is the quicker the shaft spins up the quicker the compressor builds boost.

I actually think we are both speaking about the same thing here. By "spool" i meant reaching optimum RPMs to produce Xpsi. Granted the word is more befitting the turbo application, but SCs do spool. Given it is by motor RPM and not exhaust.

My point is that given the pulley and compressor size differences between the Vortech blower and the Rotrex of the two competing kits, the torque curve differential is explanable by the amount of CFM moved at lower RPM ranges by each. Again, no one from Stillen has responded stating that I am incorrect.

That said, I am still waiting for Stillen to respond to the PSI levels and why it's so important to keep them from the masses until a "Press Release." This is a bit confusing. I am also waiting for a response on whether or not Vortech has ever released a kit running 10psi or better that was CARB legal. (I already know the answer to this one)

We will release our boost number, in our press release. It's not like we think we have some magic amazing boost number. Obviously it's above 4 pounds and below 10. We just prefer to announce that number in our press release.

To be honest, I have absolutely no idea how much boost Vortech has used in some of their previous kits. That would be a question for Vortech. Keep in mind this is not a Vortech kit...This is a Stillen kit utilizing a Vortech compressor. All of the engineering, testing, and development has been done by Stillen.

No magic number, no sale. Every Stillen S/C should include a magic # in the box!

Nice, we're getting there.. is it above 7 and below 9? :p

FAIL lol. He can still get you with decimal points, now he can answer with between 7.1 & 8.9.
