Same here no timing being pulled on mine.

 

nope no water or water+meth

yep 6psi is my max boost.

What rpm do I see max boost as soon as i put the throttel on the floor.

~2 to 2.2K rpm is when see max boost. Remember this is a Positive displacement blower

 

Wow this thread turned out great so far, thank you everyone so far for the debates... I read about the new KW supercharger coming out, it seems pretty promising. Also can someone explain the science or the difference between the roots and the ct/vt/kw style superchargers? why do some superchargers sound like turbos, some sound like your engine is working its ass of and clinking and others have that winding zip sound.

Your welcome

 

haha can you explain the diff between the roots and the ct, vt, and kw superchargers? like the mechanics...

 

At 5.5 to 6 psi. Yes its stock timing + up to 6 deg at some spots.

but the average timing over stock is 2.5 to 4.5 degrees in the rpm ranges from 3.5k to 6k and that is at 12.1 A/F. I am looking at taking the A/F to 12.4,5 based on Intake temps and my EGTs.
I have been using this timing map on my car way for over a year now.
With heavy track days in 95+ deg weather.

My IATs are always 10-15deg C above ambient even in boost hence my ability to add timing.


This is with the the standard kit + a Moss outlet manifold on the blower ( the Moss outlet smooths out the air flow coming out of the blower increasing mass flow by reducing wall turbulence

Now don't think the standard kit comes with this timing map because it does not


s2000Junky Do not try and increase your timing more then .5 of a degree once you have passed your peek TQ. The gain it provide are minimal and quickley increase your EGT. being that you are centrifugal your peek TQ should be near or close to redline anyways.

I have an advantage over most owners with my sponsorship with a local dyno shop and my personal tuning knowledge.

I have over 100 pulls (dyno dynamics) on my car with the Roots supercharger.
( couple hrs every month starts to add up after a while. )

+ I have a very important tool on my car that most owners do not have or if they do do not fully understand what it means.
An EGT probe.


but me insane no never

 

 

Your asking allot, I'm tired

CT and VT - Centrifugal blowers, aprox 50,000 rpms - gives you your wirlygig sound most of us like lol

KW -centrifugal rotex blower, runs at 100,000rpms. More efficient then the CT/VT centrifugal blowers per boost output. sounds like a electric leaf blower or engine fan = gay lol

Roots or positive displacement SC- screw type, delivers maximum boost much earlier and over a longer duration much like turbo but without the lag.

 

Keep this up guys....LEARNING so much!

Junky and Camu, I have some questions. If I change my power curve N/A to a much more smoother and linear one, with berk header, SAFC ect...will the power curve be maintained and enhanced with the SOS SC? I understand that the boost will be based on RPM. In theory, I would get my power sooner correct? I also keep on reading that with the berk header, there will be some high end loss, so would I suffer from even more of this loss by adding the SOS SC? Anyway to correct that with the NEO?

My goal is to get the following rpm/torque curve:

As opposed to most regular rpm/torque curves you see:

http://www.s2000performanceparts.net/temp/dyno02.jpg

Notice that the max power is lower on the first one, but the power is more linear and comes sooner.I would then eventually add the SOS aftercooled kit.

Will this approach work?
