whats the way to calculate how many RPM's your blower is seeing? must be able to figure it out by RPMs, cog, and pulley size. so s trim with 3.12 pulley and non rev up cog set up see's X amount of RPMs(the blower) on avg at 6600 rpms(engine speed).

anyone create a chart to figure that yet?

 

Go to vortechsuperchargers.com and they have a rpm calculater.

 

perfect. thankyou.

 

Some better and up close pictures!

 

The one in the original picture is set for 12psi cracking pressure in that pipe.

 

I see it's up on the site now....

$245!? Holy *****!! That's a lot of money for such a simple instrument.

 

I have one of the older ones. The new one looks much better and looks like it will bleed more air, but $245 is a little high. The one I have was only $79, but it is a much simpler design.

 

This one is also 5x larger, is more adjustable, more durable, looks better and includes a bung!!!!

Either way I am game and am going to buy one for my Z!!!

 

Did it work out for you? Any issues at all? No one on here has really done this, or at least posted about it.

 

bump for graph.....

 

Another thing I would suggest on future revisions is a way to bleed post-intercooler boost back into the intake tract before the supercharger. Compression->heat removal->relief == significant temperature drop and a way to recover some energy that would otherwise be wasted on air bled off.

 

Wow, I had no idea it was 250.. Prob will stay with my zen bov....

 

no reason to even put this after the intercooler. why cool extra air?

 

If the intercooler is sized big enough for even the extra air, then once that air is released it will be cooler then the ambient air temperature. Instead energy being expended to compress air then blow it back into the atmosphere, some of that energy will go towards creating a cooler inlet air temperature into the supercharger.

I don't know how much gains this would have in the real world, but theoretically it should result in more mass flow and more hp out of the engine.
