sigh... you guys make me want to get Turbonetics single turbo. sigh...

 

Do some serious research before you go TN. You can get big #'s but there are a lot of issues with that kit.

 

question for the stillen guys - how much boost does the stillen make at different rpms?

does anyone have a boost gauge? What boost does it make from 1000-6600 rpms?

I've been hearing it makes 3psi at 1000 and then rises at 6 or 7 psi to redline - is that true?

 

I can't really tell you @ what rpm makes what psi but when I'm at WOT, I know that I already @ 8~8.5psi b4 redline...I'll test it out let you know

 

you have a boost gauge I'm assuming? or you going to take it to a dyno or something. A lot of people lately where I live (1300 ft above sea level) say that they make around 7.5 lbs of boost at redline - might be the elevation though

 

Yes, I do have Defi boost gauge...but I'm sure I'm hitting at least 8 b4 redline though

 

oh you're stage 4, ok that makes sense then

still boost from a stillen isn't interchangable with boost from a turbo or vortech because of different levels of parasitic loss from the design of the blower/turbo. I mean someone could be making 50 psi and still only be making 300whp if the efficiency sucked bad enough for the engine to drive the blower

 

You should be making full boost at around 1800 rpm on the Stillen SC all the way almost to redline where it starts to cut back a little.

 

No, it does not make full boost at 1800. The boost comes on immediately but keeps trickling up until redline. I will get some psi/rpm estimates the next time I go for a drive.

 

I'm going to guess it's around 3-5psi at 2000 rpms, up to 7-8psi at redline
