with many threads saying its bad to hotwire due to dropping case pressure then some say it increases it what is really going on here is it a good thing or a bad thing? yes i understand at idle no good but using it at rpm does it negatively affect the IP's life span or injectors? i have mine on a switch and use it every once in a while if racing or pulling a hill but never really below 1500rpms. you can deffinately hear the timing rattle when its on.

 

A hot-wired KSB will help keep the case pressure up so you don't loose the dynamic timing under WOT conditions. It generally won't hurt anything when used on the occasional dyno/drag run and such.

 

It also depends on which KSB set up you have. Early KSB's got power with the engine hot; later ones got power to it with the engine cold. OK to do the early ones for full time operation which is just bypassing the temperature switch, generally bad to do the later ones because of the case pressure issue.

 

He's intercooled....

 

Flipping the switch was always a 30-35hp dyno verified gain for me. I wouldn't use it all the time but the occasional flip doesn't hurt a thing.

 

Yes I agree, I wouldn't leave it on all the time, but when you need it then use it. I got a proven 12 more hp when i dynoed with it on, I'm not running a lot of timing though either.

 

Sounds good. i know it makes a difference thanks guys

 

I have mine so I can hook it to my hobbs switch on the water/meth. Turns it on at 18psi.

 

id made me lose 40hp on my dyno runs.... my guess is the timing spacer plus the switch being on doesnt help you.

 

There's gotta come a point where you are running too much timing. Found it!

 

where may that be?
