What does this mod do? What all is involved in doing it?

 

It re routes the coolant so it doesnt go thru the tb so you get a cooler intake charge. All thats involved is re routing the coolant hose and plugging the lines going into the tb.

 

is there a thread that has indepth pictures/steps kinda like a tech article????

 

Here's a link to ls1howto.com I believe the write up is for an f-body, but it's basically the same thing.

 

just take the two hoses that go in and out of the bottom of the throttle body and hook them together with a barbed union i think its 3/8 but not sure. Basically just by pass the throttle body.

 

...you may want to be aware in winter after shut down condensate will form and if parked long enough it will freeze. The newer motors have a tilted TB to avoid this also. You may want to run it in winter.

 

I agree with therock, it got down to 40ish the other night after my truck sat in my driveway for a longass time, when i left home at 6am when the sun was just starting to comeout, i would have to mash the throttle a couple of times after i initially started it up because it had the tendency to stick shut. Kinda sucks, but it takes like 5minutes to bypass and 5 minutes to undo the bypass so when late fall/winter comes just switch it back.

This is good info...I've considered doing this mod a few times, but haven't been able to decide if it would be worth it to me. Winters in Jersey can get down to and below 0* so if I do decide to do it, it will be one of those summerize items.

 

i did mine about 2 yrs. ago, when i was living in N.Y. and never had any problems with iceing, on start up, or while driving. im also running the volant with ram air tube.
on sticking tb. 40* should not be cold enough to form ice, maybe just a good cleaning will take care of it ??
