Mike I am doing a little replumbing on my powerdyne supercharger and vortech aftercooler, getting ready for summer. My question is, with my tune what is my idle air control doing at wide open throttle under boost? the reason I ask is in the origanal powerdyne install they route the hose from the IAC to the boost side of the system, I noticed that some vortec install show it in the intake elbow of the supercharger which is perfict for my install, but will I loose boost by doing this? I can change it with out a lot of problem but the install will not be as neet. But power rules I don't want to loose boost, as always youre experties are appreciated!!!!

 

Hi Chuck,

Good to "see" you again!

This is something you'll need to give us a call to go over properly with what you're doing there, thanks!

 

Thanks for the reply Mike I hate to take up you're valuable time at the phone I know how busey you are. I did some investagation took the valve off and coud see that ther was no way that the valve could hold back boost, and decided to replumb it to the cool side of the aftercooler that way it is presurized equaly under boost and getting the benefit of the cooled air even at idle.
First chance I get I want to do some data loging and air fuels and get the tune nailed down. The aftercooler realy makes a differance, espesialy like today with an 83 degree ambient it ran like it was 55 degrees.

 

Hey Chuck - don't you worry about that, you call me anytime, OK? I always enjoy talking with you, we've been tweaking on that truck (I say "we" - meaning really *you*) for some time now, so I';m tickled to see you have a good intercooler installed, etc., and can't wait to see your next round of datalogging on it to see if we can crank up eve more power for you, or whether we need to make other adjustments in the tune, etc.

Those 4.6's can be funny - one will take 17 degrees of timing to hit peak power, where another will want only 12 degrees with a different blower & intercooler configuration, so it's nice that you have the Vericom there to do the testing with like you've been doing for years now.

Talk to you soon!
