How much boost do you typically loose....

Re: How much boost do you typically loose....
Very little boost is "lost" through a good intercooler. A Vortech aftercooler will "lose" less than .5 psi through it. Now, the guage readings will decrease by up to 1 psi because the intercooler condenses the air, so pressure readings decrease both downstream AND upstream of the intercooler.

10 psi without cooling is going to take out your head gaskets (been there, done that). My intake temperatures got as high as 212 degrees on my 3rd trip down the 1/4 mile. With the Vortech aftercooler, now I only see a 10 degree rise in intake temps from start to finish down the track.

Thank you for the replies,

The alkycontrol kit is specifically made for the F-body and has instructions just for that. No home-fabbing, wiring, etc. . . everything's included. His controller is a box about the size of a cigarette pack, but the kit is adjustable for turn-on boost level, turn-on amount, and ramp-rate. It's a progressive kit and it's compatible with 100% Methanol when some of the others don't have the alloy components to stand up to it.

I agree that an aftercooler is not the only way to go, but it's always there working to keep your intake temps down. I have a Scanmaster and monitor my intake temps on a regular basis. Since adding the aftercooler, I average 30 - 50 degrees cooler temps with around town driving. Yes you can pull timing to compensate for the difference, but the whole reason I pulleyed up to 10 psi was to make more HP and sooner in the rpm band.
