"HOW TO" - Boost Actuator Adjustment - Lightning Forum

INFO FROM "CHUCK'S LIGHTNING PAGE"

For those that have never seen it, IT'S AMAZING SEE IT HERE

(AND WORTH PUTTING IN YOUR FAVORITE FOLDER)

THANKS CHUCK

The boost actuator is located on the driver's side of the intake close to the firewall. There are (2) 10mm bolts that hold it in place.

One you can see in the pic and the other is on the backside of the actuator closest to the firewall. Pay attention to the slots location

in reference to the bolts so you will know where you started. Loosen bolts and raise the actuator up until you see the LEVER raise up

off of the STOP. Lower it back down until the LEVER just touches the STOP then tighten bolts. Now, this is the way it was explained

to me but I found that set this close the boost gauge would rise to almost "0" while cruising at 80. I went back and readjusted

so I could cruise at 80 with no needle movement unless I barely moved the throttle (and I mean barely). This setting was probably

halfway between the stock setting and the just touching setting. The first thing I noticed was the needle jumped immediately to

10lbs and climbed from there. Stock it jumped to 9.5lbs and climbed. The total boost also increased by a 1/2lb to 1/4lb more.

I also ran a tick quicker with my fastest mph at the track. The temps were warmer and there was less traction (it rained until the track opened).

I think this adjustment is worth a small amount of speed. Besides, it's free.

would this cause my boost to only boost 2lbs if it is adjusted wrong??

BLKSVT · 01-17-2010, 11:14 PM

Could this be causing my stumbling effect when I try and roll into the throttle and she is just getting into boost?

Bgstew6 · 01-18-2010, 08:07 AM

is the lever barely resting on the stop (when the motor is off) ?

BLKSVT · 01-18-2010, 08:12 AM

Yeah it looks like it's just sitting on stop...I am so confused with this issue I am having...
