See how ya like this one...only cost me $145.00 materials and 10 hours of fab time with torch and wire feeder... just installed a couple days ago.... I haven't taken the installed pic yet, was just gettin ready to paint it here...built out of 8 inch structural channel, 1 inch heavy wall tubing and 1 1/2 x 2 inch heavy wall tubing...and will take a bigger hit than a ranch hand...

I'm curious how he did that though... drop it in drive , stand on the brakes and trick someone to turn the regulator **** to no more than 15 psi or so? How would you do that on a manual?.... I can see me taking the hood off mine and getting / tricking my wife into riding on the engine while I cobbed on it going up the canyon road to build boost so she could twist the lil **** Ha Ha
My regulator is set at around 21 PSI. I set it with shop air before I installed it and fine tuned it later with my Aeroforce scanguage which gets it boost reading from the PCM. The PCM never sees more than 21 psi even though I make 30 psi. Not all OBS trucks need a regulator.
