Question G5X3 cam and Vacuum???

Will I need a vacuum booster when I install this cam? I have the 114 LSA one and someone mention to me that I will not have enough vacuum for my brakes because of the size and duration of this cam???

When it comes to vacuum, you should be more concerned with LSA.

So if the cam has a fair amount of duration, but a wide LSA there should be enough vacuum to operate power brakes and what not?

Sorry man No Dyno Numbers as of yet. Took her to the track last Sunday on some borrowed ET streets that were dried up. Couldnt hook the car. Still managed an 11.97 @ 119MPH with a sorry *** 1.8 60'. I am goin back on Friday if I can get some better tires by then.

I did Heads n cam at the same time. Its a 2000 z28 M6. Mods are g5x3,comp R lifters, Vinci Rockers(1.7), Patriot ls6 style heads(59cc chamber) ls6 intake w/28lb injectors, Lid/CAI, stock descreened MAF, TSP ported TB, Pacesetter long tubes, duals 3" into x pipe 2.5" out into Spintech Pro Shootout Mufflers, Spec StgIII , Nine ince w/4.33s. Tuned thru the mail by Chris Robinson. Not sure of the race weight but I had only removed the front sway bar and the spare/jack so I am guessing 3500 to 3600 lbs. I am a fattass weighing in at an astounding 125lbs. If that helps any.

BTW nice pic of the Odometer on your site! Min just rolled over the sam number and I wish I had my camera to capture it lol!

The fast ramp rates of the XE-R lobe actually provide better vacum as compared to a cam of equal size on a slow ramp. This means your car will be fine. People run much bigger cams than this and still get off with no problems. The cam is 2 degrees bigger than the X2 FYI.

It's not secret. It's been posted a few times. The answer is in my post above yours.
