Lol @ that guy who said his car rattles when he shuts it off, your a dumbass

[steelstrings1312]

whats that rattle noise when you shut it off? mine makes the saaaaame identical sound when i shut it off.

[randallkemp]

@steelstrings1312 The driveshaft rattles with the engine shake when you turn it off. If you push in the clutch when you turn it off you wont hear it.

[steelstrings1312]

@randallkemp oh ok. thanks for the tip man! much appreciated.

Magnaflows suck ass.

[lmrideas82]

WOW THAT SOUNDS ALOT BETTER THAN YOUR SUPER 40s ON YOUR OTHER VID AWESOME

[Heezy2090]

gotta love magnaflow.....do cams make your exhaust louder?

[racinking10]

Is it me or at Wot does It sounds like a vette with corsa's???

Nice Car though Man I just Ordered Stage 2's for 2005 fx4

[chddb]

I have these going in my 07 this weekend. I have the CMDP's. Should I be wary of anything? Sounds great bro! I am hoping for the same sound paired with my Mac LT's and o/r Prochamber

[iceman1682]

Do you have any driveability issues? Brenspeed told me it wasnt a good idea to install these cams without delete plates. When everything is said and done, i'll have stage1 thumprs, delete plates, magnapacks and a 93oct tune from brenspeed.

[randallkemp]

It is ok, I have a Tillman speed tune when Im not racing at the track, just because the Bamachips one it real touchy. I have 3:73's and still have my charge motion plates and it does great. It can be tempermental if you floor it in the low RPM range (below 3000). Dont be afraid of the stage 2's though.

[iceman1682]

Its too late now..the stage 1's were ordered and should be in monday....should be nice with delete plates and 4.10s

[illbreakurface]

@randallkemp @ppeterso22 would u consider using that cam for a daily driver?and wats wrong with it at low rpms?

[randallkemp]

@illbreakurface Yes, I have had it as a daily driver for over a year now. It can buck at low rpms if you are not used to it. If you do it make sure you atleast have a 3.73 or bigger gear in the rear. That will ease the daily driving. I have since added a Procharger, Mac longtube headers, and Mac Prochamber midpipe. I had it dyno tuned down from 536 RWHP until I get the fuel system updated and get a built shortblock. It will still be my daily driver when all is said and done too.

[elnrownr]

@randallkemp so are you saying your making 536 hp w/o any fuel upgrades....isyour motor forged

[randallkemp]

@elnrownr Yes and the motor is not forged. I had the motor downtuned while on the dyno that day. It is limited to 5500 rpm right now till I get my motor done. I have fuel upgrades, a second fuel pump and 39 lb injectors. They are just maxed out and need to be upgraded to a cobra dual pump setup and 60 or 80Lb injectors.

[randallkemp]

@elnrownr Yes and the motor is not forged. I had the motor downtuned while on the dyno that day. It is limited to 5500 rpm right now till I get my motor done. At 5500 rpm I am only at 5 lbs of boost and made about 450ish to the wheels. I also have fuel upgrades, a second fuel pump and 39 lb injectors. They are just maxed out and need to be upgraded to a cobra dual pump setup and 60 or 80Lb injectors.

[lordfridge2]
