They aid in exhaust gas scavenging. Highly helpful per its design, on N/A or S/C.
easy? I heard the cam gears are a pain in the ass to install? but it is worth the power N/A no doubt...
so itd really help you if you had no cats to aid in exhaust scavenging?
They are no pain in the arse. Very simple. As long as the installer can read and comprehend the instructions thoroughly. Then double check the work. Passenger side should only take approximately 30 minutes.
They increase the engine's V.E. regardless of the exhaust.
Exhaust improvements will further complement the cam gears.
Dude it took me like 4hrs to do mine lol
but why you were in there, y not replace the cams entirely to go with it? even more power?
How much time with a supercharger already installed?
Let's carry on the conversation of camshafts here. http://www.xr-underground.com/forum/showthread.php?t=55117
Im hopefully going to be installing my cam gears sunday so well see how long it takes for my second time lol
Just mark everything and take pictures. :top:
I agree with Torspd.
On your cam gears, there will be a mark. I believe it is a circle. I put a dab of paint on the chain that lined up with this mark. I made sure when I put the new gear in, it matched this paint dab.
I don't like to edit vendor threads but a few of us got way off topic with camshaft talk. I've move those posts out to http://www.xr-underground.com/forum/showthread.php?t=55117
Running without the cam gears is stupid, but what about running the Apr with out the thermostat? Say you don't have extra coolant at the time, any dangers in not using the 170 thermostat?
Should be OK but all questions for the APR X-1 should be directed to APR.
I can certainly help you out with any questions about the UCON-EMS.
Much appreciated, my question is when can I buy one =P, and when I do would I be able to run the ucon without the t stat?
Also would you be interested in setting up an APR remotely? Or should I try contacting APR? Or should I wait for the ucon ?
All advice greatly appreciated.:adore:
X-1 has been out of production for years....not sure of what APR is doing in terms of support these days. You're pretty much on your own with one of those units if you ask me.
"all questions for the APR X-1 should be directed to APR."
:laugh: Am I correct in my understanding that APR just suddenly disappeared one day?
I would say the X-1 disappeared. Apr stopped making them.
APR did several things for me and I always had good luck.
I know others were not so lucky.
Does that apply to all the people with your superchargers that were sold with them? We are just on our own now with no support? Just curious?
