Ok guys I got a couple different questions hopefully someone can give me some insight on.

1. I am getting ready to replace my timing chain and most the ones I have looked at say I can increase or decrease the timing 4 degrees. I was wondering if that is true or not.

2. I'm trying to find the crank sensor. I know it is on the rear passenger side of the block but I can't seem to find it. I located the ground on the left passenger side and was wondering if someone can tell me where it is located compared to the ground cable on the rear of the block.

3. This is gonna sound realy off the wall so bare with me. I have been looking at the electric superchargers. I know they don't work, but I was thinking of using one for a base design. I was thinking of using an electric drillmotor hooked to a dimmer switch to control the motor to increase and decrease boost. I also planned on installing some type of gauge to monitor the boost psi at all times. I know it sounds very crazy but do you think it would be possible.

 

I'm just addressing your 3rd question-I don't really understand what your idea is with the drill motor and dimmer switch thing but anything over 2 psi of boost you are going to have to retard your timing in proportion to the amount of boost which means you are going to need another ignition system, Crane makes the Crane Fireball which is an excellent one with it's own MAP sensor that does it for you automatically + it has a manually adjustable base setting,if you don't retard your timing under boost your motor WILL GRENADE. Also when running under boost on the magnum you will need an FMU controller which basically increases fuel pressure in relation to the proportion of boost being run at any given time which also means on the magnum you will need to upgrade your "in the tank fuel pump" or purchase an auxillary pump to maintain 50GPH@70PSI for reliable fuel feed under higher boost conditions, ESPECIALLY at the higher end. Also, if your motor has over 100k on it and you run even 5 or 6 psi of boost for any sustained amount of time you will be replacing the headgaskets soon. Good Luck with the project and post some pix when your done!

 

I can answer all 3. #1. why do you want to advance or retard the timing? Have your motor at TDC and line up your marks on the sprockets. On that motor you just set the distrubutor in the middle and it adjusts itsself. Thats the purpose of a CPS and a CPS...oops same abbreviation. I meant camshaft positioning sensor and crankshaft positioning sensor.

#2 The crankshaft positioning sensor is on the passenger side of the motor. It fits in a hole between the block and the transmission. Its pretty much on the top side of the housing. You can see if you crawl underneath the truck. Its hard to see from the top but you can feel it. Just feel down right behind the head on the passenger side. Its held on by two allen head bolts. Good luck if you have to take it out and replace it. Its a bitch to do. I broke mine pulling the motor out and had to replace it.

#3 No. You have more vaccum than an electric fan can boost. Have you ever held your hand over the intake and crack open the throttle? It'll suck your hand down in there pretty hard. The vaccuum will be turning the fan blades, not the electric motor.

 

i agree with the fellas above... i know nothign about chargers and that even makes sense to me.. youd have to overcome the natural vacum of the pistons tryin to suck air in .. being naturally asperated(sp) and then after that amount..produce anough to make extra HP along with the other mods to keep the motor running right.. its a coold idea. and i could see where your going with it... an electric motor that ran like some 100,00 rpm would in theroy work.. but again it would have to have the HP to puch that much air.. and after dinking with the "prototype" and money... you coulda bought a regular charger.. it would be cool though..

 

I realy appreciate everybodys insight. I have always been bad about tinkering and trying different things.

I want to advance my timing some might actualy find kind of odd. I hear everybody talking about pinging and my truck has never pinged. I know that is a good thing but I just don't think my timing is far enough advanced. I can tow 2000lbs with the 93 octane setting on my hypertec running regular gas and not ping. So I figured I could probubly benefit with a little more advanced timing.
