So I don't high jack someone's thread, I will ask questions here...
Subject: Randy (Labratt) and Mark's GTX Project
Mike,
I ran Aeromotive SS 8AN Teflon line from the fuel pump to the Regulator, and another SS 8AN Teflon line back to the fuel cell for the return.
That said, which Aeromotive Fuel pump should I buy, the 1000 or the Eliminator, and which Aeromotive regulator? I could potentially be generating 1200 HP out of my new engine, but most likely around 950 HP...just want to buy once.
I also have the MSD Crank Trigger with a locked out MSD Billet distributor, being controlled by a MSD 7AL3 that has a 20* start retard chip...
I have been doing my research on both the Holley Dominator and HP units, and I think I understand a little at this point. Very little...
Okay, you are going to a crank trigger and cam sensor, so how are going to incorporate that into your engine? I have the jesel belt drive on Randy's engine, and will also install one on the Hemi I am collecting parts for, so I guess you could have a sensor there?
Do you have the Holley HP ECU controlling the timing and spark on your car? Or will the crank trigger and cam trigger help do this for you?
EFI is new to me, but it all looks like that is the way of racing future. Sorry Thumperdart...
BR, Mark

On the pump you would be better off asking Monte.. right now I only have fuel control... once I put on the crank and cam sensors I can have a true multi point injection with timing control... I have a crank belt pulley that I made purposely with a 1/4" extra behind the belt so I could add a crank sensor... I just talked with Jerry on his dist sensor set up.. in a week or so I will swing by his shop to see what he has... but so far it looks like I will run his dist set up.. then go coil on plug.... Trendz is a guy you might want to ask some of your questions to also.. and MoparRich since they both work on this stuff... I'm still pretty green on this

I would suggest using a magnafuel pump. Smaller, quieter, less heat, more output under higher pressures. I personally had no luck with using a single A1000 on my car. Not enough output under boost, and loud as a chainsaw. I'm pretty sure Holley also makes an EFI pump, but I have no experience with one. I would strongly suggest using the ecu to control timing. A cam sensor allows: individual cylinder timing adjustment individual cylinder fuel control sequential injection coil on (or near) plug ignition If you plan to use as a drag race unit, the inputs and outputs of the dominator are well worth the extra money for data gathering and controlling peripherals. Contact Rich or Monte for Holley EFI.

Jesel sells a magnet to drill and glue onto your belt drive setup, or you can use your crank trigger for a crank sensor, and grind all but one reluctor off the distributor reluctor wheel for cam sync. IIRC someone mad a crank sensor adapter that uses a jeep 4.0 sensor, if you didn't want to hack up a msd distributor.
I've got a HP ecu I'm actually selling if someone is intersted. Jerry does that 4.0 jeep sensor.. that why I am thinking of going that way

Here's a pict of a mallory dist I did for a SBC. Not a whole lot to it, scope pattern is perfect/ even at slow rotational speed, very clean install, and easily phasable.

The screws hold the sensor assy to the body. The magnet is in the center of the "cap" the actual sensor is molded into the outer cap where the wires are. The rotating cylinder/ring, makes/breaks the magnetic signal between the sensor and magnet.

I like the jesel solution, as long as your not using a factory style waterpump housing, and you are using a distributor cap/ rotor. If you plan on coil on/near plug, the Jeep sensor is small, and you still need something to hold the oil pump drive gear in place, so why not use the distributor as a dual purpose unit?

Good question, my theoretical answer would be that the crank trigger is much more accurate than the distributor trigger, which has to deal with the cam lobe and spring interaction as well as the drag of the oil pump assuming it is at the rear. Camshafts are not infinitely stiff especially when 700# springs are used.
However there is usually a large variance from "good" to "good enough". The distributor setup may fall into the good enough category.
R. Yeah, sometimes I don't make myself real clear. This jeep sensor is used as a cam position sensor only. You would still need a crank position sensor for actual engine position. The cam sensor only lets the ecu know what stroke the engine is in. The cam sensor "event" has to occur within a window of 60 degrees. I think some guys may misinterpret some lingo with the ignition triggering. You CAN use your distributor as an ignition trigger. It will not be as accurate as a crank mounted trigger. There are also "daul sync" distributors. These give the ECU the crank and cam signals to control ignition and seq injection, again not as accurately as a crank mounted sensor. Then there is the crank mounted trigger, used in conjunction with the cam mounted trigger. The accurate part in this equation is the crank trigger. The cam event can swing/ occur in a 60 degree or so window. No cam twist or chain slop would ever get you out of that window. On the question regarding the embedded magnets, I think what you are referring to is the 4 holes you see in the dist body. Those holes are there only because the original mallory distributor upper half is screwed on using those holes. In this case, those holes are not used.

Monte,
Any ideas on my message above on Fuel pump regulators?
Thank you, Mark I went with a complete Holley system... regulator and pump... but I doubt the pump I went with would support your engine... I know mine is good foe 700 hp and I went with #8 supply and return

Hi Mike,
I looked at the Holley Dominator and the Brushless. The Holley Brushless are expensive, however it looks like the ECU would be able to control the pressure for Idle, mid and full...don't know for sure, though.
Magnafuel makes an in-line EFI pump that is rebuildable, but not sure how quiet it is and how durable it is.
On Yellow bullet, there are a lot of complaints about the Holley pumps...
Still waiting for Monte and the EFI experts to chime in.
Thanks, Mark

Thanks, Mark I havent looked yet but I want to see if they have rebuild kits for the pump I have.... I would like to have one on hand.. mainly for DW... I can say that the pump is quiet.. I barely hear it before I start the engine... I wait the 3 second it runs then it shuts down if the engine isnt running... just so the system primes up the pressure
