accusump

ng8264723 Chris you are working come tuff hours. As far as mounting the accusump you can mount it just about any place. Mine is mounted to the outer frame rail on the R/S of the car. It has electric soleniod to turn on and off in the car. If you run it under the car body, add shields to protect it from road debries. A small stone can dent the case of the tube and it will not work. Some guys mount them on there cross member in front of the motor. This makes for a short run of line to connect. 28 pounds is not alot of extra weight to carry unless you are Nascar or 1/4 racer. Adding the weight makes it a little easier to balance the car in all for corners. The guys that race on the track put there cars on scales with there weight in the drivers seat. All this goes into helping a car handle better. Mount the tank where ever you have room and can get to or work on if needed. I have a gauge on mine and you want to be able to read it. Some guys run them from inside the cars with just a manual valve for on and off, on the passenger floor. I think you can mount it in any postion if needed. I would check with accusump before doing this to be sure. Rick L Hey Chris, get off the midnight shift and get a little sun

If one does not race, how important or not, is a pump for a driver that the car may sit for several days without running ? At start up, my pressure takes a few cranks before it reaches 40 lbs. Usually during this process, it also takes several cranks for the fuel to reach the carb. anyway. So, does a engine need a pump in my application, or is one just a waste of money for something cool to have ? I realize people that have one will say they need and love it but, lets be straight forward.

Unless you race, it's a waste of money and even then I question the need for one. As far as "dry starting", ever tear apart a motor that has sat for a year or so? They still have a nice coat of oil on everything. Your engine is typical and I wouldn't worry. Unless you want one just to say you have one, save your money.

FUNFER2 Kevin you didn't answer the phone the other night,

you asked 2 questions,

You owe me a quarter.

The bottom line is this, "IMO" I would have one on everycar made. The down side would be motors running 200-400 thousand miles on the orignial bearings and internal parts. Dry starting ANY motor is where 70-80% of bearing wear happens. MOst of the oil falls off the bearings and returns to the oil pan. If you run a clinging oil like I do in my trucks, there is less of a dry startup and seam to have quicker oil pressure in the motor. The race motor in my cobra is now at $17,600 dollars to replace. I don't have that kind of money at this time. My other motor is still in rappings waiting to be built. I have raced for 11 years, the accusump has saved my motor twice. This is from roadracing and autocross. The car gets 98% of the time on the track. For a street car, you could get away without it. Most of these motors only go 20-60K miles before a rebuild. I have gone about 400 hours of abuse on the 452 motor, the new motor is in the 80 hour range. The 452 bottom end was perfect before the change to a bigger stoker kit. The orignial coating was still on the rod bearings in some places, same with mains 2 and 4. I also ran high oil pressure in this motor. 35-40 at idle 75-80 at track speed. When you have spent this much money, what is another $400.00 dollars for insurance??

Jerry Clayton doesn't believe in them and that is OK with ME.

How ever he may have alot more money than me and spare parts. I use the accusump for autocross and roadracing to help keep the oil pressure stable in high "G" turns. Jerry may have had a problem with his setup, I don't know, he may run a GM motor in his car, it say that on his info, again I don't know. Better oiling system in an LS1 motor also. FE imo need alot of help.
This is what has worked for me over the last 11 years I am not changing a thing. I do a little more maintainance and checking the gears on the distributor and cams camshaft after every race. No failures at this time. The oil pump drive is alot a billet piece. A bigger pin is in the gear on the distributor also. Getting oil is key to extending the life of the gears. Also endplay on the cams shaft. If it's not broken, then leave if ALONE. I have been told for years about running high oil pressure with both FE rods and BBC rods, 135 psi cold and 1,200 rpms, they are just like a women, it takes a little time to warm them up before you----@#$%^**^%$ out of them. They seam to be happy with this treatment. I like and will stay with the preoiling system. I am adding one to my stroker motor(383) that is going in my tow rig. I see no down side to this either. I don't like it DRY, never did, never will.

Rick L. Ps you now own me a Coke.

jwd Jim I have had motors sit built for 6 months and unless they had perlube on the surfaces, the top 3/4 of the bearings are dry. You are also running a windsor motor which has about 15 pounds less weight than a FE motor assembly. FE rods use the same size bearing as you and weight 200 - 400 more grams than your rods. Synthesis oil does the same thing about NOT clinging to parts in a motor. This is why a synthesis motor makes more power. The more polished the surface the easier it is for the oil to shed off the part. Thats the idea with getting the oil back to the oil pan. Maybe in WA conditions are different, but in Jersey the oil always goes to the pan and bottom of the bearings. I think it is called gravity, I could be wrong and don't work at NASA. I did stay at a Holiday Inn last year. I do have 30 years of wrenching, building and racing. I also use clinging oils in my motors. another fun subject, for another time.

Have a good day. Rick L.

I have one contribution to this thread. My replica is not a Kirkham and my engine is based on a 351W. During my first day of autocross racing, my distributor shaft broke when the oil pump siezed due to lack of oil. While the engine was being rebuilt with a better oil pan, I installed a 3 quart Accusump. With many more days of track time since then, I've never had a problem with low oil pressure. Incidentally, I also put a big red low oil pressure warning light right in front of me on the dash.

Ricky- Damn,....I always owe you something !

"I have been told for years about running high oil pressure with both FE rods and BBC rods, 135 psi cold and 1,200 rpms"

135 psi,.....really ? Is that something that the FE needs ?
I should be building the alum. 482 soon so, I'm concerned about EVERYTHING !
Since it will be the most $$$ engine I've ever built, even the sprint engine.

Sorry I missed the call but, you didn't LEAVE A MESSAGE !

I don't have caller ID buddy. Call anytime.

RodKnock-I also let the motor warm up before I put a load on it. My wife always says, "I'll sit and watch my garden show so, let me know when your baby is ready to go" lol !

At first start up after winter, I un-plug the MSD box (under my dash) and crank the engine until pressure is up. It does take several revolutions.

Here's my $0.02. I'm not an engine builder like many here on CC, but I have basically the same reasoning as you. My engine takes a few cranks before it starts, it gets oil pressure before ignition and then after it starts I bring the idle immediately up to 1,500 rpm +/- and warm up the car for a couple of minutes. I will never say never, but I just think the pre-oiler adds one more complexity, where one isn't needed.
