1050 ccs of fuel!

[Strick-9]

While my engine is down, I decided to take my pump to have it balanced on a pump stand.



The pump guy was shocked when setting it up. I had one very weak cylinder. He balanced all the other cylinders to the weak one and ended up putting out 1050ccs/ 1000 strokes.



He said we are leaving 150-200 ccs on the table by having that one weak cylinder.



He said he didn't know the pumps were capable of that much volume. I showed him a few of my censored modifications and then he understood.



I'm still running 191 delivery valves too. I have some customized ones that MIGHT increase the fuel delivery. We'll see.



It would be nice to get that 150ccs extra though. Isn't more always better.



What are other people putting out?

I cant keep up with you guys. Twin turbos, 1000+ cc pumps, camshafts, etc.



I guess Im falling behind here as the minutes go by.



Congrats on the pump work. My poor old pump is fried, I have found a lot of metal shavings in it lately in the plunger and barrel area when I change out DV's and such. Its slowly croaking on me as I drive. My fault though, the 4k plus runs daily are taking the toll. I thought I would be the first on the pump stand in these parts... . Chris you beat me to it! Dern it, slow down some so I can catch up.

Excuse me?

Another Kat Diesel in the 11:00s!!!!!!!!!!!!!!





Yer killin me!Oo.

LMFAO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[msmtd]

1050cc's,eh? Yea,sure,whatever..... Who was running your pump? I don't buy it!

Oo. LOL!

Something's wrong.



Jim Leonard (TDR issue 24, p 72) has his stock pump calibrated. It averaged 174. 4 c. c per 25 strokes.



At 1000 strokes it would be 6970 c. c. ?



Chris,



Could it be 1050 c. c @ 100 strokes?



This would give you a healthy 262. 5 c. c @ 25 strokes vs. a Stock pump at 174. 4 c. c @ 25 strokes.

60 ft .019??????????? sure

what is that a top fuel?

I never said it was right... thats just the slips that were handed me. The slip on the right the owner of the mustangI raced said I beat him by 3 car lengths at the end.



As you can see in the slip on the left... . I was so fast the 60ft time didn't even register!

 

[KLockliear]

Now you're getting somewhere Chris. Lawrences old pump made 1074cc/1000. The new one is over 1500.

 

[Strick-9]

Keith,



Thanks for chiming in. I knew that Lawrence was over 1000 cc's back in December when I visited with you guys that Monday after the dyno event.



These skeptics are downright brutal. I knew that when MY6 or Joe or you posted some REAL numbers, they would be quieted down.



Thanks for rescuing me from the depths of TDR criticism.



I'd still like some other people to post their numbers for comparison sake. If I just had the airflow and injectors to complete the rest of the puzzle, I might get somewhere.

Chris, I never said it can't be done, I just don't buy that your stock turboed propaned, nossed, stock turboed dynoed at 428 hp flowed over 1000 ccs. Maybe after you took it off and messed with it, but not while it was on your truck.

That is tractor pulling ccs.



It is nice to see that Piers helped DD finally flow some fuel!

Way to go Piers!Oo.

 

[Don M]

If the low fuel output of the Lawrence's old pump was a wimpy 1074/1000 and they still managed to stomp the rest of the crowd at most dyno events, the new pump should prove close to impossible to catch.



Chris had internal engine damage that rivaled most I have ever seen before and still be running. Slopped out rings and piston ring grooves, crappy valve job, etc. can lower HP levels a lot. The number 6 bearing was probably close to metal to metal as well.



Chris, I knew the numbers were right I was waiting for others to comment first.



Ill never catch up... ... ... or will I?

Gene,



I was humiliated at the dyno event with only 428HP. I know you're a sled puller, so you may not understand my comparison here. I measure performance of my truck by measuring the speed over a given distance. The location is near my house and easy to access. My results are always within 1mph. Over the last two months I steadily lost power and my speed dropped from 88mph to 80mph the day of the dyno event. The stretch is slightly longer than 1/8 mile but also uphill. That's a MAJOR loss of power. My propane is usually about 80HP. Even running the propane and NOS couldn't get me back to my 88mph. That's when I knew something was seriously wrong with the truck. I know that I lost over 100 HP. But I didn't back down from the dyno event and I'm not hiding my HP numbers even though I'm embarrassed of them.



So I apologize if 1050 cc's of fuel doesn't equal 428 HP in your book. I made ZERO modifications to the pump before delivering it to the pump shop.



BTW, what does your pump put out? I want to install the custom delivery valves and put it back on the stand, but with the money I'm sinking in the motor, I can't justify it right now. I'm sure you can understand that given your recent expenditures. I'll know by the smoke levels and speed whether they help or not.



Don,

You know you're right there with me. You just need to get on a pump stand to prove it. Your pump is identical to mine except for two mods. And you know one of them.

[MY6EATSV8'S]

Chris to tell you the truth I have no Idea how much fuel mine puts out. BD built it when Piers worked there, they didn't keep records of the fuel output. I know it made 497hp the last time to the dyno on the first pull, averaged in the 48* range for the next 7 or so pulls. I also know the next version of my motor is going to put out more.

 

[Sled Puller]

I can't quite remember, under 300 I think with the 191's.



Have not tested it with Mitchells D valves. I know it is more because of smoke and EGT. How much? No clue.



Are you SURE you are using the correct measuring unit?





How many Horsepower was the motor on the pump stand?

 

[Cummins Corvette]

I don't understand this cc's of fuel bit. Is that measurement of 1000 cc's of fuel/1000 strokes per cylinder, or for the whole pump? I know of one shop who rates their pumps on a per cylinder basis. They are getting 260 cc's per 1000 strokes per cylinder. Then they would be the best pump shop in the world, making a 180 hp pump put out 1560 cc's per 1000 strokes when adding all the cylinders together. I don't understand this. I know my stock pump put out 88 cc's of fuel/1000 strokes per cylinder. (It says right on the engine that it uses 88 mm3 per stroke=88cc's per 1000 strokes per cylinder). If I am getting all this right, then other Chris's pump is putting out over 11 times the amount of fuel that my pump put out in stock form. I know that the efficiency at that level of hp isn't what it was at the stock power, but if it was, he would have over 2000 hp. What gives?

April Fool Trollers CAnderson!

They is tryin to get us to tell our secrets to see if they can compare!



They can't!

Gene, what are you talking about?



CAnderson, it's per cylinder.

 

[Pthomas]

Keep your secrets !

we all have our so called "secrets"but i call them learned knowledge and thats half the fun i enjoy very much! to LEARN AND PROGRESS!

Chris (strick 9)you have taught me one very valuable lesson dont be affraid of the P7100.

they all got the fuel capability and it isnt hard to get!

the hard part is getting the AIR and FUEL ratio just right!

maby without any drugs? thats my goals

 

[Strick-9]

What's wild is this. At 3000 rpm, 1050 cc's per stroke is 2. 5 GPM of fuel flow! My kitchen sink flows just over 2. 0 GPM.



No wonder I had to add an auxillary fuel supply system to keep supply pressure from falling off the gauge under full throttle.
