Competition max CC of fuel from 215HP pump

[RoadGoesOnForever]

DPS, ... lol, that statement is BS from start to finish! 1. ) Never agree with GENE, 2. ) nobody with a garage out of their house has a pump stand (at least not many), 3. ) A 400 cc pump is not better than a 650 cc pump with propper air. 4. ) there is no such thing as "quick" fuel delivery, just more fuel earlier and that is controlled by AFC or how fast your foot hits the floor. If you don't think so ask Joe. D, Piers, or K. Locklier, big HP is always begun with big cc's. ... ... I bet Schied has over 400 cc's ,lol.

By quicker I think he meant a faster rate (as in faster cam velocity in the pump) resulting in higher injection pressure. I may be wrong though.

 

[DPS]

Well excuse me. Fuel delivery is key period. A built pump, that has a custom ground cam with steeper ramps, and big plungers will deliver fuel to the injector faster than a stock pump that is calibrated for more CC's. THe faster the fuel is injected the more time it has to burn near TDC equaling more pressure on the down stroke... hence producing more power. If you take a good setup, put a tuned pump on run it on the dyno, then put a stock pump in its place it will take more cc's of fuel to get the same hp if you can even get it to the same hp. As for back yard pump shops, I hear about them all the time in my local area i. e. Indiana. I can name 3 right off the top of my head. . But! it does still take air, no amount of fuel will compensate for a bad setup. THe only point I am trying to make is that just because a pump will push X cc's of fuel doesn't mean it is equal to all other pumps at the same number of cc's

P. S. WHy the personal attack???? I didn't go after anyone on this thread???? Just because Gene might have made a decent point doesn't justify your blanket, unfounded attack.

I am stepping out of this debate before it turns into a transmission war thread, or in this case a p-pump set up war thread. Everyone has there own idea's and most are right, if everyone actually read what was being said here, we're all pretty much in agreement, just saying things differently. I will end it like this, each to his own, or his own shop or his own set up.

That's funny, I've never heard of any winning trucks running a Brown's Diesel pump... . or Brown's Diesel anything Although he made reference to Donnelly and Locklier.....

Alright guys... been a month or so since this was last talked about (hopefully things have cooled down a little!!!)



Anyway, my pump is now in the shop in pieces... pretty much know what Im going with I am just trying to get an idea a well built pump with plungers/barrels/cut cam should pull CC's wise?



Mine is a 96 215hp pump and am throwing as much into it as possible without having to go and robb a bank :--)



Everyone above was saying a 215 is a waste to do that to or not worth it but if thats the pump that you have (came with your engine) you arn't loosing anything using it are ya????



Here are a few questions for all you P-pump guro's out there-



With a pump like above when dealing with Delivery Valves how far should you go? I have heard that going with Lazer cuts will just give you crazy fuel and unless you have the largest size of twins out there they are a waste of $$$ I was thinking of just going with 191's... should be okay huh



About the govener... I have heard of doing two things and what your opinions. I am wanting to rev to 5000rpm. I have heard I can just get a 5GSK and install it or I could get a set of 4GSK springs and take weight off the actual govenor making it lighter and there for reving up higher then 4K. Which is best or is the one just a race/pulling pump mod?



Hopefully someone will be able to answer those questions.

Do you have the valvetrain to run 5000 rpm?

 

[RyanB]

Yes the valve train and the rest of the engine will be set for that figure

As far as 215 pump DV choices, I think I read that Fulmer uses 191s for normal use and the cuts when he dynos. I am guessing 'cause the cut ones are too much for street with a 215, but I am a LONG ways from knowing very much about P-pump tuning...

Actually it's 181's for the street and . 022's for the dyno or both. 27 HP gain from 181's to 022's on my last outing and the 022's are a pain to try and drive on the street. You can get away with them if your running say 370's but if you put a real injector in there it's allot different.

Thats funny Jim, I'm sure I remember a post or two on this board that insisted there was no HP change, just lots of smoke from stock DVs to bigguns.

You keep proving them wrong! :-laf



Say, are your holders stock or hogged out? Line size?

 

[Cooker]

Say, are your holders stock or hogged out? ?

Good question



Jim your profile says PDR 175 pump. I thought you were running a PDR Race/Stupid Pump?

(Line size)There is a topic I have been thinking about alot lately but keep forgetting to post about. What what kind of pump cc's would it be best to jump up to the larger size? if I am going with the 13mm's P&B's and the cam would I be best to jump up to them? any disadvantages to them?

Here is what I have so far: That change on the dyno was from stock holders and 181's to . 022's and . 093 holders... . lines are stock. I think the holder deal has more to do with being easier on the pump.



Lines: The only thing I have ever done with the . 093 lines is loose power on the dyno, on the street I like them better, must have something to do with fill time..... who knows. I will test this again on back to back dyno runs, I hope to buy a day on the dyno before too long and test multiple items..... lines, DV's and Timing.

Why don't you just buy a dyno Jim? It may be cheaper for you :-laf . Kidding... I love you man.

Do you realize that in the last 2 years I've only made about 12 dyno pulls. A dyno cost half what my house does and I don't have a shop that big... ... wow that would be too cool.



Jim

 

[Jim Fulmer]

Anyone else have info on bigger lines they would like to share?



I'd like to try a set of . 084's, or would trade my . 093's for them.



In the sled puller or racing world I believe the bigger lines are beneficial.



Jim

 

[RyanB]

Well, thats the thing with me. The truck will now be mainly a puller and Im not to concerned about the street (but I don't want it dyiing on my and running like crap at the stop light). I also am saving $180 I thought I had to have for a core on injectores because I sold my 215's last year... turns out I can use my set of 1st gen injectors so I get the credit of $180 which is have the price of the lines!!!!



Should I make the jump to the next size up or even two???



Ryan

 

[Jim Fulmer]

I would say keep that thought in your hat. I do know Piers and Jason Burton tried the . 093 lines and didn't gain HP but gained T/Q, I've just never had good luck there.



Another thing though, when going out to M/M 04' I had the . 093 lines on and stopped in New Mexico and changed them out because it was driving me crazy. Bigger lines make it Governor spring bounce at anything over 2K and it's worse at high altitude. Big Injectors will do this too to an extent, the smaller of either the better it cruises across country at 2K... ..... Autopilot/ Autothrottles engaged
