Engine/Transmission (1994 - 1998) which makes more hp?

[98slushbox]

If a 160 pump and a 215 pump had the same mods done to it would the 215 outfuel it and make more power? reason i'm asking is that I want to get a different pump but dont know if i should just get a 215 or look into a stupid pump or somehting to that effect. My 160 pump now has 0 plate, 4000gsk, and laser cut dv's. Would a 215 be better with those upgrades or something different?

Let me put it to you like this, currently for testing in my truck is a 215 with a cut plate, 4K's, 181 DV's, timing..... high and my EDM's and it would blow that B-1 through the hood... ... . it's that big of a difference, if that is not enough then I would go to a race pump (stupid version)

I don't know what the 215 flows number wise with those mods. . My 160 flowed 450cc's at only 3200 rpm. .

The 215 pumps can put out WAY more fuel from what I have seen!

Back to a 215 Jim is the testing for a guy out this way? (shoulders as wide as I am tall )

from my understanding the 215 and the 160 have different internals... that is what i have been told and i assumed they meant barrel size and so forth. just picked up a book today on bosch pumps that explains how they work. did you know the p7100 flows almost 2 times as much as the vp44 according to bosch

 

[98slushbox]

Did not know that. Figured they flowed alot more but not how much more.

I had heard the internals cam, barrels, plungers etc... . were different but wasnt sure.



Fulmer,

With the upgrades I have in my 160 now I can rail on my truck all day and havent blew the B-1 up yet, so i guess I am missing out on alot of fuel. I can make about 50-55 lbs. of boost now. I think I will just look for a 215 for now instead of getting a stupid pump. thanks for the input from everyone

The 215 has the best cam profile of the bunch, hence it makes the best power. A Stoopid pump starts with a P7100 housing as installed on the dodge but uses bigger barrels. 160 pumps are usually used as the plungers, barrels and DV's all get tossed. Looking at the pump stroke vs pump timing on Fritz's site, the 160 pump has more stroke than the 215 but I'm guessing that it's got smaller barrels.



Just a theory...

I'd like to know the name of that book so I can order it, might learn something..... quiet sure I will.

the 160 pump has more stroke than the 215 but I'm guessing that it's got smaller barrels They all have 12mm P&B's but the 215's are a slightly different design, the cam is better for fill time and the Governor is lighter, doesn't sound like much but it is.



If you add a good 215 to your 160 truck you will have to add a wastegate if your already making 50-55 psi, that's actually past a B-1's sweet area, if you check drive pressure you should see it climbing fast at that point!



Ok here is some more data, #2 only makes 82 psi on my truck at 1800+ degrees... ..... 150 degrees air temp at the intake hat, 370's are a little less that that but still big numbers.

With my 4gsk I can only get about 3700 out of it, guess it may be a weak kit or i guess the pump cant run that and a 215 will alot easier with the better components.

I need to get my truck on the dyno to see what i am actually making, but with the drive pressure thing, do you think the charger is coming up too late to make peak power? Where do you check drive pressure at, the exh manifold?

I'm assuming your running inj quite larger than 370s and twins to make that boost. I guess I would see alot more hp with the B-1 if I had more fuel but have to wastegate it?

[DavidTD]

I agree with Jim on the 215 vs 160.



Slush, have you ever been on a dyno? If not, I'd do that before I did anything. If you max at 3700 with 4k springs, they need adjusting. You might be surprised what the dyno can tell you as far as tuning what you have for more power.



How much power are you looking for? I've seen 556hp with a 160, stock deliveries, spring kit, injectors, and S300 at 40 psi.

A 160 pump has the potential to make over 800cc's of fuel... . That's more than we street strip guys could imagine burning right now. . I just had 13mm plungers and barrels installed in my 160. . The same shop just completed a 215 before mine. . Both are flowing within a few cc's. . I don't know much about this, though I was recently facing the same delima. . The cheapest 215 I found was over $700. . For a few hundred more than that, my pump was made to flow much more fuel than a 215 could without plungers and barrels. . I was just told I'd never have to worry about lack of fuel. . Before you drop the cash on a 215, I'd spend a little extra and make your 160 crazy. . You'd have a lot more fuel for your money to play with. .

DavidTD,

I've never had this truck on the dyno yet. I agree, i guess i do need to get on one before I jump to conclusions. I've had a 500rwhp truck before, but it was with an auto, but it doesnt feel like its close to that really. I would atleast hit that again if not more. As far as the governor kit goes, the truck idles at around 800 rpms now, i figured thats about right. Should i try turning them a little, if so which way?



Morse,

That sounds like that would be a great route for me to go. I'm assuming you drive your truck on the street? Are you running a B-1, but going to twins? You had less than a thousand in pump work? I've priced a couple 215's and got the same prices around $800. Where did you have your pump done at?

Morse who did your P&B job? PM me with some pricing. In talking with people(scheid, and others) The 215 will make more power, the biggest thing they said is the internals of the 215 allow better high end(above 3600 rpm) fueling. I had a 911 pump(180HP) and I opted for the 215 pump. I found mine for $750. Should be in route.
